Interfacial Tension Measurement at Oil Well Condition with High Pressure Unit

Interfacial tension between oil and surfactant solution and wetting of rocks and sand depend on pressure and temperature. KRÜSS (Germany) HP32XX high-pressure cells are used throughout the world to reproduce deposit conditions in the laboratory – with the standard configuration up to 690 bar (≈ 10,000 psi) and up to 200°C. For other conditions KRÜSS can provide customised solutions.

The pendant drop method is used to characterise oil/brine/surfactant-interfacial tension. Contact angle measurements of oil and surfactant solution on hard surfaces provide a definitive image of the wetting of the stone by the oil. A powerful camera and a high-quality lens ensure that both optical methods are carried out with utmost precision. The proven image analysis software also evaluates and manages the data.
