In April 2010, Saad al-Tureiki, Vice-President for Operations at Aramco, stated, in a news conference reported in Saudi media, that over {{convert|65|Goilbbl|km3}} have been produced from the field since 1951. Tureiki further stated that the total reserves of the field had originally exceeded {{convert|100|Goilbbl|km3}}.<ref>{{cite news

[[Matthew Simmons]], in his 2005 book ''[[Twilight in the Desert]]'', suggested that production from the Ghawar field and Saudi Arabia may soon [[Hubbert peak theory|peak]].<ref name=simmons>{{cite book

When appraised in the 1970s, the field was assessed to have {{convert|170|Goilbbl|km3}} of original [[oil in place]] (OOIP), with about {{convert|60|Goilbbl|km3}} recoverable (1975 Aramco estimate quoted by Matt Simmons). The second figure, at least, was understated since that production figure has already been exceeded.<ref name=simmons/>
