Map of the Mid-continent oil field. The Mid-continent oil field is a broad area containing hundreds of oil fields in the U.S. states of Arkansas, Kansas, Louisiana, New Mexico, Oklahoma and Texas. The area, which consists of various geological strata and diverse trap types, was discovered and exploited during the first half of the 20th century.
The term "United States," when used in the geographic sense, refers to the contiguous United States (sometimes referred to as the Lower 48, including the District of Columbia not as a state), Alaska, Hawaii, the five insular territories of Puerto Rico, Northern Mariana Islands, U.S. Virgin Islands, Guam, American Samoa, and minor outlying possessions.

Shaded relief map of the United States, showing 10 geological provinces. The richly textured landscape of the United States is a product of the dueling forces of plate tectonics, weathering and erosion. Over the 4.5 billion-year history of the Earth, tectonic upheavals and colliding plates have raised great mountain ranges while the forces of ...

The geology of North America is a subject of regional geology and covers the North American continent, the third-largest in the world. Geologic units and processes are investigated on a large scale to reach a ...
Watersheds of North America are large drainage basins which drain to separate oceans, seas, gulfs, or endorheic basins. There are six generally recognized hydrological continental divides which divide the continent into seven principal drainage basins spanning three oceans (Arctic, Atlantic and Pacific) and one endorheic basin
The Permian Basin is the largest petroleum-producing basin in the United States and has produced a cumulative 28.9 billion barrels of oil and 75 trillion cubic feet of gas. In early 2020, over 4 million barrels of oil a day were being pumped from the basin. Eighty percent of estimated reserves are located at less than 10,000 feet (3,000 m) depth.
The United States Geological Survey adapted Fenneman's scheme in their Physiographic division of the United States. [7] The "section" is somewhat larger than the hydrographic definition. The Great Basin culture area , or indigenous peoples of the Great Basin , is a cultural classification of indigenous peoples of the Americas and a cultural ...
The Illinois Basin has produced more than four billion barrels of petroleum. [6] Major oil production began in 1905, and from 1907 through 1912, the basin was the third-most oil productive area in the United States. Oil production peaked in 1908 at 34 million barrels per year, and declined steadily to 5 million barrels in 1933.
