Chemical injection field development strategies to increase oil recovery factors using reservoir simulation (Case study in JHD field)

Recently, most oil fields have entered the tertiary stage, which is called Enhanced Oil Recovery. It is applying technology by injecting a particular substance into the reservoir through injection wells, then produced through production wells with specific patterns. One method that is being developed and is also used in field development is chemical injection. There are three types of chemicals used, Alkaline, Surfactants, and Polymers. This research will present a study of strategies to use chemical injection in the JHD field. Four scenarios will be simulated using the CMG STARS 2012 to get the maximum oil recovery factor. The first scenario is the base case, using 12 production wells and six water injection wells. The second scenario is injecting polymers. The third scenario is injecting surfactants, and the fourth scenario is injecting surfactants-polymers. Prediction of the recovery factor obtained until 2031 is for the first scenario is 25.8%, the second scenario is 28.85%, the third scenario is 31.05%, and the fourth scenario is 34.69%. From the four scenarios, it is found that Surfactant-Polymer injection has maximum results compared to other scenarios.
