The Bakken Field in North Dakota and Montana is the largest producing shale oil reserve. The field has layers of dense, oil-bearing rock about two miles underground. The field is roughly the size of West Virginia and, as of December 2012, produced 770,000 barrels of oil a day.

Shale-focused peer Pioneer Natural Resources (NYSE:PXD), ranked as Texas' second-largest oil producer in 2016, pulling 167,006 barrels per day from the Eagle Ford and Permian formations -- 6.3% of Texas' production. It was also the tenth-largest natural gas producer in the state, accounting for 2.3% of gas output. field boundaries (2007), resources (2006), reserves and production (2006), and top 100 methane emitting coal mines (2005) Shapefile; U.S. oil and gas field maps: The following national map portrays the location of fields identified as being among the 100 largest oil and/or 100 largest gas fields in the U.S. on December 31, 2009. The Permian consists of several shale plays that overlay the Permian Basin, including the Avalon, Wolfcamp, Bone Spring Field, Spraberry Field, and Yeso Oil Play. Eight operators account for 70% of drilling in the Permian: Pioneer Natural Resources, Concho Resources, Apache, Oxy, Energen, Sandridge, Cimarex, and EOG. The Unocal oil-shale plant was the last major project to produce shale oil from the Green River Formation. Plant construction began in 1980, and capital investment for constructing the mine, retort, upgrading plant, and other facilities was $650 million.

The U.S. Energy Information Administration provides an interactive map showing the major tight oil and shale gas plays in the lower 48 states.. Tight oil and shale gas are two of the main types of "unconventional" oil and gas resources, and played an important role in the early-21st-century resurgence in domestic production of oil (beginning around 2009) and natural gas (beginning around 2006). In just the first seven months of 2018, the total monthly decline rate from these top shale fields increased by 26%. These massive decline rates are the very reason the shale oil and gas companies are struggling to make money. A perfect example of this is PXD, Pioneer Resources. Pioneer is the largest shale oil producer in the Permian.

Changes in the top 100 Oil Fields In 2009, the United States had 22.3 billion barrels of crude oil and lease condensate proved reserves, and its top 100 oil fields had 62.3% of that total, or 13.9 billion barrels of proved reserves. In 2013, the United States had 36.5 billion barrels of crude oil and lease In 2007, shale gas fields included the #2 (Barnett/Newark East) and #13 (Antrim) sources of natural gas in the United States in terms of gas volumes produced. The number of unconventional natural gas wells in the US rose from 18,485 in 2004 to 25,145 in 2007 and is expected to continue increasing until about 2040.

Samotlor is Russia’s largest oil field, producing nearly 3 million barrels per day at its peak in the 1980s. Rosneft, Russia’s largest oil company, owns and operates the Siberia-based field, which saw profitability fall as it took nearly 95 barrels of water to produce five of oil.

Major oil shale deposits are located in the Democratic Republic of Congo (equal to 14.31 billion metric tons of shale oil) and Morocco (12.3 billion metric tons or 8.16 billion metric tons of shale oil).

Nearly one third of the United States’ crude already comes from the Permian, making it the largest shale-oil producing region in the country. While numerous studies have been conducted on the Permian's half-dozen sub-basins and their many overlapping formations, Large basins such as the Western Gulf Basin, the Permian Basin, the TX-LA-MS Salt Basin and the Appalachian basin contain some of the largest oil fields in the United States, putting upwards of 290 billion cubic feet of oil alone, with some areas in the Permian, Western Gulf and Appalachian basins putting out that number in cubic feet all by themselves.
