Exploration in Oman's Rub al Khali Basin over the last ten years has delivered excellent full-cycle returns. Key oil and gas-bearing plays are the Precambrian to Cretaceous oil play, and a Paleozoic tight gas play. Returns were driven by the relatively high levels of oil, and by the relatively low levels of sub-commercial discoveries in the mix. The future outlook for exploration also looks positive, with prospective resources into the billions of barrels of oil equivalent for both oil and gas. Oil finds can be quickly and cheaply tied into existing infrastructure, but gas prices will need to be negotiated up in order for explorers to create value from the gas play.
