Fifty ditch cuttings from Kombo-001 well
were sampled and analysed for their palynological
content in order to determine the palynostratigraphy,
Palynozonation and depositional systems in Kombo-001
well. The study followed standard sample lithologic
descriptions and palynological sample preparation using
the non-mineral acid method of palynological sample
preparation. The sample description which were
presented as lithological log, sand/shale ratio and
gradational profile showed alternation of sand and shale
characteristic of the Agbada Formation in the Niger
Delta. The palynomorphs identified in Kombo-001 well
are abundant and diverse including gymnosperm and
angiosperm pollen, pteridophyte and bryophyte spores,
dinoflagellates, foraminiferal test linings, freshwater
algae, dinocysts, diatom and fungal spores. The
palynoforal assemblage consists of 45 (forty-five) pollen
species representing 37 (thirty-seven) pollen genera, 18
(eighteen) pteridophyte and bryophyte spore species
which comprise of monoletes, triletes and alete, and few
fungal spores, freshwater algae and diatoms. The
palynostratigraphy of Kombo-001 well indicated
dominance in mangrove pollen species suggesting
deposition within coastal to marginal marine settings
under wet climatic condition. The palynological zones
identified included P820 and P830 with boundary
marked based on Quantitative Base Occurrence of
Stereisporites sp. at 9110 ft and corresponding to late
Miocene. Generally, the depositional systems and
systems tract of the studied intervals in Kombo-001 well
lies within the highstand systems tract (HST).
