Background of the invention

To facilitate the extraction of hydrocarbons from oil and gas wells, the subterranean formations surrounding such wells can be hydraulically fractured. Hydraulic fracturing can be used to create fractures

5 In subsurface formations to allow oil and/or gas to move toward the well. The formation is fractured by introducing a specially engineered fluid, sometimes referred to as fracturing fluid or fracturing slurry, at high pressure and high flow rates into the formation via one or more wellbores. Fracture fluids can be loaded with proppant, which is a particle size that can be mixed with the fracture fluid fluids.

10 To help form a sufficient conduit to produce hydrocarbons from the formation to the wellbore. The proppant material may include naturally occurring grains of sand or gravel, synthetic proppant materials, for example fibers or sand coated with resin, high-strength ceramic materials, for example sintered bauxite, Or other suitable materials. The proppant aggregates heterogeneously or homogeneously

15 Inside cracks to support the opening of cracks formed in the formation. Effectively, the proppant forms levels of permeable ducts through which production fluids can flow into the wellbore.

At the well site, proppant and other fracture fluid components are mixed at the low-pressure side of the system. Oilfield materials are often delivered from storage facilities to a mixer

20 Using pneumatic systems, oil field materials are blown away. A water-based fluid is added and the resulting fracture fluid is delivered downhole under high pressure. However, proppant circulation tends to occur

٦٠٣٠

Before mixing, it leads to the formation of basic dust when moving the proppant material into the mixer using blowers. As a result, dust control devices, for example vacuums, are used in an attempt to control dust. The variety of equipment used in the process also tends to create a large space at the well site, and operating the equipment is generally a laborious process5 manually.

General description of the invention

In general, the present disclosure provides a system and method that facilitates the handling of oil field materials in a space-efficient manner. The oilfield material is stored in at least one warehouse that can allow the use of gravity to feed the oilfield material to a mixing system or other suitable equipment. In many applications, this is done

10 Delivery of oil field material to each warehouse without blowers. A mobile carrier structure, receiving one or more modular reservoirs, is disclosed at the well site. Each modular reservoir is movable and can be attached to a load-bearing structure that can be transported to the well site separately via a connection that allows controlled movement of the modular reservoir during its stay. Once engaged, the modular warehouse can be pivoted to an elevated or upright position

15 Load-bearing structure. The oil field material is then moved to an internal space of the warehouse, and the effect of gravity can be utilized to feed the oil field material to a mixer or other equipment in a controlled manner.

However, many modifications can be made without departing materially from the guidance of this statement. Accordingly, such amendments are intended to be included in the scope of this disclosure as defined in the Safeguards.

Occurrences of the phrase “in an embodiment” in various places in the standard do not necessarily refer to the same embodiment.

The present disclosure generally includes a method and methodology for facilitating the handling of oil field materials in a space-efficient manner. In one embodiment, oil field materials can be transported to a well site by suitable trucks and carried

Loading At least one airless modular bunker to carry oilfield material. For example, oilfield material can be moved in a group of modular warehouses using vertical conveyors to move the oilfield material without blowers. In some embodiments, each modular warehouse includes an external housing that defines an enclosed interior space

15 To receive oil field material. A corresponding vertical conveyor is placed within the enclosure and is used to lift the oilfield material from the warehouse inlet, eg a hopper, to the top of the modular warehouse without using airflow to carry the oilfield material. Once the oilfield material is placed inside the existing modular warehouse, the flow of the oilfield material outward through the warehouse outlet can be controlled by the influence of gravity.

20 Selectively release the required amount of material into a mixing system or other suitable equipment located below the modular warehouse.

According to one example, an RC warehouse is designed as a modular warehouse that can be carried to the well site by road truck before being installed in a generally upright position on the load-bearing structure. Truck refers to a transport vehicle, such as an articulated truck

25 Truck has a trailer pulled by a tractor. In this example, the modular warehouse is loaded by

٦٠٣٠

-٧-

Truck trailer. However, the truck may also include a straight truck or other suitable truck designed to carry the modular warehouse and for transporting the modular warehouse over public roads. The load-bearing structure can be designed in such a way as to allow the warehouse to be erected from its side position on the truck to an upright position, for example a reclining position, a position at a well site. However, it should

5 Understand that in other embodiments, cranes may be used to lift the modular warehouse and place the modular warehouse on a load-bearing structure. The use of existing reservoirs provides an effective solution for proppant delivery in many applications. Gravity makes the oilfield material flow efficiently downward to the required equipment, such as a mixing system.

The load-bearing structure can be designed in a variety of shapes and configurations to hold individual warehouses consisting of

10 Modules or a group of warehouses composed of modules. For example, the structure can be built

A load bearing structure consisting of supports arranged in an A-frame or other type of structure that can hold and hold at least one modular warehouse in the desired upright position. In some

Applications At a minimum, the load-bearing structure is designed to interlock each modular warehouse while it is in use

The modular warehouse is placed on a transport truck. This would enable axial rotation

15 For a modular warehouse, move straight up from the truck to its current operating position. maybe

Also, building the load-bearing structure to carry each warehouse, consisting of units of sufficient height to allow the feeding of oil field material by gravity through a feeding device with a lower end and in the portable mixer placed at the bottom. In some applications, load cells are included in the load-bearing structure generated by each modular warehouse, allowing the amount of oilfield material to be tracked in each unit.

