Biostratigraphy Study Of Uquo Well 12, Oml 13, Of Uquo Field, Niger Delta

Palynological analysis was carried out on twenty ditch cutting samples which were gotten from Uquo well 12 located at Uquo, Akwa Ibom state. The depth ranged from 1720ft to 2860ft. The aim of the study was to determine the age, depositional environment and paleoecology penetrated by the well. The palynological analysis yielded sufficient palynomorph (pollen, spores, Acritach). The most occurred palynomorphs recovered were Smooth monolete spore, Verrucatosporite tenellis, Foraminiferal test lining, Polypodiaceiosporites sp. The dominance of mangrove pollens; Zonocostites ramonae and Psilatricolporites crassus, this indicates that the sediments were likely deposited in a mangrove environment under a wet climate during the Pliocene. The age range penetrated by the well is late Miocene to Early Pliocene because of the co-occurrence of the index species of Cyperaceopollis spore, Nympheapollis lotus and Stereisporites spore seen at 1900ft and 2440ft. Since the study area is foreshore environment and the characteristics are: moderately low to moderately high coastal brackish water swamp community elements, moderately high hinterland fresh water swamp/forest elements, absence of sporadic of marine element therefore samples here has relatively few content
