چکیده
Geochemical analysis of sediments recovered from NS-1 well and NS-2 well, Leuma Field, Coastal Swamp Depobelt, Niger Delta Basin was done to establish tectonic setting provenance. Data for ten major elements forty-three trace were obtained two boreholes. The geochemical signals display systematic stratigraphic trends in the wells that depict one source terrain. To determine provenance sediments, Th/Co vs La/Sc plot utilized which inferred derived felsic rocks. TiO2 versus Ni bivariate also used it revealed penetrated by is predominantly acidic nature. further confirmed considering ratios Thorium/Scandium (Th/Sc), Thorium/Cobalt (Th/Co), Chromium/Thorium (Cr/Th) Lanthanum/Scandium (La/Sc). For (Th/Sc) range 1.12-2.01, (Th/Co) 0.91-1.66, 4.21-16.04 (La/Sc) 3.69-8.78. 0.95-2.05, (Thko/Co) 0.94-1.91, (Th/Cr) 4.32-15.43 2.58-6.66. These values transported rocks.Inorganic results infer facies passive continental margin.

Polycyclic aromatic hydrocarbons in sediments and soils from oil exploration areas of the Niger Delta, Nigeria.
The distribution of polycyclic aromatic hydrocarbons (PAHs) in sediments from rivers and canals adjoining some oil exploration sites in the Niger Delta and surface soils from host communities were examined. The concentrations of 28 target PAHs ranged from 65 to 331 ng/g (average: 168 ng/g) and from 24 to 120 ng/g (average: 80 ng/g) in the sediment and soil samples, respectively. Two-ring PAHs w...
متن کاملPetrography, Mineralogy and Geochemistry of Kuhkamar Shale in the Roum section (South of Qayen): Application for Provenance and Tectonic setting
The Kuhkamar shale with a thickness of 354 m is composed of siliciclastic rocks (sandstone and shale). Petrography studies of the sandstones in this area show two petrofacies including arkose and sub-arkose. These sandstones composed of sub rounded to moderately sorted; therefore, compositionaly to texturaly, they are immature to submature with mono and polycrystalline quartz and k-feldespar. I...

متن کاملEvaluation of Geopressure Regime in an Onshore Niger Delta Field of Nigeria
Geopressure evaluation or prediction is an important exercise that must be carefully estimated when planning a drilling campaign. Formations of high pressure regime can be experienced in several areas within the bore hole depths. Being unaware of these areas that experience high pressure regime can create many uncontrolled events such as blow outs that may lead to human and material loss within...
