Sensitivity Analysis and Optimization of the Effective parameters on ASP Flooding Compared to Polymer Flooding Using CMG-STARS

Ali Mohsenatabar Firozjaii* and Moradi S

Polymer and ASP flooding are two popular chemical enhanced oil recoveries (EOR) method for increasing oil recovery in the tertiary stage of oil production. Many parameters, effect on the performance of these methods. In this paper, fractional factorial design for eight variables is considered to determine the number of simulations. CMGSTARS is used to create a 1/6 inverted 7 spots with two wells. 64 runs for polymer and ASP are considered and the effect of parameter as single and two parameter interactions is discussed. The results show ASP flooding has better performance to increase oil recovery factor compared to polymer flooding in oil wet carbonate reservoir. Over there, connate water saturation has a main effect on recovery factor. On the other hand, two parameters interaction effect, are different for ASP and polymer flooding. Finally, a regression model based on variables is generated for estimating the recovery factor in polymer and ASP flooding.
