... of the screening tool is a solubility-parameter-based approach to screening CO2 injectants containing impurities for miscibility against a range of crude oils. This technology, combined with worldwide operating experience, has been used to evaluate EOR potential in reservoirs across a full range of pressure...

... Abstract In tight gas reservoirs, horizontal wells have been used to increase reservoir contact and hydraulic fracturing has been applied to further extend the contact of the reservoir. Point source solution has been used to describe the flow behavior. The method was advanced to the volumetric...

... in the SAGD process shows that the relative condensation times of solvent and steam result in different films of gas solvent, liquid solvent, and water along the fluid interface. There is an optimal solvent type and concentration ratio range for a particular reservoir and operating condition. The solvent...

... Abstract Hydraulic fracturing is the most effective method for improving hydrocarbon production in low or ultra-low permeability oil reservoirs, but the majority of selected wells for fracture stimulation are considered "risky" because of significant water cut increase after stimulation...

... data and it can be successfully applied globally to both clastic and carbonate reservoirs with use of logs and core data to define petrofacies. Artificial Neural Networks (ANN) mimics biological information processing mechanisms. They are typically designed to perform a nonlinear mapping from a set...

... Abstract One of the important parameters in capacitance-resistive model (CRM) for the prediction of production performance is f ij , representing the fraction of injection rate of injector i flowing toward producer j . However f ij was usually assigned to unity when a reservoir...

... and horizontal wells in a particular field. This field is located in the Southern part of Iran, with two separate carbonate reservoirs, R1 and R2. R1 is on the top and R2 in the bottom. An impermeable layer separates the two reservoirs. In this field about 50% of drilled wells are horizontal. Production results...
