Casper, Wyoming, United States

🇺🇸 Casper is a city in, and the county seat of, Natrona County, Wyoming, United States. Casper is the second largest city in the state. Casper is nicknamed "The Oil City" and has a long history of oil boomtown and cowboy culture, dating back to the development of the nearby Salt Creek Oil Field. Casper is located in east-central Wyoming at the foot of Casper Mountain, the north end of the Laramie Mountain Range, and along the North Platte River.

Economy Casper is a regional centre of banking and commerce. After the discovery of crude oil in the region during the 1890s, Casper became the regional petroleum industry centre. Oil has figured prominently in its history from nearly the outset. Oil was first discovered in the famous Salt Creek Oil Field in 1889, approximately 40 miles (64 km) north of Casper; the first refinery in Casper was built in 1895. The city has featured a refinery ever since, although various refineries have been built and closed over the years. As recently as the early 1980s, the city was near or home to three refineries. The surviving one, operated by Sinclair Oil Corporation, is located nearby in Evansville. Development of Wyoming coal and uranium fields in recent decades has helped Casper continue its role as a centre in the energy industry.
