Some Producing Oil Fields by size
Currently there are 116 oil fields that produce more than 100,000 barrels of oil per day. These 116 fields produce almost half the world's oil.
Mega oilfields
Middle East - Saudi Arabia
Ghawar mega field
5,800,000 barrels a day (includes Ain Dar, Shedgum, and Uthmaniyah reserves, producing -3.5 million barrels a day) -recoverable reserves are supposedly 115 billion barrels of oil reserves (US billion, 1,000,000,000) 70 billion already produced as at 2000 (range of estimates 95-125 billion barrels) discovered 1948 - commenced (started producing) 1951 - peaked 1981 (at 5,694,000 barrels a day). - Aramco State Oil Company
South Ghawar - Hawiyah and Haradh - commenced production 1996 Ghawar total after 1996 - 5,772,000 barrels a day (2005 IEA report, includes Hawiyah, and Haradh III as part of Ghawar and may also include an unstated ( not published) amount of condensate and natural gas liquids. After 1996 peak - with the new Haradh III field included, but without liquids, have experts estimating 'Ghawar revamped' (reworked) will peak in 2010
Notes - this field, or the most productive part of it, is flagged for the possibility of catastrophic (disastrous) decline within several years due to the aggressive (forceful) extraction methods. The area of highest production has been in North Ghawar, producing at the rate of around 4.5 million barrels a day, but containing only 20% of total (albeit massive) reserves. The rest of this huge field produces naturally at only about 300,000 barrels a day, according to Matt Simmons. “Haradh, for example, currently needs 500,000 barrels of water a day of injected (pumped) into it to maintain (keep up) a flow rate of 300,000 barrels of oil a day. To sustain (continue) the same production rate as present, the less free-flowing (thicker oil) middle and southern part of Ghawar will have to double the number of drilling rigs in place by the end of 2006, and by 10 years from now, will need 2,000 drilling rigs in place, a number close to the current total of rigs in the world.”;
South America - Mexico - offshore
Cantarell
complex (includes Ajkal, Nohoch, Chac, Kutz and Sihil)- around 1,900,000 barrels a day (2 million barrels a day in 2005,1.7 million bpd expected by end of 2006) - first field discovered 1976 - production commenced 1979 - peaked, pressurized, re-peaked - production now declining at an unusually fast about 12%-14% a year.
Notes - this field is flagged for the possibility of catastrophic decline within 3 years due to the aggressive extraction methods, including water and nitrogen injection.
Middle East - Saudi Arabia - offshore
Safaniya
1,728,000 barrels a day (IEA 2005 report on 2004 production) - 28 API heavy oil - peaked 1981 (1,544,000 barrels a day, but see IEA supposed 2004 production)
South America - Venezuela - coastal
Bolivar
contains 14-36 Gigabarrels (billion barrels) ultimately recoverable reserves of oil.
Middle East - Kuwait
Burgan
1,700,000 barrels a day - proven reserves 15 billion barrels - peaked (current production about 14% less than peak)
East Eurasia - China
Da Qing
1,000,000 barrels a day - peaked 2003.
Central Eurasia - Russia
Samotlor mega field
Smatlor South reserves 44.6 billion barrels oil equivalent in place, up to 47% may be recoverable, and 35% has been recovered to date -TNKBP
Smatlor North reserves 8.1 billion barrels oil equivalent in place, up to 25% may be recoverable, and 18% has been recovered to date - peaked, production declining at about 9% per year - TNKBP
Very Large oilfields

East Eurasia Russia
Sakhalin basin area 1 - Chayvo field - commenced 2005 -250,000 barrels a day (anticipated year end 2006) - reserves 2.3 billion barrels oil
Africa - AngolaPlutonio -
Deepwater offshore - 220,000 to 240,000 barrels a day - peak expected 2007 - BP, Sonangol (Angola State), Sinopec (China State)

Khurais - 150,000 barrels a day in the 80's, currently mothballed (Slang for stopped production) - reserves "multiple billion barrels" - commenced 1964, mothballed 1980's due to poor flow requiring high investment to 'rework' and extensively pressurize.
