Gas hydrate is one of the major plagues of gas wells in the industry, capital costs to prevent hydrate blockage in pipelines is an dissociation temperatures for the operating pressures. The model developed was tested on ...

Nigeria is blessed with mineral resources but unfortunately many have been poorly exploited. This has resulted to spending huge sums of money to import these minerals rather than taking advantage of available local natural ...

The main challenge of heavy oil (bitumen) is the high viscosity making it not flow easily to production wells at normal reservoir conditions. Thermal recovery methods are used to exploit heavy oil reservoirs, where oil ...

In this project, the optimum position of ESP is evaluated for horizontal wells. The inflow and outflow performance of the horizontal well has been estimated using Joshi’s steady-state approximation for horizontal flow and ...

Wellbore instability (WI) is one of the major challenges experienced during drilling operations costing the oil and gas industry over $1 billion yearly. During the drilling, borehole breakout and drilling induced fractures ...

Unconventional resources are of major importance to the oil and gas industry due to its enormousness, however, due to the low permeability of these resources, there is a need for hydraulic fracturing. Hydraulic fracturing ...

More than three decades have passed since Stewart Myers coined the term “real options” and introduced this new paradigm into the investment science. In the following years a number of publications in both the finance and ...

This study aimed at characterizing and evaluating the viability of barite deposits within Ribi for industrial applications. There is an inadequacy of information as regards mineralization, chemical and geotechnical properties ...

The organic-inorganic halide perovskite solar cells have continued to attract serious research interest since the first introduction as solar light absorber by Miyasaka and co-workers with a power conversion efficiency ...

Nigeria ranks among the top ten petroleum producers in the world with over eighty petroleum Investors in its upstream sector. This creates an enormous challenge for the upstream institutions’ managers especially in the ...

Globally, 30–50% of hydrocarbon volumes in silici-clastic reservoirs are contained within the thin-bedded pay. In the Niger Delta deep water assets, over 30% of in-place volumes are found within the complex turbidites. The ...

Wax is often precipitated out of solution in waxy crude oil found in most oil reservoirs around the world, especially as the production of oil and gas has moved from on shore to more challenging terrains offshore. Waxes ...

Although there have been significant efforts in breast cancer treatment over the past many decades, current therapeutic approaches are limited by non-specific systemic distribution, inadequate drug concentrations ...

Due to the growing concern of deforestation, renewable materials such as recycled cellulosic waste and non-wood fibres provide an alternative solution for partial replacement of wood resources as a reinforcement agent in ...

The aim of this dissertation is to contribute to efforts towards increasing the use of Nigerian barites in drilling mud production and other industrial applications. In order to achieve the above objectives, three projects ...

This work presents the results of a combined analytical and experimental study of the effect of reinforcement on the corrosion and adhesion ability of epoxy coatings. Firstly the corrosion behavior of 5-hydroxytryptophan ...

Perovskite solar cell (PSC) has emerged as a promising photovoltaic technology due to their prospects for high efficiency and low cost. Despite the impressive improvement in their power conversion efficiency (PCE) over the ...

This thesis explores the cytoskeletal structures and the statistical variations in the cell-protein fluorescence intensities/volume densities, creep characteristics, and viscoelastic properties of non-tumorigenic breast ...

Data analytics has only recently picked the interest of the oil and gas industry as it has made data visualization much simpler, faster, and cost-effective. This is driven by the promising innovative techniques in developing ...

This study characterizes barite ores and uses environment-friendly and indigenous processes to develop technologies, methods and mineral processing tools for barite recovery from gangue minerals. The study is in four parts. ...
