In an article in an ongoing series on unconventional gas drilling in the New York Times, “Drilling Deep,” reporter Ian Urbina reports that the NYS Attorney General has subpeonaed five gas drilling companies:

The New York attorney general, Eric T. Schneiderman, sent subpoenas to five oil and gas companies ordering them to provide documents relating to the disclosure the companies made to investors about the risks of hydrofracking, according to sources briefed on the investigation.

A spokesman from Mr. Schneiderman’s office declined to provide copies of the subpoenas.

The five companies subpoenaed — Talisman, Chesapeake Energy, E. O. G. Resources, Baker Hughes and Anadarko — all declined to comment.

There is no press release on this from the Attorney General’s office on his website.
