Attension High Pressure Chamber can be used in a variety of applications. The applications and industries include:
Attension High Pressure Chamber is an advanced add-on module for Attension Theta, enabling to perform interfacial tension and contact angle measurements in high pressures and temperatures.
The chamber includes a unique piston design which is especially useful in any studies including surfactants. Traditionally, the pressure is increased within a chamber by pumping more fluid into it. However, when surfactants are used in the measurement this will lead to a situation where surfactant concentration will also change while changing pressure.
In order to eliminate the issue, in Attension High Pressure Chamber the pressure can also be increased by using a movable piston inside the chamber. The piston will compress the fluid in the chamber without the need to pump in more fluid. Therefore, both surfactant concentration and measurement pressure can be controlled independently.
Attension High Pressure Chamber is operated with modern OneAttension software. OneAttension includes features such as:
Wettability of CO2 in Enhanced Oil Recovery (EOR)
In order to gain the maximum yield from an oil reservoir, methods grouped under the name enhanced oil recovery (EOR) are used. One common EOR method is to use CO2 to both dissolve and displace oil in a reservoir.
To study the effectiveness of the CO2, the wettability of it can be measured by using interfacial tension and contact angle measurements. The interfacial tension between CO2 and brine, for example, correlates with how easily carbon dioxide can be pumped into the reservoir. Likewise, the contact angle of an oil drop in a carbon dioxide environment gives a measure how well the CO2 can displace the oil on rock surface.
