VITRINITE REFLECTANCE ANALYSIS OF THE INTERVAL 1070-7870 FT
SULLIVAN # 1 WELL, ALASKA
Introduction
This repod describes the vitrinite reflectance analysis of 11 cuttings samples from the
Sullivan #1 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, pitting, scratching or the proximi.ty
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 co!our 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 6130 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 (1977a0b) 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.

VITRINITE REFLECTANCE SUMMARY
M..aturi!;y Zones Based on Ro
1,070-7,930ft Onset of Maturation
Onset of Maturation Zone: 1070-7930fl
This zone commences at 1,070ft (Ro=0.588%). This sample contains 50 read-
ings, many of which are excellent. At 2,170ft an excellent histogram distribution
shows an Ro=0.542%. The Ro is slightly depressed until 6~550ft (Ro=0.5%).. It then
.begins to-increase' down'to 7,0'30ft (Ro=0.53%). The-only 'unreliable' sample is at
6:030ft whereliHle sample Was present and most readings were poor.
