Fifty vitrinite reflectance measurements for each sample are taken wherever possible utilizing a Zeiss 01K photometer attachment mounted on a Zeiss Photoscope 1. Each measurement is qualified as to poor (P), good (G) or excellent (E), depending upon such factors as: particle size, pitting, scratching or the proximity to pyritic particles. The measurements of particles 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. Further 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 600 grit, .3 micron and .05 micron polishing procedure on Buehler Automet polishing equipment. This methodology results in a polished mount of unoxidized kerogen. GMC Data Report 84 Page 2/40 Bujak Davies Group Well INSKIN .... 2 The levels of vitrinite ~eflectance are compared to the Thermal Alteration Index (TAI) oI~ Bujak, Barss & Williams (1977a,b) in Table 1 and are subdivided into various levels ol~ thermal maturation for the generation o1: liquid and gaseous hydrocarbons. This generation model will vary l~rom basin to basin depending upon the geohistory and kerogen compositions.

However, recovery in these two samples was 'poor, therefore the reflectance values should not be heavily relied upon. Mar~inalls Mature Zone: 2010-7470ft T~e 2010ft sample is already well within the zone of marginal maturity; Ro = 0.760, with a good distribution of values. This zone may occur higher up in the well, but samples are not available to determine this. The vitrinite reflectance generally increases with depth within this zone. The 5440 and 5970ft samples both contain a large number of readings (Ro = 0.740 and 0.773, respectively) and can be considered reliable values. Other samples with fewer:Ro values have either low recovery, or very small particles and occasional pyrite. Peak of Maturity Zone: 7970-11,230ft The 7970ft sample has an average Ro = 0.830 with 12 readings. The 8370ft sample (Ro = 0.808) has a larger number of values and verifies GMC Data Report 84 Page 4/40 Bujak Davies Group Well INSKIN .... 4 that these samples are within the peak of maturity zone. The lO,790ft sample has slightly lower Ro values relative to other readings within the zone.
