Failure Mechanisms of Epoxy Coatings in Pipelines
(2013-05-12)
Epoxy, a thermosetting polymer due to its attractive properties, has been widely used in many industries as a coating material such as the oil and gas industries. This study provides an insight into the corrosion behavior ...
Modeling and Simulation of Stress Distribution and Crack Configuration of the Geometry of Ceramic Water Filter
(2011-12-15)
Most countries in Africa are faced with difficult challenges in terms of providing safe, clean drinking water for their citizens. The world Health organization estimates that approximately 500 lives are lost per day in ...
Bioinspired Design
(2013-05-12)
Bioinspired design involves the use of concepts observed in natural biological materials in engineering design. The hope is that the leveraging of biological materials in the engineering domain can lead to many technological ...
An Experimental Model to Predict and Control Oilfield Emulsion Tightness: a Novel Approach
(2010-12-12)
Formation of water-in-oil emulsions are among the major challenges encountered by production and surface facilities engineers during the recovery of crude oil, especially in a large multi-wells system in both onshore and ...
Optimization of Strategies for Natural Gas Utilization: Case Study of the Niger Delta
(2010-12-12)
Nigeria is endowed with huge proven gas reserves estimated to be 184 trillion cubic feet (Tcf). It ranks as the 7th holder of natural gas reserves in the world, and the largest in Africa. Nigeria also flares more natural ...
Prevention of Hydrates in Pipelines using Hybrid Thermodynamic Inhibitors
(2010-12-12)
Chemical method is the most efficient and flexible method of hydrate control in offshore operations. In recent times, polymers and surfactants have been used to influence the kinetics of hydrate growth and coagulation. ...
Combined Effect of Rheological Model and Equivalent Diameter Definitions on Pressure Losses/Equivalent Circulating Density Estimation
(2011-12-12)
Without accurate estimation of annular pressure losses it is possible to face serious problems that would yield to interruption in drilling operation and
sometimes lead to the abandonment of the well. Therefore, exact ...
Development of a Computer Program for Solids Control
(2011-12-15)
Computer software is used extensively to increase productivity and reduce man's hours of labour. This work presents the development of a solids control software (SOLCON) which is designed for real time mud system management ...
Building and Ranking of Geostatistical Petroleum Reservoir Models
(2010-12-12)
Techniques in Geostatistics are increasingly being used to generate reservoir models and quantify uncertainty in reservoir properties. This is achieved through the construction of multiple realizations to capture the ...
Graphical Evaluation of Cuttings Transport in Deviated Wells using Bingham Plastic Fluid Model
(2011-11-23)
The transportation of cuttings and efficient hole cleaning are indispensible in any drilling program. This is because a successful drilling operation is the key to a profitable business in the oil and gas sector. A successful ...
