TENNECO MIDDLETON ISLAND, ALASKA
Vitrinite and visual kerogen slides were prepared for the interval of
1,700-11,950 feet, to determine the levels of thermal maturity and
compare these to previous-visual estimates of maturity.
The data can been seen on Attachment 1 in strip chart form.
Levels of maturity ranged from pregeneration to early peak oil genera-
tion, or a visual level of 4. Kerogen type is at best mxed and can be
seen on Attachment 2. Reflectance levels of approximately 0.60-0.65%
Ro are reached at the base of the well. It is doubtful that source
rocks at this level of maturity would be capable of significant expul-
sion; however, addition.al thermal input (depth or heat) could explain
the oil seeps found in the area.
