Drop Shape Analyzer – DSA100HP

Wetting and surface tension under extreme pressures and temperatures
Our DSA100HP is our high-quality solution for the precise measurement of contact angle and surface tension and interfacial tension under high pressures and temperatures, primarily for tertiary oil recovery. The DSA100HP combines our Drop Shape Analyzer – DSA100 for optical drop shape analysis with a high-quality measuring cell for high-pressure applications up to 1750bar. It determines the surface tension, and analyzes the wetting of oil-bearing rock by surfactant solutions under the extreme pressure and temperature conditions found in reservoirs. The results help in the extraction of oil from layers of rock in the most effective manner using tertiary oil recovery (EOR) methods such as steam or surfactant flooding, and thereby increase the yield. The instrument equally reliably measures the wettability by gases which liquidize under pressure, for example for optimizing extraction processes with carbon dioxide.

Investigations under storage conditions for crude oil
The accurate and easy-to-use dosing units of our high-quality DSA100HP measuring system dispense drops onto solid samples in order to measure the wetting at high pressures and temperatures based on the contact angle. The instrument also enables measurements to be carried out on solids in a surrounding oil phase. The result shows how well the oil can be extracted from the rock by wetting the rock with an aqueous phase.

The precise measurement of surface tension under storage conditions using the DSA100HP is very informative in the characterization of a surfactant solution which is used for flooding a crude oil reservoir. This should be as low as possible to ensure that the rock is well wetted. The interfacial tension between oil and flooding solution, which can likewise be measured with high precision, should also be as low as possible to enable the oil to be mobilized by the aqueous phase. The measurement results help to optimize oil-water emulsions in order to realize the full potential of a reservoir.
