Abstract
Palynology and Sequence stratigraphy analyses of the strata penetrated by OL-A well was investigated in other to decipher the age, biozone, and sequence stratigraphic framework using data sets from palynology. A total of thirty three (33) ditch cutting samples within the intervals of 7810-3340 ft were analyzed. Acid method was used for the palynomorph recovery. A total of fifty five (55) palynomorph species were recovered. The section was dated Oligocene-early Miocene due to the occurrence of the diagnostic maker species such as Cicatricosisporitesdorogensis, Arecipitesexilimuratus, Echiperiporitesestelae. A taxon range zone of Cicatricosisporitesdorogensis, concurrent range zone ofArecipitesexilimuratus-StriatricolpitecatatumbusZone and interval zone of Pachydermitesdiederixi-Peregrinopollisnigericus Zone were established. Condensed sections and maximum flooding surfaces were observed from the palynological results and were integrated with the well log to delineate system tracts and other stratigraphic surfaces. The shales of the TST could form potential reservoir seals, while the LST and HST could form good exploration target during hydrocarbon exploration.
