Oman's state-controlled Petroleum Development Oman (PDO) plans to heat up its oil wells in the central and southern areas of the Sultanate as part of a new technique designed to maximise hydrocarbon recovery, Emirates Business has reported. "PDO is among the global leaders in implementing thermal enhanced oil recovery technologies. Later this year the company will commence a ground-breaking project to inject steam into the reservoir at Qarn Alam," the firm said in a statement.
