RELATED APPLICATIONS

The present application claims priority to U.S. Provisional Patent Application No. 63/347,856, filed Jun. 1, 2022, the entire content of which is incorporated herein by reference.

TECHNICAL FIELD

Embodiments of the technology relate generally to partitioning high pressure pumps at a well site.

BACKGROUND

High pressure pumps are commonly used at a well site in connection with the production of hydrocarbons. The high pressure pumps are used to inject a variety of fluids into an oil or gas well during certain well operations. One such operation is hydraulic fracturing, which is a process that involves injecting fluids into a well at high pressure to fracture a formation. The injected fluids include a slurry containing particles that prop open fractures in the formation to improve the flow of hydrocarbons from the formation into the well. Hydraulic fracturing typically uses high pressure pumps to obtain the required high pressures for injecting the fluids into the well. A well site often includes a well pad with multiple wellheads. Numerous high pressure pumps at the well site are used to inject the high pressure fluids into the wells. The high pressure pumps are typically connected to a fracturing manifold that directs the high pressure fracturing fluids to a zipper manifold which in turn directs the fluids to the wellheads at the well pad.
A significant limitation to improving the operational performance of a well site employing hydraulic fracturing is the need for regular maintenance on the high pressure pumps. The area around the high pressure pumps is referred to as the red zone because the high pressures generated by the pumps create risks of leaks and equipment failures that can be dangerous to workers. For the safety of workers, maintenance typically requires that the high pressure pumps are turned off and depressurized before the workers can enter the red zone to perform maintenance. However, turning off and depressurizing the high pressure pumps requires shutting down the equipment at the well site for significant periods of time, resulting in substantial disruption of the operations of the well site as well as added costs.
Accordingly, improved approaches to performing maintenance on the high pressure pumps use in hydraulic fracturing would improve the operations of the well site and reduce costs.

