Alaska Geologic Materials Center Data Report No. 277 Vitrinite Reflectance Analyses For 60 well cuttings samples For Dan Seamount, UNOCAL PETROLEUM LTD. Analyses càrried out by R.M Bustin 09/21/97 GMC Data Report 277 . Page 1 of 65 Results of Vitrinite Reflectance Analyses The vitrinite reflectance analyses of the 60 provided samples are summarized in Table 1. Because of the mineral matter content of some cuttings, the samples were hand picked for coal prior to crushing and preparation of pellets for refleCtance.. N d difficulties were encountered in any of the analyses however in many samples there is clear evidence of exposure to high temperatures for short duration. This evidence includes high reflectance rims around many particles and local evidence of vessiculation. Because of the lower reflectance (maturity) of the samples exposure to high temperatures for even a short time would account for the oxidation rims. The high reflecting oxidation rims are restricted to the particle edges thus the temperature must have existed for a relatively short time and thus natural processes (i. e. burial, hydrothermal fluids) can be ruled out with fair confidence. It is thus suspected that the cuttings samples were dried (likely at the well site?) over an open flame or on a hot plate. Because the high reflectance rims are restricted to the rims of particles it was possible in most samples to obtain good reflectance data. Samples in which high temperature rims are particular pronounced are marked in Table 1 as "heat affecÚ~d". Normally with cuttings samples the highest r~t1ecting vitrinite are the indigenous population in a sample since the cavings would normally be derived from higher stratigraphic intervals which would be less mature. In the cuttings samples which are heat affected this assumption can not be made and thus care must be exercised in the rigorous interpretation of the reflectance values. In the analyses samples there is a general increase in reflectance with depth (as anticipated) with few anomalies. Such results lend credence to the detennined values and also provide a means by which the anomalous values can be identified. Histograms for all samples are provided in appendix i.
