Mechanistic Models for Predicting Sand Production: a Case Study of Niger Delta Wells
(2014-12-12)
Niger Delta Province is predominantly a friable, unconsolidated sandstone terrain suggesting the expectation of sand production while developing hydrocarbon reserves in such terrain. In this study, a simple and easy-to-use ...
Ultrafast X-rays Imaging For Medical Physics
(2016-06-17)
In this thesis we explored the production of highly coherent and energetic extreme ultra violet(XUV) radiation through the process of high harmonic generation(HHG). HHG is a process by which a ultrashort laser pulse interact ...
Detailed Analysis of Pressure Drop in a Large Diameter Vertical Pipe
(2014-12-15)
With the ever increasing need to optimize production, the accurate understanding of the mechanics of multi-phase flow and its effect on the pressure drop along the oil-well flow string is becoming more pertinent. The ...
Material Balance Application for Brownfield Development
(2016-06-12)
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 ...
Spontaneous Flow Transitions in Active Polar Gels
(2011-11-20)
Active polar gels are a type of viscoelastic soft material formed by polar filaments which are constantly driven out of equilibrium by the consumption
of chemical fuel such as ATP. Following the approach of Voituriez et ...
Quantum Simulation of a Transverse-Field Ising Model
(2010-12-20)
A popular model that have been used to study ferromagnetism is the Ising Model which is an arrangement of spins along a particular direction and with discrete values of + 1 . 1-D Ising model doesn't show a phase transition ...
Existence and Uniqueness of Solutions of Integral Equations of Hammerstein Type
(2013-05-27)
Let X be a real Banach space, X ∗ its conjugate dual space. Let A be a monotone angle-bounded continuous linear mapping of X into X ∗ with constant of angle-boundedness c ≥ 0. Let N be a hemicontinuous (possibly non-linear) ...
Artificial Neural Network for Diagnosis & Mitigation of Water Production
(2016-06-12)
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 ...
Analysis of Void Fraction Phase Distribution of Gas-Liquid Flow In a Horizontal Pipe Using Wire Mesh Sensor Data
(2014-12-15)
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. ...
