Utah FORGE: Milford Triaxial Test Data and Summary from EGI labs
Six samples were evaluated in unconfined and triaxial compression, their data are included in separate excel spreadsheets, and summarized in the word document. Three samples were plugged along the axis of the core (presumed to be nominally vertical) and three samples were plugged perpendicular to the axis of the core. A designation of "V"indicates vertical or the long axis of the plugged sample is aligned with the axis of the core. Similarly, "H" indicates a sample that is nominally horizontal and cut orthogonal to the axis of the core. Stress-strain curves were made before and after the testing, and are included in the word doc. The confining pressure for this test was 2800 psi. A series of tests are being carried out on to define a failure envelope, to provide representative hydraulic fracture design parameters and for future geomechanical assessments. The samples are from well 52-21, which reaches a maximum depth of 3581 ft +/- 2 ft into a gneiss complex.
Data from triaxial testing of sample GNS-4, that is nominally horizontal and cut orthogonal to the axis of the core, under a confining pressure of 0 psi.
This is the data from triaxial testing of GNS-2 sample, that is nominally horizontal and cut orthogonal to the axis of the core, under a confining pressure of 8000 psi
This is the data from the triaxial testing of sample GNS-1, that was nominally horizontal and cut orthogonal to the axis of the core, under 2800 psi.
This is the data from triaxial testing of sample GNS-5, that was aligned with the axis of the core, under 2800 psi.
This is the data from triaxial testing of sample GNS-6, that was aligned with the axis of the core, under 8000 psi.
This a report of the triaxial tests at EGI, which describes and shows the equipment, proceedures, and results.
This is the data from triaxial testing of sample GNS-7, that was aligned vertically with the axis of the core, under 0 psi pressure.
This is a spreadsheet that summarizes the important data from each of the six tests.
