An Integrated Approach to Selecting and Optimizing Demulsifier Chemical Injection Points using Shearing Energy Analysis: A Justification for Downhole Injection in High Pressured Well
(Offshore Technology Conference, 2011-05-05)
Chemical demulsifiers are routinely injected into the petroleum production system at several points to effectively resolve water-in-oil emulsion issues. Point of injection varies from downhole through wellhead and manifolds ...
Implantable Biomems Devices for Localized Breast Cancer Drug Delivery
(2011-12-15)
Implantable Bio-Micro-Electro-Mechanical Systems (BioMEMS) represent a new class of devices that can provide localized cancer drug delivery by the combined effect of chemotherapy and hyperthermia which gives it an advantage ...
Modeling of Cold Welding and Lamination of Organic and Hybrid Organic /INORGANIC Structures
(2011-12-15)
This research work presents the results of analytical studies of effects of pressure and adhesion energy on the interfacial properties of cold welded and laminated surfaces in organic and Hybrid Organic/Inorganic electronic ...
Abrasive Wear Studies of Pack Cyanided Mild Steel (PCMS)
(2011-12-15)
This work aimed at using processed cassava leaves to pack cyanide mild steel (MS) under different treatment conditions and investigating the wear properties of the pack cyanided mild steel (PCMS). Pack cyaniding (PC) of a ...
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 ...
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 ...
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 ...
Biosynthesis of Magnetic Nanoparticles for Cancer Detection and Treatment
(2011-12-15)
Chemical and physical methods for the synthesis of magnetic nanoparticles for cancer detection and treatment often involve toxic chemicals, high cost and the formation of non-stable nanoparticles. This prompted the development ...
