ABSTRACT The evaluation of sandstone properties in parts of the Anambra Basin was undertaken to identify the spatial distribution of textural, petrophysical and mineralogical properties of sandstone bodies in the area in order to assess their potentials to host hydrocarbons. Sandstone units from Nkporo Formation, Mamu Formation, Ajali Sandstone and Umuna Sandstone were subjected to textural analysis using sediment granulometry, thin-section petrography and geochemical analysis. Following the...
ABSTRACT The study is on the characterization and depositional environment of upper Cretaceous sediments exposed at the Ihube-Ikpankwu Axis, Okigwe. The results of field and laboratory studies on selected samples of the study area show that the sediments in the study area are fine to medium grained, with an average mean size of 1.808Φ. The standard deviation (dispersion sorting) values range from 1.38 – 2.48 i.e. poorly to moderately sorted with an average value of 1.805Φ. The studied sa...
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 boun...
