The Multiwell project is the field testing phase of the DOE Western Gas Sands Stimulation Sub-program. Two wells, 130 ft apart, have been drilled in Garfield County, Colorado (Sec. 34 T6S R94W1) to a depth of about 2545 m. They are referred to as M WX-1 and 2. To predict and understand the geometry, intensity, and extent of fracture in the medium around a well in an in situ fracturing test, we need to know the mechanical (Equation of State) properties of the rock. In this informal report we present the laboratory measured mechanical properties of a sandstone from a depth of 2405 m, in Well MWX-l. The mechanical properties included in this report are tensile strength, compressive strength under triaxial compressive loading, stress-strain relations under triaxial compressive loading, and pressure-volume (P-V) behavior under hydrostatic compression. The mechanical properties of a silstone from the 1994-m depth in M WX-l were reported in a previous informal report (Lin, Nov. 1982).
