Propagating fracture plane updates

摘要

Systems, methods, and software can be used to update fracture planes based on microseismic data from a fracture treatment. In some aspects, a first fracture plane is updated based on a microseismic event in a microseismic data set associated with a fracture treatment. The first fracture plane is one of multiple previously-generated fracture planes. A second, different fracture plane of the previously-generated fracture planes is updated to account for information generated by updating the first fracture plane based on the microseismic event.

1. A computer-implemented method for analyzing microseismic data from a fracture treatment, the method comprising:
in response to a microseismic event being detected and added to a microseismic data set, updating, by data processing apparatus, a first fracture plane based on the microseismic event in the microseismic data set associated with a fracture treatment of a subterranean zone, the first fracture plane being one of a plurality of previously-generated fracture planes; updating a second, different fracture plane of the plurality of previously-generated fracture planes to account for a parameter that is modified by updating the first fracture plane based on the microseismic event, wherein the parameter comprises at least one of:
an updated orientation of the first fracture plane;an updated size of the first fracture plane;an updated list of unassociated microseismic events; oran updated list of microseismic events associated with the first or second fracture plane; cascading updates until a terminating condition is reached, each update accounting for prior updates to other fracture planes; and generating a model of the subterranean zone based on the updated first fracture plane and the updated second fracture plane.
