West Texas
West Texas encompasses the vast, arid territory stretching from the Permian Basin around Midland-Odessa westward through the Trans-Pecos region to El Paso on the Rio Grande, and from the caprock escarpment of the Llano Estacado southward to the Big Bend country along the Mexican border. This enormous region -- covering an area larger than many U.S. states -- is defined by immense distances, sparse population, dramatic desert landscapes, and the oil and gas industry that has shaped its economy and culture for more than a century. The terrain transitions from the mesquite-covered rolling plains of the eastern portion to the Chihuahuan Desert of the Trans-Pecos, with the Guadalupe Mountains, Davis Mountains, and Chisos Mountains providing some of the most striking natural scenery in Texas.
Despite its low population density, West Texas is of enormous economic significance to the state and nation. The Permian Basin produces approximately 6 million barrels of crude oil per day, accounting for roughly 40 percent of total U.S. crude oil output and making it the most productive oil field in the Western Hemisphere. El Paso, the largest city in the region with a population of approximately 680,000 in the city proper and 870,000 in El Paso County, is a major border city, military installation host, and trade gateway. Between these two economic anchors, the landscape is dotted with small ranch towns, oil field supply communities, and the occasional crossroads city that serves as a regional center for vast surrounding areas.
The Permian Basin
The Permian Basin, named for the Permian geological period during which its sedimentary formations were deposited approximately 250 to 300 million years ago, is the most significant oil-producing region in the Western Hemisphere and one of the most important energy basins in the world. The basin extends across portions of West Texas and southeastern New Mexico, covering approximately 86,000 square miles, with the most productive areas concentrated in the Texas counties surrounding Midland and Ector (Odessa).
Commercial oil production in the Permian Basin dates to the 1920s, and the region has experienced multiple boom-and-bust cycles driven by fluctuating oil prices and evolving extraction technologies. The most dramatic recent transformation occurred with the development of horizontal drilling and hydraulic fracturing (fracking) techniques beginning in the late 2000s, which unlocked vast reserves of oil and natural gas trapped in tight shale and carbonate formations that were previously uneconomical to develop. This technological revolution -- primarily targeting the Wolfcamp, Spraberry, and Bone Spring formations -- transformed the Permian Basin from a mature, declining oil province into the fastest growing production basin in the world.
The economic impact of Permian Basin production is staggering. The basin's output generates tens of billions of dollars in annual revenue for production companies, creates direct employment for more than 100,000 workers in the Midland-Odessa metropolitan area alone, and produces severance tax revenue that is a significant source of funding for the State of Texas. Midland has been repeatedly identified as having the highest per-capita income of any metropolitan area in Texas, with median household incomes significantly above state and national averages. However, the boom-driven economy also creates severe challenges: housing costs in Midland have at times rivaled those of coastal cities, infrastructure (particularly roads) is strained by heavy truck traffic, and the availability of workers in non-oil-related occupations -- teachers, healthcare workers, retail employees -- is chronically limited during boom periods.

El Paso and the Border
El Paso County, with approximately 870,000 residents, sits at the far western tip of Texas on the Rio Grande, across the border from Ciudad Juarez, Chihuahua, Mexico -- a city of approximately 1.5 million people. Together, El Paso and Ciudad Juarez form a binational metropolitan area of more than 2.3 million people, one of the largest international urban agglomerations on any national border. El Paso is geographically closer to the Pacific Ocean than to Houston, a fact that underscores both the immense scale of Texas and El Paso's distinct position within it.
The El Paso economy is anchored by Fort Bliss, one of the largest military installations in the United States by geographic area. Fort Bliss covers approximately 1.12 million acres (1,750 square miles) extending into New Mexico and hosts the 1st Armored Division, the U.S. Army Sergeants Major Academy, and significant training operations. The installation and its associated workforce represent the single largest economic driver in the El Paso region, with more than 40,000 military personnel and civilian employees.
Cross-border manufacturing and trade form the second major pillar of the El Paso economy. The maquiladora industry in Ciudad Juarez -- with hundreds of manufacturing plants producing electronics, automotive components, medical devices, and consumer goods -- is deeply integrated with the El Paso economy through supply chain relationships, logistics operations, and the flow of workers and consumers across the international bridges. The El Paso customs district processes billions of dollars in trade annually, making it one of the busiest ports of entry in the United States.
The University of Texas at El Paso (UTEP) is a major public research university with enrollment exceeding 24,000 students and a majority-Hispanic student body. UTEP has been recognized as a national leader in providing educational access to Hispanic students and has developed significant research programs in border health, geological sciences, and engineering.
The Trans-Pecos
The Trans-Pecos region, extending from the Pecos River westward to the Rio Grande, is the most geographically dramatic and least populated part of Texas. This is the only portion of the state with true mountain terrain: the Guadalupe Mountains (including Guadalupe Peak at 8,751 feet, the highest point in Texas), the Davis Mountains (with Mount Livermore reaching 8,382 feet), and the Chisos Mountains within Big Bend National Park. The landscape is classified as Chihuahuan Desert, characterized by vast open spaces, dramatic rock formations, sparse vegetation, and an austere beauty that attracts visitors from around the world.
Big Bend National Park, encompassing more than 800,000 acres along the Rio Grande where the river cuts through the Sierra del Carmen range, is one of the largest and most remote national parks in the lower 48 states. The park attracts approximately 400,000 visitors annually and is renowned for its geological diversity, dark skies (it has been designated a Dark Sky Park by the International Dark-Sky Association), and challenging backcountry hiking. Big Bend Ranch State Park, the largest state park in Texas at more than 300,000 acres, is situated immediately to the west and offers additional wilderness recreation.
The city of Alpine (population approximately 6,000) serves as the cultural hub of the Trans-Pecos, home to Sul Ross State University and the gateway to Big Bend. The city of Marfa (population approximately 1,700), a former cattle and railroad town, has become internationally known as an arts destination, anchored by the Chinati Foundation (the contemporary art museum established by Donald Judd) and a community of artists, writers, and creative professionals that has transformed the tiny desert town into one of the most culturally surprising places in America.
Infrastructure and Challenges
West Texas faces distinct infrastructure challenges driven by its vast distances, sparse population, and the intense demands of the oil and gas industry. The region's road network, while extensive, is strained by the heavy truck traffic generated by oilfield operations -- a single fracking operation may require thousands of truckloads of sand, water, equipment, and supplies. State Highway 285, which runs through the heart of the Permian Basin, has been called one of the most dangerous roads in the United States due to the combination of oil field truck traffic and two-lane road conditions.
Water is perhaps the most critical long-term challenge facing West Texas. The region is one of the driest in the state, and groundwater from the Ogallala Aquifer (which underlies the High Plains from the Panhandle through parts of the Permian Basin) has been drawn down significantly by agricultural irrigation and municipal use. In the Trans-Pecos, water scarcity is a fundamental constraint on development and population growth. The management and allocation of water resources -- including the waters of the Rio Grande under international treaty obligations with Mexico -- is one of the most complex and consequential policy issues in the region.
