IDENTIFYING ORIENTATION CLUSTERS FROM MICROSEISMIC DATA.

摘要

Systems, methods and software can be used for analyzing microseismic data from a subterranean zone. In some aspects, a plurality of basic planes are each defined from a subset of the microseismic data and each have an orientation relative to a common axis. Clusters of orientations of the basic planes are identified adaptively based on the extent of variation in the orientations. The number of orientations associated with each of the clusters is then identified.
