Production from Magnus

The Magnus conventional oil field recovered 97.36% of its total recoverable reserves, with peak production in 1994. The peak production was approximately 143.58 thousand bpd of crude oil and condensate and 109 Mmcfd of natural gas. Based on economic assumptions, production will continue until the field reaches its economic limit in 2028. The field currently accounts for approximately 1% of the country’s daily output.

Remaining recoverable reserves

The field is expected to recover 27.62 Mmboe, comprised of 19.73 Mmbbl of crude oil & condensate and 47.36 bcf of natural gas reserves. Magnus conventional oil field reserves accounts 0.01% of total remaining reserves of producing conventional oil fields globally.
