Beryl is a producing conventional oil field located in shallow water in the UK and is operated by Apache Beryl I. The field is located in block 9/13a ALL, 9/13b ALL, 9/13c ALL, and 9/13d ALL, with water depth of 1,266 feet.

Three expansion projects are associated with the Beryl conventional oil field, namely Beryl Infill Development Phase 2, Beryl Infill Development Phase 1 and Beryl Infill Development Phase 3. The expansion projects are currently in the feasibility stage, targeting start-up during 2023 – 2024.

Field participation details

The field is owned by Apache and Harbour Energy.

Production from Beryl

The Beryl conventional oil field recovered 97.54% of its total recoverable reserves, with peak production in 1992. The peak production was approximately 105.3 thousand bpd of crude oil and condensate and 363 Mmcfd of natural gas. Based on economic assumptions, production will continue until the field reaches its economic limit in 2031. The field currently accounts for approximately 1% of the country’s daily output.

Remaining recoverable reserves

The field is expected to recover 33.6 Mmboe, comprised of 24.65 Mmbbl of crude oil & condensate, 52.81 bcf of natural gas reserves and 0.15 Mmbbl of natural gas liquid reserves. Beryl conventional oil field reserves accounts 0.01% of total remaining reserves of producing conventional oil fields globally.
