According to an April 2015 EIA Report, the Top 100 oil fields as of December 31, 2013, accounted for 20.6 billion barrels of crude oil and lease condensate proved reserves. This represented some 56% of the US total of 36.5 billion barrels.
As a measurement of the boom in oil exploration and production over the last few years, the 2013 total of 36.5 billion barrels was up from 13.9 billion barrels of proved reserves in 2009.
While the EIA report highlights the top 100 fields, this blog post simply lists the Top 10. That Top 10 list has some good news for Texas, which boasts four top ten fields, followed by Alaska (two), the Gulf of Mexico (two), and one each in California and Colorado.
The list below has the name and location of these fields, the estimated 2013 production (in thousands of barrels), and the year the field was discovered:
- EAGLEVILLE (EAGLE FORD SHALE), Texas 238,050 2009
- SPRABERRY TREND AREA,Texas 99,787 1949
- PRUDHOE BAY, Alaska 79,080 1967
- WATTENBERG, Colorado 47,259 1970
- BRISCOE RANCH (EAGLE FORD SHALE), Texas 62,046 1962
- KUPARUK RIVER, Alaska 29,487 1967
- MISSISSIPPI CANYON BLK 778 (THUNDER HORSE), Federal Gulf 15,833 1999
- WASSON, Texas 19,996 1937
- BELRIDGE SOUTH, California 23,703 1911
- GREEN CANYON BLK 699 (ATLANTIS), Federal Gulf 27,346 1998
Even though the current climate of low oil prices has caused a pullback in new shale oil field exploration and production across the US, this list shows that there is plenty of oil in place for when higher oil prices return, allowing production to take off again.
It also shows that Texas has the bragging rights. The state that claimed the industry-changing Spindletop gusher in the early 1900s also claims the industry-changing Eagle Ford Shale finds of the 2000s. The Eagleville field alone accounted for 37% of the total production of the Top 10 fields combined in 2013.
