Cushing-Drumright Oil Field

In 1912, the discovery well, the Wheeler No. 1 Oil Well came in near Drumright for wildcatter Thomas Baker Slick, Sr. Peak production was in May 1917 at 310,000 barrels per day, accounting for two thirds of the refinable crude oil production in the western hemisphere during that time, and provided twenty percent of the petroleum sold in the United States in 1915-1916. At the peak, 3,090 wells were producing, making the field the most significant production field in Oklahoma. The Drumright Dome, near Drumright, Oklahoma, was the first area to be exploited, followed by the Shamrock Dome. The field stimulated the construction of up to fifty refineries and ten natural gasoline ("casinghead gasoline") plants in the area. Production declined quickly after 1920, dropping to 6,209 barrels per day in 1955. ==Geology==

The Cushing-Drumright Field is defined by four small anticlines, the Dropright Dome, the Drumright Dome, the Shamrock Dome and the Mount Pleasant Dome. The Dropright Dome, named after the former town of Dropright, is the northernmost formation, about in length. The Drumright Dome is named for the town of Drumright, which lies on the west side of the dome. The Mount Pleasant Dome is named for a church on its slope. The Shamrock Dome is close to Shamrock, Oklahoma, and is the southernmost structure. Each structure has a corresponding syncline. The primary production horizons include the Layton Sand, the Wheeler Sand and the Bartlesville Sand. ==History and today==

The Drumright Gasoline Plant No. 2 is listed on the National Register of Historic Places. ==See also==
