Oil and gas transmission pipelines are critical items of infrastructure in providing energy sources to regions and countries. Steel pipes are commonly used which can be subject to both internal and external corrosion. This paper presents an advanced nondestructive inspection technique for detection of oil-gas pipeline corrosion defect. The Pulsed Eddy Current (PEC) method has been successfully ...

This research uses multivariate cointegration analysis to assess the degree . of competition in the U.S. natural gas industry following the move to open access pipeline transportation. The testing methodology allows multiple nodes in the pipeline network to be analyzed simultaneously and is based on recent advances by Johansen (1988, 1991) and Johansen and Juselius (1990) on estimation and hypo...

On January 27, 2016, the Government of Canada announced that “direct and upstream greenhouse gas emissions” would factor into the regulatory review process for proposed pipeline projects.1 The new standard aims to address claims that new pipelines will induce greater expansion of Canada’s oil sands, producing more greenhouse gas (GHG) emissions. Specific details were not provided in the governm...
