Investigation of Oil Recovery Improving through Surfactant Flooding; Design Program Scenario

Abstract

Chemical flooding is one of the major EOR techniques particularly for reservoirs where thermal methods are not applicable, that chemical flooding may be polymer flooding, alkaline flooding, surfactant flooding, or a combination of them. The application of designing a chemical flooding program is strongly affected by the current economics, reservoir oil type, and crude oil price. In this project, mechanisms of different chemical methods will be discussed, and design chemical flooding program by using a laboratory scale and programming method, this project is mainly about making a design of surfactant flooding program, that to make a good program, choosing the optimum surfactant concentration is very important, also economic study is very important in designing the program to know if the project is profitable or not to identify its efficiency, and choosing the better type of surfactant for the reservoir is very important to increase the hydrocarbon recovery, results of this project proved that the surfactant has goof effect on wettability of rock that it increases the rock wettability to water and that increase the hydrocarbon recovery.
