The scope of this work was to make detailed analysis of phase distribution in a horizontal pipe. This detailed analysis has been successfully carried out. Data obtained from wire mesh sensor (WMS) were used for the analyses. ...

During polymer flooding in the reservoir using shear-thinning non-Newtonian fluids, an interface exists between the in-situ Newtonian crude in the reservoir and the injected polymer solution. This work examines application ...

The morphology of active layers of organic solar cells plays crucial roles in achieving good performing devices with longer life span. The process of fabricating these devices involved post deposition thermal annealing, ...

With more than millions of pages, the Web has become a greatly enormous information source. This information is in form of documents, images, videos as well as text. With such vast sizes of data, it is a common problem to ...

A major drawback of directional and horizontal well drilling is the numerous complex computations required to be done while planning a well. These computations are very stressful and time consuming especially when done ...

In this study, we present a new analytical solution method that accurately corrects the non-isothermal effects from injection and fall-off tests. The derivative of these solutions is applied to develop the Tiab's Direct ...

The rate of CO2 emissions from manufacturing industries and some manufactured products in service or at the end-of-life use is really troubling and needs attention. The CO2 contribution from the automotive or transportation ...

Developing countries have been plagued by recurrent cases of infectious disease outbreaks;coupled with the limitation of traditional disease control strategies, other approaches have been explored for disease control, with ...

Cyber threats are currently on the rise, which has caused individuals, industrial control systems (ICSs), critical infrastructures (CIs), and nations to be subjected to attacks with great losses. Among the cyber threats ...

In the world today, the size of complex problems and systems has increased, due to the advances in technology and the area of computer design and architecture. Modeling and predicting the behaviour of complex systems ...

This research describes the application of a production economic approach which attempts to quantity stimulation treatments performed on different wells undergoing a decline phase in their production and to obtain based ...

Well stimulation consists of several methods used for enhancing the natural producing ability of the reservoir when production rate declines. A de tailed literature review of some of the well published stimulation models ...

Waterflooding is the most dominant secondary oil recovery method and its popularity is mainly due to the general availability of water, the relative ease of injecting water, the ability of water to spread easily through ...

Reservoir development planning and well placement significantly affect hydrocarbon recovery. Therefore, strategic well placement and development techniques are essential to minimize the risk of unproductive drilling and ...

In this thesis, we consider the problem of approximating solution of generalized equilibrium problems and common fixed point of finite family of strict pseudocontractions. The result obtained is applied in approximation ...

In this thesis, an iterative algorithm for approximating the solutions of avariational inequality problem for a strongly accretive, L-Lipschitz map and solutions of a multiple sets split feasibility problem is studied in ...

Let H1 and H2 be two Hilbert spaces and Aj : H1 → H2 be bounded linear operators and Ui: H1 → 2H1, Tj : H2 → 2H2, 1 ≤ i ≤ n, 1 ≤ j ≤ r be two multi-valued demi-contractive operators with demi-contractive constants βi and ...

From the inception of the oil and gas industry, water production has always been an aching problem for various operators. Throughout the productive life of a field, oil production is often accompanied with some amount of ...

Nigeria economy solidly depends on fossil fuels, which serve as the major source of energy and revenue. Fossil fuels, especially petroleum, are readily available to meet the increasing energy demand of a growing population. ...

Drilling fluids play sophisticated roles in the drilling process which include, keeping formation fluids at bay, stabilizing the wellbore without damaging the formation, lubricating the bit and drill-string and clearing ...
