Numerical Modeling of Wellbore Instability (TENSILE Failure) Using Fracture Mechanics Approach
(2013-05-12)
When a well is drilled, the equilibrium in-situ stress is changed. In order to support the stress relief induced by the drilling and to prevent hydrocarbon influx into the cavity, the borehole is filled with a fluid. These ...
Effect of Pressure on the Performance of Organic Light Emitting Devices Fabricated by Cold Welding
(2013-04-15)
Analytical and finite element models were used to simulate additive cold welding patterning processes. The effects of adhesion, pressure, thin film (layer) thickness and dust particle modulus (between the contacting surfaces) ...
The Effect of Bitumen Coatings on the Corrosion of Low Carbon Steels (API 5l X65)
(2013-05-12)
The corrosion behavior of uncoated and cut-back bitumen coated X65 Steel samples are being investigated in environments of different pH (2, 3, 4 and 7). Immersion tests were carried out on the samples at 25oC. The comparison ...
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 ...

(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 ...
Annealing Heat Treatment of Organic Material for Controlled Bulk Heterojunction Solar Cells
(2013-05-15)
The morphology of active layers of organic solar cells plays crucial roles in achieving good performing devices with longer life span. The process of fabricating these devices involved post deposition thermal annealing, ...
Face Verification with Statistical Models of Shape and Appearance
(2013-04-15)
Research in computer vision and machine learning is a significant part of research in computer science departments of many leading institutions resulting in ideas and products that have direct applications in different ...
Paclitaxel Loaded Polylactide-Co-Glycolide Acids for Coronary Artery Disease and Cancer Treatment
(2013-04-07)
The number one killer disease in the world is Cardiovascular Disease1. The most serious element of Cardiovascular Disease is Coronary Artery Disease. Currently, the main treatment for Coronary Artery Disease is stent ...
Directional Drilling Hydraulics Optimization using Conventional and Nanobased Drilling Fluids
(2013-05-25)
During drilling operations, special attention must be given to wellbore hydraulics to ensure functional, safe, economic, and environmentally responsible delivery of the well. The Hydraulics system shares common purposes ...
Quantifying Incremental Oil Production and Economics of using Intelligent Completion as a Tool for Reservoir Management
(2013-05-25)
Huge amount of hydrocarbon in place is left unrecovered. Integrated reservoir management, in addition to the use of new technologies improves hydrocarbon recovery. Intelligent completion is one of the technologies which ...
