In 2015 ExxonMobil added 1 billion barrels of oil equivalent of proved oil and gas reserves for a total of 24.8 billion.
The corporation replaced 67% of production including a 219% replacement ratio for crude oil and other liquids, said the company. This was a direct result of new developments and extensions of existing fields, including a major discovery in offshore Guyana.
Last year the company added reserves in Abu Dhabi, Canada, Kazakhstan and Angola.
