Delaware Basin Data, History & Stats
This guide provides information about the Delaware Basin, oil and gas data, history, top operators and other facts.
The Delaware Basin, as part of the larger Permian Basin, became the most prolific oil-producing region in the United States, and perhaps the most important oilfield in the world today.
The Delaware Basin’s prominent role in the Permian Basin has made it a crucial player in the energy sector, attracting substantial investment and attention from the oil and gas industry.
Delaware Basin: Subbasin of the largest oil-producing region in the US.
The region has been producing for nearly a century and still contains massive resources of oil and gas. In April of 2022, The Permian Basin accounted for 43.6% of oil production within the U.S. and nearly 15% of gas production.
What is the Delaware Basin?
The Delaware Basin is a geological province located in the southwestern United States, stretching across parts of West Texas and southeastern New Mexico. It is part of the larger Permian Basin, one of the most prolific oil and gas regions in the world.
The Delaware Basin covers an extensive area of approximately 10,000 square miles (26,000 square kilometers). It spans across several counties in Texas, including Loving, Reeves, Ward, Winkler, and Culberson, as well as portions of southeastern New Mexico, including Lea and Eddy counties. Major cities within or near the basin include Midland and Odessa in Texas and Carlsbad in New Mexico.

The Delaware Basin: History, Data and Facts
The Delaware Basin has a rich geological and human history that spans hundreds of millions of years. Formed through complex geological processes, the basin’s origins can be traced back to ancient tectonic activity before the time of the dinosaurs, in the Permian period. A complex interplay of continental collision and oceanic subduction along North America’s southern and western edges caused mountain and basin formation in what are known today as the “Ancestral Rockies.” Into the Delaware basin poured sediment and organic matter that millions of years later became hydrocarbons.
Today, the Delaware Basin stands as one of the most productive oil and natural gas regions in the United States, contributing to the nation’s energy supply and playing a vital role in the economy of the surrounding regions.
Delaware Oil Production
When and how did it start?
Oil production in the Delaware Basin has a rich history that dates back to the early 1900s. Initial exploration activities in the region targeted shallow oil reservoirs. However, a significant milestone in the basin’s history occurred in 1926 with the discovery of the Big Lake Oil Field in Reagan County, Texas. This discovery marked the first major oil field in the Delaware Basin and ignited the region’s oil production boom.
Over the years, advancements in drilling technology, particularly the development of horizontal drilling techniques, transformed the basin’s oil production capabilities. Horizontal drilling, combined with hydraulic fracturing methods, enabled operators to tap into the vast hydrocarbon resources locked within the basin’s shale formations.
Although the unconventional revolution came later to the Delaware Basin than it did in the Bakken or Eagle Ford, the Delaware has become the highest-producing unconventional oil region in the world. At around 3 million barrels of oil a day, the Delaware would be the tenth-highest producing country in the world on its own.

Delaware Gas Production
When and how did it start?
Natural gas production in the Delaware Basin has a parallel history alongside oil production. Gas wells were drilled as early as the 1920s, and natural gas has been produced in the region primarily for local and regional consumption. However, the true uprise in natural gas production came with the advancement of unconventional oil developments. In the Delaware, the vast majority of the gas is “associated gas” produced as a byproduct of oil production.
Alongside its ~3 million barrels of oil a day, the Delaware produces >12 billion cubic feet of gas a day, nearly as much as the Haynesville. This tremendous supply of gas has contributed significantly to the rise in the US’s domestic production and ability to ship LNG internationally. Alongside the rise in dry natural gas production, the Delaware Basin also experienced a surge in natural gas liquids (NGLs) production.
NGLs, such as ethane, propane, and butane, are extracted from the natural gas stream and have diverse industrial applications. The growth of natural gas production in the Delaware Basin has also led to the development of infrastructure for natural gas exports. Pipelines and liquefied natural gas (LNG) export facilities have been constructed to transport and export natural gas from the basin to domestic and international markets.

Delaware Basin formations
The Delaware Basin is home to several major geological formations, each with its own unique characteristics and significance. Here are some of the notable formations found in the Delaware Basin.
Delaware Mountain Group
Leonardian Series
Avalon Shale
Bone Spring Formation
Wolfcamp Formation
Depositional Environment on The Delaware Basin
In addition to its primary hydrocarbon resources, the Delaware Basin is known to contain various other natural resources. Sylvite, Langbeinite, Halite (rock salt), Sulfur, and Uranium have been identified within the basin.
Sylvite, discovered in 1925, has been utilized for the production of potassium salts, commonly known as Potash. Halite, a byproduct of potash mining, has also been extracted. These minerals were deposited as evaporites after the Permian seas that formed the Wolfcamp and Bone Spring formations dried up, leaving behind thousands of feet of mineral-rich strata. Notably, the Carlsbad area in New Mexico has served as a prominent potash district, supplying a significant portion of the potassium produced in the United States.
Due to the strategic importance of Potash to fertilizer supply, the federal government has protected “Designated Potash Districts”. In these areas, oil and gas operators must follow more stringent surface regulations to ensure that both hydrocarbon and potassium resources can be responsibly developed.
