Abstract
In some aspects, a closed boundary is computed based on locations and location-uncertainty domains of microseismic events associated with a stimulation treatment of a subterranean region. The closed boundary encloses the locations and respective location-uncertainty domains of multiple microseismic event data points. An error bound of a stimulated reservoir volume (SRV) for the stimulation treatment is identified based on the closed boundary.

A method comprising:
- computing, by operation of a computer system, a closed boundary based on locations and respective location-uncertainty domains of microseismic events associated with a stimulation treatment of a subterranean region, the closed boundary enclosing the locations and location-uncertainty domains, wherein computing the closed boundary comprises:
- identifying boundary points on an uncertainty boundary of each location-uncertainty domain;
- and
- computing a convex hull based on the boundary points;
- identifying an error bound of a stimulated reservoir volume (SRV) for the stimulation treatment based on the closed boundary;
- and
- assessing stimulation treatment field development, evaluating efficiency of the stimulation treatment, modifying, and managing a plan for the stimulation treatment plan using the closed boundary.
