Rex International Holding Limited has released an updated Qualified Person’s Report (QPR) for the Yumna Field, Block 50 Offshore Oman, revealing a significant increase in estimated reserves. The report, prepared by Exceed Torridon Ltd, indicates a 27% rise in base reserves (2P) from the previous estimate, now standing at 4.7 million stock tank barrels (MMstb) as of 31 December 2024.
The QPR, approved by Ian Mills, Managing Director of Exceed Torridon, and Stephen Hayhurst, a Qualified Person with over 36 years in the oil and gas industry, highlights the successful optimisation of the depletion plan as a key factor in the revised estimates. The report also notes the addition of new development wells, including Yumna-6, Yumna-7, and Yumna-8, which are expected to further enhance production capabilities.
The Yumna Field, initially discovered in December 2013, has seen continuous development and production since the first well, Yumna-1, was spudded in December 2019. The field has produced approximately 9 MMstb to date, with ongoing efforts to optimise production rates and expand the field’s capacity.
The updated reserves estimate underscores the potential for further development in the Yumna Field, with plans to commence drilling of Yumna-6 in the second half of 2025. This strategic expansion aims to tap into reserves in the northwest and northeast of the field, ensuring sustained production and growth for Rex International.
