Home My WebLink AboutGMC Data Report No. 124Total organic carbon, rock-eval pyrolysis, and vitrinite reflectance data from the Union Oil Co. OCS ¥-08q9-2 (Hammerhead No. 2) well Received 30 May 1989 Total of 9 pages in report Geologic Materials Center Data ReP°'rt No. 124 HAMMERHEAD #2 AND CORONA #1 GEOCHEMISTRY Initial pyrolysis screening of these wells revealed some 7-8 intervals with high S2 yields. Additional, more intense sampling was'carried out to derive .a vertical profile through the source section to establish thickness and proneness of the intervals. The richer samples were then extracted for further geochemical characterisation but this revealed the presence of severe contamination in both wells. The contaminant wa-s extremely soluble, immediately turning dichloromethane black and totally swamping the GC traces obtained. The contaminant is some form of plasticiser or possibly lubraglide, a common Beaufort Sea drilling additive. No further geochemical characterisation was possible, and the high S2 yields measured during screening are, at least in part, due to contaminant.
