However, interactions between crude oil and foam destabilize the foam and reduce its efficiency. Many researchers have examined the effects of interactions between crude oil and foam with a focus on the negative effects of these interactions. The goal of this study is to investigate the potential of a new hybrid Enhanced Oil Recovery (EOR) method termed Low Salinity Water Assisted Foam flooding (LSWAF) in sandstone rocks. This method involves the injection of Low Salinity Water (LSW) followed by the alternate injection of a Surfactant Aqueous Solution (SAS) and CO2 gas. LSW solutions were prepared using different salinities of NaCl, KCl, CaCl2, and MgCl2. Experiments were carried out using two types of crude oil with a different Total Base Number (TBN) and Total Acid Number (TAN), namely crude oil A and B. In terms of changes in wettability, for both crude oils, the experimental results revealed that the test with LSW of 500 ppm KCl outperformed other salinities. For crude oil with a higher TBN, the proposed hybrid technique led to improved performance. The insights presented in this study provide a good reference for further research in this area. © 2018 Elsevier B.V. date: 2019 publisher: Elsevier B.V. official_url: https://www.scopus.com/inward/record.uri?eid=2-s2.0-85057622036&doi=10.1016%2fj.petrol.2018.11.035&partnerID=40&md5=bc229a5261a2d77f893d66d537574f3e id_number: 10.1016/j.petrol.2018.11.035 full_text_status: none publication: Journal of Petroleum Science and Engineering volume: 174 pagerange: 716-728 refereed: TRUE issn: 09204105 citation: Shabib-Asl, A. and Ayoub, M.A. and Elraies, K.A.
