Investigation of anionic in place of cationic surfactants onto oil wet carbonate surfaces for improving recovery

This paper depicts the utilization of sodium dodecyl sulphate (SDS) that replaces and enhances traditional use of cationic surfactant that is acetylene tri alkyl bromide (CTAB) for improving oil recovery. The SDS was assessed in Alkaline Surfactant Polymer (ASP) slugs containing regularly utilized surfactants with polymers. The impact of SDS on interfacial tension (IFT), adsorption and recovery was contrasted with that of a CTAB in these applications. The SDS was seen as good with saline solutions containing high total dissolved salt and greater volumes of double cations. They can be utilized in saline solutions without the requirement for softening and they give preferable outcomes over traditional CTAB in frameworks where either can be utilized. The SDS has the favourable position of improved recovery with unsoftened saline solution. Their non-reactive properties make them especially appropriate for ecologically delicate applications at on land and offshore oil fields.Copyright (c) 2022 Elsevier Ltd.
