Sequence Stratigraphic Interpretation of XY-Field Onshore Niger Delta Basin Nigeria.
(University of Port Harcourt in Nigeria., 2021-10) OKPALA, C. E.; OSISANYA, O. W.; IGHRAKPATA, F. C.; SALEH, A. S.; IBITOYE, T. A.
Wireline logs and biostratigraphic data were integrated to attempt the sequence stratigraphy of “XY field” onshore Niger Delta Basin which revealed three epositional sequences. Four sequence boundaries and three maximum flooding surfaces dated (17.7, 16.7, 15.5, and 13.1Ma) and (17.4, 15.9, 15.0 Ma) respectively were identified in both Wells. The delineated sequences comprised Lowstand Systems Tracts (LST), Transgressive Systems Tracts (TST) and Highstand Systems Tracts (HST), which reflect depositional systems deposited during different phases of base level changes. The sands of LST and HST show good reservoir qualities while the shales of the TSTs could form potential reservoir seals. Integration of lithofacies and biofacies data suggests that the depositional environments ranges from transitional to Outer Neritic environment.

The application of the VES geophysical technique to investigate groundwater potential and the aquifer vulnerability was carried out at Akure, southwestern part of Nigeria. Sixteen (16) VES points were selected using a Schlumberger array applied for the conduction of the VES. The ABEM Terrameter SAS 1000 was used and the maximum current electrode spacing (AB/2) was 100 m. A partial curve matching technique and computer iteration technique were applied in the interpretation of data using WINRESIST software, while Groundwater Modeling System (GMS) software was used to model the groundwater flow direction. The study revealed the presence of two to four layers of curve types, which include H (69%), HKH (19%), A (6%), and QH (6%) respectively. The second-order geoelectric parameters include longitudinal conductance (S), average transverse resistance (Tr), average longitudinal resistance (ρL), coefficient of anisotropy (λ), reflection coefficient (Rc), and resistivity contrast (Fc). The estimated aforementioned parameters range 0.004–1.03, 659.6–12,416.6 Ω/m2, 28.21–267.4 Ω-m, 58.82–303.26, 1–1.5, 0.33–0.97, and 2.01–57.33, respectively. The distributions of these parameters are revealed by the contour maps, which aid in the delineation of zones with different layer characteristics. The findings of this study can be used as a guide for making decisions on groundwater abstraction and management.
Effects of Reservoir Angle on Vertical Well Performance.
(International Standards Publication., 2023) Maurice, Akpan B.; Osisanya, Olajuwon W.; Ogugu, Augustine A.; Onyekwere, Kelechi R.
Petroleum engineers are desperately needed to maintain sustained clean oil production for a long time without running into flow restrictions caused by external boundaries. These boundaries could take the shape of sealing faults, which are the most frequent in real-world situations, constant-pressure boundaries, or other reservoir heterogeneities, such as fractures, layers, and lateral discontinuities, to name a few. This study aims to examine the impact of reservoir angle on the efficiency of vertical oil wells. In this study, empirical mathematical models were used to describe vertical oil wells constrained by two sealing faults in a
reservoir supported by a strong aquifer. The mathematical models developed by (1) are applied by computer software. It was determined after evaluation that lower reservoir angles provide greater values of pressure derivatives, which is indicative of good productivity and performance. To evaluate the impact of the reservoir angle on dimensionless pressure and pressure derivatives, a sensitivity analysis was also conducted utilizing a fixed value of dimensionless time to study various reservoir angle values. However, it was shown that the dimensionless pressure, PD, is unaffected by the reservoir angle. The dimensionless pressure derivative (P'D) was shown to have an inverse relationship with the reservoir angles. To verify the accuracy of the results, a comparison analysis between the findings from the constructed computer model, OBLIQ, and those found in the literature was carried out. The analysis' findings demonstrated that the study's finding is consistent with those in the literature.
An Integration of Geophysics and Petrophysics in Study of Rock at Elete, Lokoja Southwestern Nigeria.
(European Centre for Research Training and Development -UK, 2023) Shaibu, Ojoka B.; Osisanya, O. Wasiu; Saleh, A. Saleh; Asarhasa, E. Peter; Okpala, Emeka C.
Granitic Gneiss and Banded Gneiss make up the bulk of the local rock types, and quartz veins are the most common intrusions seen there. Tectonic upheavals in the earth's crust are responsible for the region's structural features, including as foliations, folds, joints, and fissures. The goal of this research is to integrate several scientific techniques to subsurface structure definition. For this study, 16 Vertical Electrical Sounding (VES), petrophysical study, and background knowledge of geology were used to delineate subsurface rock. The Schlumberger array with a maximum electrode separation of 300m was employed for VES. Elete's true aquifer resistivity map shows that the South-Eastern and North-Eastern axis has relatively low resistivity values, which may indicate the presence of an aquiferous zone, while the North-Central and Southern regions have a wider range of resistivity values, which may not be consistent with a water-bearing zone. Additionally, petrographic analysis of the rock reveals that the mineral composition of Granitic Gneiss is Quartz (41.72%), Plagioclase (10.79%), Biotite (25.17%), Muscovite (19.42%), and Opaque (2.87%). While biotite makes up the granite gneiss. Biotite (45%), Muscovite (9.93%), Quartz (36.87%), Plagioclase (4.26%), and Opaque (3. 55%).Hydrogeologically, it stands to reason that Elete and its surroundings are situated in a region with medium to good groundwater potential based on the information at hand and the results of the geophysical investigation.
Weathered/fractured basements are anticipated to contain productive aquifers.
Learning for Development, Skill Acquisition and Change Management: A Panacea for Emerging Technologies and Infopreneurship.

All over the world, due to rapidly developing technologies, 21st-century organisations and institutions are striving for innovation, cost minimisation, autonomy, and competitive intelligence to stay ahead of their contemporaries. Amongst these institutions, academic libraries are the most pressed to explore all avenues to ensure substantial changes are used to meet the needs of library users and their immediate communities. This paper, therefore, highlights certain skills and
competencies that will enhance contemporary practices and trends in academic libraries. This paper aims to guide the significance of learning and development in academic libraries. As a crucial component of academic libraries, the necessity for librarians to practice infrorepreneurship will also be discussed in this presentation. Additionally, the paper will examine the function of libraries and the arrival of various contemporary technologies in academic libraries. This article
seeks to highlight the importance of learning and development opportunities for library staff members’ employability, job retention, and digital competency. The recommendations regarding the need to investigate these ideas and insights to promote them to popular information services are supposed to be utilised by librarians and information professionals. Therefore, the paper's conclusion will highlight the necessity for librarians to update their digital literacy skills, develop
competence in performing their tasks, and enhance their role in academic institutions.
