ChemTerra provides complimentary lab surfactant evaluation/optimization testing services in our facility.  If you provide us with crude oil and/or drill cuttings or plugs, we are happy to perform a series of tests including demulsification, column drainage, interfacial tension reduction, and spontaneous imbibition to either optimize surfactant concentrations or perform blind comparisons to a surfactant of your choice.  Please contact us for more information by sending an email to
