Due to unsatisfactory sweep efficiency of gas injection, foams, CO2 foams in particular, are utilized to reduce residual oil saturation. Conventionally, generation and stabilization of CO2 foams are achieved by surfactants. However, foams, stabilized via this traditional method, tend to sustain...
CO2-Responsive Surfactants for Enhancing Heavy Oil Recovery: from Fundamentals to Bench-Scale Demonstrations in Canadian Oil Sands ExtractionDownload
Interfacial properties at the oil-water interface are of key importance to various operations in the petroleum industry, especially in the aqueous-based heavy oil recovery process. However, different operation stages often require different interfacial properties, which could be conflicted with...
This research was undertaken to study the performance of paraffinic solvents at higher temperatures for heavy oil/bitumen recovery. Heavy oil or bitumen saturated glass bead packs, Berea sandstone and carbonate cores were used in the experiments to represent different types of pore structures,...
