Private-equity-backed oil and gas producer Neptune Energy on Oct. 22 named former Louis Dreyfus executive Armand Lumens as its CFO.

Lumens worked with Louis Dreyfus Co. as its group CFO for less than two years and last month left the commodities trader citing personal reasons.

Lumens will join Neptune on Dec. 1, the company said in a statement.

Neptune, based in London, is backed by The Carlyle Group LP (NASDAQ: CG), CVC Capital Partners and China Investment Corp. The company is headed by former Centrica boss Sam Laidlaw.
