摘要

The field studied was an Oil Field with light oil reservoir characteristics. In order to increase oil production this field will be applied EOR method in the form of surfactant injection. In this study the type of surfactant that will be used is sodium lignosulfonate (SLS) surfactant using sodium oleate and EGBE formulations in various concentrations. The research carried out was a laboratory study with core flooding and wettability tests on various variations of SLS surfactant solution concentrations. The results of the core flooding test will provide the largest recovery factor of the various SLS surfactant concentrations tested. The same thing will be done in the wettability test. On changes in wettability, the contact angle of various surfactant concentrations that have been formulated will be observed. This study aims to determine the wettability changes of rocks that occur after the injection of SLS surfactants before and after the formulation. Furthermore, the formulations and concentrations of the surfactants which give a smaller contact angle will result in a greater recovery factor.
