Abstract Although magmatism may occur during the earliest stages of continental rifting, its role in strain accommodation remains weakly constrained by largely 2-D studies. We analyze seismicity data from a 13 month, 39-station broadband seismic array to determine the role of magma intrusion on state-of-stress and strain localization, and their along-strike variations. Precise earthquake locations using cluster analyses and a new 3-D velocity model reveal lower crustal earthquakes beneath th...
Abstract Leveling is a branch of surveying and one of its targets to find out the topography of earth surface, more over it is required in the setting out of all kinds of engineering works. Creation of Dry ports are to help costal ports and they need to be interconnecting by road and rail infrastructure. Planning and design of Dry ports as large area are looks like container ports at system and aspects. Apprehensible of interpolation deals with knowing or telling what is going to happen, o...
Dealt with the subject of the study through spatial distribution of the governmental health centers, for understanding its relationship with the numbersof population, health outcomes and access, in light of rapid urbanization worldwide. The crisis in the health sector of Sudan has seen very obvious since the last decade, particularly in Bahri locality. It turns out the requires of appropriate infrastructure because of lack of attention to proper and suitable planning for the distribut...
ABSTRACT In the Buntsandstein gas fields of the Southern North Sea, the Volpriehausen reservoir is the main producing unit. This reservoir suffers often from the in-filling of the reservoir pore spaces by solid materials (salt plugs). Determining the reservoir quality of these fields based on seismic data alone has proved to be a major exploration challenge; the presence of salt-plugs in reservoir pore spaces seems to produce seismic responses that are similar at first sight to that of gas-f...
ABSTRACT Oil spills have become a major environmental hazard constituting serious social problems in Nigeria, especially in the oil producing communities. The geoelectric technique of geophysical investigation has been used to evaluate possible pollution of the groundwater by hydrocarbon as a result of oil spills in six oil producing communities comprising of Olch, Olomoro, Uzere, Aficsere, Ekakpamre and Uvwiamuge within the western Niger Delta. A total of one hundred and thirty nine vertical...
ABSTRACT Hydro-geophysical study of Mbano and environs, Southeastern Nigeria was carried out with the objective of estimating aquifer hydraulic parameters from resistivity data. Thirty-six (36) vertical electrical resistivity (VES) sounding data using the Schlumberger array were acquired with a maximum current electrode spread of 1000m using the ABEM Terrameter SAS 4000. Out of the thirty-six (36) VES soundings, fourteen (14) parametric soundings were carried out at the locations of existin...
ABSTRACT Structural interpretation of Younger Granite complex of northern Nigeria using aeromagnetic and Landsat imagery was carried out to determine the depth to the magnetic basement, delineate the basement morphology and relief, delineate the structural features associated with the basin and to infer the influence of such structures on mineralization in the study area. Also, this study is aimed at determining the geothermal potentials of the area. The application of directional edge...

ABSTRACT Fault seal analysis in fault dependent reservoirs were carried out at different reservoir levels in the Baka Field, Niger Delta. These involved stratigraphic correlation, 3-D seismic interpretation of faults and horizons, time-depth conversion of all interpreted faults and structural maps using both check-shot and synthetic seismogram. Also, static models of all interpreted reservoir levels, and 3-D deterministic and stochastic fault seal integrity models were carried out. The deter...
ABSTRACT The thrust of the study which carried out in the Cenozoic Niger Delta is to infer and predict potential Petrophysical properties and hydrocarbon presence in unexplored areas proximal to producing areas in the eastern flank of Cenozoic Niger Delta, Nigeria, using seismic data and analogue proximal well data set from a producing area for subsurface reservoir characterization. Seismic and offset well dataset were used as input dataset to carry out Petrophysical evaluation, Seismic int...
ABSTRACT Interpretation of structures and reservoir characterization using 3D seismic cube and well data pose great challenges in mapping because of their complexities especially in structural deformations, and where identification of reservoir facies is a major challenge to plan delineation, field appraisal and development drilling. Thus, the project work takes a model approach. The ―DIBA‖ Field in the Niger Delta contains hydrocarbons that are largely trapped in sandstones and unconsol...
ABSTRACT An integrated seismic interpretation using 3-D seismic data, check shot data and a suite of well logs for four wells were analyzed with the Petrel (seismic to simulation software). The objectives were to carry out a detailed formation evaluation, reservoir characterisation and a 3-D assisted structural interpretation of the densely faulted oil field in the coastal depo-belt of the Niger Delta. RMS amplitude, instantaneous frequency map and interval average extraction maps were ext...
ABSTRACT Hydro-Geo-electrical study of subsurface geology of Item area, South-eastern Nigeria has been carried out involving twenty-four Vertical Electrical Sounding (VES) of which the schlumberger electrode configuration was employed for the field data acquisition. A maximum of half the current electrode separation (AB/2) of 1000m was used. The VES data were interpreted using conventional partial curve matching method to obtain initial model parameters while the computer iterative modell...
ABSTRACT An integrated structural interpretation of part of the Calabar Flank and environs was carried out using high resolution aeromagnetic (HRAM) and Landsat-ETM+ data to study magnetic basement depth, structure and tectonics of the study area. It is believed that result of this study will help in making far reaching inferences of the hydrocarbon and geothermal potentials of the study area. Several image processing and analytical techniques were applied to both the aeromagnetic and Lan...
ABSTRACT Detailed hydro -geophysical and hydro-geochemical studies were carried out in part of the Niger Delta Basin Nigeria. The objectives were to map and provide evidences that the coastal aquifers in the study area have been intruded by saltwater and to establish analytical/empirical relationships between resistivity and geochemical parameters. Twenty three vertical electrical sounding (VES) data employing the Schlumberger electrode configuration were acquired in different parts of th...
