... configuration (line drive or 5-spot pattern), (iii) well spacing (500 m or 1 km) and (iv) injectant (miscible HC gas or immiscible HC gas). Simulation models capturing each scheme were developed. Through the injection scheme sensitivity simulation studies, it was concluded that (i) WAG, (ii) line drive, (iii...

... the results of a detailed experimental study aimed at understanding the performance and efficiency of gas injection in carbonate reservoirs. A series of immiscible and miscible gas injection coreflood experiments were performed using limestone reservoir cores under different injection strategies. To minimize...

Simulation results from both natural and water injection cases are used as reference for immiscible gas injection process. The same water injectors were converted to gas injectors to evaluate the three miscible gas injection...

The experimentally verified MMP value of 2690 psi ( Bon et al., 2005 ) and CMG's WinProp predicted value of 3237 psia are considered in this study while deciding immiscible or miscible mode CO2 injection. The oil-water-contact (OWC) and the gas-oil-contact (GOC) are at the depths of 8450 ft and the 9150 respectively...

.... The stage of adjusting pseudo relative permeability curves (gas-oil in this case, because it is the injection of only gas in oil reservoir) is equivalent to a task of history matching. In this case, starting from the coarser model, 100 × 100 m2, miscible fluid model was replaced by the immiscible one...
