Angus Energy plc has increased production following the commissioning of the new booster compressor at the Saltfleetby gas field in East Lincolnshire.
OPTIMISE
The company said that operations, starting on 11 April, were at a lower suction pressure than the two existing compressors to allow “more pressure drawdown of the wells”.
This also eased the impact of liquid loading in the wells, which had increasingly affected gas flow rates during the first quarter.
“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,” added Angus.
“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.”
Gas sales for Q1 equalled 4.55 million therms in aggregate, a slight decrease from 5.73m therms sold in Q4 2024.
Gas condensate (liquid) production averaged 82 bbl/day, a fall from an average 102 bbl/day in the fourth quarter 2024.
Saltfleetby operational efficiency was 90% for Q1 compared with 94% for Q4 2024.
At the Brockham oil field in Surrey, Angus reported an increase of operational efficiency to 98% compared with 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,” said the company.
“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.”
Lower gas volumes, partially offset by higher gas prices over winter, resulted in a decrease in estimated revenues by around 15% to £5.21m compared with Q3 2024 revenues of £6.12m.
Oil production from Brockham equalled 2,150 barrels in aggregate for January to March 2025, an average of 24 bbl/day, a slight rise from the 2,130 barrels for Q4 2024 with an average of 23 bbl/day.
