Oman is the largest oil and natural gas producer in the Middle East that is not a member of the Organization of the Petroleum Exporting Countries.

Total reserves of natural gas in Oman at the end of 2019 were estimated to be 23.8 trillion cubic feet, 53.7 per cent of which is the estimated reserve of PDO, followed by BP (Khazzan and Ghazeer) with 41 per cent, and 5.3 per cent of other companies. Khazzan is currently producing around one billion cubic feet per day (bcf/d) as of June 2020, according to the Ministry of Energy and Minerals (MEM). BP expects production to boost to 1.5 bcf/d when the Ghazeer development, representing Phase 2 of BP Oman’s multi-year development, comes on stream early in 2021.
