DSA100HP – High-pressure instruments for measurements under oil reservoir conditions

Substantially increased pressure range and simplified dosing for contact angles and interfacial tension

In oil recovery using flooding techniques, the interfacial and surface tension are important variables when it comes to mobilizing the oil bound in the reservoir rock. Equally important is the wettability of the rock as measured by the contact angle – this determines whether re-wetting takes place and the oil can detach. In order to be able to measure these variables under the pressure and temperature conditions of a reservoir, we have now redesigned our DSA100HP as a product range line with versions optimized for specific pressure ranges. The DSA100HP is now available in three variants.

Measuring instruments up to 40 bar and up to 690 bar, in each case at temperatures up to 200 °C, cover the low to medium pressure range. The new, heatable Mini Dosing System – MDS, which requires only a low sample volume and is distinguished by particularly easy handling and cleaning, is available for these versions. The measuring range is substantially extended with the third variant up to 1750 bar at up to 250 °C. This will enable you to obtain reliable data even under extreme reservoir conditions.
All designs allow the sample and the dosing capillary to be positioned flexibly from the outside, thus enabling several contact angles to be measured on one sample with very little effort. An external gas connector is provided as standard, for example for measurements with liquid or supercritical CO2. The DSA100HP is therefore also of interest for optimizing high-pressure extractions, in which surface tension and wetting likewise play an important part.

Your Technical Consultant at KRÜSS will be pleased to tell you about the appropriate DSA100HP configuration for your application, and inform you of special versions, for example for corrosive liquids such as brine, or for measurements up to 300 °C.
