Abstract: Processes to prepare lightly branched surfactant products comprise combining at least one olefin and a coordination-insertion catalyst under conditions such that at least one oligomer product is formed. The surfactant products comprise a main carbon chain containing an average of between 0.5 and 2.5 branches, wherein more than 50% of the branches are ethyl branches, wherein the branches are located more than one carbon away from each end of the main carbon chain in more than 20% of surfactant product molecules

Abstract: A method for recovering oil from an oil bearing formation including the steps of: i) recovering an oil-water mixture from the oil-bearing formation; ii) separating at least a portion of the oil from the oil-water mixture to form a produced water; iii) adding a polymeric alkylene oxide surfactant having a Mw of less than 10000 Da to the produced water; iv) passing the produced water through a polymeric membrane to form a permeate stream and a retentate stream; and v) injecting the permeate stream into the oil bearing formation.
