The Eagle Ford Group (also called the Eagle Ford Shale) is a sedimentary rock formation deposited during the Cenomanian and Turonian ages of the Late Cretaceous over much of the modern-day state of Texas. The Eagle Ford is predominantly composed of organic matter-rich fossiliferous marine shales and marls with interbedded thin limestones. It derives its name from outcrops on the banks of the West Fork of the Trinity River near the old community of Eagle Ford, which is now a neighborhood within the city of Dallas. The Eagle Ford outcrop belt trends from the Oklahoma-Texas border southward to San Antonio, westward to the Rio Grande, Big Bend National Park, and the Quitman Mountains of West Texas. It also occurs in the subsurface of East Texas and South Texas, where it is the source rock for oil found in the Woodbine, Austin Chalk, and the Buda Limestone, and is produced unconventionally in South Texas and the "Eaglebine" play of East Texas.

The Eagle Ford was one of the most actively drilled targets for unconventional oil and gas in the United States in 2010, but its output had dropped sharply by 2015. By the summer of 2016, Eagle Ford spending had dropped by two-thirds from $30 billion in 2014 to $10 billion, according to an analysis from the research firm Wood Mackenzie. This strike has been the hardest hit of any oil fields in the world. As of 2016, the spending was, however, expected to increase to $11.6 billion in 2017. A full recovery was not expected any time soon.

Lower Rio Grande Valley (Spanish: Valle del Río Grande), often referred to as the Rio Grande Valley (RGV) of South Texas, is a region located in the southernmost part of Texas, along the northern bank of the Rio Grande. It is also known locally as The Valley, El Valle, or 956 (the area code for the region). It is a region spanning the border of Texas with Mexico located in a floodplain of the Rio Grande near its mouth. The region includes the southernmost tip of South Texas. It consists of the Brownsville-Harlingen and McAllen-Edinburg-Mission metropolitan areas, and the Rio Grande City-Roma and Raymondville micropolitan areas. The area is generally bilingual in English and Spanish, with a fair amount of Spanglish due to the region's diverse history and transborder agglomerations. It is home to some of the poorest cities in the nation, as well as many unincorporated, persistent poverty communities called colonias. A large seasonal influx occurs of "winter Texans" – people who come down from the north for the winter and then return north before summer arrives.
