PROBLEM:
Cuttings samples submitted
by Jim Rankin for determination
of maturity (TAX - Vo) and microscopic organic analysis
(MOA) indices.
RESULTS:
Note: Microscopic organic analysis (MOA) was not attempted
because the kerogen
is highly altered event o the
point of having a mineral-like appearance.The
vitrinite plugs weren o t useful i n identifying the
kerogen types either.
The TAI indices are not based
on palynomorphs. as
the entire suite
of samples is apparently barren,
but'on the back-ground material. Using'the background organic debris, although less reliable,
seems justified when maturity indices are post
mature. Laboratory flow sheets state these samples
were very difficult
t o process because oxidation
was not possible. This might imply the organic
fraction was already oxidized.

SAMPLE DESCRIPTION:
SAMPLE PREPARATION:
Following athoroughvisual
examination, the samples were ground for analysis.
No special preparation was necessary.
ANALYTICAL DETERMINATIONS:
A s pertheinstructions
containedinthe
Work Order,totalorganiccarbon
(T .O.C.) determinationsand Rock-Eval pyrolysis was performed on each of the
samples. Thetabulatedresults
from boththeseanalysesarepresentedin
Table
I. The Rock-Eval pyrogramsareplottedinFigures
I-A, I-B, and I-C.
Although the total organic carbon content
of the samples ranges from low, to in
one .case,verygood,
none of the samples appeartobe
capable of generating
significantquantities
of oil or gas.Based
on the physicalappearance
of the
samples and on the limited S2 yields, we conclude thatthe sectionrepresented
by
these
samples has
probably
experienced
a
moderate to extreme
thermal
history. No Tmax values were obtainable from any of thesamples,duetothe
low S2 yields.
One sample in particular appears to best demonstrate the effect
of the probable
thermal influence. Sample P-4016-9 hasan extrememly hightotalorganiccarbon
content ( 3 . 5 5 % ) buthasvery
negligible S2 yieldanda
very small Hydrogen
Index.Apparently,anyhydrocarbonthat
could havebeenproduced
from this
organicfacieshasalreadybeengeneratedandreleased.
