Available in PDF, EPUB and Kindle. Book excerpt: The effect of confining pressure on the pore volume of some tight sandstones from the Uinta Basin, Utah, was investigated. A new method based on the pressure-volume relationships of a gas was developed and used to measure pore volume reduction. The results were compared with the results obtained using the more common method that involves the measurement of liquid expelled from a saturated core and were found to be in good agreement. Pore volume compressibility of the samples studies is in the range of values reported by other investigators and ranges from 2.0 x 10−6 to 1.3 x 10−5 pv/pv/psi at a confining pressure of 5,000 psi.
