The concurrent flow of gas/liquid in pipes poses a great challenge due to the difficulty associated with the flow of fluid. The flow is characterized by the existence of flow regimes which can be identified by the geometrical ...

The need to re-develop one of the Brown fields located in the Niger Delta area of Nigeria was necessitated by the fact that there are still three undeveloped reservoirs in the field. A total of six stacked reservoirs, A100 ...

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 ...

Magnetohydrodynamics (MHD) boundary layer flow problems have become important in industrial manufacturing processes such as plasma studies, chemical engineering, electrochemistry, polymer processing, petroleum industries, ...

The Java programming language is widely used in industry and business. Therefore, academic institutions worldwide include Java learning as a basic part of their Computer Science and Engineering curricula. At the same time, ...

Traffic simulation has become one of the most used approaches for traffic analysis in support of the design and evaluation of traffic systems. Although traffic flow models have been applied for almost a century to describe, ...

System control has grown from manual control where humans sense the environment, analyse the result and determine control actions to semi-automated control. In semi-automated control sensing is done by sensing devices and ...

The Opportunistic network is an interesting development in the Mobile Ad hoc Network (MANET) environment. It has no end-to-end connectivity among nodes. Unlike MANETs, the nodes in Opportunistic network are independent on ...

Many Institutions offer on-line courses to people from all around the world. Learning Management Systems provides a convenient learning environment for on-line courses. Each learner has individual needs and characteristics ...

Clastic reservoirs may be heterogeneous and exhibit lateral and vertical variations in porosity and permeability. Therefore, the spatial distribution of the petrophysical properties within the reservoirs is important to ...

The study area which is the Niger Delta Province is predominantly an unconsolidated sandstone terrain, the sand grains are friable suggesting the expectation of some geomechanical problems while developing hydrocarbon ...

The Internet of Things (IoT) has generated a large amount of research interest across a wide variety of technical areas. These include the physical devices themselves, communications among them, and relationships between ...

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 ...

This research work mainly investigates the implication of void prediction in the estimation of total pressure gradient in vertical pipes for multiphase flow systems. Experimental data was collected for a multiphase flow ...

Gas condensate reservoirs are single phase at the initial condition. It changes to multiphase when the reservoir conditions are located between the critical point and the cricondentherm of the reservoir in the phase envelope. ...

Advanced Persistent Threats (APTs), represent sophisticated and enduring network intrusion campaigns targeting sensitive information from targeted organizations and operating over a long period. These types of threats are ...

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 ...

Optimizing the placement of new wells and well spacing is a vital issue in oil field development. Drilling infill wells is one way to maximize the recovery of oil from reservoirs. The problem of infill well placement is ...

Density-Functional Theory (DFT) offers a simplification to electronic structure problems by using the electron density instead of the wave-function. Unlike the wave-function which is a function of 3N variables (excluding ...

Ground State structures of neutral Copper clusters Cu N =3−6 were generated and optimised within the framework of the Density Functional Theory (DFT) using Generalised Gradient Approximation (GGA) and ultrasoft pseudopotential. ...
