Petrophysical Evaluation and Depositional Environments of Reservoir Sands of X Field, Offshore Niger Delta, Nigeria

ABSTRACT This study involves the use of geophysical well logs to characterize four reservoir sand bodies contained in four wells offshore Western Niger Delta. The well logs include caliper, SP, gamma ray, resistivity, neutron (NPHI), density (RHOB) and sonic logs. The logs were obtained in digital data format and a Paradigm's petrophysical software, Geology was used to process the data into logim ages. This aided the visual identification of lithologies and potential reservoirs. The reservoir...

Modification of Darcy's Law for Turbulent Flow in Saturated Porous Media

Abstract Darcy's law is an essential equation in determining the permeability of porous media, which is vital tool in seepage and drainage control in soils. However, whenever the aggregate sizes of the porous media and hydraulic gradient are large, the flow in drains will be semi-turbulent to turbulent. This research aims at modifying the true Darcy's permeability determined under small hydraulic gradients that ensure laminar or nearly laminar flow to allow for reduced efficiency caused by t...

Pattern of Sexually Transmitted Diseases Among HIV-1 Infected Commercial Sex Workers in Ibadan, Nigeria

ABSTBACT This study evaluated the association of HXV-1 infection with some other sexually transmitted diseases (STDs) among femaIe commercial sex workers. BIood samples were collected from 250 female commercial sex workers in Ibadan Oyo State, Nigeria and tested for the presence of HEV antibodies using ELJSA and Western blot. Endocervical and high vaginal swab samples were also collected for microscopy and culture. The prevaIence of HIV-1 infection among CSWs in Ibadan, Nigeria was 25.6% wit...

The Concentration of Heavy Metals in Selected Clay Samples in Ekiti State, Southwestern Nigeria

ABSTRACT The presence and possible effect of heavy metal (such as cadmium, zinc, lead, e.t.c) concentration in the clay used in pot making were investigated. Clay samples were collected at three locations where they are used mostly in making pots and other kitchen utensils. The concentrations of heavy metals were determined using the Atomic Absorption Spectrometer (AAS). Results indicate that the concentration Cu, Zn, Cr, Pb, As, and Mn falls within the range of the maximum admissible concen...

Hermetic Control Treatment of P. truncatus (Horn) (Coleptera: Bostrichidae) Infestation on Stored Dried Cassava Chips in Poly then Bags

Abstract The focus of this research work was on the hermetic control treatment against Prostephanus truncatus Horn, 1878 infestation on dried cassava chips, over an infestation period of 10 weeks in the store. The experimental set-up was done in three hermetic treatments, this include, single bag, double bags and triple bags treatment. Each treatment was replicated 15 times. The used bags were made up of polythene material, with 0.056 mm thickness and 360 mm x 600 mm in dimension. The bags w...

ABSTRACT A 1O-week cross-sectional study was carried out at the Adeoyo State Maternity Hospital(Beere, Ibadan), Southwestern Nigeria in order to determine (a) the prevalence of severe malaria, (b) identify the predominant clinical presentations that characterise the disease in children below 5 years and the pattern of antibody responses to MSP 119elicited in severe malaria complications. Three thousand, one hundred and thirty-one cases reported to the Out Patients' Department; of these, 372 (...

Investigation of Groundwater Development in four Areas of Ido Local Government South-Western, Nigeria Using Electrical Resistivity Method

Abstract This study focuses on the use of geo-electrical sounding for groundwater prospecting in four areas namely Ido Motor Park, (N 07' 18' 40.3", E 003' 50' 29.2") Elere- Apata '(N 07' 18' 40.3", E 003' 50' 29.2") Bakatari (N 07' 18'40.3", E 003'50'29.2'') and Apete Market (N 07' 18' 40.3", E 003'50' 29.2") in Ido local government area Southwestern Nigeria. Two (2) Vertical .electrical soundings (VES) were carried out using Schlumberger configuration at each of the selected area making a ...

