Production from Claymore

The Claymore conventional oil field recovered 98.85% of its total recoverable reserves, with peak production in 1984. The peak production was approximately 100.51 thousand bpd of crude oil and condensate and 23.00 Mmcfd of natural gas. Based on economic assumptions, production will continue until the field reaches its economic limit in 2026. The field currently accounts for approximately 1% of the country’s daily output.

Remaining recoverable reserves

The field is expected to recover 7.33 Mmboe, comprised of 6.75 Mmbbl of crude oil & condensate and 3.45 bcf of natural gas reserves.