DETAILED DESCRIPTION OF EXAMPLE EMBODIMENTS

The example embodiments discussed herein are directed to apparatus and methods for partitioning high pressure pumps at a well site to improve operations of the well site. Because slurry pumps typically require frequent maintenance while brine pumps do not, a brine pump area and a slurry pump area can be separated by a split stream barrier. Additionally, the slurry pump area can sub-divided with slurry barriers to separate one or more slurry pumps from other slurry pumps. The system of barriers allows one or more slurry pumps to be deactivated for maintenance while other slurry pumps and the brine pumps continue to operate. Isolating the high pressure slurry pumps for maintenance improves the safety of the well site for workers performing maintenance on the slurry pumps. Additionally, the system of barriers permits operations of the well site to continue while maintenance is performed on a selected slurry pump. Accordingly, the well site can operate more efficiently.
In the following paragraphs, particular embodiments will be described in further detail by way of example with reference to the drawings. In the description, well-known components, methods, and/or processing techniques are omitted or briefly described. Furthermore, reference to various feature(s) of the embodiments is not to suggest that all embodiments must include the referenced feature(s).
FIGS. 1 and 2 illustrate prior art approaches to operating a well site. FIG. 1 illustrates a typical well site 100 as known in the prior art. Well sites can often include multiple wells as illustrated by well 1, well 2, well 3, and well 4 located on well pad 105. Well site 100 includes tanks 150, 152, and 154 containing fracturing fluid that is injected at the wellhead of each well. The fracturing fluid can include brine as well as other fluids that assist with the hydraulic fracturing operation. A blender 140 can be used to mix sand or other proppant into one or more streams of the fracturing fluid. Flow lines connect the tanks 150, 152, and 154 and the blender 140 to a fracturing manifold 115. The fracturing manifold 115 feeds the various fracturing fluid streams to the high pressure pumps 120, 122, 124, 126, 128, and 130 where the pressure of the fluid streams is increased before they are injected into the wells. The fracturing manifold 115 directs the high pressure fracturing fluids to a zipper manifold 110 that is coupled to the wellheads of each of wells 1, 2, 3, and 4. A hydraulic fracturing operation performed on a single well often requires multiple high pressure fluid streams from multiple high pressure pumps.
As referenced previously, the high pressures generated by the pumps increase the probability of equipment leaking or failing, thereby increasing the risks for workers in the areas around the high pressure pumps 120, 122, 124, 126, 128, and 130. Accordingly, it is common to refer to the areas around the high pressure pumps as red zones. Given the increased risks in the red zones, if maintenance is needed on a single pump, it is common to shut down and depressurize all nearby pumps so that the maintenance can be performed. However, shutting down all nearby pumps disrupts the operation of the well site 100.
Separately, FIG. 2 illustrates an example of a prior art wellhead barrier that can be installed at a well pad of a well site 200. As shown in FIG. 2 , wellhead barrier 215 is installed between wellhead 205 and wellhead 210. The wellhead barrier 215 provides protection to workers performing work on one of the wells so that the other well can remain pressurized and operating.
Referring now to FIGS. 3-10 , example embodiments for improved barrier systems for well sites will be described in accordance with the example embodiments of this disclosure. Referring to FIG. 3 , a well site 300 in accordance with the embodiments of this disclosure is illustrated. Well site 300 includes a well pad 305 with wells 1, 2, 3, 4, 5, 6, and 7. Well site 300 is arranged for hydraulic fracturing operations. The well site includes a boost pump 342 that pumps hydraulic fracturing fluid from tanks 350 for use in the wells at the well pad 305. A blender 340 can mix sand (and/or another proppant) from sand storage area 355 into certain of the streams of hydraulic fracturing fluid.
Well site 300 includes two strategies for improving the operation of the well site. First, the high pressure pumps are organized into a split stream arrangement where they are separated into a brine pump area 370 and a slurry pump area 380. The brine pumps will pump brine solution that does not include a proppant. In contrast, the slurry pumps will pump a slurry solution that includes a proppant. The existence of a proppant in the fluid stream often causes fouling of valves and other components of the pumps, resulting in the need for more frequent maintenance of the pumps. The advantage of the split stream arrangement is that the pumps handling the fluid streams with proppant, which will require more frequent maintenance, are separated into a slurry pump area. In contrast, the pumps handling a brine solution that does not include a proppant, and therefore require less frequent maintenance, are organized into a brine pump area.
FIG. 3 illustrates a barrier system 360 that separates a brine pump area 370 from two slurry pump areas 380 and 381. While the barrier system 360 is illustrated in general form in FIG. 3 , examples of specific implements of the barrier system are shown in greater detail in FIGS. 5-10 . Specifically, the barrier system can include a split stream barrier that separates the brine pump area from the slurry pump area(s). The barrier system can also include slurry barriers located between individual slurry pumps or groups of slurry pumps. Given the more frequent maintenance of the slurry pumps, the slurry barriers are beneficial for isolating individual slurry pumps or groups of slurry pumps. In contrast, there is not the same level of need for individual barriers between brine pumps in the brine pump area because the brine pumps require relatively infrequent maintenance. The barrier system allows individual slurry pumps or groups of slurry pumps to be turned off and depressurized for performing maintenance while the remaining slurry pumps and the brine pumps can continue to operate. The barrier system will protect workers in the red zone area around the pump(s) receiving maintenance from the high pressure conditions of surrounding slurry pumps and brine pumps that are continuing to operate.
As illustrated in FIG. 3 , a fracturing manifold 315 receives slurry fluid streams containing proppant from the blender 340 and supplies those slurry fluid streams to the slurry pumps in slurry pump areas 380 and 381. Similarly, the fracturing manifold 315 receives brine fluid streams (without a proppant) from the boost pump 342 and supplies those brine fluid streams to the brine pumps in the brine pump area 370. The fracturing manifold 315 then receives the pressurized slurry fluid streams and brine fluid streams from the respective pumps and supplies those pressurized streams to the zipper manifold 310 for delivery to the wellhead of each well
Referring now to FIG. 4 , and example method 400 is illustrated for operating a well site in accordance with the example embodiments of the present disclosure. It should be understood that method 400 is intended to be a representative example and that in alternate embodiments certain operations of method 400 can be combined, performed in parallel, or omitted. Additionally, other operations can be added to method 400.
