Muscat, 1 February 2021: Masirah Oil Limited (“Masirah Oil”) is pleased to announce that production has commenced from the second development well drilled in the Yumna Field. The well was spudded on 10 December 2020 and production commenced on 23 January 2021. The well has been producing at a stabilised rate of 9,000 stb/d of dry oil. The rate is constrained by the size of the downhole Electrical Submersible Pump installed in the well.

Yumna 2 encountered 10 metres of Lower Aruma sandstone with a porosity of 21 per cent, proving that the good quality reservoir sand is extensive to the north of Yumna 1; the permeability is about 2,000 md. The reservoir pressure depletion over the first year of production is around 100 psi, confirming that excellent pressure support is provided by a strong aquifer.

The third production well, Yumna 3, was spudded on 20 January 2021, targeting a crestal location in the field to the east and up-dip from the discovery well GAS-1.

The production facilities on the Yumna Mobile Offshore Production Unit (MOPU) are being upgraded to double the liquid processing capacity in order to accommodate production from the three Yumna wells. The upgrade is scheduled to be completed by the end of the first quarter of 2021.

On completion of Yumna 3, the Shelf Drilling Tenacious Jack-up rig will relocate to drill the Zakhera prospect which is located about 12 km to the south of the Yumna Field. This exploration well is targeting a structure that looks similar to the Yumna Field.
