A six-foot section of a 20-inch diameter Columbia Gas Transmission system that ruptured Dec. 11 in West Virginia had wall thickness measured as low as 0.078 inches, significantly thinner than the nominal wall thickness of 0.281 inches when the pipeline was installed in 1967, according to a preliminary report issued Wednesday by the National Transportation Safety Board (NTSB).

In the midst of continued oil/natural gas production growth, albeit at a slower pace, North Dakota’s drilling activity has slowed significantly and the amount of hydraulic fracturing (fracking) even more so, according to the state’s top oil/gas official. Activity is projected to increase again next year, however, with continuing technology advances.

The wall thickness of a section of pipe on the 20-inch diameter Columbia Gas Transmission system that ruptured Tuesday in West Virginia was significantly deteriorated, said National Transportation Safety Board (NTSB) investigators Thursday. There also was a pressure drop on the line, but the magnitude of the decrease is unknown as was whether drop was the result of the rupture or its cause.

Williams is taking the long view on North America’s natural gas, agreeing last week to significantly build its onshore pipeline network by putting up to $2.4 billion into a system once owned by Chesapeake Energy Corp.

Greenhouse gas (GHG) emissions from shale gas well hydraulic fracturing (fracking) operations are significantly lower than previously estimated, according to a study by researchers at the Massachusetts Institute of Technology.