20 Modular warehouse. In one embodiment, the load-bearing structure is a mobile load-bearing structure configured as a trailer with wheels and a gooseneck portion for connection to a truck. In this model, the goose-neck section can be converted into a ramp to assist in placing a mixing system beneath modular tanks. In another embodiment, the mixing system may be integrated on the roof of the mobile load-bearing structure.

In some embodiments, a conveyor may be used, such as a mechanical belt conveyor

25 Mechanical belt conveyor, to move unloaded oil field material from gravity pump conveyance

٦٠٣٠

Gravity dump in a hopper with the intake inlet of a vertical conveyor enclosed within the modular warehouse. The mechanical belt conveyor can be supported on top of an oilfield material hauling trailer with several nozzles, or trailer hauling can be installed with the mechanical belt conveyor, or other types of conveyors can be used, such as tailgates and active undercarriages. For example, it could

5 The RC conveyor shall include a spike hopper or other type of RC conveyor that can transport oilfield material to an upper end of the modular warehouse at a significant distance, for example 30 to 70 feet, above the surface of the well site. The conveyor transporting the oilfield material to the depot and the RC conveyor can be enclosed to provide a dust-free solution for handling oilfield material at much higher rates of speed with greater energy efficiency and less fatigue than is achieved using existing conveyor systems, for example

10 Example: blower, of the type that works with air pressure and conveyance systems. To increase the storage capacity of a modular warehouse compared to a cylindrical silo, the outer housing can have a highly rectangular shape defined by four corners (it can form pointed vertices or rounded shapes). The modular warehouse can be transported on a trailer with a hitch Curved as best shown in Figure 5, to increase

15 Additional storage capacity for a modular warehouse While it can also be transported by truck, the vertical conveyor can be extended beyond the top of the outer housing and offset to a corner to avoid the gooseneck of trailer.

Based on the variables of a particular fracturing process, a group of warehouses consisting of units can be grouped together to provide means of feeding a group of warehouses composed of units.

20 From oilfield material units to a common area, for example to a truck-mounted mixing system incorporating a proppant metering/rate control system, or another portable mixer or mixing system located beneath the bottom of modular warehouses. To reduce the space required at the well site for a group of modular warehouses, the common area can be located under the outer housings of the warehouses.

25 Consisting of units. In this example, the external housings of the modular warehouses are installed with

٦٠٣٠

-٩-

Common area. Additionally, some or all of the modular repositories can be divided into partitions. In some applications, individual modular warehouses can include a combination of internal compartments to hold different types of oilfield materials. Individual warehouses can also be divided into main storage volumes and secondary storage volumes located below the volumes

5 Main storage. In the following example, the main storage chamber can be used to gravity feed oilfield material to the inlet feeder for distribution in the mixing system. Some systems may use a belt feeder or other type of feeder system instead of gravity feed. The secondary storage compartment can be exposed to the internal arc conveyor and the backing material can be continuously lifted from the secondary storage compartment and unloaded into the main storage compartment. In some applications, it may

10 The secondary or other compartments of the modular warehouse must have separate features that enable independent filling of those specific compartments. Additionally, inlet feeders can be designed with controllable mechanisms, for example gates, that are adjustable to control the outflow of oilfield material.

Modular warehouses can be designed in a variety of sizes and shapes, including shapes

15 Cylindrical or rectangular shapes, selected to enable transportation by a suitable truck on the road. For example, modular repositories can vary in size depending on the proppant material and delivery plan for a particular fracturing operation, but one example of a suitable modular repository can accommodate 2,000-4,000 cubic feet of oilfield material. In some systems, modular warehouses are provided with sufficient clearance on the underside

20 To form an unobstructed passage to enable a portable blending system, such as a truck-mounted mixing system, to be driven under a system of modular common bunkers to receive oilfield material by gravity feeding. For example, a portable mixing system may be mounted on a truck trailer that is held in place under the feed outlet in a group of modular bunkers. In some models,

25 Modular warehouses can be designed as freestanding and modular warehouses

-١٠-

Other, modular warehouses can be designed to be placed on a load-bearing structure that holds the modular warehouses to a desired height. In one embodiment the mixing system may be mounted on a skid to be transported on a trailer to the wellsite and then placed under the storage system by a suitable mechanical device, such as a winch.

Including engines, various motors, or other devices.

Referring generally to Figure 1, an embodiment of a proppant delivery system to form suitable slurry for formation fractures, in situ at the well site, is illustrated. For example, a proppant delivery system can include many types of equipment, including vehicles, containers

20 Storage, material handling equipment, pumps, control systems, and other equipment designed to facilitate the fracturing process.

