- Daily production: 14,070 barrels of oil per day (bopd)
- Weight: 57,122 tonnes
- Volume: 69,346m3
- Volume of onshore as a proportion of UK total oil production: 1.88%
The data in this post was compiled by the Oil & Gas Authority (OGA) from data reported by oil companies. It is published three months in arrears. All the charts are based on OGA data
Small fall in daily production
- Daily production fell slightly in July 2021, compared with the month before
- But it was still above the 31-year low recorded in April 2021.
- July 2021 daily production was 93.8% of that in July 2020 and 83% of July 2019
Volume and weight up slightly
- Volume and weight were both up compared with June 2021, perhaps reflecting an extra day in the month. But both measures were 93% down on the same month in 2020 and 87% down on that in July 2019.
- Volume remained below 70,000m3 for the second month
- Weight was below 60,000 tonnes for the sixth successive month
Fall in proportion of total onshore production
- Lowest contribution to total UK oil production since March 2021
The ranking of the top four fields (Wytch Farm, Welton, Singleton and Stockbridge) remained unchanged for the fourth consecutive month.
Daily production from Britain’s largest onshore field in Dorset was down for the second month, from 12,185bopd in May 2021 to 11,812 in July. The was the second lowest production rate for a year.
Production at IGas’s Welton site in Nottinghamshire remained above 400 barrels a day but was down 30 barrels a day in July 2021 (433bopd) compared with June (463 bopd).
Daily production rates at this IGas site in West Sussex seem to have recovered after a drop in June 2021 and almost took rates back above 400bopd. The figure for July 2021 was 31bopd above the level in the same month a year before.
IGas’s Stockbridge site in Hampshire achieved its highest daily production rate since March 2021.
July 2021 saw a big jump compared with the month before, up from 120bopd to 157bopd.
The Humbly Grove field in Hampshire returned to production levels near those last seen in February 2021. Barrels per day were up from 27 in June to 122 in July. The improvement took the field to sixth in the onshore ranking, compared with 21 in June.
Horse Hill remained below 100bopd for the second month. July 2021 was the lowest production rate since December 2020.
The site in Surrey dropped another two places in the rankings to 10th. It has fallen from fourth in May 2020 after Wytch Farm, Welton and Singleton.
Daily production of formation water has continued to fall at Horse Hill, down to 37 barrels a day in July 2021, compared with a peak of 54 barrels a day in January 2021. Gas flaring was the lowest volume in July 2021 for seven months.
This IGas field in Lincolnshire continued its recent sporadic production pattern. In July 2021, barrels per day were almost half the rate in June (32 down from 59).
Another IGas site in Hampshire, Goodworth made it into the top 20 for the first time this year. Daily production and oil volumes were up slightly.
- Perenco Oil & Gas produced 84.7% of UK onshore oil in July 2021, mostly from Wytch Farm. This was down slightly on June 2021 (85.80%).
- The second largest producing company, IGas, was responsible for 12.5% of UK onshore production, from 26 fields.
- EP UK Investments was the third placed producer, on 0.87%, from just one site, Humbly Grove.
- Egdon Resources, which failed to get planning permission this week for production from the Biscathorpe well in Lincolnshire, produced just 0.12% of UK onshore oil production in July 2021. Its figures do not include Wressle, in North Lincolnshire, which is currently undergoing appraisal. The company has said the well has produced at rates equivalent of 500-800 barrels of oil per day during tests.
13 onshore oil fields had no production in July 2021. They included:
- Both Angus Energy’s oil fields at Brockham in Surrey and Lidsey in West Sussex for the 16th consecutive month. Angus Energy is preparing to apply for planning permission to referorate and produce from the BRX4
- Egdon Resources’ fields at Kirklington, Dukes Wood, Waddock Cross, Fiskerton Airfield. Egdon said yesterday it planned to develop the Waddock Cross site with a possible new horizontal well and repurpose wells at Dukes Wood and Kirklington for geothermal energy
- IGas fields at Avington, Egmanton, Newton on Trent, Nettleham, Scampton and South Leverton. IGas was refused planning permission for an extension to the life at Avington and said in January 2021 that it had appealed but there’s been no news about the outcome.
