INTRODUCTION |
Rock-Eval/TOC results were obtained for samples from 27 cores of Devono-Mississippian shale in or adjacent to the Liard Basin area of British Columbia. Samples have been analyzed using a Rock-Eval pyrolysis technique in the Geological Survey of Canada organic geochemistry laboratory in Calgary. All samples were run on a Rock-Eval 6 Turbo instrument.Every non-confidential core of Devono-Mississippian shale in the Liard Basin was sampled in the fall of 2013. The cores came from 9 different boreholes that intersected several stratigraphic units including the Golata, Banff, Besa River, Exshaw, Kotcho, Muskwa, Otter Park and Evie formations.
Depths in feet are listed when that is the original unit of measure on the core box. The following cores had poorer recovery and the estimated depth for individual samples from these cores have more uncertainty: TRANSEURO BEAVER D-064-K WA0325 core 1; BP ENERGY GROUP DEER LAKE A-090-I WA531 core 1, 21; IOE DUNEDIN D-075-E WA1331 core 16, 17; TRANSEURO HZ BEAVER D-A064-K WA02547 core 6; TRANSEURO BEAVER B-019-K WA2563 core 1 and EOG MAXHAMISH D-012-L WA21643 cores 1-5, 7, 8, 10, 11.
Other previously published rock-eval/TOC results are available for cuttings of Devono-Mississippian shale from several wells in the in the Liard Basin area (Fowler et al., 2007, Obermajer et al., 2012; McMechan et al, 2013) and one surface section of the Besa River Formation (Ferri et al., 2011).
