New chairman as Oil Search turns on the gas A NEW chairman is the first sign of big changes to come at Papua New Guinea's Oil Search, where longstanding managing director Peter Botten and his board are considering internal structural change to ensure shareholders get more payouts when the $US19.5 billion ($19bn) PNG LNG project starts next year. Oil Search on Monday announced that recently installed board member Rick Lee, a former head of Rothschild Australia and CSR executive, would become chairman, replacing Brian Horwood at the end of this month.
