Abstract
The present disclosure includes a method for monitoring a subsurface formation including disposing an antenna in a horizontal wellbore, the antenna including a plurality of piezoelectric modules. A voltage signal is applied to at least one of the piezoelectric modules to cause the at least one piezoelectric modules to emit seismic energy into the subsurface formation. A resulting signal is received at a receiver. A property of the subsurface formation is determined based, at least in part, on the resulting signal.

A method for monitoring a subsurface formation comprising:
- disposing an antenna in a horizontal wellbore, the antenna including a plurality of piezoelectric modules distributed along a cable, wherein the antenna extends from an entry point of the horizontal wellbore to an exit point of the horizontal wellbore, where both the entry and the exit points are at a surface of the earth;
- applying a voltage signal to first and second of the piezoelectric modules to cause the first and second piezoelectric modules to emit seismic energy into the subsurface formation, wherein the first and second piezoelectric modules act as seismic sources;
- receiving a resulting signal at third and fourth of the piezoelectric modules, wherein the third and fourth piezoelectric modules act as seismic receivers;
- and
- determining a property of the subsurface formation based, at least in part, on the resulting signal.
A system for monitoring a subsurface formation comprising:
- an antenna configured to be disposed in a horizontal wellbore, the antenna including a plurality of piezoelectric modules distributed along a cable, wherein the antenna extends from an entry point of the horizontal wellbore to an exit point of the horizontal wellbore, where both the entry and the exit points are at a surface of the earth;
- wherein first and second of the piezoelectric modules are selectively configurable as seismic sources that emit seismic energy and third and fourth of the piezoelectric modules are selectively configurable as seismic receivers that receive a resulting signal.
A system for monitoring a subsurface formation, the system comprising:
- an antenna in a horizontal wellbore, the antenna including a plurality of piezoelectric modules distributed along a cable, wherein the antenna extends from an entry point of the horizontal wellbore to an exit point of the horizontal wellbore, where both the entry and the exit points are at a surface of the earth;
- at least one processor;
- and
- a memory including non-transitory computer-readable executable instructions, wherein the executable instructions cause the at least one processor to:
- cause first and second of the piezoelectric modules to selectively emit seismic energy into the subsurface formation, wherein the first and second piezoelectric modules act as seismic sources;
- receive a resulting signal from third and fourth piezoelectric modules, wherein the third and fourth piezoelectric modules act as seismic receivers;
- and
- determine a property of the subsurface formation based, at least in part, on the resulting signal.
