ABSTRACT
Nine (9) selected ditch cutting samples collected from Bright-1 well obtained from the Nigeria Geological Survey covering depths ranging from 7770ft to 8590ft. Were the samples were subjected to visual Sedimentological analysis, Acid test and palynofacies slide preparation. The slides were evaluated under Transmitted light microscope using point counting techniques. Only one (1) lithofacies- the dark grey mudstone lithofacies (M1) was identified in the succession. M1 is dark grey coloured, with clay-silt particle size, with weak effervescence. From the palynofacies analysis, the Amorphous organic matter(AOM) was the most dominant proportion with 75%, 15% palynomorphs, and 5% phytoclast were also preserved. Deductions from the proportion of organic constituents reveal that the sample is made of Type II kerogen, Total Organic Carbon(TOC) 3- 10 wt%, The predominance of AOM present in the samples indicates the samples were deposited under dysoxic- anoxic paleoxygenation, with an intermediate paleosalinity samples were deposited far from source and environments of deposition were delineated as based on palynofacies studies which is the marine environments.
