Analysis of the results and returns from exploration in Oman's Mountains Foldbelt Basin over the last decade indicate explorers have struggled to create value, particularly from gas finds. Although most of the acreage is held by independent oil companies, unlike the adjacent Rub al Khali Basin to the south, the small discovery sizes and historically low gas prices have limited returns. Oil discoveries have fared better than gas, with higher relative prices and the facility to tie-in quickly and cheaply to existing infrastructure. Cumulative reserves discovered in the basin now amount to over 2.4 billion boe. Analysis of the yet-to-find volumes and future outlook in the basin is a little more positive as gas developments become more extensive in Oman and gas prices improve. If future explorers can find sufficient volumes, they can expect to achieve good returns on investment.
