Apache has confirmed the retirement of its chief executive.
Steven Farris said he would step down from his role but continue as non-executive chairman of the board until May 1, 2015.
Mr Farris joined the firm in 1988 and has served as its chief executive officer since 2002 and as chairman of the board since 2009.
The 66-year-old was president and chief operating officer from 1994 to 2009, before taking the title of president in 2014.
Mr Farris said: “After more than 25 years with the company and 14 years as CEO, it is time to hand over the reins to a new generation of leaders.
“I look forward to working with John, the board and the management team over the next few months to ensure a smooth transition.”
Lead director Charles Pitman said: “I want to thank Steve for his leadership, dedication and decades of service to Apache.”
The firm’s executive vice president and chief operating officer John Christmann will replace Mr. Farris as president and chief executive officer and director John Lowe will be appointed non-executive chairman.
