Wettability Test Cell
The wettability test cell is a test cell used in G205 testing to classify crudes. The cell is operated under pressure and contains a central reference pin surrounded by 20 measuring pins arranged in a circular pattern. Wettability is the determination of a crudes ability to maintain an oil wet surface. The measured resistance between the steel pins and reference pin is the test criterion. The crude oil is then classified as water-wet, mixed-wet or oil-wet.
