Article
Full-text available
Background: Oloibiri is a community in Bayelsa State, in the Niger Delta region of Nigeria. The first commercial oil discovery in Nigeria was in the community. Oloibiri oilfield produced oil for 20 years and production finally stopped in 1978 and the field was abandoned. There was growing interest in identifying new petroleum prospects within Bayel...
Article
Full-text available
Background: Bayelsa State, Nigeria is located in the Niger Delta Basin. The basin is very rich in oil and gas. In November 2020, Bayelsa State hosted the National Council on Hydrocarbon Summit, where the government revealed its interest in identifying new petroleum prospects in the state. The growing interest in new hydrocarbon prospects by the gov...

Measurement of Natural Radioactivity in some Borehole Water in Ogbia Local Government Area, Bayelsa State, Nigeria was carried out using High Purity Germanium Detector. The aim was to identify the radionuclides present in the water samples with their respective concentration. The activity of 40 K ranged from 0.47±0.04 to 14.90±1.14BqL-1. The activi...
Article
Full-text available
The discovery of hydrocarbon in the areas bordering Afikpo Basin prompted the re-evaluation of the sedimentary thickness within the basin with high resolution geophysical data. Depth to magnetic sources, sediment thickness, basement topography and structures within it were investigated using spectral analysis, analytic signal and tilt derivative of...
Article
Full-text available
Aeromagnetic dataset over Ikot Ekpene and environs, Eastern Niger Delta Basin, was processed to compute the basement depth, Curie isotherm depth, geothermal gradient and heat flow within the area in order to investigate the depth to magnetic sources, geothermal prospect and the hydrocarbon potential of the place. The adopted computational method tr...
Article
Full-text available
In this study, the airborne radiometric data over Masufashi Area of Katsina State and Environs, Northwestern Nigeria were acquired, processed and gridded to generate the concentration maps of percentage Potassium, equivalent Thorium and equivalent Uranium in order to carry out the geologic mapping of the area. Additionally, the abundance ratios, U/...
Article
Full-text available
Evaluation of the part of Ife-Ilesha Schist Belt was done to define the structures, geology and map out alteration zones related to ore deposits. Datasets from airborne geophysical method proved vital for mapping geology and structures within Ondo extension of the Ife-Ilesha Schist Belt. The total magnetic intensity data covering the basement compl...
Article
Full-text available
The cause of foundation based structueral failure of some buildings in the premicises of Federal University Otuoke, Nigeria was investigated using electrical imaging technique and geotechnical test involving moisture content, bulk density, specific gravity, free swell and texture determinations. The apparent resistivity data collected with ABEM SAS...
Research
Full-text available
Analysis of high resolution aeromagnetic data was carried out to evaluate the basin geometry of the Southern Benue Trough, Anambra and Afikpo Basins. The total magnetic intensity data covering the area was processed and filtered using Upward Continuation and Source Parameter Imaging. The total magnetic intensity map shows that the field strength va...
Conference Paper
Full-text available
High resolution seismic method has recently been carried out in Otuoke and Its Environs with the aim of investigating the near surface geological structure and the determination of the lithology which is very crucial for infrastructural development. To achieve this, seismic tomography was used for the survey. The results revealed that, the thicknes...
Conference Paper
Variations in seismic P-wave velocity and depth resolution resulting from variations in subsurface water saturation were investigated in this study in order to determine the season of the year that gives the most reliable P-wave velocity and depth resolution of the subsurface in Zaria Area, Nigeria. A 2D seismic refraction tomography technique invo...

Book
The assumption that valley trends are predetermined by geotectonic phenomena stands in contrast to the assumption of valleys being solely caused by exogenic agents. A study was carried out to delineate the structures that favour valley formation in a basement terrain of Zaria, Nigeria, in order to address the controversy between geotectonic and exo...
Article
Full-text available
The study area is Zaria, located in the basement complex of northern Nigeria. The rock type forming the major part of the Zaria batholith is granite. This research work was carried out to compare the responses of seismic refraction tomography and resistivity tomography in the same geologic environment and under the same conditions. Hence, the choic...
Article
Full-text available
Subsurface compressibility of three built-up sites in Zaria metropolitan has been assessed in order to aid geotechnical and engineering works in the area. Zaria area falls within the Basement Complex terrain of northern Nigeria. Previous geology works in the area show that clay is part of its younger alluvium. Also, recent geophysical works in the...
Article
Full-text available
The dependence on boreholes and hand-dug wells for water is increasing rapidly in Zaria, Nigeria, because of the inability of Water Works Department in the area to meet the water consumption requirement of the people. Almost all the boreholes and wells in the area fail to yield during dry seasons due to drastic reduction in groundwater table. This...
Article
A geophysical study was carried out in the vicinity of two collapsed and concealed septic tanks to delineate the structures responsible for their failure. Two-dimensional resistivity and seismic refraction tomography data were collected along a profile laid across the septic tanks. The data were collected using ABEM Terrameter SAS 4000, aided with...
Article
Full-text available
This study was carried out to assess the foundation depths around a building site in Zaria area, northwestern Nigeria using electrical imaging technique. The affected structure is a three storey building leaning at relative rotational angle of about 5.5 0 and having severe foundation-based cracks. The site lies within the Basement Complex of northe...
Article
Full-text available
The causes of some arbitrary and sharp changes, within a short lateral distance, of some physical properties of the subsurface in Zaria area were investigated in this work. The research area is located within the Kubanni Valley which is characterized by a high concentration of valley networks. The study was carried out in the vicinity of a valley i...
Article
Full-text available
Spearman's formula for rank correlation analysis has been applied to shallow 2D seismic refraction tomogram and electrical resistivity tomogram to determine their extent of their reliability in the characterization of their lithological stratification. Four profiles were occupied for both the seismic and the electrical imaging techniques during the...
