INTRODUCTORY SUMMARY'
One composited core Chip sample from a 40' interval in an
unidentified North Slope well was analyzed for Foraminifera and
palynology. Standard processing methods were used for both
disciplines, CONOCO was only charged for the Foraminifera analysis
as per your instructions in the letter of September 12, 1990. We
did the paly analysis on our own because we know that often one
discipline will get r%sults when the other discipline is indeter-
minate in this area.
