The team at Equinor approached Interface with a challenge – develop a replacement for slim tube testing for the determination of Minimum Miscibility Pressure. The measurement is critical in all of Equinor’s fields where gas injection is used or will be implemented, but the cost, time, and logistics associated with the traditional measurement technique was prohibitive.
In close collaboration with Equinor on design, Interface developed a slim-tube style microfluidic device. It was validated by measuring the minimum miscibility pressure of three live oil samples and selected gas mixtures from different fields with different mechanisms. Interface’s technology reduced time per measurement by over 95%, reduced of sample volume by 99%, and eliminating the need for mathematical interpolation of results by increasing the number of measurements taken per sample by 10-20X.
