      abstract = {Microfloral biozonation and stratigraphic correlation of Miocene-Pliocene sediments of wells V, W, and X were carried out. One hundred and eighty (180) ditch cuttings at 20 m depth intervals of (2740-4000m), (2220-3420m), and (460-1540m) from the Mungo Field were analysed for zoning, dating and correlating of stratigraphic intervals of the wells. The samples were subjected to standard palynological laboratory processes, which involved the maceration of samples with acids and bases to remove the drill muds. Lithologically, the samples consist predominantly fine to medium grained sand with shale intercalations which conformed to the paralic Agbada Formation. The recovery yielded low to moderate palynomorphs within the sampled intervals. A total of eight hundred (800) palynomorph species were retrieved from the wells. Four palynozones were established, which are: zones A: Nympheapollis clarus -Retistephanocolpites gracillis, zone B: Peregrinipollis nigericus - Retibrevitricolporites protrudens zone C: Stereisporites sp - Cyperaceopollis sp, and zone D: Multiareolites formosus ? Monoporites annulatus. The stratigraphic intervals infiltrated Late Miocene - Early Pliocene age based on the recovered age diagnostic species such as Multiareolites formosus, Verrutricolporites rotundiporus, Crassoretitriletes vanraadshoveni and Racemonocolpites hians. The sequence stratigraphic interpretation probably points to the penetration of ?7.4/Me*Ma MFS - 2.7/Ge*1Ma MFS belonging to the Tortonian - Gelasian stages. The assessment of the wells showed that more palynomorphs were recovered from X well followed by V and W wells. The sediments of the wells deposited in a shallow marine environment within the upper to lower shoreface depositional environments.},
