Temperature Prediction Model for Flowing Distribution in Wellbores and Pipelines
(2011-12-12)
Down-hole temperature and pressure data are important information needed to understand flowing conditions and production optimization. For example, knowing the wellbore temperature profile is useful in predicting the wax ...
A-Three Dimensional Numerical Simulator for Expansion-Drive Reservoirs
(2013-05-25)
Every simulation study is a unique process, starting from the geological model and reservoir description to the final analysis of recovery factor optimizations. In petroleum engineering area, numerical reservoir simulators ...
Evaluation of Petrophysical Properties in the Ak Field of the Niger Delta Province of Nigeria Using Integrated Data
(2013-05-25)
The AK field is an oil field draining the Agbada Formation, one of the three units of the Niger Delta Province, which started forming about 50 million years ago. Reservoirs from the AK field are sandstones and are located ...
Prediction of Surge and Swab Pressure Profile for Flow of Yield Power Law Drilling Fluid Model through Eccentric Annuli
(2011-12-12)
Surge and swab pressure computation is very important in drilling hydraulics. Most blowout problem in oil wells have been as a result of surge and swab pressures developed from running or pulling of tubular goods in ...
Investigating the Impact of Pressure Depletion on the Estimation of Reserves and Recovery Factors in Naturally Fractured Reservoirs
(2014-12-20)
The complexity of naturally fractured reservoirs poses constrains on reservoir engineers in estimating reserves and recovery factor in naturally fractured reservoirs. Naturally fractured reservoirs like all other hydrocarbon ...
Power-Law Fluid Pressure Behaviour in Homogenous and Naturally Fractured Reservoir with Spherical Flow
(2013-04-30)
Studies have revealed most wells are usually completed with limited or restricted-entry and it’s often characterized with spherical flow behaviour. High viscosity crude by their nature may also exhibit Non-Newtonian flow ...
Development of Coning Correlations for Oil Rim Reservoirs using Experimental Design and Response Surface Methodology
(2014-12-20)
Proper management of thin oil rim reservoirs is required to maximize recovery and minimizes coning tendencies. The objective of this study is to determine the effect of reservoir and fluid properties on coning tendencies ...
Implantable Biomedical Devices for Localized Breast Cancer Drug Delivery
(2015-10-15)
This thesis focused on an implantable encapsulated structures that can deliver localized heating and controlled released of prodigiosin (PG) (a cancer drug) synthesized by bacteria (Serratia marcescens (subsp. marcescens)). ...
Uncertainty Analysis in Simulation for Reservoir Management: Case Study from Niger Delta
(2016-04-13)
Uncertainty analysis of flow performance predictions involves identifying significant reservoir parameters impacting the flow response. Uncertainty analysis often requires conducting large number of reservoir simulation ...
Layered Composite thin Films for Cost Effective Transparent Organic Solar Cell Electrodes
(2015-08-20)
In this dissertation two main themes are explored. In the first part some phenomenologies of light transport across the ZnO/Al/ZnO (ZAZ) thin film multilayer structures are investigated. The multilayered ZAZ thin film ...
