Wetting and interfacial tension under pressure conditions of reservoir stimulation
The DSA100HP1750 performs precise measurements of contact angle as well as surface tension and interfacial tension at pressures of up to 1750 bar and temperatures of up to 250 °C. The main focus of the instrument lies in the optimization of reservoir stimulation in oil recovery by influencing both wetting of rock and water/oil phase interactions. The DSA100HP1750 combines our expertise in the field of optical drop shape analysis and the know-how of our partner EUROTECHNICA in high pressure applications.
