Chesapeake Says It Has Received Subpoena From Antitrust Office

Chesapeake Energy Corp. (CHK), the second- largest U.S. natural-gas producer, received a subpoena in June from the antitrust division of the U.S. Justice Department’s Midwest Field Office.

The subpoena comes amid an investigation into possible violations of antitrust laws related to the purchase of oil and gas rights, the Oklahoma City-based company said in a regulatory filing today. The request calls for Chesapeake to provide certain documents to a grand jury in the Western District of Michigan, the company said.

Chesapeake also has gotten demands for documents and information from some state government agencies related to other investigations of buying and leasing oil and gas rights, according to the filing.

Exxon Mobil Corp. (XOM) is the largest U.S. gas producer.
