Predicting the Behavior of Engineered Reservoirs
NRAP reservoir models are used to predict the evolution of pressure and saturation (CO2 vs brine) at the reservoir—seal boundary over time from initiation of injection through long-term stewardship.
NRAP is utilizing and adapting a number of commercial and research codes for the simulation of detailed processes related to fluid flow and reaction in the reservoir. For the first generation reduced-order models, NRAP relied on process models built in CMG’s GEM and LBNL’s TOUGH2.
NRAP has developed a reduced-order model (ROM) for a sandstone reservoir with properties similar to the Vedder formation at the Kimberlina site in California.
NRAP has integrated this reservoir ROM into the CO2-PENS system model.
