Drop Shape Analyzer

High pressure interfacial analysis for flooding methods in EOR

The DSA100HP690 performs precise measurements of contact angle as well as surface tension and interfacial tension at pressures of up to 690 bar and temperatures of up to 200 °C. The main focus lies in optimizing the use and formulation of flooding fluids in enhanced oil recovery (EOR).

The instrument analyzes the wetting of rock as well as phase interactions between oil and water under reservoir conditions. The DSA100HP690 combines our expertise in the field of optical drop shape analysis and the know-how of our partner EUROTECHNICA in high pressure applications.

Applications

• Surface tension of flooding fluids and their interfacial tension with oil under storage conditions

• Wettability of reservoir rock by flooding mixtures in air as well as wetted by oil

Measuring methods

• Contact angle of a drop on a solid surface
• Contact angle using a gas bubble beneath a solid surface in a liquid
• Surface or interfacial tension using the curvature of a drop or bubble at the tip of a needle

Measuring results

• Surface tension of a liquid

• Interfacial tension between two liquids

• Static contact angle

• Contact angle using a bubble in a liquid
