Abstract
Mass, or changes in mass, of a rock specimen are measured to determine the changes in saturation of a rock specimen. Measurements can be obtained in test environments of high temperature or high pressure or both. The mass is rigidly attached beneath a stiff spring and made to vibrate or oscillate at a characteristic frequency. The frequency of oscillation is detected and the data then used to determine mass of the specimen.
