Booster Compressor Successfully Commissioned

First Quarter 2025 Production and Operations Update

·    Booster compressor successfully commissioned on 11 April 2025.

·    Production from the Saltfleetby Field in the First Quarter of 2025 was 411 million standard cubic feet of natural gas and 7,381 barrels of gas condensate.

·    Gas sales of 4.55 million therms were achieved in the Quarter from the Saltfleetby Field.

·    The Brockham Field produced 2,150 barrels of crude oil during the Quarter.

·    Estimated revenues of £5.32m for the Quarter.

Booster Compressor Update

The new booster compressor at the Saltfleeby Gas Field commenced operation on 11 April 2025. The compressor operates at a lower suction pressure than the two existing compressors at the field, allowing more pressure drawdown of the wells and helping to alleviate the impact of liquid loading in the wells, which has been increasingly impacting gas flow rates in the last three months. The introduction of the booster compressor has resulted in an 18% increase in production compared with the average production for the first 10 days of March and a 15% increase compared to average daily production in March. Work is continuing to optimise plant and well performance with the new compressor, with the aim of further improving and stabilising gas flow rates from the three wells in the field.

Production and Operations Update

Gas sales from the Saltfleetby Field equalled 4.55 million therms in aggregate for the months of January, February and March 2025, compared to 5.73 million therms sold in the fourth quarter of 2024. First quarter 2025 production equates to an average of 1.52mm therms per month (1.91 mm therms per month in the fourth quarter of 2024). Gas condensate (liquid) production averaged 82 bbl/day, against an average of 102 bbl/day in the fourth quarter 2024. Saltfleetby operational efficiency was 90% for the Quarter compared to 94% for the previous Quarter.  Brockham operational efficiency was 98% for the Quarter compared to 90% for the previous Quarter.

Lower production at Saltfleetby this first quarter reflects the impact of cold weather on well and plant performance in January and the increasing effect of liquids, mainly condensate, restricting gas flow in the 3 wells in the field. The introduction of the booster compressor will reduce well head pressures and increase gas flow rates and gas velocities from each of the wells and assist in the lifting of liquids to surface and improve the stability of production.

Estimated revenues of £5.21m are down c.15% compared to third quarter revenues of £6.12m, with lower gas volumes being partially offset by higher gas prices over the winter months. As previously announced, legacy hedging volumes will remain at 1.25m therms per month until they roll off in June 2025.

Oil volumes produced from the Brockham Field equalled 2,150 barrels in aggregate for the months of January, February and March 2025, an average of 24 bbl/day, compared to 2,130 barrels for the fourth quarter of 2024 averaging 23 bbl/day.
