The Current Status of SRV Fitting Methods based on Microseismic Event Points

Tight oil and gas reservoirs require hydraulic fracturing as a stimulation measure due to their low porosity and permeability characteristics, which enhances their economic benefits. Microseismic events are generated during hydraulic fracturing and monitored by geophones. The stimulated reservoir volume (SRV) is derived from the study of microseismic event point sets. Research by scholars both domestically and internationally has shown that SRV is significantly positively correlated with production. To effectively manage reservoir operations, it is necessary to reasonably calculate and evaluate the SRV induced by hydraulic fracturing. Currently, the methods used for SRV calculation are somewhat disorganized. This paper organizes these methods and introduces their basic principles.
