Drop Shape Analyzer Drop Shape Analyzer – DSA100HP (DSA100HP1750 configuration) Wetting and surface tension under extreme pressures and temperatures The Drop Shape Analyzer – DSA100HP is our high-quality solution for the precise measurement of contact angle as well as surface and interfacial tension under high pressures and temperatures, primarily for tertiary oil recovery. The DSA100HP combines the DSA100 setup for optical drop shape analysis with a measuring cell for high-pressure applications up to 1750 bar. 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 enhanced oil recovery (EOR) methods such as steam or surfactant flooding and thereby increase the yield. Measuring methods and options ■ Surface tension of flooding solutions and their interfacial ■ Contact angle measurement using a sessile drop ■ Surface tension of a liquid in gas or interfacial tension tension with oil under reservoir conditions ■ Wettability and extraction of oil from oil-bearing rock ■ Pressure extraction by means of liquefied gases, e.g. carbon dioxide ■ Development of surfactants for liquid gases between two liquids using a pendant drop ■ Upside-down pendant drop measurement of an oil drop in water ■ Measurements at pressures up to 1750 bar and temperatures betwe

Versatile options for dosing and measuring With the aid of the dosing units of the DSA100HP, 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. Sample positioning with closed pressure chamber. Either a gas or a liquid can be added as surrounding phase....
