Production from Nene Marine

The Nene Marine conventional oil field recovered 20.98% of its total recoverable reserves, with peak production expected in 2022. The peak production was approximately 39.71 thousand bpd of crude oil and condensate and 57 Mmcfd of natural gas. Based on economic assumptions, production will continue until the field reaches its economic limit in 2045. The field currently accounts for approximately 12% of the country’s daily output.

Remaining recoverable reserves

The field is expected to recover 196.05 Mmboe, comprised of 158.43 Mmbbl of crude oil & condensate and 225.71 bcf of natural gas reserves. Nene Marine conventional oil field reserves accounts 0.04% of total remaining reserves of producing conventional oil fields globally.
