Petroleum Development Oman (PDO), the Sultanate's dominant oil and gas producer, aims to invest in excess of USD10 billion in a trio of signature integrated schemes that are key to sustaining the company's long-term hydrocarbon output. All three mega ventures -- the Rabab Harweel Integrated Project (RHIP), the Yibal Khuff integrated oil and gas facility, and the Budour integrated project --are making commendable headway in their planning and implementation, according to Managing Director Raoul Restucci. "These are very large investments, which will probably total in excess of $10 billion over the next 5-10 years," the Managing Director said. (Oman observer)
