Abstract: The geology of Gulani area is composed of Precambrian basement complex of the Older Granite suit (diorite and granites), the Cretaceous sediments of Bima, Yolde and Pindiga Formations and the Tertiary/Quaternary basalts of the Biu Plateau. Epigenetic barite-copper mineralization with barite associated with sandstones and copper occurring in granites have been mapped in the area. Unaltered (distal), hydrothermally altered (proximal) host rocks and barite and chalcopyrite/malachite mineral separates were sampled and investigated petrographically and geochemically for their trace element abundances. Reflected light microscopy of the Cu-mineralized.........

Abstract: A possible cause of landslide is mining activity, with the problem exacerbated in areas where mining activities are uncontrolled and unregulated like the Jos-South, North-Central Nigeria. The aim of this study is to use 2-D electrical resistivity imaging as a preliminary tool to investigate landslide vulnerability of some tin mine sites in this area. The Wenner-Schlumberger configuration was used and the apparent resistivity (observed data) was iteratively subjected to inversion process using RES2DINV software, to generate the 2-D resistivity sections. The 2-D Electrical Resistivity models........

Abstract: Subsurface layers'velocity is very important in determining the depth, dip, and horizontal location of reflectors and refractors, for predicting velocities at various depth, time-depth conversion and calculation of sediment thickness in the subsurface and identification of structural closures for hydrocarbon exploration. The estimation of the subsurface velocity is a major challenge in exploration seismology. Accurate measurement of subsurface velocity has continued to receive great attention in the oil and gas industry. The seismic velocity- depth model was computed from check shot data from four exploratory wells in an onshore field in Niger Delta sedimentary basin. The velocity-depth model was obtained from computed surface velocity Vo and compaction factor k, for the medium.........

Abstract: Velocity analysis was conducted in, Agbada Field, onshore Niger Delta using geostatistical tools. This provided a quantitative technique of integrating interval velocities from Checkshots and Sonic Logs for 60 wells with the two-way travel time from 3-D pre-stacked seismic image data for an identified reservoir (D5.2). Analyses by crossplots, regression plot with variogram modelling, and kriging produced results useful in improving on some of the associated limitations arising from spatial data continuity, anisotropy and azimuthal properties inherent in velocity data.........

Abstract: Padhar Mafic Ultramafic (PMUM) suite of rocks comprises olivine pyroxenites, pyroxenites, gabbros and diorites. Olivine pyroxenites and pyroxenites forming the ultramafic component are mainly composed of olivine, clinopyroxenes, orthopyroxenes, as cumulus phase and phlogopite as intercummulus phase with ilmenite and magnetite as accessory minerals. Gabbros and diorites comprising the mafic component of suite are mainly composed of relict pyroxenes, amphiboles, plagioclases. Geochemically, on the TAS diagram the studied samples fall in tholeiitic field.........

Abstract: Porosity and permeability regimes in hydrocarbon-bearing reservoirs of Nembe Creek Field, Niger Delta were delineated by digitizing and correlating gamma ray, resistivity, and density logs from three wells: Nembe 01, Nembe 02 and Nembe 03 respectively. Results obtained from the analyses of these composite logs reveal eight potential hydrocarbon-bearing reservoirs. These reservoir sands were observed to have very good to excellent average porosities ranging from 29 to 45%. Permeability values were excellent within these reservoirs and range from 2200 to 5789mD..........

Abstract: The geo-electrical techniques involving the VES and 2-D resistivity imaging was used in assessing the groundwater quality of a coastal aquifer in Ogu-Bolo Local Government Area of Rivers State. This study used two Vertical Electrical Sounding data and three horizontal profiling data obtained using ABEM SAS 300B Terrameter. A computer modeling was used in processing the Data and partial curve matching was employed in the interpretation of the VES data. Five geoelectric layers of varying thicknesses, depth and resistivities were delineated. The fourth layer is where the best aquifer ranged from 41.70m to 42.90m at the various..........

Abstract: We used surface wave methods which includes single-station microtremor methods,Multichannel Analysis of Surface Waves (MASW), Refraction Microtremor(ReMi) for determining the shear wave velocity structure, which is important input parameter of ground and soil type definition in geotechnical earthquake analysis, and predominant period features of Bornova Plain (İzmir) and its surroundings in İzmir, Turkey. Engineering bedrock (Vs>760 m/s)depths are obtained in north and south parts of thestudy area. When compared, Vs values, predominant periods and geology are generally compatible.
