ROCK-EVAL/TOC DATA FOR 30 WELLS FROM BEAUFORT-MACKENZIE BASIN

Lloyd R. Snowdon, Mark Obermajer, Dale R. Issler


Cuttings samples with various spacing intervals have been analyzed using a Rock-Eval/TOC pyrolysis apparatus over the depth intervals noted below for 30 wells from Beaufort-Mackenzie region. Wet drill cuttings samples were sealed in cans at the well site and shipped to the Calgary laboratory of the GSC. The samples were washed to remove drilling mud and other obvious contaminants and then air dried at <40 ºC. An attempt was made to obtain a representative aliquot by selecting a random sample of several grams of the dried sample and then pulverizing this material either in a stainless steel mill or by hand using a mortar and pestle to ensure thorough mixing.

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 Northwest Territories Geoscience Office (NTGO) at the time of analyses (prior to 2000). 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 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.
