    Because proven reserves include oil recoverable under current economic conditions, nations may see large increases in proven reserves when known, but previously uneconomic deposits become economic to develop. In this way, Canada's proven reserves increased suddenly in 2003 when the oil sands of Alberta were seen to

    In 1970, local peak production was 10,044 million bbl (1,597 million m 3) per day in November 1970. [8] Total production of crude oil from 1970 through 2006 was 102 billion barrels (16.2 × 10 ^ 9 m 3), or roughly five and a half times the proved reserves over the same timeframe when taking into account the decreasing proved reserves.

    A Probable Mineral Reserve has a lower level of confidence than a Proved Mineral Reserve but is of sufficient quality to serve as the basis for decision on the development of deposit. A Proved Mineral Reserve is the economically mineable part of a Measured Mineral Resource. It includes diluting materials and allowances for losses which occur ...

    Due to constant announcements of shale gas recoverable reserves, as well as drilling in Central Asia, South America, Africa, and deepwater drilling, estimates are updated frequently. Since 2000, some countries, notably the US and Canada, have seen large increases in proven gas reserves due to development of shale gas , but shale gas deposits in ...

    This has been especially true in the United States, where the ratio of proved reserves-to-production has been between 8 years and 17 years since 1920. Many have mistakenly interpreted the result as the number of years before the oil supply is exhausted. Such analyses do not take into account future reserve growth. [2]
