A Multi-Domain Approach to Understanding Microseismic Data in a Tight Gas Play

Abstract

Abstract In fluvial, multi-layer, tight-gas program, the acquisition of microseismic data together with the development of stress models and production models can significantly influence a development program. Often, the lack of data gathering pre and post microseismic acquisition introduces knowledge gaps that demonstrate inconsistencies between the various engineering domains. In this study, varying completion strategies and monitoring techniques were implemented together with postfracture modeling and production modeling (via rate-transient analysis techniques) to understand and explain the location of microseismic events. This paper presents the agreements and differences observed between the stress models developed (and fracture diversion/limited entry observations), fracture half-lengths (from fracture modeling and production analysis), microseismic events and current geological understanding.
