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...

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 exis...

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....

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, S...

3d Seismic Interpretation And Reservoir Characterization Of “Diba Field’’, Niger Delta, Nigeria

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 an...

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...

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...
