Carbon Dioxide Enhanced Oil Recovery (EOR)

An enhanced oil recovery (EOR) technique attracting new market interest is carbon dioxide (CO₂) injection. The major technical challenge for CO₂ EOR is being able to control proper mobility and proper sweep of injected gas. ECLIPSE reservoir simulation software offers you robust and mature modeling of CO₂ EOR. Simulation studies are particularly valuable for assessing the characteristics of a field while designing appropriate EOR strategies and to overcome the technical challenges associated with the injected gas. A calibrated simulation model can be used to predict future reservoir production in a series of potential scenarios, such as drilling new wells, injecting various gases, or stimulation.

The ECLIPSE Compositional simulator

• describes reservoir fluid behavior or compositional changes with depth and provides the ideal solution for studying and analyzing gas injection and secondary recovery
• models the 3-phase compositional effects in depleted gas and oil reservoirs and considers the modeling of gas mixtures in aquifers
• considers reservoir parameters including pressure, temperature, salinity, permeability, and residual gas together with gas mixtures in aquifers
• accurately models the handling of CO₂ injection, allowing analysis of EOR and enhanced gas recovery (EGR) processes 
• models naturally fractured reservoirs and includes simulation of triple-porosity systems for more accurate analysis of carbonate reservoirs.
