System and method for well control
Systems and methods are provided for supervising the control of wells in a grouping of wells, or “well pads,” in a subterranean hydrocarbon reservoir so as to coordinate operation of the well pad. By coordinating operation of the well pad, hydrocarbon production for the well pad can be optimized. An exemplary method includes the steps of generating a plurality of requests to control individual wells of the well grouping, queuing the requests, and authorizing the requests based on one or more criteria associated with the well grouping so as to coordinate operation of the well grouping.
1. A well control system for a subterranean hydrocarbon reservoir, the system comprising:
a plurality of well control systems, each of the well control systems being associated with an individual well of a grouping of wells from a well pad in fluid communication with the subterranean reservoir;
a plurality of well controllers associated with each of the individual well control systems that control operation of the individual well control systems based on one or more criteria associated with the individual well; and
a supervisor controller in communication with each of the well controllers for coordinating operation of each of the well control systems by allowing or postponing operation of individual wells within the grouping of wells from the well pad until one or more criteria associated with the well pad is satisfied.
2. The system according to claim 1 , wherein:
each of the well control systems comprise a well plunger lift mechanism;
each of the well controllers comprise a well plunger lift controller for controlling operation of a corresponding well plunger lift mechanism; and
the supervisor controller comprises a supervisor plunger lift controller in communication with each of the well plunger lift controllers.
3. The system according to claim 1 , wherein the supervisor controller comprises a computer processor for executing a computer program, the computer program comprising:
a first computer program code for generating a plurality of requests to control the individual wells of the grouping of wells from the well pad;
a second computer program code for queuing the requests such that that the requests are ordered according to each individual well satisfying one or more criteria associated with the individual well; and
a third computer code for authorizing the requests based on the one or more criteria associated with the well pad so as to coordinate operation of the individual wells within the grouping of wells from the well p.
4. The system according to claim 1 , wherein the one or more criteria associated with the well pad relate to plunger lift parameters of the well pad.
5. The system according to claim 1 , wherein the one or more criteria associated with the well pad relate to power consumption parameters of the well pad.
6. The system according to claim 1 , wherein the one or more criteria associated with the well pad relate to equipment usage parameters of the well pad.
7. The system according to claim 1 , wherein the one or more criteria associated with the well pad relate to safety requirements of the well pad.
8. The system according to claim 1 , wherein the one or more criteria associated with the well pad include at least one of well pad pressure, well pad flow rate, plunger arrival states of the individual wells within the grouping of wells, a number of open valves of the individual wells within the grouping of wells, or a number of closed valves of the individual wells within the grouping of wells.
9. A computer-implemented method of operating a subterranean hydrocarbon reservoir, the method comprising:
generating a plurality of requests to control individual wells of a well grouping from a well pad;
queuing the requests such that the requests are ordered according to when each individual well satisfies one or more individual well criteria; and
authorizing the requests based on one or more criteria associated with the well pad so as to coordinate operation of the individual wells within the well grouping.
10. The method according to claim 9 , wherein the one or more criteria associated with the well pad relate to plunger lift parameters of the well pad.
11. The method according to claim 9 , wherein the one or more criteria associated with the well pad relate to power consumption parameters of the well pad.
12. The method according to claim 9 , wherein the one or more criteria associated with the well pad relate to equipment usage parameters of the well pad.
13. The method according to claim 9 , wherein the one or more criteria associated with the well pad relate to safety requirements of the well pad.
14. The method according to claim 9 , wherein the one or more criteria associated with the well pad include at least one of well pad pressure, well pad flow rate, plunger arrival states of the individual wells within the grouping of wells, a number of open valves of the individual wells within the grouping of wells, or a number of closed valves of the individual wells within the grouping of wells.
15. An article of manufacture, comprising computer usable media having a computer readable program code embodied therein, the computer readable program code adapted to be executed to implement a method of conducting activities related to the operation of a hydrocarbon reservoir, the method comprising:
generating a plurality of requests to control individual wells of a well grouping from a well pad;
queuing the requests such that the requests are ordered according to when each individual well satisfies one or more individual well criteria; and
authorizing the requests based on one or more criteria associated with the well pad so as to coordinate operation of the individual wells within the well grouping.
16. The article of manufacture according to claim 15 , wherein the one or more criteria associated with the well pad relate to plunger lift parameters of the well pad.
17. The article of manufacture according to claim 15 , wherein the one or more criteria associated with the well pad relate to power consumption parameters of the well pad.
18. The article of manufacture according to claim 15 , wherein the one or more criteria associated with the well pad relate to equipment usage parameters of the well pad.
19. The article of manufacture according to claim 15 , wherein the one or more criteria associated with the well pad relate to safety requirements of the well pad.
20. The article of manufacture according to claim 15 , wherein the one or more criteria associated with the well pad include at least one of well pad pressure, well pad flow rate, plunger arrival states of the individual wells within the grouping of wells, a number of open valves of the individual wells within the grouping of wells, or a number of closed valves of the individual wells within the grouping of wells.
