Summary

Core samples from the Pennsylvanian Kansas City, Marmaton, and Cherokee Groups were collected from the #1 Douglas County Core Hole (N2 S2 SE SW sec. 8, T. 14 S., R. 19 E.; lat. 38.84215°, long. 95.32785°) operated by the Kansas Geological Survey with the aid of a grant from Steve Dixon (Edmond, OK). The well (API # 15-045-21557) was drilled from June 10, 2009, to July 23, 2009, to a depth of 1725 ft (G.L. = 940 ft), with T.D. in the Silurian-Devonian Hunton(?) Group. Core samples of dark shale and coal from this well were analyzed for their desorbed gas content. The samples tested calculate as having the following gas contents:

unit depth (desorbed gas)
Eudora Shale Member 242' 0" to 242' 8.5" (no significant gas)
Muncie Creek Shale Member 438' 4.5" to 439' 4" (no significant gas)
Quivira Shale Member 474' 2" to 475' 0" (no significant gas)
Fontana Shale Member 513' 0" to 514' 10.5" (no significant gas)
Stark Shale Member 548' 0" to 548' 8" (no significant gas)
Hushpuckney Shale Member 573' 9.5" to 575' 0.5" (11 scf/ton)
Nuyaka Creek shale 757' 6" to 759' 2" (8 scf/ton)
Unnamed shale 765' 0" to 766' 0" (no significant gas)
Mulberry coal 781' 3" to 782' 8" (12 scf/ton)
Lexington coal 816' 2" to 817' 2" (25 scf/ton)
Bevier coal 955' 8" to 956' 9" (10 scf/ton)
Croweburg coal 965' 8" to 966' 2" (18 scf/ton)
Mineral coal 995' 0" to 995' 6" (19 scf/ton)
Tebo coal 1041' 5" to 1042' 11" (21 scf/ton)
shale below Tebo coal 1053' 2" to 1054' 1" (no significant gas)
Dbj coal 1180' 6" to 1181' 6" (34 scf/ton)
Drywood coal 1192' 0" to 1193' 2.5" (45 scf/ton)
Drywood coal 1193' 2.5" to 1194' 8.5" (57 scf/ton)*
Rowe coal 1201' 0" to 1202' 5.5" (51 scf/ton)
Neutral coal 1217' 2.5" to 1217' 10.5" (34 scf/ton)
Riverton coal 1271' 1" to 1271' 8" (39 scf/ton)
Chattanooga Shale 1675' 0" to 1676' 0" (no significant gas)
* 71 scf/ton, including residual gas obtained by ball-mill grinding after desorption analysis

The thickest coal beds were the Drywood (32.5 in), Tebo (18 in), Rowe (17.5 in), Mulberry (17 in), Bevier (13 in), Dbj (12 in), and Lexington (12 in). Four coals thinner than 12 in were also encountered.
