Title: Stochastic fault permeability computation and modeling of fault hydraulic properties for geologic carbon sequestration in siliciclastic sequences

Abstract:This talk will be organized on two parts. In part (1), we present an open-source algorithm (PREDICT) to estimate the intrinsic permeability of the fault core in soft siliciclastic basins. PREDICT models realizations of the fault core consistent with the stratigraphy, and computes probability distributions for the directional components (dip-normal, strike-parallel and dip-parallel) of the fault permeability tensor.  In part (2), we demonstrate how to apply PREDICT to build geologically-realistic fault hydraulic property scenarios including porosity, permeability, relative permeability and capillary pressure. For this application, we use a geologic model of the Miocene section offshore Texas, in the Gulf of Mexico, which is a key US asset to deploy industrial-scale carbon capture and storage.