In operation 405, brine pumps are positioned at the well site in the brine pump area and slurry pumps are positioned at the well site in the slurry pump area. The brine pumps and slurry pumps are typically located on trailers that are transported to and positioned at the well site. In operation 410, one or more split stream barriers are installed between the brine pump area and the slurry pump area. In operation 415, one or more slurry barriers are installed between the slurry pumps. In some cases, slurry barriers can be installed between each slurry pump. In other cases, slurry barriers can be installed between subgroups of slurry pumps. Once the barrier system is installed, the hydraulic fracturing operations can proceed with a split stream approach on the wells in operation 420.
Given the negative affects of proppant on the slurry pumps, slurry pumps can be identified for maintenance when needed. In operation 425, a slurry pump is selected for maintenance. Alternatively, a subgroup of slurry pumps can be selected for maintenance. In operation 430, the slurry pump selected for maintenance is turned off and depressurized. Each slurry pump can be equipped with an actuator that is remotely controlled and that can control powering off/on and depressurizing/ pressurizing the slurry pump. The actuator can be remotely controlled by radio signals or a length of cable that allows a worker to control the pump without being in proximity to the pump. With the selected slurry pump turned off and depressurized, it is now safe for workers to be in the red zone surrounding the slurry pump in order to perform maintenance as indicated in operation 435. The protection provided by the barrier system allows adjacent slurry pumps and brine pumps to continue operating at high pressures while the workers perform maintenance on the selected slurry pump.
After the maintenance is complete, the workers can move away from the selected slurry pump and can use the remotely controlled actuator to prime and restart the selected slurry pump in operation 440. As indicated in operation 445, method 400 can return to operation 420 where the hydraulic fracturing operations can proceed at the well site until maintenance is required on another slurry pump.
While method 400 of FIG. 4 describes operations for performing maintenance on a slurry pump, it should be understood that the method can be adapted for performing maintenance on a group of slurry pumps. Additionally, method 400 also can be adapted for performing maintenance on a brine pump or a group of brine pumps. As another modification of method 400, it should be understood that slurry pumps and brine pumps are not required to be in the off state for priming such that in some embodiments the slurry and brine pumps can be remotely primed while they are pumping.
Turning to FIGS. 5-10 , example implementations of barrier systems are illustrated. It should be appreciated that other variations on the configurations of the barrier systems of FIGS. 5-10 are encompassed by this disclosure. Additionally, the barriers can take a variety of shape and form. In certain examples, the barrier walls can be walls or flexible curtains of high strength material such as composites, metals, alloys, or polymers such as Kevlar. The dimensions of the barrier walls should be sufficient to protect workers from the high pressures of adjacent pumps. The thickness of the barrier walls should be relatively thin, such as within the range of 0.25 inches to 6 inches, so that they can easily fit between slurry pumps at a well site. The height of the barrier walls should be at least 6 feet and preferably in the range of 8 feet to 20 feet. The barrier walls typically will have one or more openings, flaps, or ports that allow flow lines to pass through the barrier wall, such as the lines that pass between the pumps and the fracturing manifold. Referring to FIG. 5 , an example well site 500 is illustrated. Well site 500 has been divided into a brine pump area 570, containing brine pumps, and a slurry pump area 580, containing slurry pumps. A split stream barrier 561 separates the brine pump area 570 from the slurry pump area 580. The slurry pump area 580 is subdivided into areas B, C, D, and E. One or more slurry pumps can be located in each of areas B, C, D, and E. Slurry barriers 563 are placed between each of areas B, C, D, and E. Accordingly, area C, for example, is separated from adjacent areas B and D by slurry barriers and is separated from the adjacent brine pump area 570 by split stream barrier 561. As such, the barrier system provides protection to workers performing maintenance on a slurry pump in area C while the brine pumps in the brine pump area 570 and the slurry pumps in slurry pump areas B, D, and E continue to operate at high pressures.
FIG. 6 illustrates another example of a barrier system arranged at well site 600. At well site 600, a split stream barrier 661 is positioned between a brine pump area 670 and a slurry pump area 680. Additionally, the slurry pump area is subdivided into areas B, C, D, and E, each of which can contain one or more slurry pumps. Slurry barriers 663 are placed between each of subdivided areas B, C, D, and E. Area B, for example, is separated from adjacent slurry pumps in areas C, D, and E by slurry barriers 663 and is separated from the adjacent brine pump area 670 by split stream barrier 661. Accordingly, workers can perform maintenance on a slurry pump in area B while being protected by the barrier system from pumps in slurry pump areas C, D, and E and pumps in brine pump area 670 that continue to operate at high pressures.
FIG. 7 illustrates another configuration of a well site 700. In well site 700, brine pump area 770 is separated from the slurry pump area 780 by a split stream barrier 761. The slurry pumps in the slurry pump area are separated into areas C and D by a slurry barrier 763. Additionally, the brine pump area 770 is subdivided into areas A and B by a brine barrier 765. The brine barrier 765 can be similar to the other types of barriers previously described and can be used to isolate individual brine pumps or subgroups of brine pumps for purposes of performing maintenance on the brine pumps. The brine barrier 765 can allow maintenance to be performed on one or more brine pumps in area A while the brine pumps in area B continue to operate.
FIG. 8 illustrates yet another configuration of a well site 800. The configuration of well site 800 is similar to that of well site 700 in that brine pump area 870 is separated from the slurry pump area 880 by a split stream barrier 861. The slurry pumps in the slurry pump area are separated into areas C, D, E and F by slurry barriers 863. Additionally, the brine pump area 770 is subdivided into areas A and B by a brine barrier 865, which is similar to the brine barrier 765 of FIG. 7 . Similar to the brine barrier of FIG. 7 , the brine barrier 865 can be used to isolate individual brine pumps or subgroups of brine pumps for purposes of performing maintenance on the brine pumps.
FIG. 9 illustrates yet another configuration of a well site 900. In well site 900, brine pump area 970 is separated from slurry pump areas 980 and 981 by split stream barriers 961. The slurry pumps in the slurry pump areas are separated into areas B, C, D and E by a slurry barriers 963 and 964.
FIG. 10 illustrates yet another configuration of a well site 1000. In well site 1000, brine pump area 1070 is separated from slurry pump areas 1080 by split stream barriers 1061. The slurry pumps in the slurry pump areas are separated into areas B, C, D and E by a slurry barriers 1063.
