Masirah Oil completes drilling campaign in Oman

MUSCAT, January 10, 2023 – Masirah Oil has completed its latest drilling campaign on Block 50 offshore Oman, the Singaporean-owned E&P company announced on Monday.

The Q4 2022 drilling campaign consisted of a workover of the Yumna-3 well – including replacing the electrical submersible pump – and the drilling of the Yumna-4 exploration well.

Production at the Yumna-3 well has risen from 3,690 boepd to 4,050 boepd with the new equipment.


The Yumna-4 well successfully hit 9.6 metres of net oil pay at the Aruma level, with production flows of 4,050 boepd.

The objective of drilling the fourth well was to study the eastern extension of the Aruma reservoir and an exploration target at greater depths and northeast of the field.

A 16.5-metre core sample is being sent for analysis for further evaluation of the site.

Masirah Oil is a subsidiary of Rex International that owns 100% shares in Oman’s Block 50.
