Injection wells in Ohio handled more wastewater from oil and gas drilling in 2012, especially from out-of-state sources in the Marcellus and Utica shales, but they are on pace to handle less of the material in 2013.

The continued uptrend in North America’s unconventional natural gas and oil supplies and global demand dynamics suggest that the outlook for pipeline and storage infrastructure development may not only be bullish but also long-term, according to analysts with Raymond James & Associates Inc.

Energy infrastructure giant Williams, whose pipeline partnership holds a bundle of huge natural gas and liquids operations in the Northeast, expects to see “full ethane rejection” through 2015, which will lead to “near-term headwinds” for the unit, CEO Alan Armstrong said Wednesday.

The United States has 2,384 Tcf of technically recoverable natural gas, the Potential Gas Committee (PGC) and the American Gas Association (AGA) said Tuesday. That’s more reserves than the PGC has calculated in its 48-year history and beats the previous high seen in 2010 by 486 Tcf.

A poll shows a majority of Ohio voters support new severance taxes on hydraulic fracturing (fracking) and natural gas liquids (NGL), especially if the revenue raised is used to cut state income taxes, an idea proposed by Gov. John Kasich.

Higher natural gas and oil resource estimates should continue through 2013 for several onshore unconventional areas, especially in “pockets of the Permian Basin,” the Niobrara formation, as well as the Eagle Ford and “super-rich” Marcellus and Utica shales, according to Credit Suisse.

The U.S. northern tier will be colder than normal over the next two months, with the northern Rockies and northern Plains in line for especially cold conditions, and Arctic air is expected to be a “frequent guest in [the] largest gas-demand population centers,” according to forecasters at Andover, MA-based Weather Services International (WSI). Above-normal temperatures are expected across the southern United States over the next three months, the forecasters said.

Marathon Oil Corp.’s third quarter profits jumped 11% year/year on strong revenue growth and increased production, especially from the Eagle Ford Shale.
