Reservoir characterization and multiphase flow property in the upper Minnelusa sandstone: Implication for geological carbon storage

Abstract

This report summarizes the reservoir characterization [Wang et al., J. Hydrol., 2022] and multiphase flow property [Kou et al., J. Hydrol., 2021] in a target deep saline aquifer, upper Minnelusa sandstone in Wyoming. Multiscale petrophysical characterization and flow unit classification were carried out to identify two different facies groups: cross-bedded and massive sandstone. Based on the rock typing results, two representative core samples were selected accordingly to conduct coreflooding experiments. Results illustrate that the sub-core scale heterogeneity significantly affects CO2 -brine multiphase flow properties. As a result, the subcore scale heterogeneity should be considered during CO2 injection to reduce the uncertainties in storage and fluid flow. Cited as: Kou, Z., Wang, H., Alvarado, V.
