ABSTRACT:
A technique is disclosed for obtaining the true capillary pressure curve directly from experimental measurements. The above said technique is based on the use of a small-size sample being into capillary contact with the sample to be tested, with the usual tail effects being thus prevented. The resulting experimental data does not require complex mathematical processing yielding approximate results.
