Drop Shape Analyzer
DSA100HP1750
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.
Applications
-
Surface tension of stimulation fluids and their interfacial tension with oil under storage conditions
-
Wettability of reservoir rock 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
Versatile options for dosing and measuring
With the aid of the dosing units of the DSA100HP1750, the drop liquid and the surrounding phase easily reach the inside of the high pressure cell. Rock samples can be positioned from the outside to measure the wettability at different positions while maintaining the pressure. The flexible design also allows contact angle measurements in a surrounding liquid phase. Precise temperature control up to 250 °C is achieved by means of an electric heater.
Reliable drop shape analysis thanks to high imaging quality
The DSA100HP1750 features a high-resolution camera and a quality zoom lens for accurate display of the drop with optimum size. The high image quality that this achieves leads to a precisely measured contact angle or surface/interfacial tension. Combined with the intelligent image evaluation algorithm of the ADVANCE software, drop shape analysis with the instrument provides exact results.
