Paper presented at the 53rd U.S. Rock Mechanics/Geomechanics Symposium, June 23–26, 2019
Paper Number: ARMA-2019-0123
... ABSTRACT: During production from gas reservoirs the formation pressure decreases, leading to increased levels of effective stress. As a result, the reservoir rock is compressed and deformed, leading to displacement of overlaying formations, which can propagate all the way to the ground...

Paper Number: ARMA-2019-0113
... purpose of this work is to develop a general coupling between fluid flow equation and deformation of fractured media. To quantify the deformation of fracture during production, the geomechanical part used a porous elastoplastic damage model as its basis to investigate relationships between fracture...

... induced subsurface deformation, fracturing, surface subsidence, and aquifer interference is largely controlled by local lithological conditions, mining methods and mine layouts. Thus it is imperative to develop methods/tools that, unlike empirically based strata desaturation height estimation methods, can...

ABSTRACT: In this paper, we integrate hydraulic fracture and geomechanical modelling with microseismic data to quantify deformation and stress field evolution as a predictive tool, as well as to provide a calibration and microseismic workflow. Our approach utilizes simulated fractures as well...
