Key reserves

Oil reserves (2021)

5.37 B bbl

Natural gas reserves (2021)

23.00 TCF

Key terms

Proved reserves: — Quantities of crude oil or natural gas that geological and engineering data demonstrate with reasonable certainty are recoverable under existing economic and operating conditions.
Recoverable reserves: — Coal that can be technically and economically extracted with current mining methods at current prices. Excludes inaccessible deposits.
Billion barrels (B bbl): — Unit for oil reserves. One barrel equals 42 US gallons or about 159 litres.
Trillion cubic feet (TCF): — Unit for natural gas reserves. One TCF is roughly 28.3 billion cubic metres.
Million short tons (M ST): — Unit for coal reserves. One short ton equals 2,000 lb or 907 kg.

Crude oil proved reserves

In 2021, Oman had 5.373 billion barrels of proved crude oil reserves. Over the prior decade, those reserves edged lower (-2%).

Natural gas proved reserves

In 2021, Oman held 23.00 trillion cubic feet of proved natural gas reserves. Reserves declined significantly over the prior decade (-23%).

The bottom line

Oman held meaningful stocks across oil and gas, which gave it flexibility across global energy markets. Reserve estimates had trended lower, reflecting extraction outpacing new discoveries.
