Oil & Gas
Tertiary oil recovery methods, such as surfactant flooding or steam flooding, are based on the extraction of oil from the rock in a reservoir. The oil is then mobilized with water in an emulsion. Our tensiometers contribute to improving this process by measuring the interfacial tension between the oil and the surfactant solution. In addition, our instruments determine the wetting of the rock based on the contact angle in order to optimize the oil extraction. These investigations are similarly important for natural gas recovery by means of hydraulic fracturing and for the pumping and processing of bitumen.
