U.S. oil major Exxon Mobil Corp has revised down its proved crude reserves by 3.3 billion barrels of oil equivalent as a result of low oil prices throughout 2016, a company filing showed on Wednesday.
The de-booking includes the entire 3.5 billion barrels of bitumen reserves at the Kearl oil sands project in northern Alberta, operated by Imperial Oil, a Calgary-based company in which Exxon has a majority share.
