A system for enhanced oil recovery of heavy crude oil using chemical flooding

Abstract

The present invention relates to a system for enhanced oil recovery of heavy crude oil using chemical flooding comprises a chemical solution preparation unit configured to prepare alkaline (A), alkaline surfactant (AS), and alkaline surfactant polymer (ASP) solutions; a characterization unit comprising a drop shape analyzer configured to measure surface tension, interfacial tension, and contact angle, and equipment for measuring density, pH, and viscosity; and a wettability assessment unit configured to analyze interaction of chemical flooding solutions with crude oil and porous media. The system enables comparative analysis of alkaline flooding, alkaline surfactant flooding, and alkaline surfactant polymer flooding for determining feasibility of heavy crude oil recovery from reservoirs having API gravity between 19° and 23°.The present invention relates to a system for enhanced oil recovery of heavy crude oil using chemical flooding comprises a chemical solution preparation unit configured to prepare alkaline (A), alkaline surfactant (AS), and alkaline surfactant polymer (ASP) solutions; a characterization unit comprising a drop shape analyzer configured to measure surface tension, interfacial tension, and contact angle, and equipment for measuring density, pH, and viscosity; and a wettability assessment unit configured to analyze interaction of chemical flooding solutions with crude oil and porous media.
