Fiber-optic based Distributed Strain Sensing (DSS) measurements have significantly improved our understanding of hydraulic fractures in unconventional reservoirs. We can constrain fracture length, height, density, and azimuth from qualitative interpretations of cross-well DSS data. Recent studies also demonstrated that geomechanical strain induced by production pressure depletion can be monitored. This presentation will demonstrate the quantitative interpretation of field observations through geomechanical modeling and history matching, which further adds value to DSS measurements in unconventional reservoirs.
