Paper presented at the SPE Eastern Regional Meeting, October 15–17, 2019
Paper Number: SPE-196585-MS
.... In this paper, we proposed a coupled geomechanics and fluid flow model for early-time flowback in shale oil reservoirs. The fluid flow model is coupled with an elastic fracture closure model through finite element methods. In this study, three stages are modeled: fracture propagation, well shut-in...
