Paper presented at the 55th U.S. Rock Mechanics/Geomechanics Symposium, June 18–25, 2021
Paper Number: ARMA-2021-1831
... to mathematical inequalities rather than hard constraints on model outcomes. A system for scoring models based on their compliance with each type of constraint was developed and provided the basis for model inversion. The inversion scheme solves for unknown model parameters by maximizing the weighted sum...

... three different gas shale formations, namely, Haynesville, Eagle Ford, and Barnett. Using three different sets of model parameters, we conduct numerical simulations of borehole closure in shale formations to investigate the impact of material-level creep responses on time-dependent deformation processes...

The WinBUGS software was used to compute the posterior predictive distributions of the model parameters and the deviance information criterion (DIC) corresponding to the models. The DIC and the percentage of correctly predicted rockburst category...

... challenge associated to the coupled flow-geomechanics models is the inherent uncertainty associated with model parameters, which stems from the always-difficult description of complex geological structures in the subsurface. In addition, for problems where seismicity could be potentially associated to a CO...
