Drilling techniques questioned at lecture (23-Feb)
"One of the country’s leading environmental journalists echoed concerns about underground drilling techniques used by several of Oklahoma’s largest employers at a lecture series in Oklahoma City last week.
Anne Thompson, Chief Environmental Affairs Correspondent for NBC News, said that there were still many unanswered questions about hydraulic fracturing, a process used by Chesapeake Energy, Devon Energy and Sandridge Energy to distract natural gas from beneath the earth’s surface. The process, which has been in practice since the 1940s, is the focus of an Environmental Protection Agency study requested by the U.S. House of Representatives. "It could be the bridge to get us off oil,” Thompson said. “The question is, in getting it, are we doing more harm than good?”