In the example of Figure 1, a proppant delivery system 20 is shown in position at a well location 22 comprising a well 24 such that at least one wellbore 26 extends downward into a reservoir/formation. The proppant delivery system 20 can include many types and types of equipment, and can

25 The types or equipment may vary from one cracking process to another. For example, it could include

-١١-

Backing material delivery system 20 on at least one modular warehouse 28, for example a group of modular warehouses that can be transported on the road by trucks that can operate on public roads. The 28-unit warehouses are designed to store oil field material such as proppant used to support fracture opening when a subterranean formation is fractured.

5 Earth, or a vicinity used to increase the viscosity of a hydraulic fracturing fluid. In the example shown, a plurality of modular warehouses 28 receive oilfield material via conveyors 30, for example belt conveyors, and the oilfield material is lifted to an upper portion 31 of each modular warehouse 28 by corresponding dock conveyors 32. That the conveyors 30 and the anchor conveyors 32 operate by carrying the oilfield material instead of blowing the oilfield material to avoid corrosion

10 Ingredients and dusting the area. Additionally, the conveyors 30 and the bed conveyors 32 can be encased to further reduce dust while the oilfield material is being delivered from the unloading area 34 and into the modular warehouses 28.

As shown, oilfield material transport trucks 36 can be used to deliver oilfield material to the unloading area 34. In this example, the trucks 36 are tractor-trailer trucks.

15 Trailer Trucks includes 37 trailers that can be rested on a selected section of conveyor

30 conveyor. The trailers 37 may be gravity-fed trailers or other types of trailers that can transport the oilfield material to the well site 22. The trailers may be operated to release the oilfield material onto a belt or other suitable carrier of the selected conveyor 30 for transport to the associated warehouse consisting of Units or warehouses 28 along an encapsulated track within the conveyor 30.

20 In this example, the proppant delivery system 20 may include a variety of other components including water tanks (not shown) to supply water that is mixed with the oilfield material to form a hydraulic fracturing fluid, for example a proppant slurry slurry, which can be pumped downhole into the wellbore 26 by means of a set of pumps (not shown). For example, the pumps can be combination pumps

25 On a truck, for example pumping systems mounted on truck trailers

٦٠٣٠

-١٢-

Truck trailers are designed for transportation on the road. Multiple pumps may be coupled to a common manifold (not shown) designed to deliver hydraulic fracturing fluid to the wellbore 26. The proppant delivery system 20 may also include a mixing system 44 designed to mix oilfield material transported from the component reservoirs Of 28 units.

5 For example, the mixing system 44 may be a portable blender, such as a truck-mounted blender or a skid mounted blender. In the specific example shown, the mixing system 44 is mounted on a truck trailer 46 that can be driven, for example backed, into a common area 47 (shown in Figure 3) that is positioned below or adjacent to the modular warehouses 28. A delivery system may also be included Support filler material 20 on a variety of

10 Other components, such as a control facility 48 and/or other components designed to facilitate a particular cracking process. In one embodiment, the shared area 47 is located below the outer housings 49 of the modular warehouses 28. In this embodiment, the outer housings 49 of the modular warehouses 28 overlap the common area 47.

Referring generally to Figure 2, a model of 28 modular warehouses is illustrated

15 Paired together into a cooperative unit. In this example, a group of modular warehouses 28, for example four modular warehouses 28, are coupled together on a modular load-bearing structure, or chassis, 50 which may be mounted on a mat system 52 which may be placed on A border, such as a border of concrete, gravel, or the like. The 52 mat system distributes the load from the 28 modular warehouses on the floor. Can be installed

20 The modular warehouses 28 are demountable in a generally upright or anchored direction on the load-bearing structure 50. The load-bearing structure 50 is configured with a plurality of receiving areas 54 on which individual modular warehouses 28 can be installed in an upright or anchored direction. in general. The load-bearing structure 50 and the warehouse receiving areas 54 can be designed to raise the modular warehouses 28 to a sufficient height to permit movement of the mixing system.

28 sufficiently within common area 47 to receive a controlled outflow of oilfield material. For example, the load-bearing structure 50 may be designed to allow a truck-mounted mixing system 44 to be driven, for example supported, into position beneath the modular warehouses 28, as shown. Additionally, the footnote can be configured in a variety of sizes and shapes, including:

5 These are cement pads, compacted aggregate pads, pads constructed in portable structures, mixtures of these various structural elements, and/or other types of padding suitable for holding a range of warehouses consisting of 28 units.

In the example shown, each of the 28 modular warehouses can be configured with a structure

10 Repository 56 holds an outer housing 49 that defines an enclosed internal space 60 to hold oilfield material 62 (see also Figure 3). Depending on the fracturing process, oilfield material 62 can include naturally occurring sand or gravel grains, synthetic proppant materials, Sands covered with resin, highly resistant ceramic materials, for example sintered bauxite, and other solid materials such as fibers, mica, mixtures of different sized oil field materials, and mixtures of different types of field materials.

