Abstract: Distinction Between Deltaic and "Deep Water"
Sands, Gulf Coast Province, Based on Analysis of
Small Samples
By
The Tertiary to recent geologic record of the Gulf Coastal
Province includes significant amounts of sand deposited in
deltaic and "deep water" environments. Interpretation of the
correct environment of deposition of any deltaic or deep-water
sand is of significance because depositional environment
controls the trend, shape, and, at times, the dimensions and
quality of sand reservoirs. Interpretation of depositional
environment is best undertaken using conventional cores. In
the Gulf Coastal Province, conventional cores are taken
infrequently, whereas sidewall cores and cuttings samples are
much more abundant. These small samples can be used for
environmental interpretations at a sophisticated level.
Petrographic analysis of thin sections prepared from a
wide range of Gulf Coast sidewall cores and cuttings samples
demonstrates that quantifiable changes in composition and
texture can be used to differentiate between deltaic and "deep
water" sands. These data can be particularly informative
when used in conjunction with gamma ray, S.P., and resistivity
curves from geophysical logs. End_of_Record - Last_Page 2---------------
