Ten Berea sandstone core plugs were used in the relative permeability experiments and in the primary drainage capillary pressure measurements. The reduced porosity is around 2122% and the permeability is approximately 450 md. The rate of revolution versus time was developed separately for each range of centrifuge speeds.

The Berea Sandstone occurs throughout much of the Appalachian Basin where it is an oil and gas reservoir and is quarried as a building stone. Because of its uniform porosity and permeability in the quarries at South Amherst, Ohio, it has been used by petroleum engineers in North America as a "model" reservoir sandstone.

Berea sandstone plugs were chosen for the commencing core test, because Berea sandstone is well known as a reference rock. Views of core plugs B1 and B2 are shown in Figure 3 and Figure 4, respectively. The plugs had a diameter of mm. Strain gauges as shown in these figures were used to record axial and radial displacements.

In this work, the timedependent response of fluidfilled sedimentary rock at room temperature and isotropic stress states is experimentally quantified. Drained, undrained, and unjacketed geomechanical tests are performed to measure the poroelastic parameters for Berea sandstone, Apulian limestone, and Opalinus clay (shale).

2O at low capillary numbers in a Berea sandstone rock core under conditions representative of a deep underground saline aquifer. Supercritical CO 2 was found to have a lower residual nonwetting (NW) phase saturation than that of air and CO 2. Supercritical CO 2 behaves differently than gas phase air or CO 2 and leads to a reduction in capillary ...
