Argentina's state-run YPF energy company says it will disclose clauses of an investment deal with U.S.-based Chevron Corp. to produce oil and gas by hydraulic fracturing in one of the world's largest shale deposits.

The decision announced by YPF on Wednesday seeks to end a three-year legal fight over the deal for the Vaca Muerta deposit in southern Argentina.

YPF says its lawyers will turn in a copy of the contract to a local court Thursday.

It follows a 2013 request by a local lawmaker who alleged that the deal had secret clauses after YPF refused to disclose environmental and other information on the project.

Argentina's Supreme Court and a federal appellate court ordered YPF to release all of the contract's provisions.
