ABSTRACT Prospective evaluation of “XY” field in southwestern offshore Niger Delta was carried out with a view to delineate the structural and stratigraphic traps present in the study area. The research methodology involved horizon and fault mapping to produce subsurface structural maps. Attributes used to analyze the field under study includes: Variance time slice which was used to illuminates the main fault structure on the field and aid as guide to proper mapping. Similarly, this was ...
ABSTRACT Alaago-Alapoti area constitutes part of the Eestern Dahomey Basin of South-Western Nigeria and it is characterized by different formations. Samples were collected from this area and were subjected to the laboratory for test. Nine smaples were collected from Alaago-Alapo area, five hand-dug wells and four boreholes sampled and investigated in the persent study. This study characterises the physicchemical quality of ground water obtained from the hang-dug wells and boreholes. To get a...
ABSTRACT Laterites are soils that formed from the weathering of the basement complex and are rich in secondary oxides of Iron and Aluminum. It‟s red colouration is due to it‟s high iron content. Laterites are mostly found in Tropical regions which are characterized by distinct dry and wet seasons. Laterites are mainly used in the construction ofroads either as a subgrade or as a sub-base material. Geotechnical evaluation is one of the effective means of detecting and solving pre and post...
ABSTRACT Geo-electrical resistivity techniques are increasingly being applied in addressing a wide range of hydrological, environmental, and geotechnical problems. This is due to their effectiveness in near-surface characterization. Seven (7) vertical electrical soundings (VES) was integrated with 2-D geo-electrical resistivity in three locations and three traverses to characterize the near-surface and subsurface and also delineate the underlying aquifer properties in the sedimentary terrain...
ABSTRACT Electrical resistivity method involving the2-D surveying was carried out within the sedimentary complexterrain of Alapoti Ogun State South Western Nigeria with a view of estimating the geo electric layer parameters (resistivity and thickness),to identify the aquifer types and evaluate the ground water potential and over burden protective capacity over the aquifer.
ABSTRACT The need to increase the agricultural outputs is the major concern of the farmers in Ado-OdoIlaro District. Therefore there is need to determine the physico-chemical and geochemical parameters of groundwater and surface water within this sedimentary terrain in order to ascertain the quality of groundwater for agricultural purposes. Thirty-three underground water samples were collected for the determination of physical and chemical parameters. Sodium Adsorption Ratio (SAR), Soluble S...
ABSTRACT The environment is being degraded on a daily basis as a result of human activities like auto traffic, mining and agriculture among others. This has made environmental assessment studies and monitoring a matter of global attention considering our growing population Studies have also revealed that adverse health are associated with the pollution of the ecosystem by heavy metals which are easily bio accumulative but not biodegradable. This project is aimed at assessing the level of met...
ABSTRACT This study is aimed at determining the suitability of laterite soil derived from granite-gneiss from the burrow pit along Km 4 Ologuneru-Eleyele Road as a subgrade or subbase material Three samples were collected at different height from a burrow pit in the study area and were subjected to soil tests such as natural moisture content, optimum moisture content, maximum dry density, specific gravity and Atterberg limit at its dry state. Engineering tests such as California bearing rati...
ABSTRACT The study area, Ijesha-Ijebu falls within the Nigeria sector of the Eastern Dahomey Basin. It lies within the contact zone between the south-western basement rocks and the Eastern Dahomey Basin. The principal objective of this project work is to deduce the depositional environment and identify the formations in the study area. The field and laboratory investigation were carried out during this project work. Nineteen (19) rock samples collected were described for its: grain texture, ...
