Advancing recovery by refining surfactant proportion as a chemical enhanced oil recovery application

Abstract

One of the most requesting and promising techniques in Enhanced Oil Recovery (EOR) is the utilization of synthetic compounds to remove extra oil, keeping the ecological concerns and strength of the reservoirs. The objective of this paper is to choose a particular grouping of surfactant that could upgrade Ultralow Interfacial pressure among oil and Water. And, arrangement of smaller scale emulsion through Emulsion Test. The methodology adopted in this work has been done through conductivity estimation of eight diverse surfactant proportions to decide stable Critical Micelle Concentration (CMC). This proportion has been tested with various groupings of electrolyte and alkali for middle layer smaller scale emulsion. Through conductivity test CMC has been resolved at 450 ppm, It has been tried with various concentrations of electrolyte and soluble base for middle layer smaller scale emulsion. Third layer have been noticed at NaCl 1.0 wt% and Alkali 0.5 wt%. At this specific proportion Interfacial Tension (IFT) among Oil and water has been diminished.
