Experimental Design Applications for Modeling and Assessing Carbon Dioxide Sequestration in Saline
Project No: FE0004510
The research effort integrates well completion design including effects of geomechanical stresses into engineering design and operations of an enhanced oil recovery (EOR) site to assess geologic and fluid effects and factors on CO2 injection, capacity, and plume migration. The DOE Rocky Mountain Oilfield Testing Center (RMOTC) Teapot Dome site (Figure 1) has collected seismic and reservoir data that was targeting the Crow Mountain aquifer. These data are being used as a realistic proxy to evaluate the feasibility of the proposed methods.
A geomechanical reservoir tool (STIMSIM) will be coupled with a commercial reservoir transport tool (reservoir simulator -- RESSIM) and a method for seamless data input and output will be developed. This integrated wellbore and reservoir software tool will be integrated with a static geocellular reservoir model. Dynamic fluid flow in the reservoir and the migration of the CO2 plume due to vertical and lateral heterogeneity, pressure migration, fault, and seal integrity during injection will be evaluated. In addition, the effects of complex structures in the geologic CO2 storage process on plume migration in a brine aquifer will be investigated, and the impact of multilateral horizontal well (opposed to vertical or single lateral wells) deployment on the potential of CO2 capacity and injectivity and trapping mechanisms will be evaluated (Figure 2).
