"While Chesapeake is a strong and resilient organization that reflects our incredibly talented employees, we must adapt our organizational structure to become a sustainable, profitable company in the energy sector. Future staffing adjustments will likely be necessary to properly align resources and improve our overall operating and competitive performance," said Chesapeake's CEO Doug Lawler in the email, a copy of which was obtained by CNBC.

A comprehensive review of all areas of the company's business is underway and is being led by managers and employees from all levels, he said.

CNBC reached out to Chesapeake for comment, but has not yet received a response.
