Home My WebLink AboutGMC Data Report No. 113Vitrinite reflectance data and analysis of the 1,680 - 11,600 foot interval of the PhilliPs Kerr McGee Sullivan No. 2 well Received 9 February 1989 Total of 22 pages in report Geologic Materials Center Data Report No. 113 VITRINITE REFLECTANCE ANALYSIS OF THE INTERVAL 1680-11,600 FT SULLIVAN #2 WELL, ALASKA Introduction This report describes the vitrinite reflectance analysis of 13 cuttings samples from the Sullivan #2 oil exploration well. Fifty vitrinite reflectance measurements for each. sample are taken wherever possible utilizing a Zeiss 01K photometer attachment mounted on a Zeiss Pho- toscope 1. Each measurement is qualified as to poor (P), good (G) or excellent (E). Depending upon such factors as; particle size, pilling, scratching or the proximity to pyritic particles. The measurements of padicles interpreted to be reworked vitrinite are labeled with an' "R" while the measurements of particles interpreted to be caved material are labeled with a "C". A table and a plot of all measurements displayed as a histogram for each.sample are given in Appendix A. A vitrinite reflectance log is included which' displays each histogram at the level of the sample. The material considered as caved is cross-hatched in blue while the material considered to be reworked is cross-hatched in red. The good and excellent samples are coloured in solid green while the poor measurements are coloured in cross-hatched green. Fudher colour copies of this log are available through the Bujak Davies Group. The laboratory procedures for the mounting and polishing of the vitrinite samples follows the methodology described by Davies and Avery (1984) in a triple mount stub with standard 6[]0 grit, .3 micron and .05 micron polishing procedure on Buehler Automet polishing 'equipment. This methodology results in a polished mount of unoxidozed kerogen. The levels of vitrinite reflectance are compared tothe Thermal Alteration Index (TAI) of Bujak, Barss & Williams (1977a,b)in Table 1 and are subdivided into various levels ofthermal maturation for the generation of liquid and gaseous hydrocarbons. This- generation model will vary from basin to basin depending upon the geohistory and kerogen compositions.

Ro 1,680-10,960fl 11,600-11,680f Onset of Maturation Possibly Marginally Mature Onset of Maturation Zone: 1.680-10960ft The zone of onset commences with the sample at 1,680ft, Ro=0.5%. Few readings were taken due to a lack of sample. The following three samples show good histogram distributions with Ro's still near 0.5% to 0.52%. At 6,07Oft (Ro= 0.585%) there is very liHle kerogen present in the sample. The sample is mostly light grey amorphous inorganic material and should not be considered reliable. The 6,60Oft sample shows an-excellent histogram distribution with an Ro=0.56%. At 8,270ftthere is little sample present resulting in few readings. However, the Ro=0.55% is in agreement with other samples. Samples at 9,390ft, 9,91 Oft, 10,870ft and 11,60Oft all contain little kerogen and vitrinite. Even though these samples have Ro's in agreement with one another, they should not be heavily relied upon. Possible Marginally Mature Zone: 11.600-11.680fl The deepest sample at 11,60Oft contains some higher Ro vitrinite (Ro=0.62%) which appears to be from an in situ population. However this population consists only of eight readings and should not be heavily relied upon.
