ANALYZING FRACTURE CONDUCTIVITY FOR RESERVOIR SIMULATION BASED ON SEISMIC DATA

摘要

Some aspects of what is described here relate to seismic data analysis techniques. A seismic excitation is generated in a first directional wellbore section in a subterranean region. The subterranean region includes fractures defined in subterranean rock. A seismic response associated with the seismic excitation is detected in a second directional wellbore section in the subterranean region. Seismic response data based on the seismic response are analyzed to identify spatial variations in fracture conductivity for the subterranean rock. A reservoir model is calibrated based on the identified spatial variations in fracture conductivity. In some cases, the reservoir model is calibrated in real time during production operations, and the reservoir model can be used for reservoir simulations.