15 Oil, and/or other suitable oil field materials. In some applications, the modular bunkers 28 or each of the modular bunkers 28 may be subdivided into compartments 64 designed to hold various types of oil field materials 62 that can be selectively released from the modular bunker 28 and mixed by the mixing system 44. Each is designed to A truss conveyor 32 is enclosed for lifting oilfield material (e.g., with or without blowing) from an inlet 66, e.g. the inlet of a hopper, positioned at part

20 Lower 68 to upper discharge portion 70 for release into an enclosed interior space 60 through a vertical conveyor head 72. In some embodiments, the conveyor head 72 may have a pivotable discharge or otherwise movable discharge device that can be selectively controlled to deliver the desired oilfield material to a corresponding desired compartment.

Also referring to Figure 3, the RC conveyor 32 may be located within an enclosed interior space 60 in such a way as to limit dust intrusion while providing a regular modular unit that can be easily transported by an on-road truck, such as a truck 36 with a suitably designed trailer. The RC 32 bus can also be configured in a variety of configurations. For example, the RC bus can be configured as 32

5 As a height hopper 74 having a set of buckets 75 transported in a continuous loop to lift oilfield material 62 from an inlet 66 to an overhead discharge portion 70 for discharge into an enclosed internal space 60 by means of a vertical conveyor 72. The outflow may be from oilfield material 62 To the mixing system 44 through an outlet, for example a feeder 76, and the amount of flow out through the feed means 76 can be controlled by a suitable outflow control mechanism 78. 10 For example, the mixing system 44 can include a hopper 79-1 having an inlet 79-2 positioned below the feeder 76. In one embodiment, the outer housing 58 interfaces with the inlet 79-2 of the hopper 79-1. The inlet 79-2 of the hopper 79-1 can have a width 79-3 of up to 12 feet, preferably between 8 feet and 8.5 feet. The hopper 79-1 may also have an outflow control mechanism 79-4 that is identical to the outflow control mechanism 78. For example, it may

15 The outflow control mechanisms 78 and 79-4 include a controllable gate, for example a hydraulic gate, control valve, or other flow control mechanism operated by a control facility 48 or by another suitable control system. In this example, the oil field material 62 being gravity-fed is controlled by the feeding device 76 and the amount of outflow is controlled by an outflow control mechanism 78. In one embodiment, the amount of material can be regulated

20 Oil field 62 that is discharged to the mixer 79-5 of the mixing system 44 by both outflow control mechanisms 78 and 79-4. In this case, the outflow control mechanism 79-4 may be maintained in a fixed open position while the outflow control mechanism 78 is regulated in real time by the control facility 48 to control the amount of oilfield material 62 discharged to the homogenizer 79. 5. Check whether the feeding method 76 is within the hopper barriers 79-1, when

25 The hopper 79-1 is filled with oilfield material 62, the oilfield material 62 compresses the feed means 76 and forms a plug. In this way, the outflow control mechanism 79-4 is self-regulating and can

-١٥-

The outflow control mechanism 78 and control attachment 48 control only the amount of oilfield material 62 discharged into the homogenizer 79-5.

Referring generally to Figure 4, an example of a load-bearing structure 50 is illustrated. In this example, the load-bearing structure 50 includes a plurality of supports 82 that are connected by appropriate fastening methods 5 to form a strong, stable structure to hold at least one modular warehouse 28.

Fastening methods may use welds, bolt and nut fasteners, and/or other suitable types of fasteners. The supports 82 are connected to form at least one warehouse-receiving zone 54. In the example shown, the supports 82 are arranged to form a plurality of warehouse-receiving zones 54 designed to receive and carry, for example, two modular warehouses 28.

10 However, the load-bearing structure 50 can be constructed in a variety of configurations to carry various numbers of modular warehouses 28 in many types of arrangements and configurations.

In the illustrated embodiment, the struts 82 are further arranged to form the load-bearing structure 50 with a rotating means under the area or aisle 84 providing space for system equipment, such as the portable mixing system 44 as well as comprising the common area 47. For example, the position of the load-bearing structure may be arranged

By means of the warehouse structures 56 in an elevated position allowing the lower feeders 76 to measure the outflow of oilfield material 62 down into the portable blending system 44 when the portable mixing system 44 is positioned and/or rotated in the aisle 84. As shown, upper struts 86 can be used to connect

20 Areas receiving warehouses 54 and to provide overhead loading for a portion of the warehouse consisting of modular structures 56. Overhead supports 86 may be placed at a sufficient height to enable a truck mounted on the portable mixing system 44 to be guided, for example supported, in a rotating under area or aisle 84 to receive oilfield material 62 of the modular warehouses 28. In other embodiments, however, the upper supports 86 may be divided and carried by additional anchor supports to allow separation

The load-bearing structure 50 may also include pivot struts 90 to which pivot connectors can be attached (shown in Figure 6), as described in more detail below. The pivot struts 90 provide a robust area of load-bearing structure 50 into which each repository can be engaged It consists of 28 units initially and then rotates axially

10 Interviewed during the erection of each 28-unit warehouse from lateral to upright operating status. In some applications, the pivot supports 90 are located at a height that matches the corresponding pivot connectors of the modular warehouse 56 when the modular warehouse 28 is installed laterally, for example horizontally, on a suitable road truck 36.

