Experimental Characterization to Support a FAWAG Project in an Offshore Pre-Salt Field

Abstract

Abstract This work describes the experimental characterization of foam flow in a Pre-Salt field, carried out to support the implementation of a FAWAG pilot currently under evaluation. Foam performance was quantitatively determined as a function of surfactant concentration, water composition, gas composition, water saturation, oil saturation, and rock permeability. Surfactant adsorption on the rock and its partition in the oil phase was also measured. These results were used to estimate parameters to be entered into foam models available in commercial reservoir simulators. Other fields subject to gas injection for secondary or tertiary recovery purposes, or even CCS/CCUS projects, are potential beneficiaries of this information.
