Coupled geomechanical reservoir simulation

"Founded by Department Of Energy, the Plains CO₂ Reduction (PCOR) Partnership is investigating the Williston Basin as a candidate for sequestering CO₂ emissions from power plants. The State of Missouri, a member of PCOR, lies at the outermost point on the proposed transportation route and consequently faces the highest CO₂ compression and transportation costs. In order to minimize the cost of CO₂ sequestration, it is desirable to find a storage site within the state. The Lamotte sandstone is identified as a suitable sequestration aquifer formation in Missouri with acceptable permeability, porosity, extension, rock strength and water salinity. Using the finite element analysis package ABAQUS for the geomechanical analysis and the fluid flow simulator Eclipse for pore pressure determination, this work looks at pore pressure - stress coupling which has significant implications for failure mechanism, fault reactivation and caprock integrity. The present work also suggests the use of Pressure Transient Analysis (PTA) to quantify the lateral fluid flow boundary type and differentiating between open, closed and infinite systems. The present work also suggests a new boundary condition, Semi-Open, which is a transitional lateral boundary condition between Fully Open and Closed boundary conditions. Results of the present work provide a coupling module that can be used to conduct coupled geomechanical analysis for CO₂ sequestration projects, facilitate the building of 3D mechanical earth models and provide insight into the role of boundary conditions with respect to CO₂ storage capacity. The coupling procedure is utilized to evaluate CO₂ storage potential and assess the geomechanical risks for CO₂ sequestration in a candidate storage site in the North-Eastern part of the state of Missouri for sustainable CO₂ sequestration"--Abstract, page iv.
