This detailed stochastic techno-economic Monte Carlo model is the outcome of a research project and a published paper that estimates and evaluates the economics of enhanced oil recovery. Model is developed in the GoldSim environment and categorizes cost objects into three main modules: injection, production, and CO2 recycling. Where, each module is composed of a number of lower-level sub-modules that represent specific cost objects. The techno-economic model utilizes reservoir simulation inputs and results, such as production rate and composition, injection fluid rate and composition, and pressure, to provide detailed costs and revenue estimates for injection, production, and CO2 recycling, with respect to defined scenarios of Waterflood, Water Alternating Gas, and Surfactant Alternating Gas.
