Reservoir Modeling for Carbon Dioxide Sequestration and Enhanced Oil Recovery

Carbon Accounting for Carbon Dioxide Enhanced Oil Recovery

Enhanced Gas Recovery with Carbon Dioxide Sequestration in a Water-drive Gas Condensate Reservoir: a Case Study in a Real Gas Field

Gas reservoirs usually have high recovery due to high mobility and low residual gas saturation, although some of them producing under water-drive mechanism have low recovery efficiency. Encroachment of water into these reservoirs traps considerable amount of gas and increases the maximum residual gas saturation, which results in the reduction of gas and condensate production. Generally, the rec...

An Experimental Study of Surfactant Alternating CO2 Injection for Enhanced Oil Recovery of Carbonated Reservoir

Core flooding experiments were conducted with the objective of evaluating near miscible surfactant alternating CO2 injection and the effect of surfactant concentrations on gas-oil and water displacements in porous media. The core samples were provided from a low permeability mixed wet oil reservoir at 156 °F and 1900 psia. In addition, very few studies of surfactant adsorption on car...

Enhanced Oil Recovery and CO2 Flooding/Sequestration in Carbonates

Process Modeling of Co, Injection into Natural Gas Reservoirs for Carbon Sequestration and Enhanced Gas Recovery

Injection of CO, into depleted natural gas reservoirs offers the potential to sequester carbon while simultaneously enhancing CH, recovey. Enhanced CH, recovery can partially offset the costs of CO, injection. With the goal of analyzing the feasibility of carbon sequestration with enhanced gas recovery (CSEGR), we are investigating the physical processes associated with injecting CO, into natur...
