Conventional oil production in Western Canada has experienced a resurgence in the past few years due largely to new drilling and completion methods, according to a report from the independent Canadian Energy Research Group (CERI).

The Keystone XL pipeline would cause “no material impact” on greenhouse gas (GHG) emissions in the U.S., according to a new IHS study.

Fracking in the Marcellus Shale has markedly increased the supply of natural gas produced in the Appalachian Basin, which is typically of higher quality than gas produced from the Gulf. This increased supply has resulted in a shift in the historical pattern of gas flow.

DNV’s latest revision to Offshore Standard for Submarine Pipeline Systems, DNV-OS-F101, will be the pilot for a new approach to rule development, competence management, communication and application.

Doug Evans, outgoing president of IPLOCA and CEO of Gulf Interstate Engineering, welcomed 651 delegates to Washington, DC for the 47th annual convention of the International Pipeline and Offshore Contractors Association. Contractors and suppliers to pipeline construction companies gathered in the nation’s capital for five days of technical presentations, meetings, social events and tours.

Conventional wisdom tells us that pipelines operating at a sufficiently low hoop stress are immune to failing in a rupture mode and can only fail in a leak mode.

In general, that’s true. However, a recent study found that some pipelines that are operating below 30% specified minimum yield stress (SMYS) have an increased chance of low-stress ruptures and subsequent failures under certain conditions – namely select low- and high-frequency electric resistance welded (ERW) pipes with seam weld corrosion.

Philip Luna is a man on the go, and if you work for him at Houston-based UniversalPegasus International (UPI), you’d better be as well, even if it means getting to work for the 7 a.m. team meeting.

Pipeline & Gas Journal’s 33rd Annual 500 Report offers the industry’s most comprehensive statistical review of U.S. energy pipeline systems. As in past years, the report ranks the nation’s top gas distribution, liquids and gas transmission systems. Transmission companies are ranked by mileage, while the rank of each liquids pipeline company is based on yearly crude deliveries. The gas distribution rankings are based on number of customers.

One of the best ways of gauging the strength of an industrial economy is watching the return of the steel industry. As the shale revolution continues to evolve in the U.S. and eventually Canada, owners of steel mills are restarting furnaces, expanding and building new facilities to fashion the new pipelines that will carry oil and natural gas to market.

There’s little debate that switching from fuel oil to natural gas, with its lower emissions, domestic abundance and low and stable price point, represents an opportunity for fuel-intensive businesses in North America. There’s also no argument that pipelines are the best method for delivering gas. But for businesses located off a pipeline route, the tumble in natural gas prices hasn’t benefited them nearly as much as it has their competition. For some, pipeline projects may come eventually; for others, there is no construction even being discussed.