Referring again to Figure 4, the carrier structure 50 may further comprise or be connected

15 with at least one expandable base 92 designed to stabilize the load-bearing structure 50 and modular warehouses 28 when installed in an upright position on the load-bearing structure 50. In the example shown, a plurality of expandable bases 92 are movably connected to a base portion 94 of the structure Load-bearing 50. Extendable bases 92 can be slidably received in the base portion 94 for movement between a contracted position in the base portion 94 and an expanded position, as shown, 20 to provide greater stability to the load-bearing structure 50. Expansion and contraction of expandable bases 92 can be performed

Between collapsed and actuated positions a variety of other types of movable connectors, including hinges and other types of axial connectors, couplings enabling quick connection and detachment of extendable bases 92, and/or other suitable mechanisms. The number and orientation of the 92 extendable bases can also be adjusted according to the variables of a particular application. Extendable bases 92 can be connected to the load-bearing structure 50 to provide

5 Seismic base isolation to the load-bearing structure 50. The extendable bases 92 can include additional slideable or foldable outriggers connected at the side of the extendable base 92 for further stabilization of the load-bearing structure 50.

In Figure 5, an example is shown in which a group of warehouses consisting of:

10 The modules 28 are positioned on two load-bearing structures 50 which are placed side by side. In this example, each individual modular warehouse 28 is transported to the well site 22 by a suitable truck 36. As shown, the suitable truck 36 may include a tractor 98 towing a trailer 100 of a size suitably designed to receive one of the warehouses 28 at Side direction, eg horizontal. In the example shown, the warehouse consisting of 28 units is created so that it spans

15 A truss conveyor 72 vertical conveyor head extends from an enclosed upper portion 80 of the warehouse housing 58 generally along the side of the modular warehouse 28. This allows the modular warehouse 28 to be transported on a conventional gooseneck trailer 92, according to

Explained.

Each truck 36 can be assigned to move laterally placed warehouses 28 in interlocking with zones

20 Correspondingly receiving the warehouses 54 from the load-bearing structure 50. As described above, the load-bearing structure 50 may include pivot supports 90 or other suitable structures located at a suitable height to receive and engage each modular warehouse 28 when it is in the side position on a truck 36. For example, the load-bearing structure 50 and corresponding modular warehouses 28 may use pivot connectors 102 by which

25 The warehouse 28 is selectively positioned with the load-bearing structure 50. The coaxial connectors 102 are positioned

٦٠٣٠

This allows each of the warehouses 28 to be engaged and connected to the load-bearing structure 50 while the warehouse 28 is in a side position on a truck 36. The axial connectors 102 are also designed to maintain the engagement of the modular warehouse 28 with the load-bearing structure 50 while the warehouse is rotated around an axis of Lateral position to operational upright, on

The modular warehouses 28 can be pivoted or moved around pivot connectors 102 from a side position on a truck 36 to an operational position on the load-bearing structure 50 by a variety of mechanisms. For example, the ram 104 (shown in dotted lines) may be used to erect each reservoir 28 between the side position and the upright position. The ram 104 may be a ram

10 Hydraulic or pneumatic mounted on a trailer 100 to operate on the chassis 56 of each modular warehouse 28 to pivot the modular warehouse 28 around pivot connectors 102 until the warehouse 28 is safely moved into its upright position by the warehouses receiving the area 54. The ram 104 is powered by a hydraulic (or pneumatic) system of a truck 36. In other applications, the ram 104 may be designed

15 To pivot the trailer 100 or part of the trailer 100 upward while the modular warehouse 28 remains attached to the pivot portion of the trailer 100. Other techniques may use cranes, pulleys, and/or other mechanisms to pivot each warehouse consisting of 28 units around the axial connection while the 28 unit warehouse is transitioned from lateral position to upright operational orientation.

20 Coaxial connectors 102 are used to facilitate the configuration of the coaxial connection between each modular warehouse 28 and the load-bearing structure 50 and can include a variety of individual or combination connector mechanisms. In general, each axial connector 102 includes an axial rotating member 106 mounted on the stock 28 and a corresponding axial rotating member 108 mounted on the load-bearing structure 50, for example mounted on axial supports 90, as shown in Figure 6. In the example shown

25 Shown in Figures 5 and 6, each warehouse consists of 28 units coaxially interconnected with the structure

Bearing 50 via a pair of pivot connectors 102. For example, each pivot drive member 106 may include a pin 110 rotatably, for example pivotally, a receiver in a corresponding pin receiver 112 forming part of a pivot drive member Views 108. Although the screw 110 is shown connecting to the structure 56 of the warehouse

5 The module consists of 28 and the screw receiver 112 is shown attached to the pivot supports 90 of the load-bearing structure 50, except that the screw 110 and the screw receiver 112 can be reversed. Additionally, the pivot connectors 102 can include a variety of other structures designed to enable selective engagement of the component reservoirs of 28 modules with the load-bearing structure 50 and the controlled movement of the 28-modular warehouses relative to the load-bearing structure 50. Based on

10 Designing the axial connectors 102, a variety of retaining features such as an extension pin anchor 114 may be used to maintain the pivotable connection between the modular warehouse 28 and the load-bearing structure 50 while the modular warehouse 28 is transitioning from the side position to the upright position.

