ROCK-EVAL/TOC DATA FOR ELEVEN NE BRITISH COLUMBIA BOREHOLES (map areas 94-I to 94-P)

Martin G. Fowler, Mark Obermajer & Lloyd R. Snowdon


Cuttings samples have been analyzed using a Rock-Eval/TOC pyrolysis apparatus on a typically 30 foot or 10 metre spacing over the depth intervals noted for the eleven wells listed below from northeastern British Columbia. The samples are from the Geological Survey of Canada archive set for British Columbia wells and therefore a maximum of 100 mg of material is available for any depth. Duplicate or repeat analyses cannot be run if an instrument failure is suspected and thus the data are presented in an unedited form and must be used with caution. Every effort is made to obtain a representative sample from the vial of cuttings, but because of the small sample size, mixed lithology samples may not be completely representative and mixed lithology intervals may yield some scatter in the data. Depth units used (feet or metres) are those in which the original well was drilled and logged, and in which the samples are currently labelled. Formation names and depths listed at the end of each well are those obtained from the files of the BC Government Oil and Gas Commission. These stratigraphic tops, which are also used in the GSC-Calgary SAMS database, are in most cases likely the tops provided by the original operators of these wells. In this open file, no attempt has been made to review the stratigraphy. As most of these wells were drilled several decades ago, before the stratigraphy in this area of NE British Columbia was reviewed, some terms are no longer in current use and some of the tops may be incorrect, and hence misleading. Therefore, the stratigraphic data should be treated with caution.
