Masirah Oil starts production from its offshore Block 50

3 Feb 2021

Masirah Oil Limited announced that hydrocarbons production has commenced from its second development well drilled in the Yumna field in Block 50 offshore Oman.

The well was spudded on December 10, 2020 and production commenced on January 23, 2021. ‘The well has been producing at a stabilised rate of 9,000 barrels per day (bpd) of dry oil. The rate is constrained by the size of the downhole electrical submersible pump installed in the well,’ Masirah Oil said in a statement released by its Singapore-based parent Rex International Holding Limited.

According to the company, Yumna 2 well encountered 10m 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.

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

Masirah Oil said the production facilities on the Yumna Mobile Offshore Production Unit 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, the company added.

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

Dan Broström, executive chairman of Rex International Holding, said, “We are pleased that the Yumna 2 well was 

developed successfully and is now already producing 9,000 bpd. When Yumna 1 resumes production and the new Yumna 3 is completed, we are looking forward to steady production from the three Yumna wells. 

We are therefore in the process of upgrading the present maximum liquid processing capacity to handle up to 30,000 bpd. 

We will keep the market updated as soon as we have the results from Yumna 3 and the Zakhera exploration well.”
