Angus Energy’s gas site at Saltfleetby reached record levels for a second consecutive month since production resumed last year. This helped push the onshore contribution to total UK gas production to its highest level for a year.
Key figures
Daily production: Oil: 13,171 barrels per day (bopd). Gas: 9 standard cubic feet per day (mmscf/d)
Volume: Oil: 62,817m3. Gas: 8,929 thousand cubic meters (ksm3)
Weight: Oil: 51,870 tonnes. Gas: 7,233 tonnes.
Onshore contribution to UK total production: 1.99% of oil and 1.16% of gas
Volume of flared gas at UK onshore oilfields: 1,204ksm3
Volume of vented gas at UK onshore oilfields: 118ksm3

Albury, in Surrey, fell 64% in June 2023, compared with May 2023, down from 458ksm to 165ksm. This was the site’s lowest gas production level since August 2020.


Non-producers
Oil
There was no production at 15 UK onshore oil fields in June 2023. This was three more fields than in May 2023. Additional non-producers this month were Wareham, Crosby Warren and Stainton.
The non-producing fields were:
- Angus Energy: Lidsey, Brockham

- Star Enery (formerly IGas): Avington, Egmanton, Nettleham, Scampton, South Leverton, Stainton
- Perenco: Wareham
- Europa: Crosby Warren
Gas
There was no production reported at 14 UK onshore producing gas fields in June 2023. Production resumed at Florence coal mine vent and Hatfield Moors but stopped at Warsop Main.
The non-producers were:
- Cuadrilla: Elswick
- Egdon Resources: Kirkleatham
- EP UK Investments: Humbly Grove Gas Storage
- Ineos: Airth, Doe Green
- Infinis Energy: coal mine vents at Askern, Bevercotes, Gedling, Kings Mill Hospital, Mansfield, Markham Main, Sherwood and Warsop
- Scottish Power UK plc: Hatfield Moor Gas Storage Injection
Operators
Oil

Perenco, operator of Wytch Farm and Kimmeridge, saw its production and contribution to UK onshore oil drop slightly (down from 40,809 tonnes in May 2023 to 39,211 tonnes in June 2023). This was probably because there was no production at Wareham in June 2023.
Gas

Angus Energy increased its share of onshore gas production, up from nearly 74% in May 2023 to nearly 80% in June 2023.
Infinis Energy, which operators the UK coal mine vents, lost a small amount of production (down from 1,156 tonnes in May to 1,062 tonnes in June 2023) and share of UK onshore gas production.
Total production and share was also down at Star Energy because of falling volumes at Albury.
Scottish Power returned to the table with a small amount of production at Hatfield Moor after no report in May 2023.
