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; padicle size, pitting, 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. 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 unoxidozed kerogen. The levels of vitrinite reflectance are compared to the Thermal Alteration Index (TAI) of Bujak, Barss & Williams (1977a,b) in Table 1 and are subdivided into various levels of thermal 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.

Zone: 480-1.620fl All three samples in this zone have execellent histogram distributions. The first, at 48Oft has an Ro=0.525%. Other samples in this zone are also in agreement with this Ro. Marginally Mature Zone: 1.970-9.430ft The 1,970ft sample has an excellent histogram distribution (Ro=0.672%) and is a good indicator of maturity at this depth. Other samples in this zone also have good to excellent histogram distributions. Only the 9,00Oft sample has a significant amount of Cavings and reworked material. The Ro Of the deepest sample is 0.652% which is on the upper edge of the oil window. Other samples in this zone also have similar Ro's.
