Here’s this week’s most important shale gas stories :

( 1 ) Company Cancels PA Pipeline Plans

AES Corp. has cancelled it’s plans to build a pipeline to deliver natural gas to Pennsylvania from Baltimore, Maryland, according to the Lancaster Online.

Read it:

“The 88-mile Mid-Atlantic Express pipeline would have carried natural gas from a terminal in Sparrows Point in Baltimore to Eagle in Chester County. Plans were to bring in liquefied natural gas from overseas and distribute it to domestic markets.”

AES Corp. filed the motion to cancel construction of the 88-mile pipeline on September 26.

( 2 ) Tanker Truck Fire at Carroll County Oil and Gas Well

There’s several questions to be answered regarding what caused a tanker truck to burst into flames at a gas and oil well near Carrollton, Ohio, Friday evening.

According to several reports, from The Morning Journal and the Times-Reporter, the fire began around 8:11 p.m. Friday night, off state Route 9.

Several fire crews responded, but around 9:30 p.m. the crews pulled back for safety reasons.

The well is operated by Rex Energy.

The company released this statement Saturday morning:

“In addition to the tanker truck, two holding tanks for condensate located on the site were involved, but the well itself was not affected,” Smith said. “There were no injuries and the well was quickly and effectively shut-in.”

An investigation into the fire is ongoing.

( 3 ) Shale Gas Drillers Must Report Chemicals

Natural gas and oil drillers will have to give up their chemical secrets, according to the Columbus Dispatch.

Ohio officials sent a memo to shale gas companies notifying them that a federal right-to-know law trumps a 2001 Ohio law.

The Ohio law allowed companies to send chemical information exclusively to the Ohio Department of Natural Resources.

Though it may be a victory for environmentalists, the law doesn’t require disclosure of every chemical ingredient, allowing companies to declare some ingredients as “trade secrets.”
