KKR is close to avoiding a serious leak in its natural gas producer Samson Resources.

A JPMorgan-led group that holds a $1 billion revolving line of credit is nearing a deal that will give Samson a waiver for an expected covenant breach.

The announcement could come as soon as Wednesday, a source said.

The Federal Reserve has been pressuring JPM and other banks to increase their reserves against energy loans — making it uncertain a few weeks ago whether Samson would get a waiver.

Several other natural gas producers are facing similar issues with their lenders. For example, Quicksilver Resources filed for bankruptcy Tuesday.

Under the expected deal, the JPM-led group will reduce the size of the revolver.

“It will be lowered, but it is not drastically different,” a source with good knowledge of the discussions said.

In 2014, the same creditors reduced the revolver from $1.8 billion and waived a covenant breach.

KKR in 2011 led a $7.2 billion buyout of Samson, and even with the expected waiver is still in trouble.

Samson has an interest payment due in August to its more junior creditors, and may run out of money later this year, sources said.

JPMorgan, Samson and the Fed declined comment.
