Measurements of the vertical distribution of the minimum principal in situ stress in the lower Mesaverde group (7300 to 8100 ft depth, 2225 to 2470 m) at DOE's Multi-Well Experiment site have been made by conducting small-volume, hydraulic-fracture stress tests through perforations. Accurate, reproducible results were obtained by conducting a number of repeat injections in each zone of interest using a specially designed pump system, modified high-resolution electronic equipment, and a down-hole shut-off tool with a bottom-hole pressure transducer. Stress tests were conducted in marine sandstones and shales as well as a coal, mudstone, and sandstone in a paludal depositional environment. These tests provide a detailed stress distribution in this region. 19 references.
