ABSTRACT This study involves the understanding of the stratigraphic distribution of the area by integrating well logs, biostratigraphic data and seismic data to better define hydrocarbon reservoir distributions within the Middle to Late Miocene sediments in ‘’OGBO” Field Coastal swamp Depobelt of Niger Delta Basin. Sequence stratigraphic, geostatistical and structural analytical tool have been incorporated in this study, in order to achieve this. Based on the sequence stratigraphic stud...
The aquifer transmissivity and hydraulic conductivity values of Agbani Sandstone was investigated using different statistical and pumping test approaches developed by different authors. A total of three (3) boreholes was constructed during the time of this study and it was used to determine aquifer characteristics of Agbani Sandstone. The depths to water table vary from 80 - 120 m and the results of transmissivity (T) values obtained from various approaches varies from 0.883 to 2.855 m2h-1 fo...
The primary aim of this study is to indicate the seasonal variations of heavy metals in the soil within the Abandoned Onyeama Coal Mine. To examine the extent of heavy metals pollution, 45 soil samples were collected from different locations inside and outside Abandoned Onyeama Coal Mine during the rainy and dry seasons for one year. The level of toxic metals viz., Pb, Cu, Mn, Zn, Cd, Fe and Cr were analyzed using atomic absorption spectrophotometer. Majority of the samples were below the sta...
The protection of groundwater quality is a critical aspect of ecosystem preservation. Nutrient (NO3-N and PO4-P) and non-nutrient (temperature and pH) assessments were carried out to study the shallow groundwater quality of Enugu metropolis in Southeastern, Nigeria. The result reveals that NO3-N and PO4-P are the main factors that endanger shallow groundwater quality safety of the Enugu metropolis. Total nitrogen (TN) and total phosphorus (TP) concentrations were observed to vary across the e...
Groundwater is one of the most valuable natural resources,playing a fundamental role in human health and wellness, socioeconomic development, and ecosystem functioning. Being the elixir of life,water resources ensure the stability of the ecosystem and the status ofhuman health. Hydrogeochemical characteristics of thegroundwater/surface water in the Ozalla were investigated by analyzingseven groundwater/surface samples, using various statistical methodsand graphical approaches to identify fact...
ABSTRACT This is thesis was done based on the textural, mineralogical and mineral chemistry studies of arc rocks from the North Island of New Zealand. The rocks in the area are of two main groups: the Kiwitahi and Coromandel groups. Both the Coromandel group and Kiwitahi andesites are typically porphyritic with a phenocryst assemblage (20–60%) consisting of plagioclase + pyroxene + Fe –Ti-oxide in a granular groundmass rich in plagioclase laths and pyroxene microcrystals. The Kiwitahi sa...
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: Groundwater potential at Akpugo and environs in Nkanu West Local Government Area of Enugu State has been undertaken in order to determine the groundwater status in the area. It lies on latitudes 060 2010011N to 0602510011N and longitudes 0070 3410011 to 00703910011E with an areal extent of about 86.49km2, over three geological units. A total of Twenty-five (25) vertical electrical sounding (VES) were acquired to determine the groundwater potential of the study area. Contour variatio...
ABSTRACT: An intensive field mapping covering a total of nineteen locations was carried on. This study aimed at determining the geology and depositional environments of sandstone deposited within Awkunanaw and environs in Enugu area. Based on litho-facies the study area is underlain by five lithological units. Integrated granometric (textural analysis) was carried out on eight (8) friable sandstone samples collected from two locations based on their stratigraphic positions. An application of...
Abstract The lithofacies and foraminiferal assemblages of the Imo Formation exposed at Umuna-Umuawo, Ezeagu, Anambra Basin were evaluated for the purpose of environmental interpretation and age dating. Lithofacies were described based on lithology. The lithologic units of the succession are basically dark-grey to bluish-grey shales with presence of gastropod mineralized shells depicting a marine depositional environment. The shale is interbedded with patches of siltstone and clay beds. The me...
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 Geo-environmental hazards associated with active and abandoned borrow pits are on the increase following rising trend in road construction. This situation presents a major challenge to Citizens, Environmentalists and Governments. Several highway failures have been directly linked to the action of erosion initiated by active or abandoned borrow pits situated close to roads. This study investigated environmental hazards and reclamation requirements associated with abandoned borrow pit...
