Abstract

In this investigation, coupled-geomechanical modeling is performed using the COMSOL Multiphysics software, during carbon dioxide injection into the deep Khuff carbonate reservoir. Khuff reservoir is a carbonate reservoir that is capped by the low permeability Sudair shale geological layer. The main objective of the study was to evaluate safe values of the carbon dioxide injection parameters for the Khuff reservoir that will act as a benchmark for the similar reservoirs and injection scenarios around the globe. Carbon dioxide was injected for a period of 10 years into the reservoir and the corresponding variations in the reservoir pore-pressure and ground uplift was evaluated. The Mohr-Coulomb failure criterion was utilized to perform the stability analysis for the Khuff reservoir during carbon dioxide injection.
