ROCK-EVAL/TOC DATA FOR 12 JEANNE D'ARC BASIN WELLS

This Open File Report contains data from Rock-Eval/TOC pyrolysis of cuttings samples analyzed on a 10 meter spacing over the depth intervals noted below, from twelve wells from the Jeanne d'Arc Basin, offshore Eastern Canada.

The present report is a very belated addition to the series Open File Reports containing organic geochemistry data from the Jeanne d’Arc basin (Snowdon and Fowler, 1986; Fowler and Snowdon, 1988, 1989; Fowler et al., 1990, 1991; Fowler and Obermajer, 2001a, 2001b, 2002a, 2002b ). With the exception of Brents Cove I-30 and South Nautilus H-09, borehole datasets have been available from the NRCan BASIN database (http://basin.gdr.nrcan.gc.ca/index_e.php). As for the previous Open File Reports containing Rock-Eval/TOC data, there has been little attempt to remove spurious results and caution must especially be advised in giving too much credence to parameters such as Hydrogen Index (HI) and Tmax from those samples with low total organic carbon (TOC) contents or S2 values. It should also be noted that drilling additives used in several of the wells affected the data quality negatively and made interpretation more difficult. The tops used were those in McAlpine (1990b) or were provided later by the same author, based on lithostratigraphy outlined in McAlpine (1990a).
