Abstract
Wellbore systems include one or more sensing devices configured to sense physical parameters before, during, and/or after fluid injection procedures are performed to inject fluid into a subterranean formation. Seismic vibrations may be induced into the subterranean formation and detected at the injection wellbore or in a remote monitoring wellbore as part of monitoring and evaluation of the fluid injection operations. The one or more sensing devices may also be configured to monitor well production and/or formation conditions in and around a single wellbore and/or in multiple wellbore systems.
Claims14
A system comprising:
- a fluid injection tubing positioned downhole within a wellbore, wherein at least some portion of the fluid injection tubing is positioned within a casing, the casing surrounded by an annulus extending between an outer surface of the casing and an exposed portion of a formation within the wellbore;
- and
- one or more first sensing devices positioned along the outer surface of the casing or between the casing and the formation, wherein the one or more first sensing devices are communicatively coupled to a single communication line, and wherein at least one of the one or more first sensing devices is configured to sense seismic vibrations transmitted into and passing through the formation and to provide one or more output signals representative of the sensed seismic vibrations.
A method comprising:
- generating and transmitting seismic vibrations into a subterranean formation;
- performing, using a wellbore system including a fluid injection tubing, one or more fluid injection operations to inject a fluid into the subterranean formation, wherein the fluid injection tubing is positioned within a casing in a wellbore;
- detecting, using one or more sensing devices, the seismic vibrations transmitted into and passing through the subterranean formation, wherein the one or more sensing devices are positioned along an outer surface of the casing or between the casing and the subterranean formation;
- and
- outputting, from the one or more sensing devices and using a single communication line that is communicatively coupled to the one or more sensing devices, one or more output signals representative of the detected seismic vibrations.
