RECODAS 185 is a surfactant designed for enhanced oil recovery (EOR) and is predominantly composed of dialkylbenzene sodium sulfonates. It is formulated to achieve ultra-low interfacial tension (IFT) when used in the alkaline surfactant polymer (ASP) and surfactant polymer (SP) methods. It is typically used alongside co-surfactants or co-solvents in EOR formulations.

Product Application

EOR or tertiary recovery encompasses several techniques to extract more crude oil from reservoirs in comparison with conventional techniques. Primary and secondary oil recoveries can usually achieve one third of the reservoir’s total as long as the other two thirds remain behind. Only through the use of EOR techniques can large quantities of that remaining crude oil be recovered. Surfactants improves the displacement efficiency to encourage the flow of oil trapped in the rock through the reduction of the interfacial tension between water and oil.
