Abstract

Systems and methods presented herein enable coordinated pumping operations. An example system may include a treatment fluid system configured to pump a treatment fluid into a wellbore, a pump-down system configured to pump a pump-down fluid into the wellbore to convey a perforating tool, a fluid valve system configured to selectively fluidly connect and disconnect the treatment fluid system and the pump-down system to and from the wellbore, and a controller communicatively connected to the treatment fluid system, the pump-down system, and the fluid valve system. The controller may be configured to monitor operational status of the treatment fluid system, the pump-down system, and the fluid valve system, and control operations of the treatment fluid system, the pump-down system, and the fluid valve system based at least in part on the operational status of the treatment fluid system, the pump-down system, and the fluid valve system.

First claim

The invention claimed is:

1. A system, comprising:
a fluid valve system configured to selectively fluidly connect, disconnect, and distribute a fluid from one or more surface fluid delivery systems to and from a plurality of wellbores extending into a subterranean formation from a surface of an oil and gas wellsite; and
a controller comprising at least one processor and at least one memory storing processor-executable instructions, wherein the controller is communicatively connected to the fluid valve system and the one or more surface fluid delivery systems, and wherein the processor-executable instructions, when executed by the at least one processor, cause the controller to:
monitor operational statuses of the fluid valve system and the one or more surface fluid delivery systems; and
control operations of the fluid valve system based at least in part on the operational statuses of the fluid valve system and the one or more surface fluid delivery systems.

2. The system of claim 1 , wherein the fluid valve system comprises:
a first fluid control valve fluidly connected between a first surface fluid delivery system of the one or more surface fluid delivery systems and the wellbore, wherein the first fluid control valve is configured to selectively fluidly connect and disconnect the first surface fluid delivery system to and from the wellbore, and wherein the first fluid control valve is connected to a wellhead associated with the wellbore; and
a second fluid control valve fluidly connected between a second surface fluid delivery system of the one or more surface fluid delivery systems and the wellbore, wherein the second fluid control valve is configured to selectively fluidly connect and disconnect the second surface fluid delivery system to and from the wellbore, and wherein the second fluid control valve is connected to the wellhead.

3. The system of claim 2 , wherein the fluid valve system comprises one or more interlock valves configured to isolate the first and second surface fluid delivery systems from each other when swapping between the first and second surface fluid delivery systems being fluidly connected and disconnected to and from the wellbore.

4. The system of claim 1 , wherein the processor-executable instructions, when executed by the at least one processor, cause the controller to operate the fluid valve system to alternatingly connect and disconnect a treatment fluid system and a pump-down system of the one or more surface fluid delivery systems to and from the wellbore.

5. The system of claim 4 , wherein the processor-executable instructions, when executed by the at least one processor, cause the controller to operate the fluid valve system to:
open a first valve of the fluid valve system to fluidly connect the treatment fluid system to the wellbore during well treatment operations performed by the treatment fluid system;
close a second valve of the fluid valve system to fluidly disconnect the pump-down system from the wellbore during the well treatment operations performed by the treatment fluid system;
open the second valve of the fluid valve system to fluidly connect the pump-down system to the wellbore during pump-down operations performed by the pump-down system; and
close the first valve of the fluid valve system to fluidly disconnect the treatment fluid system from the wellbore during the pump-down operations performed by the pump-down system.

6. The system of claim 4 , wherein the processor-executable instructions, when executed by the at least one processor, cause the controller to:
after treatment fluid is pumped into the wellbore from the treatment fluid system:
operate the fluid valve system to fluidly disconnect the treatment fluid system from the wellbore; and
operate the fluid valve system to fluidly connect the pump-down system to the wellbore; and

after pump-down fluid is pumped into the wellbore from the pump-down system and a perforating tool is retrieved from the wellbore:
operate the fluid valve system to fluidly disconnect the pump-down system from the wellbore; and
operate the fluid valve system to fluidly connect the treatment fluid system to the wellbore.

7. The system of claim 1 , and wherein the processor-executable instructions, when executed by the at least one processor, cause the controller to:
monitor operational statuses of the fluid valve system and the one or more surface fluid delivery systems with respect to each wellbore; and
control operations of the fluid valve system with respect to each wellbore based at least in part on the operational statuses of the fluid valve system and the one or more surface fluid delivery systems, thereby facilitating distributed injection of a treatment fluid from the surface fluid delivery systems into the plurality of wellbores.

8. The system of claim 1 , wherein the operational statuses of the fluid valve system comprise valve positions of valves of the fluid valve system that are monitored by the controller in substantially real time.

9. The system of claim 1 , wherein the controller is configured to remotely control the operations of the fluid valve system.

10. A method, comprising:
monitoring, using a controller, operational statuses of a fluid valve system and one or more surface fluid delivery systems; and
controlling, using the controller, operations of the fluid valve system to selectively fluidly connect, disconnect, and distribute fluid from the one or more surface fluid delivery systems to and from a plurality of wellbores extending into a subterranean formation from a surface of an oil and gas wellsite based at least in part on the operational statuses of the fluid valve system and the one or more surface fluid delivery systems.

11. The method of claim 10 , comprising:
operating a first fluid control valve of the fluid valve system to selectively fluidly connect and disconnect a first surface fluid delivery system of the one or more surface fluid delivery systems to and from the wellbore, wherein the first fluid control valve is connected to a wellhead associated with the wellbore; and
operating a second fluid control valve of the fluid valve system to selectively fluidly connect and disconnect a first surface fluid delivery system of the one or more surface fluid delivery systems to and from the wellbore, wherein the second fluid control valve is connected to the wellhead.

12. The method of claim 10 , comprising operating, using the controller, the fluid valve system to alternatingly connect and disconnect a treatment fluid system and a pump-down system of the one or more surface fluid delivery systems to and from the wellbore.

13. The method of claim 12 , comprising:
opening, using the controller, a first valve of the fluid valve system to fluidly connect the treatment fluid system to the wellbore during well treatment operations performed by the treatment fluid system;
closing, using the controller, a second valve of the fluid valve system to fluidly disconnect the pump-down system from the wellbore during the well treatment operations performed by the treatment fluid system;
opening, using the controller, the second valve of the fluid valve system to fluidly connect the pump-down system to the wellbore during pump-down operations performed by the pump-down system; and
closing, using the controller, the first valve of the fluid valve system to fluidly disconnect the treatment fluid system from the wellbore during the pump-down operations performed by the pump-down system.
