Abstract
This study presents a synthesis of
palynomorph attributes recovered from X-Well Onshore Niger Delta.
Integrating qualitative and quantitative analyses of terrestrial and marine
palynomorph assemblages, ditch cuttings intervals (2960-3050 m) were analysed
for age dating, biozonation, lithostratigraphy and environment of deposition.
The samples were subjected to standard palynological laboratory processes,
which involved the maceration of samples with Sodium-Hexametaphosphate as the
reagent solution to remove the drilling muds. Lithologically, the samples
consist predominantly fine to medium grained sand with shale intercalations,
conformed to the paralic Agbada Formation. The palynormorph recovery was good
within the sampled intervals. Based on the recovered key marker palynomorph
species identified such as: Nympheapollis clarus, Multiaerolites formosus,
Peregrinipollis nigericus, and Stereisporites sp. The stratigraphic intervals
infiltrated Late Miocene age. Palynological data enhanced precision in
subsurface interpretation. This study highlights how palynology contributes to
refining stratigraphic frameworks, and supporting hydrocarbon prospect
evaluation in the Niger Delta. The sediments deposited in shallow marine
depositional environments. The findings reaffirm that palynology remains a
cost-effective and reliable method for assessing sedimentary sequences and
identifying hydrocarbon-bearing zones.
