Singapore-based Rex International said a second oil production well is on stream at the offshore Yumna field in Oman, and a third well has recently spudded.

The Yumna-2 well in Block 50 came on line on 23 January 2021, and has been producing at a stabilised rate of 9000 barrels per day of oil, constrained by the size of an electrical submersible pump.

Yumna-2 hit 10 metres of good-quality Lower Aruma sandstone, while there is excellent pressure support provided by a strong aquifer.

A third production well, Yumna-3, spudded on 20 January 2021 using Shelf Drilling's jack-up Tenacious.

The liquids processing capacity on the Yumna mobile offshore production unit is being doubled to 30,000 bpd in order to accommodate the three Yumna wells, and the upgrade is scheduled to be completed by the end of the first quarter of 2021.

On completion of Yumna-3, the same jack-up rig will relocate to drill the Zakhera exploration prospect 12 kilometres to the south of the Yumna field.

"When Yumna-1 resumes production and the new Yumna-3 is completed, we are looking forward to steady production from the three Yumna wells,"said Dan Brostrom, executive chairman of Rex. "We will keep the market updated as soon as we have the results from Yumna 3 and the Zakhera exploration well.”

Rex's subsidiary Masirah Oil owns 100% of Block 50.
