Chesapeake Energy Corp. (NYSE: CHK) is considering selling some of its assets in Oklahoma's Stack shale field, Bloomberg reported.

The company has held talks with advisers and potential buyers, Bloomberg reported on March 9, citing people familiar with the matter.

Chesapeake was not immediately available for comment.

The company said last month that it planned to sell assets worth $500 million to $1 billion this year to reduce debt.

Asked if Stack shale assets were among those marked for sale, Chief Executive Doug Lawler had then said on a post-earnings call that the company did not have any current plans, but he had not ruled it out.

The Stack shale assets Chesapeake is considering selling could fetch $300 million to $700 million, Bloomberg reported, citing one of the people.

Chesapeake's shares were up about 7% at $4.61 in afternoon trading on March 9, mirroring a broad rally in oil and gas stocks due to higher crude prices.
