ABSTRACT:
Saturation variations are obtained by displacing a first fluid (for example water) that initially saturates a sample (1) coated with resin (2) by injecting therein, through a first end plate or cap (3) and by means of a pump (7), a second fluid (for example oil). The mixture flowing out through an opposite end plate (4) is collected in an initially filled two-phase separator (9) placed on an electronic balance (10). The first excess fluid flows towards a vessel (13), and the progressive accumulation of the second fluid in separator (9) leads to a variation in the total weight. A programmed processor (14) computes permanently the saturation values of the sample with respect to the first and to the second fluid, from the measured weight variations of separator (9). The method and device can be used for laboratory measurements of rock samples for example.
