A new era of natural gas exploration is spreading across the continental United States and Canada. Through a technique called hydraulic fracturing (fracking), huge deposits of oil shale, like the Marcellus and Utica deposits that extend from the Appalachians and into Canada, are now producing enough gas to meet North America’s needs for the next 14 years. The boom in gas exploration has opened up new markets for pipeline and joint coating materials to provide corrosion protection. Estimates of pipeline construction in Pennsylvania alone are in the range of 12,000 to 27,000 miles by 2030.
