Ark-La-Tex region is at the intersection of Arkansas, Louisiana, Texas and Oklahoma.

QR Energy said it will finance the deal, which is expected to close in late April, with cash on hand and borrowings under its bank credit facility. The deal is expected to immediately add to distributable cash flow.

Last September, the company bought oil and natural gas properties located in the Permian Basin, Ark-La-Tex and the U.S. mid-continent for $577 million.

Shares of QR Energy closed at $22.36 on Friday on the New York Stock Exchange.
