Enhanced Recovery and Gas Storage

Our experts have significant experience evaluating enhanced recovery projects, including waterflooding, CO2 injection, miscible flooding, and thermal recovery projects. We build numerical simulation models that are calibrated to reservoir performance and used to optimize and predict recovery from these types of projects. In some cases, projects include the creation of detailed static geologic models of the subsurface geology.

Our firm also has extensive experience evaluating underground gas storage reservoirs. Expertise includes investigating the feasibility of developing new gas storage projects, as well as the evaluation of the critical operating parameters necessary to achieve optimum field performance from existing underground gas storage reservoirs. We have been involved in the follow-up projects that take the design specifications from the feasibility studies, reservoir simulation models, and surface facility evaluations, and implement these recommendations to actual field operations.
