ABSTRACT:
A method for hydraulic fracture imaging consistently integrates ground deformation data and microseismic data. A time sequence of hydraulic fracture images is computed from the combined data by first computing an orientation and location of the fracture. A size of the fracture (e.g., length, width, and opening) and detailed shape is then computed consistent with the computed orientation using a stochastic optimization procedure. This procedure may be performed by selecting a candidate model of the fracture consistent with the computed orientation, computing a predicted surface deformation from the candidate model (e.g., using elastic crack theory), computing a predicted seismic activity from the candidate model (e.g., using Dieterich seismicity rate theory), and comparing the predicted surface deformation and predicted seismic activity with the collected ground deformation data and earthquake locations derived from the collected seismic activity data.
