Abstract
Techniques for determining subsurface conditions in a multi-well system may include detecting, at time t1, a tube wave at a first well system of the multi-well system. The techniques may further include detecting, at time t2, the tube wave at a second well system of the multi-well system. The techniques may further include determining a time differential td between t1 and t2. The techniques may further include determining, based at least in part on td, that the first well system and the second well system are in fluid communication via a formation.
Claims20
A method for determining subsurface conditions in a multi-well system, the method comprising:
- detecting, at time t1, a tube wave at a first well system of the multi-well system;
- detecting, at time t2, the tube wave at a second well system of the multi-well system;
- determining a time differential td between t1 and t2;
- and
- determining, based at least in part on td, that the first well system and the second well system are in fluid communication via a formation.
A multi-well system comprising:
- a computing system comprising:
- one or more processors;
- and
- one or more non-transitory computer-readable mediums including instructions which, when executed by the one or more processors, cause the one or more processors to determine subsurface conditions in the multi-well system, the instructions including:
- instructions to detect a tube wave at a first well system of the multi-well system, wherein a time of detection is t1;
- instructions to detect the tube wave at a second well system of the multi-well system wherein a time of detection is t2;
- instructions to determine a time differential td between t1 and t2;
- and
- instructions to determine, based at least in part on td, that the first well system and the second well system are in fluid communication via a formation.
One or more non-transitory computer-readable mediums including instructions which, when executed by a processor, cause the processor to determine subsurface conditions in a multi-well system, the instructions comprising:
- instructions to detect a first tube wave at a first well system of the multi-well system, wherein a time of detection is t1;
- instructions to detect the first tube wave at a second well system of the multi-well system, wherein a time of detection is t2;
- instructions to determine a first time differential td1 between t1 and t2;
- and
- instructions to determine, based at least in part on td1, that the first well system and the second well system are in fluid communication via a formation.
