Sensitivity Analysis Over Injection Fluid Concentration of ASP Flooding to Enhance the Oil Recovery from Depleted Oil Reservoirs

Chemical methods have been growing with day-by-day modification since their invention but still, something is missing. As a matter of fact, chemical concentration plays important role either chemicals injected individually or combined thus, to find out best concentration and proportion is necessary. This study presents different models were generated from given data with appropriate properties for enhancing oil production starting Alkaline, Polymer, Surfactant, Alkaline Polymer, Alkaline Surfactant, Surfactant Polymer and Alkaline Polymer Surfactant. In this study, simple black oil simulator is used to avoid complication of chemical reactivity and just observed the influence of injection fluid on overall productivity from reservoir by chemical enhanced oil recovery technique. The models revealed capabilities of original field scenario as sensitivity analysis over injection fluid concentration was conducted and reservoir simulator gives accurate result and number of options. The result from simulation shows higher concentration drives more oil but to avoid cost issues productivity time can be elevated and equivalent recovery can be observed. Additionally, it was revealed that ASP has given ultimately good performance with concentration of 30% Alkaline, 35% Polymer, 35% Surfactant. Further, to justify the results, Response Surface Methodology (RSM) technique was used for performing accurate analysis over results with help of software. &nbsp
