My research interest revolves around the Sequence stratigraphy and evaluations of the petroleum potentials, of the Nigerian Inland basins. It focuses on the integrated techniques on Seismic, well logs, biostratigraphic data, cores, cuttings samples retrieved from the basins for diverse predictions which established rock relationships within a chronostratigraphic framework of repetitive, genetically related strata, bounded by surfaces of erosion, non-depositional or their correlative conformities thus predicting the depositional environments within a time stratigraphic framework and for correlation of sedimentary strata..

(a) Completed

1. Palynology and organic geochemical assessments of the Chad Basin as one of the Nigerian sedimentary basins has established eight palynological zones, chronology and maturation for the diverse lithofacies encountered within the basin. The palynomorph morphologies and their displayed coloration shed light on the maturation and the intense of tectonic activities in the region. The northeastern basin ward decreases in maturation and corresponding increase of TOC suggest increase in sedimentation. The higher thermal maturation at volcanically active basin flanks were the most prospective area where the phase of hydrocarbon expulsion is expected to have been reached.The biomolecular signatures indicated the dominance of marine organic matter with terrigenous source input.

2. Petrophysical evaluation and sequence stratigraphy of Exploratory Fields (OPL and OML) located within Onshore and Offshore, Niger Delta. This study has been able to identify structures necessary for hydrocarbon accumulation, overpressured zones and estimation of hydrocarbon reserves. Structural maps of horizons were in wells containing hydrocarbon bearing zones were produced, showing the trapping mechanism to be mainly fault-assisted roll-over structures, also the stock tank oil in place estimated which was attributed to insufficient drive mechanism and high viscosity.

3. Calcareous nannofossil and Foraminifera biostratigraphic evaluation of ditch and core samples from Niger Delta and Chad Basin.The work from the Niger Delta hasestablished major zones which were erected based on index taxa and fossil assemblages recovered. Condensed sections associated with Maximum Flooding Surfaces were also established. The poor recovery of calcareous nannofossil from Chad Basin made zonation impossible.

4. Sedimentological and palyno-environmental appraisal of the late Quaternary sediments northeastern, Bornu Basin. This work has shown predominant argillaceous and terrigenous mudstone with thin intercalated sandstone beds of point bar deposits of laterally migrating, moderate to high sinuosity river channels. It has also recorded limited number of in-situ palynomorph taxa of late Pliocene (Piacenzian) to Mid-Pleistocene (Emilian) (3.4-0.7m.y) indicating freshwater-lacustrine paleoenvironment

5. Quaternary stratigraphy, palynological and geochemical indices of the Lagos Lagoon Coastal sediments in southwestern Nigeria (Dahomey Basin), presented an evaluation of lithotopes distribution, provenance, environment of deposition and the resulting marine transgression-regression episodes from previous sea level changes.

1. The sustainable groundwater development and management in southwestern Nigeria. This has presented the hydro-geochemical assessments of the shallow groundwater sampled from open wells around the Iddo area of southwestern Nigeria. The water quality and usability were determined and the possible pollutants in both rainy and dry seasons were ascertained. The quality of water in this area is of good for domestic and industrial purposes as it is within the acceptable limit of World Health Organization standard.

1. Environmental impact assessment around Lokoja – Abuja environments, northwestern Nigeria (Bida Basin). This work presented the evaluation and emphasizes on the absorption rate and impacts of elemental concentrations in waters, soils and plants as it affects the environment and health in the study area.

In Progress

1. Calcareous nannofossil biostratigraphic evaluation of the Anambra, Benue Trough and Sokoto Basins is in continuation with the work done in Niger Delta. This aim is to erect the major and minor nanno-zones base on the fossil assemblage recovery.

1. The Cretaceous – Tertiary boundary investigation of the Nigeria Sedimentary inland basins. This involves detailed studies on exploratory well samples on the evidences of the events at the Cretaceous – Tertiary (K-T) boundary and its effect on fauna and flora extinctions in Nigeria. The K-T boundary shall be defined via lithological and palaeontological changes as well as the K-T iridium anomaly.

1. The West African Quaternary palaeoclimatic/sea level changes were research based on the evidences from marine and terrestrial sources. This was initiated by the International Quaternary Association (INQUA) in 2010 under the West African Quaternary Research (WAQUA) which was inaugurated in the same year. This work is a multi-field and institutional scientific research to examine the environmental impacts and socio-economic potential climate changes in West African coastal region.

1. Isotope records of palaeoclimate changes in Quaternary sediments of southwestern Dahomey Basin. This involves the use of stable isotopes in understanding the provenance, environment of deposition, age of the sediments and palaeotemperature changes that prevailed during the emplacement of the sediments.
