3 reasons to invest

Optimal for surfactants and brine

With the integrated piston you can increase the pressure without adding more fluid. This allows you to to keep the surfactant concentration constant and corrosive fluids are restricted to the chamber only.  
 

Easy to use

Theta High Pressure has plenty of smart solutions simplifying your work. The sample port enables direct introduction of your sample with a syringe and direct cleaning of the same sample line without passing through a pump. With our optional automatic pump the pressure can be changed with just one click. 

Intuitive software

Highly intuitive with high functionality. The OneAttension software facilitates your experiments and provide instant results. The software features live analysis and automatic measurements.

Mimic the real world

There are plenty of applications where conditions are harsh. Take enhanced oil recovery for example. Theta High Pressure is designed with the conditions of an oil reservoir in mind. In short, the closer you are to the real world when conducting your experiment, the better the result. 

The wettability of rock and interfacial tension are both vital parameters in enhanced oil recovery, since they directly affect oil displacement and mobility. These properties are dependent on both pressure and temperature. It is therefore important to measure them under conditions reflecting the oil reservoir. It is the very first step when you want to optimize your processes to increase the oil yield.
