The Hydraulic Characteristics Of Mbano And Environs, Imo River Basin, Nigeria Using Geoelectric Data

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 exi...

Interpretation Of Aeromagnetic And Landsatetm+ Data Over Part Of The Younger Granite Complex, Nigeria: Implication For Geothermal Exploration

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 ...

Application Of Deterministic And Stochastic Analysis Of Fault Seal Integrity In Baka Field, Niger Delta.

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 ...

3d Seismic Interpretation Of Shallow Marine In “Dabra Area” Offshore Niger Delta

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...

3-D Seismic Attributes Analysis And Reserve Estimation Of “Guramala Field”, Coastal Swamp Depobelt, Niger Delta.

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 ...

Geophysical Investigation For Groundwater Potential Evaluation Of A Regolith Aquifer In A Typical Basement Complex Terrain; A Case Study Of Ikole Ekiti, Southwestern, Nigeria.

ABSTRACTA geophysical investigation involving the electrical resistivity method was carried out atIkoleEkiti of South Western, Nigeria with the main aim of investigating the area forgroundwater potential of the regolith aquifer.The objectives are to identify geological structures and aquifers favorable to groundwateraccumulation andalso input geoelectric layers parameters into a software to produce maps ofthe subsurface in order todetermine the groundwater potential of the regolith aqui...

Geo-Electric Soundings For Groundwater Exploration In Part Of Port Harcourt, Rivers State, South-Eastern Nigeria

ABSTRACTGroundwater is the water that exists in pore spaces and fractures in rocks and sedimentsbeneath the water table. The need for groundwater has increased tremendously due to theunavailability and the contamination of surface water bodies by the intrusion of saline water andhuman activities.· The geo-electric soundings were carried out in Eleme Port Harcourt, capital of Riversstate in order to delineate the subsurface geo-electric layers and the depth to the aquifer unit forg...

Integrated Geophysics Methods For Post Foundation Student Phase One, Faculty Of Social Science And Humanities, Federal University Oye Ekiti, Ekiti State

ABSTRACTA combined geophysical method involving very low electromagnetic method. magnetics and electrical resistivity methods were used in delineating the causes of crack in the building at Faculty of social Science and Humanities Oye Ekiti, Ekiti, State. Five (5) VLF-EM traverses were established in both east-west direction and also north-south direction were occupied in the building and Twenty-one (21) VES studies were also occupied around the building. The VLF...

Fault-magma interactions during early continental rifting: Seismicity of the Magadi-Natron-Manyara basins, Africa

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...

Interpolation Of Spot Heights In Seloum Dry Port

AbstractLeveling 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,...

Primary Health Service Distribution in Urban Areas Using GIS

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 pla...

Influence Of Solid Pore Fills On Reservoir Characterization Studies Calibrated On The Triassic Volpriehausen Formation, Southern North Sea Basin

ABSTRACTIn the Buntsandstein gas fields of the Southern North Sea, the Volpriehausen reservoir is themain producing unit. This reservoir suffers often from the in-filling of the reservoir pore spacesby solid materials (salt plugs). Determining the reservoir quality of these fields based on seismicdata alone has proved to be a major exploration challenge; the presence of salt-plugs in reservoirpore spaces seems to produce seismic responses that are similar at first sight to that of gas-fi...

Geoelectric Mapping Of Hydrocarbon Contamination And Characterization Of Ground Water Protective Layers In Parts Of The Western Niger Delta,Nigeria

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...
