Reservoir Characterization and Volumetric Analysis of Lona Field, Niger Delta, Using 3-D Seismic and Well Log Data

ABSTRACT  An integrated 3-D seismic data, checkshot data and a suite of four well log located at the Lona field, Niger Delta were analysed with Petrel software for reservoir characterization and volumetric analysis of the field. The method adopted involves petrophysical analysis, structural analysis, volumetric analysis and reservoir classification. Detailed petrophysical analysis revealed three reservoirs.Average reservoir parameters such as porosity (0.25), gross thickness (27 m), hydrocar...

Interpretation of High Resolution Aeromagnetic Data over Okigwe and some Adjoining Areas, South Eastern Nigeria.

ABSTRACT  Digitized high resolution total field aeromagnetic data over Okigwe and environ (Sheet 312) was interpreted using the standard 3-D Euler de-convolution and spectral analysis in order to determine depth to the magnetic basement, delineate the basement topography and relief, and delineate the trend of the structural features associated with the basin. The aeromagnetic data were subjected to various data enhancement and transformation routines using the Geosoft Oasis MontajTM software...

Fabrication and Capacitive (C-V) Characteristics of Conjugated Polymer Composite (P-PolyanilineN-Wo3) Heterojunction

Abstract A nanocrystalline and porous p-Polyaniline/n-WO3 dissimilar heterojunction at ambient temperature is reported. The high-quality and well-reproducible conjugated polymer composite films have been fabricated by oxidative polymerization of anilinium ion on predeposited WO3 thin film by chemical bath deposition (CBD). X-ray diffraction analysis of the deposited WO3 films revealed that as-deposited film was amorphous; however, an amorphous-to-crystalline phase transition was observed by ...

Effect of Magnetic Field on the Thermal Conductivity of Single Crystal

ABSTRACT This research investigated the effect of magnetic field on the thermal conductivity of high temperature type II superconductors. The result suggested that the thermal conductivity of high temperature type II superconductor YBa2Cu3O7- decreases as the applied magnetic field increases at a given temperature. We also found out that the superconducting energy gap of YBa2Cu3O7- decreases in response to increasing temperature and applied magnetic field. At a critical temperature of ...

Geophysical Investigation of Abakaliki Area using Aeromagnetic Method

ABSTRACT  Aeromagnetic data over Abakaliki area of the lower Benue trough of Nigeria was interpreted qualitatively and quantitatively using Oasis montaj software (version: 6.4.2 H.J).The interpretation unveiled basic intrusive bodies like dyke, lacolyte and batholyte in the study area. It also showed fault zone which trends North East to south western (NE-SW) part of the study area. Quantitative interpretation of the area was carried out by source parameter imaging and forward and inverse mo...

Investigation of Magnetic Anomalies of Ubiaja and Illushi Areas in Northern Anambra Basin Using Aeromagnetic Data

ABSTRACT The aeromagnetic data of Ubiaja and illushi area that fall within latitude to and longitude to were interpreted qualitatively and quantitatively. The qualitative interpretation revealed that the area is intensely faulted with major anomalies (faults) trending in the northeast and southwest directions. Standard Euler deconvolution, source parameter imaging (SPI), spectral analysis and modelling (forward and inverse) methods were employed in the quantitative interpretation aimed at det...

EXOSMOSIS AND ENDOSMOSIS VERIFIICATION USING WHITE RAW EGGS

ABSTRACT Exosmosis and endosmosis verification using white raw eggs have been carried out. Two beakers of dilute hydrochloric (HCl) acid solution were prepared. Two white eggs were placed differently into beakers labelled Beaker A and B respectively containing dilute hydrochloric (HCl) solution and left for five hours. Beaker A (containing Saltwater) was seen as more concentrated than the albumin in the egg. Water molecules moved from a low concentration point (albumin) to the high concentrat...

Structural and Optical Properties of ZnO Nano-Powder Synthesized by Combustion and Sol-gel Method

Abstract Nowadays, ZnO is considered as the most important chemical compounds due their distinctive properties owing to its wide band gab and large exciton binding energy. It is well known that the structural and the optical properties of ZnO differ by different methods of preparation. Therefore, in this work, ZnO power was prepared by two methods, namely sol-gel and combustion method with the aim of comparison. The obtained samples from both methods were investigated by many techniques for c...

Effect of Variations in Meteorological Parameters on the Tropospheric Radio Refractivity Over Lapai, Niger State, Nigeria

ABSTRACT The aim of this work is to examine the variations in meteorological parameters (Temperature, Atmospheric pressure, and Relative humidity)on the surface radio refractivity, N, in Lapai town, Niger state of Nigeria, with focus on the wet and dry seasons. Lapai town, being the study area, is located within latitude 9º 02ʺ N and longitude 6º 34ʺ E along Suleja road, about 56 km east of Minna, Niger state capital. Meteorological data obtained from the Nigerian Meteorological Agency (N...

Implications Of Radio Pulsar Crust Size On Its Braking Index

Abstract There are several obvious observable evolutionary evidence among all the population of known pulsars, but a consistent description of this evolutionary trend is generally lacking in the literature. In this study, we provide a consistent interpretation of this evolutionary effect, on the ground that the exchange of moment of inertia with time between superiud component and the solid crust component as the temperature of the neutron star drops is a signicant process of energy loss in ...

Long – Term Rotational Stability Of Some Isolated Radio Pulsars

ABSTRACT We re-examined the phenomenon of rotational instability in radio pulsars on decadal timescales using a sample of 315 radio pulsars whose spin-rates [rotation period (P) and spin-down rate ( P) ] have been measured on, at least two different epochs. The first stage of our analysis involves a direct comparison of the measured values of P and P at two epochs that are ~ 10 - 20 years apart in order to estimate the fluctuation in the parameters. The results show that the fluctuation in t...

Synthesis And Characterization Of Some Core-Shell Oxide Materials

ABSTRACT Core-shell oxide thin films of TiO2/MnO, TiO2/CoO, TiO2/NiO and TiO2/CuO have been successfully synthesized and deposited on glass substrates, using the chemical bath deposition [CDB] technique. To ensure uniform coating, surface pre-treatment was carried out by cleaning slides with detergent, deionised water, ammonia acid and rinsed with acetones. The core of the films was synthesized from TiCl3, NaOH and PVA while the shells were synthesized from MnCl2.4H2O, CoCl2.6H2O, NiSO4 and ...

Synthesis of Graphene-Polyaniline Nanostructured Composite For High Performance Super capacitators

Abstract Presently, there are deep concerns over the environmental consequences and the consumption of non-renewable energy sources, with the accelerated greenhouse effect which triggered enormous interest in the use of renewable energy sources e.g. solar, hydropower, wind and geothermal. However, the intermittent nature of harvesting renewable energy sources has recently gained considerable attention in the alternative, reliable, cost effective and environmentally friendly energy storage de...
