DETERMINATION OF AQUIFER CHARACTERITICS IN ITEM AREA OF SOUTHEASTERN NIGERIA

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 param...

INTEGRATED LANDSAT-ETM+ AND AEROMAGNETIC STUDY FOR ENHANCED STRUCTURAL AND GEOTHERMAL INTERPRETATION: CASE STUDY OF PART OF CALABAR FLANK, NIGERIA

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 bot...

DELINEATION OF SALTWATER INTRUSION ZONE IN PARTS EASTERN OF NIGER DELTA USING RESISTIVITY AND GEOCHEMICAL DATA

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 configurati...
