New flowline set to boost operations at Yumna Field

MUSCAT, FEB 11

Masirah Oil Limited (MOL) has successfully installed and commissioned a new flowline at its Yumna Field in Block 50 offshore Oman, marking a key milestone in the company's ongoing efforts to enhance production efficiency. The new flowline became operational in late January 2025, allowing the seamless transfer of produced fluids from the field.

The installation follows previous infrastructure upgrades at Yumna, including the commissioning of a bulk water system and gas-lift systems in November 2024. These enhancements are designed to improve operating efficiency and optimize production capacity at the offshore complex.

MOL reported that its gross production from the Yumna Field in January 2025 averaged 2,333 stock tank barrels per day (stb/d), demonstrating stable output following the commissioning of the new flowline.

The latest installation is particularly significant, as it addresses past operational challenges at the field. In October 2023, production was temporarily halted due to damage in the internal pressure liner of a larger flowline installed a month prior. That flowline was introduced to replace a flexible line that had developed a leak but was later found to have compromised hose integrity, leading to a production shutdown until December 2023.

The new flowline is expected to enhance operational resilience and minimise risks associated with fluid transportation. It also supports MOL’s broader strategy to maximise hydrocarbon recovery from the Yumna reservoir. As part of this strategy, MOL launched a major offshore drilling campaign in April 2024, partnering with Northern Offshore Ltd. to deploy the Energy Emerger jack-up rig. The campaign includes the drilling of a new in-field well and workovers of two existing production wells.

Since production began in February 2020, Yumna has been a core asset in MOL’s portfolio. With MOL holding a 100 per cent interest in Block 50 and with continuous investment in drilling and infrastructure upgrades, the company is positioning itself for sustained production growth in Oman’s offshore sector.
