Abstract
The project focused on evaluating the CO₂ sequestration potential of high-permeability saline aquifers by analyzing core data collected from stratigraphic wells drilled at an injection hub location. Two conventional composite cores were tested under reservoir conditions in accordance with EPA guidelines. The objective was to assess the experimental data, identify limitations and uncertainties in the measurement techniques, and build and calibrate 1D core flood simulation models for the two composites. By conditioning the models with experimental results and applying appropriate boundary conditions, the project aimed to adjust relative permeability curves and rock properties to achieve reliable history matches, ultimately providing robust parameters for full-field reservoir simulations.

Abstract
Field X in Louisiana has historically been operated by Company A, with horizontal wells drilled in the dome of the structure. The Lower Taylor Sand, located at the base of the Cotton Valley Group, is now planned for development by New Dawn Energy in the flank area of the anticline. To support this effort, a mechanistic model was requested by the sponsoring company to evaluate the main factors influencing oil and gas recovery from several proposed horizontal wells. These wells are planned with 1,200 ft spacing within two 1,000-acre blocks, positioned as close as possible to the best existing horizontal producer (Well 1) in the same tight calcareous sandstone formation. A 3D simulation model was developed to history-match the fractured Well 1 and to forecast performance under various development scenarios. As requested by the sponsoring company, the same fracture geometry as Well 1 was used to maximize both oil and gas production. Results showed that drilling three horizontal wells in each acreage block could achieve a recovery factor of approximately 8% for oil and 78% for gas.