Trends and Policy Correlates of Agricultural Production and Agricultural Production Sustainability Outcomes in Ghana and Nigeria

ABSTRACT This paper analysed policy correlates of agricultural production and agricultural production sustainability outcomes in Ghana and Nigeria. It underscores the influence of political systems and international development agendas as correlates of agricultural production and agricultural production sustainability outcomes. This is to the extent of providing evidence policy on agricultural production and agricultural production sustainability outcomes. Ghana and Nigeria have comparable fa...

Candidaemia or Candidasis: Controversy of Staphylococcus Sexually Transmitted Infections

ABSTRACT Herbal medications are becoming increasingly popular but a most-extraordinary claim by traditional/herbal medical practitioners relates to a Gram-positive bacterium, Staphylococcus, which has been depicted as a deadly sexually transmitted disease that manifest in the form of worms and other symptoms; with contributory roles including infertility, sexual dysfunction and impotency. They further boasted that they are the only ones that possessed the remedy (herbal) for the Staphylococcu...

Sequence stratigraphic framework of K-field in part of Western Niger delta, Nigeria Sekvenčna stratigrafija naftnega polja K v zahodnem delu delte reke Niger, Nigerija

ABSTRACT A sequence stratigraphic approach was applied to K-Field, within the western Niger Delta by integrating wireline logs of four wells; 001,003, 004 and 005; and high resolution biostratigraphic data of wells 001, 004 and well 005. The study is aimed at deducing key bounding surfaces, depositional sequences and their corresponding systems tracts as well as the palaeodepositional environment of the hydrocarbon bearing Agbada Formation in the study area. Two sequence boundaries at 8900 ft...

Sedimentological Characteristics and Aspects of Hydrocarbon Potential of Kinasar-1 Well Sediments, Bornu Basin, Northeastern Nigeria

ABSTRACT Subsurface samples from Kinasar-1 well, in the Bornu basin, northeastern Nigeria, were studied to deduce the lithofacies distribution, provenance, palaeodepositional environment and paleotectonic conditions of the basin. In addition, the hydrocarbon potential of the associated shales has been highlighted. The lithological sequence comprised a basal unit of over 1300m coarse grained sandstone of the Bima Formation, overlain by 1200m shaly unit with a sandy base, belonging to the Gongi...

Rationale For Vitamin C Treatment For Covid 19 and Other Viruses

Vitamin C and Coronavirus: Not a Vaccine; Just a Humble Cure Commentary by William F. Simmons and Robert G. Smith, PhD During the pneumonia epidemic in North Carolina in the 1940's, after American soldiers returned from the war in Europe, a small-town physician used an anti-infective protocol of intravenous vitamin C to cure 42 cases of viral pneumonia. [1] During the same period, the physician used a similar treatment to cure 60 cases of viral poliomyelitis. All patients were clinicall...

Monitoring the Effect of Water pollution In Twelve Selected Water Dams in Osun State of South Western Nigeria

ABSTRACT The level of water pollution by heavy metals ' (Cu, Xn, Co, Ni, As, Mn, Cd, Cr. !)hi in twelve selected water Dams in Osun state were determined in order to know their distribution and possible source into the dams. Their bottom sediment and water  were colIected for analysis. The result in sediment showed that .the concentration of Manganese is high in all the dams with values ranging from 21,27-775.39mgkg and it spreads across all the locations. Cobalt was detected only at one. lo...

Variations in species composition and infection rates in Anopheles gambiae s.l. across eco-vegetational zones in Nigeria and Cameroon

ABSTRACT Significant variations in vector biology within and between countries have been reported in malaria epidemiological studies1. It is now generally agreed that a clear understanding of the detailed epidemiology of the disease is a pre-requisite to effective malaria control in the African sub-region2. Anopheles gambiae complex (Diptera: Culicidae) is one of the most efficient vectors of Plasmodium falciparum in the African sub-region; it is a complex of sibling taxa3. Two of these sibli...