Referring generally to Figure 7, the load-bearing structure 50 may include and/or component repositories

15 Of the 28 modules have other features to detect and/or monitor specific system functions. For example, various sensors 116 may be placed on the load-bearing structure 50 and/or on the modular reservoirs 28 to detect and/or monitor variables related to the delivery of oilfield material 62 for a particular fracturing process. For example, sensors 116 may include load cells installed at areas receiving warehouses 54 to monitor applied loads.

20 Applied by individual 28-modular depots. Loading data can be used to track the amount of oilfield material that remains in an enclosed interior space 60 per 28-modular depot.

In Figures 5, 7, 8 and 9, an operational example is shown to facilitate explanation of how a model of a proppant delivery system might be built at a particular well site. 22

25 The 52 mat system is initially installed at well site 22 as shown in Figure 8.

٦٠٣٠

-٢٠-

The 52 52 mat system can be constructed in a variety of sizes and shapes depending on the medium, size and variables of a particular cracking process. For example, the mat system 52 may include a structural material formed from steel or other suitable structural material, positioned on the pad to distribute the weight of the modular warehouse 28 to the floor, as shown in Figure 8.

5 Once the mat system 52 is in position, at least one load-bearing structure 50 can be assembled and/or placed on the mat system 52, as shown in Figure 9. The load-bearing structure 50 is oriented to receive the modular depots 28 in a desired direction at a location Well 22. In the specific example shown, the load-bearing structure 50 is configured and positioned to receive a plurality of modular reservoirs 28, such as two, three or four modular reservoirs 28.

10 After the load-bearing structure 50 is properly positioned, trucks 36 are used to deliver the modular warehouses 28. In one embodiment, the mat system 52 can be integrated into a base of the load-bearing structure 50.

As shown in Figure 5, for example, an individual modular warehouse 28 can be installed horizontally on the trailer 100 of the truck 36. As described above, 15 each modular warehouse 28 can be designed as a module used Alone or in cooperation

With other depots 28. The modular configuration process along with the design and sizing of modular depots 28 allows individual modular depots 28 to be transported over public highways by truck 36. When the truck 36 and the corresponding modular depot 28 arrive at the well site 22, the truck 36 is used to support the 20-unit warehouse 28 in engagement with a first carrier connection of the load-bearing structure 50 on the mat system 52.

For example, the first load connection of the load-bearing structure may include pivot members 106. The modular warehouse 28 is moved toward the load-bearing structure 50 until the pivot members 106 of the warehouse structure 56 engage with corresponding pivot members 108 of the load-bearing structure 50 to form pivot connectors 102.

It allows the 28-modular warehouse to be safely erected in a controlled manner from the side, for example a horizontal position, to an operational upright position. For example, the 104 hydraulic ram pictured in Figure 5 can be used to erect the 28-unit warehouse into the upright position.

5 36 trucks are used to deliver the next 28 modular warehouses to the load-bearing structure

50 Until the required number of modular reservoirs 28 are placed at the well location 22 as shown in Figure 7. Each of the modular reservoirs 28 is pivoted to the upright position based on the areas receiving the reservoirs 54 from the load-bearing structure 50, according to Shown in Figure 7. After the existing 28 modular warehouses are installed

10 Load-bearing structure 50, the modular stores 28 can be bolted or otherwise secured to the load-bearing structure 50. In some applications, the modular stores 28 can also be bonded together to additionally stabilize the assembly. In the example shown, the load-bearing structure 50 holds the modular bunkers 28 at a height sufficient to receive a portable mixing system 44 in the circulation facility under the area or aisle 84. In this example, the feeding means may be located

15 With modular bunkers 28 for unloading oilfield material into lane 84. Additionally, enclosed conveyor systems 30 can be connected to the inlet hoppers 66 of vertical conveyors 32. At this point, the oil field material 62 can be delivered to the well site 22 and loaded into the modular warehouses 28 via conveyors 30 and anchor conveyors 32.

It should be noted that in some applications, the external conveyor or conveyors 30 include a belt section

20 Exposed allows oilfield material to be unloaded by gravity from appropriately designed gravity feed trucks that are supported on an exposed belt. The belt-fed oilfield material is then conveyed in an enclosed section of conveyor 30 and conveyed along a ramp for release into at least one inlet 66 of the corresponding modular warehouse 28.

