ABSTRACT Facies geometry, stratigraphic configuration, structural style, hydrocarbon type and distribution within the paralic Agbada Formation of Middle to Late Miocene age across several fields in the Eastern part of the Coastal Swamp depo-belt were studied using regional 3D seismic, wire-line well logs and biostratigraphic data. The study involved analyses of sequence stratigraphic framework across nine fields using information obtained from twenty- four wells. Ten major stratigraphic bou...
ABSTRACT Cenozoic sediments outcrop in the Niger Delta Basin. Deposits in the Basin thicken southward (down-dip) but thin northward (up-dip) around Bende – Umuahia area where approximately 260 m thick exposure was logged from base to top. Sieve analysis and petrography were carried out to establish the depositional settings of sediments while palynological analysis was undertaken in order to identify palynomorphs and establish their biozonations, determine and correlate age of sediments, as...
ABSTRACT This research work presents findings of the extent and distributions of saline zone and the hydrochemical characteristics of the groundwater of Awe, Keana and Giza areas in the Middle Benue Trough of Nigeria.Staticwater levels(swl) of hand dug wells were measured andthe results used to generate hydraulic head data and hydraulichead map. The static water levels range from 1.0m to 13.5m at Awe, 1.0m to 4.5m at Keana and 2.2m to 9.2m at Giza. The hydraulic head maps for the three areas ...
ABSTRACT The role of water in petroleum migration has hitherto been grossly underplayed because of the unsuccessful search for a model that demonstrates the movement of water and hydrocarbons combined in a single phase, It appears, however, that many of the alternative mechanisms that have been favoured also require the availability and movement of large quantities of water at great depths for their efficiency. For example in models that favour continuous oil phase during migration, excessive...

ABSTRACT The Nanka Sand (~ocene, Ypresian Stage) is one of the several lithostratigraphic units comprising the lithic fill of the Anambra Basin, southeastern Nigeria. Its unitstratotype has been selected from a system of gullies in the Nanka town. Here the unit is 305 metres thick and is underlain by the Imo Shale and, farther southwest, overlain by the Ogwashi-Asaba Formation. The stratigraphic column may be divided into four cross-bedded and burrowed tabular sand subunits ranging from 50 to...
ABSTRACT Ground magnetics and electromagnetic datasets were processed to interpret the subsurface geology and structure of the southwest of Ghana within the Tarkwain and Volcanics in the central part of the Ashanti belt. The study was aimed at mapping lithology, delineating structural lineaments and their trends as well as the trend of mineralization in the study areas. The data processing steps involved enhancement filters such as reduction to the pole, analytical signal, the first horizont...
ABSTRACT A 3D seismic data merged with a regional 2D seismic data and well data acquired from Ghana National Petroleum Corporation were used to determine the tectonic impact on regional structural trend in the Ultra-Deep Water Cape Three Points. The Cape Three Point basin was fashioned from transform tectonic and has been severely influenced by the largest tectonic feature in the central Atlantic Ocean, the west-southwest – east-northeast (WSW-ENE) romanche fracture zone. The study area li...
ABSTRACT An investigation was carried out on the groundwater potentials and aquifer protective capacity of Ishiagu area, southeastern Nigeria. The study area lies within the lower Benue trough of Nigeria and is underlain by the Albian Asu River Group and the Turonian Ezeaku Shales.The methodologies employed in the study include measurements of static water levels of 15 hand dug wells, pumping tests carried out on 4 boreholes and vertical electrical sounding (VES) of 20 stations. Groundwater p...

ABSTRACT This Research examines the heavy metal distribution of a dumpsite in Uvwie Local Government Area along Warri Port Express-Way of Delta State Nigeria. A total of eight (8) soil samples and (2)-plant sample were collected from the study area and also control site using a systematic sampling technique. Samples were taken to the lab and analyzed to determine the physicochemical parameters and heavy metal content. The dumpsite is contaminated with heavy metals such as iron (ranging from...
ABSTRACT The Maastrichian-Paleocene sediments in Yuli area me composed of the Gombe Sandstone and the Kerri-Kerri Formation. They cover 400 square kilometres have a thickness of more than 100 metres. Six stratigraphic sections were studied, representing the entire stratigraphic succession of the Gombe Sandstone in the Yuli area, The formation has a thickness of about 30 metres in the studied area. The Gombe Sandstone consists of folded beds of sandstone, siltstone and mudstone. The sandstone ...
ABSTRACT of the electrical resistivity technique, which red to the seismic technique in fault seal . .. ., ....... . . . , The Agu Abor fault is a prominent growth fault that provides insights on the processes of clay smearing at the fault zone. The properties of the sheared zone in the Cretaceous Enugu Shale were investigated to evaluate the dimensions of the fault, by the use is a cheaper method when compa study. The methodology used for evaruaang tnese possltmtles Involves tne resistivity...
ABSTRACT The present study area is bound within the latitude of 5055” N to 6° 0’ 0” N and longitude of 7055” E to 8° 1’ 0” E in the Southern Benue Trough, within the Afikpo syncline and Abakaliki anticlinorium, in south eastern Nigeria. The shale unit underlie the bioturbated sandstone unit. Sedimentary structures were also observed in the study area, which include tabular cross stratification, beddings, herribone structures, asymmetrical ripples and trough cross beds. Asymmetri...
ABSTRACT Geotechnical evaluation of sub grade and subbase materials from Redemption camp and Igbesa and Ijuri area within the sedimentary terrain of Eastern Dahomey basin of South-Western Nigeria were analyzed for their physical and engineering properties required for construction purposes. Total of 13 soil samples were taken, 6 from the location Redemption Camp and 7 from Igbesa and Ijuri area for analysis. The physical characteristics such as Grain Size, Specific Gravity, Moisture Content,...
