UK onshore oil and gas production in charts – January 2023

DrillOrDrop’s review of the latest UK onshore production data for January 2023 reveals another record month for flaring at oil fields. For the first time in this series of articles, we’ve added data on onshore gas production.

Key figures

Daily production: Oil: 14,121 barrels per day (bopd). Gas: 9 million standard cubic feet per day (mmscf/d)

Weight: Oil: 57,446 tonnes. Gas: 6,995 tonnes.

Volume: Oil: 69,594 m3. Gas: 9,078 thousand cubic meters (ksm3)

Onshore contribution to UK total production: 1.92% of total oil and 0.8% of gas

Volume of flared gas at UK onshore oilfields: 1,193 ksm3

Volume of vented gas at UK onshore oilfields: 128 ksm3

The data in this post was compiled and published by the North Sea Transition Authority (NSTA) from reports by oil companies. This is published about three months in arrears. All the charts are based on the NSTA data.


Daily production

  • Daily oil production dropped from a record high for 2022 in December – but remains above 14,000 bopd.
  • Daily gas production remained stable for the fourth month in a row at 9 mmscf/d.

Volume and weight

  • Oil volume and weight fell nearly 4% in January 2023, compared with December 2022 but remained higher than the six-month low in November 2022.
  • Gas weight and volume was also down nearly 4%, compared with December 2022. January gas volume and weight were the lowest since September 2022.

Contribution to UK production

  • Onshore oil and gas had a smaller contribution to total UK oil in January 2023, compared with December.
  • Both were higher than at the same time a year ago.

Flaring and venting

  • Flaring from onshore oil fields was a record high in January 2023 for the previous 12 months.
  • The volume of vented gas in January 2023 was down on December 2022 but was the third highest monthly total in the previous 12 months.
