Abstract
Surfactant flooding is one of the successful techniques employed in enhanced oil recovery (EOR) to extract the remaining original oil in place after primary and secondary recoveries are performed. Selection of the right EOR surfactant is an important but demanding task due to a series of screening procedures that need to be executed to have a comprehensive evaluation. This article presents the experimental work done on the initial screening of ten surfactants from three different classes, namely nonionic, anionic, and amphoteric. The screening was completed with three consecutive series of testing, which are surfactant compatibility, phase behavior, and interfacial tension (IFT). Results showed that an anionic surfactant, sodium decylglucoside hydroxypropyl phosphate, passed all tests with the lowest IFT value of 8 × 10−3 mN/m at 0.1 wt% of surfactant concentration.
