Abstract
A method for measuring multiple rock properties using a multi-stage indentation test is provided. The method includes measuring load and displacement versus time on an indentation measurement unit, while preforming the multi-stage indentation test. The multi-stage indentation test includes indenting a saturated specimen to full load to generate a line segment 1, releasing the load on the saturated specimen to generate a line segment 2, indenting the saturated specimen to full load to generate a line segment 3, holding the loading until the displacement curve levels off to generate a line segment 4, and reducing the loading to zero to generate a line segment 5.
