Rock-Eval/TOC results for cuttings samples from the Paktoa C-60 well, Beaufort-Mackenzie Basin, northern Canada / [by] C. Jiang, M. Obermajer and A. Su. : M183-2/7794E-PDF

Cuttings samples were collected from the Paktoa C-60 well of Beaufort-Mackenzie Basin for Rock-Eval/TOC analysis. As the samples have been hand-picked based on the lithology of the corresponding intervals and have been washed lightly with tap water, effect of drilling mud contamination on the Rock- Eval results, especially on Tmax and S2 values is considered minimal as evident from the shape of S2 peaks on hydrocarbon FID pyrograms. Thermal maturity represented by Tmax indicates that the Tertiary Taglu sequence intersected at the Paktoa C-60 well is immature with respect to oil generation, even at the total depth of around 2400 m. A high content of volatile and semi-volatile hydrocarbons as reflected by production index (PI) is determined in the 1293-1311.5 m interval where significant oil discovery was made from drill stem test (DST#4).