The equipment and components of the proppant delivery system 20 can vary greatly depending on the variables of a particular cracking process. The modular depots 28 may be used individually or in groups of modular depots fixedly mounted on the load-bearing structure 50. The modular depots may be installed at a height sufficient to direct the outflowing oilfield material

5 Through an outflow feeder located at the bottom of the inner enclosure and in the passage 84. In other applications, the feeder may be located to direct the outflow of oilfield material from a higher compartment within the modular warehouse 28. In some applications, it may include The warehouse consists of 28 units on an enclosed internal space divided into a group of compartments to hold different types of oil field material that can be selectively fed into the system.

10 Homogenizer 44 for mixing into a desired mixture which is then pumped downhole into the wellbore.

Additional image: Conveyors with various belts or other types of conveyors can be included to deliver oil field material from the unloading area to the existing, 28-unit warehouses. 28-unit warehouses can also include a variety of dock conveyors to lift the oil field material to the unloading area. Overhead warehouses consisting of 28 units. Allows the processing of various equipment from existing warehouses

15 Of the 28 units storing a large amount of oil field material that can be easily supplied for use in the fracking process. The existing 28-modular warehouse facility also provides efficient use of well site space. In addition to space efficiency, the step system for storing and delivering oilfield material provides an extremely clean well site free of dust production. However, depending on the specifics of a particular cracking operation, various numbers and equipment of 28-unit warehouses may be used.

20 Conveyors 30 and 32, mixing systems 44, and other wellsite equipment.

The load-bearing structure 50 and mat system 52 can also be configured in various forms and configurations based on the required fracture process variables. For example, the load-bearing structure 50 may be constructed from many types of bracing structures, combinations of supports and other structural components, and/or structural arms or other devices to hold modular warehouses 28. In some applications, the load-bearing structure 50 may be constructed on A-frame body or A-frame with the top cut off. Load-bearing structure can be created

50 Also as a single monolithic continuous load-bearing structure or as a group of sub-load-bearing structures that can be separated to accommodate the separation of individual modular warehouses 28 and/or the separation of groups of modular warehouses 28. Likewise, the mat system 52 can be constructed in a variety of materials and in A variety of bodies based on the variables of the cracking process and on the characteristics

5 Characteristics of corresponding equipment, for example 28 modular bunkers, 44 mixing systems, and other equipment facilitate hydraulic fracturing.

Mobile 200. Once the truck 201 is detached, the curved link section 206 can be manipulated so that it is extended on the ground and generally co-level with the load base 202. In this configuration, the curved link section 206 can form a ramp to assist the operator in positioning Mixing system 44 within the passage 230 as shown in Figure 1. The part may be supplied on

5 A curved connection shape 206 with a first section 320 and a second section 322. The first section 320 extends from the first end 220 of the load base 202. The first section 320 includes a first end 324 and a second end 326. The first end 324 of the first section 320 is movably connected to the load base 208, for example Using a combination of hinges, blanks, screws, or other types of connectors that can be fixed in more than one position. The second section 322 is movably connected to the second terminal

10 326 for the first section 320. For example, the first section 320 may be a link of four

Columns can be installed in an elevated position to form the curved connection, or in a lower position to form the slope.

The mobile carrier structure 200 is shown in Figure 12 in operational form. In the operational configuration depicted in Figure 12, the modular warehouses 28 can be loaded onto the mobile carrier structure 200, as shown, for example, in Figures 1 and 13-17, and the

15 Mixing system 44 inside lane 230.

An example in which a modular reservoir 28 is placed in position on the mobile load-bearing structure 200 is illustrated in Figures 13-17. In this example, each individual modular reservoir 28 is transported to the well site 22 by truck 36. as shown. , the truck 36 may include the tractor 98 to tow the trailer 100 of a size suitably designed to receive a

20 Warehouses 28 in a sideways direction, eg horizontal.

The truck 36 can be positioned to move the modular side-mounted warehouse 28 into gear with corresponding zones receiving warehouses 232 from the mobile load-bearing structure 200. Additional guide rails can be designed in the first and second extendable bases 240 and 242 to assist in aligning the warehouse trailer to the zone receiving the warehouse 232 In addition to the above to help with alignment

However, the first and second extendable bases 240 and 242 may also serve as a reference anchorage for the warehouse trailer.

As described above, the mobile carrier structure 200 may include a second connection 302 or other suitable structures located at a suitable height to receive and engage each warehouse consisting of

5 Modules 28 when in the side position on the truck 36. For example, the mobile rack 200 and corresponding modular bunkers 28 may utilize first and second connectors 310 and 312 by which the modular rack 28 can selectively interface with the mobile rack 200. The first and second connectors 310 and 312 can be pivotal connectors that are positioned to allow each 28-modular warehouse 10 to be interlocked and connected to the mobile load-bearing structure 200 while the 28-modular warehouse 28 is in a lateral position.

On the truck 36. The first and second connectors 310 and 312 are further designed to keep the modular warehouse 28 engaged with the mobile load-bearing structure 200 as the modular warehouse 28 is rotated axially from a sideways position to an upright operational orientation, e.g., ARC.

