Abstract
The process mainly consists in placing a sample previously imbibed with a first fluid into a vessel or bucket containing another fluid of different density and in applying a centrifugal force by rotating the bucket at the end of an arm, so as to study the displacements of the fluids in the sample during at least two distinct phases. During the first phase, the rotational speed is increased so as to drain the first fluid from the sample. During the second phase, the rotational speed is progressively decreased. In order to avoid a discontinuity and to allow an imbibition of the sample, it is important to keep the two fluids in permanent contact with the sample. The amount of fluid produced in the bucket by centrifugation may be determined. The fluid produced may also be transferred into a variable chamber, for example inside the same bucket or a second rotating bucket.
