MONITORING SUBTERRANEAN FLUID MOVEMENT USING DISTRIBUTED ACOUSTIC SENSING

摘要

Some aspects of what is described here relate to seismic profiling techniques. A seismic excitation is generated in a first directional wellbore section in a subterranean region. A seismic response associated with the seismic excitation is detected by a fiber optic distributed acoustic sensing array in a second directional wellbore section in the subterranean region. Fluid movement in the subterranean region is identified based on the seismic response. In some cases, the fluid movement is identified in real time during well system operations.
