Petrophysical well logs were integrated in an analysis for the reservoir characterization of C and D wells located in the Offshore Depobelt of the Niger Delta Basin, Nigeria. The study essentially determined reservoir properties such as Lithology, shale volume, Porosity, hydrocarbon saturation and Net-Gross from Well logs with a view to determining the Reservoir quality. Two lithologies were identified using Gamma ray and Resistivity logs which were sand and shale but minor presence of carb...
________________________________(Received: 08:03:2017; Accepted: 05:04:2017) _______________________ Abstract Lipase from Aspergillus flavus was purified in a single step purification using MnFeO4 magnetic nano particles to achieve a 20.53- fold purification with specific activity of 11.29 U/mg and a 59% recovery yield. SDS-PAGE of lipase showed a single pure band with corresponding molecular weight of 35 kDa. The optimal temperature and pH for the enzyme activity were 45°C and 7.0 respe...
The purpose of the research is to determine the impact of Technology Based Self-Service Banking (TBSSB) on customers’ satisfaction in the Banking Sector of Nigeria. Focus is given to five selected banks within Jimeta and Yola, in Adamawa state. The research determines the relationship among relevance, impact of speed of delivery, convenience, efficiency, reliability & security as well as their influence on customer satisfaction. The relevance attribute impact of the predictor construct on e...
This paper investigates the efficacy of the shooting method and finite difference method in the numerical solution of two point boundary value non linear problems. The difficulty in providing exact solutions to two point boundary value problems via analytical methods necessitated the study. The shooting method which utilizes the Runge-Kutta method as integrator provides us with a better approximation to the solution than the finite difference method which utilizes second order, central differ...
The novel approach of unraveling the potential of bypassed hydrocarbon reservoir a thinly laminated geology by comparing the petrophysical parameters and computed Stock Oil Initial-in-Place (STOIIP) obtained from conventional log response to that obtainable in high resolution image data sets was carefully initiated. Archie's equation was adopted in the estimation of water saturation. The net-to-gross was estimated directly from the logs. TECHLOG 2.7 Version was used to estimate the pefrophys...

- Elections are the bedrock of democracy and voting is one of the electoral processes that ensure the sustenance of democracy, political growth and democratic stability of any society. We have designed an Enhanced Electronic Voting System (EnEVoS) with a Hybrid Authentication Technique, which will reduce electoral malpractices and manipulation of results to its barest minimum. The implementation of this Enhanced Electronic Voting System (EnEVoS) in Nigeria will boost the integrity and image o...
The work is on the distribution pattern of filling station in Benin metropolis, it also shows the conformity of filling stations in regards to the rules and regulations of the DPR (Department of Petroleum Resources) in Nigeria.
In this research work, we have reviewed and studied two disease models: a disease model with logistic recruitment rate with and without incubation period and a disease model with linear recruitment rate with and without incubation period. The existence and stability or otherwise of the equilibrium states of the models were studied; also numerical experiments were conducted using a written computer program in MATLAB function ode45; for which table of parameter values were generated using sec...
Abstract One major environmental hazard causing serious social problem in oil producing communities in Niger Delta is oil spills. This is as a result of the numerous petroleum related installations. T he the aquifer via pathways along which contaminants flow from the surface to th deterioration of water quality in shallow and vulnerable aquife rs spills contaminate e aquifer causing . Electrical resistivity investigation of the SombreiroWarri Deltaic Plain deposits of the Niger Delta was carr...

ABSTRACT Ditch cutting samples collected from interval 2590 3300 metres in Well K-27, Greater Ughelli depobelt, Niger Delta were studied for their lithology and foraminiferal content with the aim of dating and subdivision of the sequences penetrated by the well into biozones. The samples were processed using standard foraminiferal processing methods involving sample disaggregation and washing through a 63 micron mesh sieve, drying and picking and subsequent analysis of the foraminifera and a...

Department of Geology, Gombe State University, Gombe, Nigeria (Sabbatical), 2. Department of Geology, University of Calabar, Calabar, Nigeria ABSTRACT Seismic and checkshot data, geophysical data and biostratigraphic data extracted from ditch cutting samples, were used for the sequence stratigraphic analysis of Beta-24 we...
ABSTRACT Bio-fuels are prominent in current discussions both as a solution to problems and as a creator of problems. They have promise as a substitute for fossil fuels, particularly petroleum as the raw material for transportation fuel. But bio-fuels also have pitfalls, especially when produced at a scale sufficient to replace a significant proportion of the world's use of petroleum. This controversial topic has attracted great political, economic and social attention because of its touching...
