The data in this post was released today by the Oil & Gas Authority. It is published three months in arrears.
Small fall in daily production
- Daily UK onshore oil production fell slightly in June 2021, compared with the month before.
- But it remained above the 31-year low reached in April 2021.
- June 2021 onshore oil was 94.4% of the level in June 2020 and 88.7% that of June 2019.
The ranking of the top four fields (Wytch Farm, Welton, Singleton and Stockbridge) has remained unchanged since April 2021.
Wytch Farm, Dorset: The UK’s largest onshore producer saw production (in barrels per day) fall in June compared with May but it was above levels reached in March and April. The field’s share of UK onshore production remained above 84%.
Welton, Lincolnshire: This IGas site saw its fourth consecutive monthly increase in oil production (bopd) since February 2021.
Singleton, West Sussex: Another IGas site, this saw the lowest daily production since October 2020.
Stockbridge, Hampshire: The fourth ranking producing site onshore in the UK , this saw production rise in May but it was still below February and March.
Glentworth, Lincolnshire: June 2021 saw the third consecutive fall in production.
Horndean, Hampshire: Production in June 2021 was 73% that of April 2021.
Whisby, Lincolnshire: Oil production in June 2021 was 158% up on the previous month and reached the highest level for a year.
Horse Hill, Surrey: Production dropped below 100 bopd for the first time since February 2021.
Scampton North, Lincolnshire: This site saw continued falls in production since April 2021
Cold Hanworth, Lincolnshire: Production rose for the third consecutive month, with barrels per day up 133% on March 2021.
Top onshore companies
Perenco (Wytch Farm, Kimmeridge and Wareham) produced more than 85% of UK onshore oil for the third consecutive month in 2021.
Second placed IGas, with 27 sites, saw its share continue to fall. It was down at 12.27%, the lowest proportion of UK onshore oil produced by the company since January 2021.
Egdon Resources, which produced 0.04% of UK onshore oil, has seen its share fall continuously this year, from 0.26% in January to 0.04% in June. here was no production at Fiskerton Airfield in June and the company’s only formal production was 5bopd from Keddington. It is now the lowest ranking company for onshore oil production. The company’s Wressle site in North Lincolnshire has not yet gone into formal production.
Blackland Park Exploration, at 0.672%, ranked third, had its highest share this year. This is probably because of increased production at Whisby (see above).
UK Oil & Gas plc (Horse Hill), ranked fourth, saw its share fall to its lowest level in 2021, at 0.67%.
Europa (Crosby Warren and West Firsby) was unchanged at 0.31% , the lowest share of 2021. EP UK Investments (Herriard and Humbly Grove) and Onshore Oilfield Services Limited (Farleys Wood) both saw an increased share compared with May 2021.
Angus Energy produced no oil from its sites at Brockham and Lidsey for the 15th consecutive month.
Disposal of formation water is a major expense for the onshore oil industry. The water cut for a field is the ratio of the water produced compared to the volume of the total liquids.
- The water cut in UK onshore wells in June 2021 varied from 1% to 96%.
- Some of the largest producing fields (Wytch Farm and Stockbridge) had the highest water cuts, at more than 90%.
- The water cut at many sites has remained relatively stable in recent months.
- But Whisby saw its water cut fall from 80% in February to 71% in June 2021. Horse Hill has also seen a declining water cut in 2021, from 35% in January to 29% in May and June. UKOG is planning to turn one of its wells (HH2z) into a water injector.
- The water cut at Scampton North has varied in 2021 from a low of 31% in March to a high of 62% in June.
