Total organic carbon in weight percent (logarithmic scale), taken fromBarker, C.E., 1989, Rock-Eval analysis of sediments and ultimate analysis of coal, Mesaverde Group, Multiwell Experiment Site, Piceance Basin, Colorado, Chap. N in Law, B.E., and Spencer, C.W., eds., Geology of tight gas reservoirs in the Pinedale Anticline area, Wyoming, and at the Multiwell Experiment site, Colorado: U.S. Geological Survey Bulletin 1886, 11 p.
Vitrinite reflectance, Ro, in percent (logarithmic scale), taken fromNuccio, V.F., and Johnson, R.C., 1989, Thermal history of selected coal beds in the Upper Cretaceous Mesaverde Group and Tertiary Wasatch Formation, Multiwell Experiment Site, Colorado, relation to hydrocarbon generation, Chap. L in Law, B.E., and Spencer, C.W., eds., Geology of tight gas reservoirs in the Pinedale Anticline area, Wyoming, and at the Multiwell Experiment site, Colorado: U.S. Geological Survey Bulletin 1886, 8 p.
Vitrinite reflectance measurements were originally made by V.F. Nuccio, R.C. Johnson, N.H. Bostick, and V.L. Freeman, U.S. Geological Survey, and by Amoco Production Co.
Note: Well logs are from well MWX-1, total organic carbon samples are from wells MWX-1, MWX-2, and MWX-3, and vitrinite reflectance samples are from wells MWX-1 and MWX-2.