The 28 modular warehouses can be rotated axially or moved around the first connectors

15 The second 310 and 312 move from the side position on the truck 36 to the operational, upright position on the load-bearing structure 204 of the mobile load-bearing structure 200 with a variety of mechanisms. For example, the ram 104 may be used to erect each 28-modular warehouse between the side position and the upright position. The tamper 104 may be a hydraulic ram or pneumatic ram placed on a trailer 100 to work on the structure 56 of each modular warehouse.

20 28 To rotate the modular warehouse 28 around the first and second connectors 310 and 312

So that the modular warehouse 28 can be safely placed upright by the warehouse receiving area 232. The ram 104 can be designed to disconnect a hydraulic (or pneumatic) system on the truck 36. In other applications, the ram 104 can be designed to pivot the trailer 100 or Part of the trailer 100 points upward while the 28-unit warehouse remains attached to the part

Another way to pivot each 28-modular warehouse around the first and second connectors 310 and 312 as the 28-modular warehouse is moved from the lateral position to the existing operational direction.

The first and second connectors 310 and 312 are illustrated in more detail in Figures 14 and 15. The first and second connectors 310 and 312 are used to facilitate configuration of the connection between each component repository

5 of the 28 modules and the mobile load-bearing structure 200 and may comprise a variety of individual or combination conductor mechanisms. In general, each of the first and second connectors 310 and 312 are designed to permit controlled movement of the modular warehouse 28 relative to the mobile load-bearing structure 200. The first and second connectors 310 and 312 may include a warehouse-mounted axial rotating member 28 and a corresponding axial rotating member mounted On the mobile carrier structure 200, for example

10 The example is mounted on supports 330, as shown in Figures 14 and 15. In the example shown in Figures 14 and 15, each modular warehouse 28 is pivotally engaged with the mobile load-bearing structure 200 by a pair of pivot members. For example, each axial drive member may include a screw in a rotatable manner, such as axially, received in a corresponding pin receiver of the pivot member.

15 corresponding pivot member. Although the screw can be attached to the structure 56 of the modular warehouse 28 and the screw receiver can be connected to pivot supports 330 of the load-bearing structure 50, the screw and the screw receiver can be reversed. Additionally, the first and second connectors 310 and 312 can include a variety of other structures designed to enable selective interconnection of modular warehouses 28 with the mobile carrier structure 200 and controlled movement

20 Therein for 28-modular warehouses for the mobile load-bearing structure 200. Depending on the design of the first and second connectors 310 and 312, a variety of retaining features such as an extension pin anchor may be used to maintain a pivotable connection between the 28-modular warehouse and the mobile load-bearing structure 200 during transport For the 28 modular warehouse from side to upright position.

The mobile load-bearing structure 200 may also be equipped with other types of equipment to facilitate the handling of oilfield material and/or mixing of oilfield material to form slurry as described above. For example, the mobile load-bearing structure 200 can be equipped with a power generation system 340 that is carried by wheels 208. In this embodiment, the power generation system 340 can be used to generate electrical power that can be supplied to

5 Conveyors 30 and 32 as well as other equipment at the proppant delivery system 20. The mobile load-bearing structure 200 may also be equipped with dry feed additives, power sources, controls and means of control, and a sled to carry a mixing system integrated into the load base 202. In addition to the above , the mobile load-bearing structure 200 can be equipped with weather protection to protect against harsh environmental conditions. In addition, the mobile carrier 200 can be equipped with various sensors 116

10 Placed on the structural structure 204 and/or on the modular reservoirs 28 to detect and/or monitor variables relevant to the delivery of oil field material 62 to a particular fracturing process. For example, sensors 116 may include four load cells in each warehouse receiving area 232 and may form part of connectors 306, 308, 310 and 312 to monitor loads placed by individual modular warehouses 28. Load data can be used to track the amount of

15 Oil field material that remains in an enclosed internal space of 60 per warehouse consisting of 28 thousand units for inventory management purposes.

A horizontal view of the mobile load-bearing structure 200 is shown in Figure 18. The conductors 306, 308, 310 and 312 may be arranged in a truncated triangle 350, such as a semi-recessed one to improve the stability of the mobile modular warehouse 28 within the area receiving the warehouse.

20 232. In addition, to help carry the warehouse consisting of 28 units, space

The combined horizontality of the load base 202, a first extendable base 240 and a second extendable base 242 is much greater than the horizontal area occupied by one of the modular warehouses 28 when mounted on the mobile load-bearing structure 200. For example, a first horizontal area 352 occupied by one is shown Of the 28-unit warehouses when placed in the arc orientation shown in

25 Figure 18. From what we can see, the load base occupies 202, and the first extendable base 240

The second base is expandable 242 and a common second horizontal area is at least one and a half times the size of the first horizontal area 352 and can be eight or ten times the size of the first horizontal area 352 in size.

Shown in Figure 19 is a second embodiment of a portable mobile structure 400, which is similar in structure

5 The function is the same as the mobile portable structure 200, except that the mobile portable structure 400 includes an integrated mixing system 410 . The integrated mixing system can be transported with other components of the mobile portable structure 400 and is provided on skids or tracks to be transported to the load-bearing base 412 of the mobile portable structure 400.
