Abstract:
A method for predicting time-lapse seismic timeshifts in a three-dimensional geomechanical system including defining physical boundaries for the geomechanical system. In addition, one or more reservoir characteristics such as pore pressure and/or temperature history are acquired from multiple wells within the physical boundaries. The method also includes determining whether a formation in the geomechanical system is in an elastic regime or a plastic regime. The method also includes obtaining first and second seismic data sets for the geomechanical system, taken at first and second times. The method also includes running a geomechanical simulation to simulate the effects of changes in pore pressure or other reservoir characteristic on time-lapse seismic timeshifts in the formation.
