Full-waveform inversion of microseismic events including moment tensors and layer depths

Rodriguez, Ismael Vera (Schlumberger) | Le Calvez, Joel (Schlumberger)


Results are presented on the application of an optimization solver for full-waveform inversion (FWI) in a synthetic microseismic monitoring scenario. The optimization solver is based on a heuristic algorithm that does not require knowledge about the gradient of the cost function. The optimized variables are the sources origin times, locations and moment tensors, and the earth model velocities, Thomsen parameters and depths of interfaces. The application to noise-free data offers encouraging results to continue the assessment of the algorithm in more realistic scenarios of microseismic monitoring.
