Gas EOR is often challenged by high mobility of injected gases such as CO₂ or hydrocarbon gas limiting gas-oil contact and oil recovery. ELEVATE™ CS and CSU surfactant products address this challenge from temperature, salt and oil tolerant water-soluble surfactants to unique gas-soluble systems that can be injected directly in the injection gas line. These products offer gas conformance in conventional and gas containment in unconventional reservoirs to help operators recover otherwise inaccessible oil while maximizing the value of every injected molecule.
