Identifying an axis of a stimulated reservoir volume for a stimulation treatment of a subterranean region

摘要

In some aspects, a boundary is computed based on locations of microseismic events associated with a stimulation treatment of a subterranean region. A major axis of a stimulated reservoir volume (SRV) for the stimulation treatment is identified based on the boundary. In some examples, the boundary is an ellipsoid, and the major axis of the ellipsoid is identified.

1. A method comprising:
collecting, by a microseismic event sensor, microseismic event data representing locations of microseismic events associated with a stimulation treatment of a subterranean region; computing, by operation of data processing apparatus, a boundary based on the locations of microseismic events associated with the stimulation treatment of the subterranean region, the boundary comprising a three-dimensional (3D) convex hull computed based on the locations of microseismic events; computing a stimulated reservoir volume (SRV) for the stimulation treatment by computing a volume of the 3D convex hull; and identifying a major axis of the SRV for the stimulation treatment based on the boundary.
