ABSTRACT A geophysical well log plotter manager was developed using visual studio .net version 7.0 software in order to address the challenges faced by researchers within the academic cycle in converting digital well log data to well log curves so as to facilitate qualitative well log interpretation. The plotter was used to plot well log […]
ABSTRACT Detection and estimation of overpressure using well data have been attempted. Suites of logs from three wells in the overpressured oil fields of the Niger Delta were used. Using the formation pressure information, the hydrostatic pressures of the three wells were derived. Working intervals were carefully selected from the same lithology (shale) within the […]
ABSTRACT Concurrency control issues like the “isle-of-March” has come but not gone. It is not surprising that several models designed to handle concurrency control in databases; there still exist some overheads in transactional database controls. One of such problems is the incompletion of the execution of necessary codes within the critical region of a lock […]
ABSTRACT Pores are all openings found in a rock. Some rocks have simple while others have complex pore systems. Most sandstone reservoirs are typically single-porosity systems of relatively homogeneous in nature. Carbonate reservoirs commonly have multiple-porosity systems. They are often complex and heterogeneous nature. Today, one of the most pressing problems of petroleum production from […]
ABSTRACT The West African manatee (Trichechus senegalensis) has great potentials for ecotourism. It is however threatened with extinction in Enion Creek due to excessive exploitation resulting from the high commercial value of its meat, oil, skin and bone. Anthropogenic perturbations, socio-economic indices and awareness level of the local people about conservation and their impact on […]
ABSTRACT The leaves of phymatodes scolopendria was analysed for proximate, mineral, toxicant and phytochemical compositions. The proximate analysis showed that these leaves contained 20.40± 0.34% moisture, 14.00 ± 0.12% ash, 4.60 ± 46% crude lipid, 8.80 ± 0.10% crude fibre, 12.60 ± 0.20% crude protein, 68.80 ± 0.32% available carbohydrate and energy value of 366.8 […]
ABSTRACT Time-lapse seismic amplitude analysis were carried out on HD2000 reservoir located in the land/swampy field of Nembe creek, Niger Delta by integrating AVO modeling from well and horizon attribute analysis from 4D seismic. The aim of the study was to monitor water flooding, map reservoir compartmentalization, and detect by-passed oil zones. Initial fluid sensitivity […]
ABSTRACT One of the problems facing users of the University Library is the location of shelves were their required books are stored. This is because the shelf marks that are used to identify book shelves in the library consist of confusing sequences. The current guide for users to locate book shelves are notices placed on […]
ABSTRACT An algorithm to locate the global minimum of the alias matrix for the biased response function has been developed. The algorithm begins by classifying all the support points into experimental region of interest, then starting from an arbitrary set of N support points, the algorithm obtains an N – point optimal design by systematically […]
ABSTRACT Mobile cell phone menu and sub menu designs are central to the utility derived by users when interacting with the phone; a bad design would often result in poor usability and vice versa. In this paper, I have chosen to study and understand how the user interacts with a cell phone contact menu and […]
