    Synthesis and Characterization of Triethanolamine Derivative of Sodium Dodecy l Sulphate and its Use in Enhanced Oil Recovery

    By Ajay Mandal, Abhijit Samanta, Keka Ojha, Ashis Sarkar

    Abstract: The paper deals with the synthesis and characterization of a new surfactant and its use in Alkali-Surfactant- Polymer (ASP) flooding in enhanced oil recovery (EOR). The material has been synthesized from sodium dodecyl sulphate and triethanolamine. The synthesized surfactant has been characterized by measuring the surface tension of its aqueous solution and it has been found that the surface tension of derivative surfactant is much lower than that of pure …

    Extraction and Characterization of an Eco-Friendly Surfactant for Its Use in Enhanced Oil Recovery

    By Ajay Mandal, Abhijit Samanta, Keka Ojha, Ashis Sarkar

    Abstract: Experimental studies have been performed to explore the suitability of an eco-friendly surfactant in enhanced oil recovery. In this respect, herbal surfactant has been isolated from soap nut and characterized by its morphology and physico-chemical properties. The extracted surfactant reduces the interfacial tension significantly over a wide range of concentrations. A series of flooding experiments have been carried out using the extracted surfactant and substantial incremental recoveries have been observed …

    Characterization and Stability Analysis of Crude Oil-in-Water Emulsions

    By Ajay Mandal, Shashikant Kumar, Chandan Guria

    Abstract: AbstractProduced water in the form of oil-in-water emulsion is the largest waste stream generated during the oil and gas production. Characterizations of oil-in-water emulsion in terms of stability study with respect to oil droplet size distribution, oil content, total dissolved solids, salinity with respect to time and rheological property have been investigated in the present work. Particle size distributions of freshly prepared oil-in-water emulsion of different crude oil concentration and …
