Determination and deeper wells launched state’s petroleum industry in 1948.

After decades of expensive failed exploration attempts (a few small producers but mostly dry holes), the first significant Utah oil well was competed on September 18, 1948, in the Uinta Basin. The Ashley Valley No. 1 well, about 10 miles southeast of Vernal, produced about 300 barrels a day from a depth of 4,152 feet.

“The honor of bringing in the state’s first commercial oil well went not to the ‘Majors’ but to an ‘Independent’ — the Equity Oil Company,” noted a Utah historian in 1962.

“It is interesting to note that J.L. (Mike) Dougan, president and general manager of Equity Oil Company and a Salt Lake City resident, had been drilling for oil in Utah for over 25 years,” explained Osmond Harline in his article, “Utah’s Black Gold: The Petroleum Industry,” in the Utah Historical Quarterly (Vol. 31. No. 3). 

Dougan beat out larger and better financed competitors, including Standard Oil of California, Pure Oil, Continental Oil, and Union Oil. Unlike the earlier attempts, Dougan had drilled far beyond the basin’s typical depth of 1,000 feet to 2,000 feet. His Utah discovery quickly launched a deep-drilling boom. 

Within three months, eight more wells were drilled and development of the field followed. Production soon averaged just under one million barrels a year from about 30 wells as exploration companies began drilling 5,000 feet to 8,000 feet and even deeper into the Uinta Basin.


Early Oil Finds

Long before the first Utah oil well, signs of petroleum (natural oil seeps) had been noted by geologists near Rozel Point on the northern shore of Great Salt Lake as early as the mid-1850s.

Some oil was found in Utah’s Uinta Basin as early as1908.

“The exploratory period began in 1850 when Captain Howard Stansbury, while on a survey of the Great Salt Lake for the Army Corps of topographical engineers, discovered evidence of ‘petroliem’ along the northern shore of the lake,” explained Utah historian Walter Jones. The search would continue for decades.

In 1891, the Utah Oil Company, whose board included future Governor Simon Bamberger, drilled an unsuccessful 1,000-foot-deep well near Green River. Dozens of “dry holes” were drilled throughout the state by the 1900.

Finally, in March 1908, a former gold prospector named E.L. Goodridge completed an oil well in San Juan County, “and by the end of 1909 approximately seven oil companies had started work on no less than twenty-five wells near Mexican Hat,” Jones noted.

The Mexican Hat oilfield never became a major oil producer, but it and another discovered nearby produced enough oil to supply small local refineries that operated intermittently for years.

Jones added in his 1990 article, The Growth of Utah’s Petroleum Industry, that in the 1920s enterprising petroleum operators began testing offshore drilling technologies at the Great Salt Lake. The Lakeside Oil Company drilled on the western shore of the lake — and an offshore rig was built on a pier near Rozel Point at the lake’s northern tip. 

However, the state’s petroleum industry was still decades away from its true beginning.

Deadly Oil Search

Long before the state’s first commercial well was completed, residents of St. George had hoped the “shooting” of Arrowhead Petroleum Company’s Escalante No. 1 wildcat well on March 6, 1935, would bring prosperity to their small town a few miles north.

Unaware of impending danger, between 70 and 100 people gathered to watch as workers prepared to fracture a sand formation 3,200 feet deep. An explosion occurred at about 9:40 pm while six 10-foot-long torpedoes, “each loaded with nitroglycerin and TNT and hanging from the derrick, were being lowered into the well,” noted the Washington County Historical Society.

Ten people lost their lives and dozens were injured by the explosion, which “sent a shaft of fire into the night that was seen as far as 18 miles away.” Memorial services for the victims were held in the St. George Tabernacle on March 8, 1935.

The accident, still Utah’s worst petroleum-related disaster, was in investigated in The Escalante Well Incident by Clark N. Nelson Sr., who in 2007 wrote wrote a personal perspective of the tragedy, “based upon historical accounts, photograph comparisons, abstract conclusions and assumptions, following a search for the former site.”

Mike Dougan’s 1948 Discovery

“Toward the end of World War II oilmen began to accelerate Utah’s petroleum operations once again,” Jones explained. “From 1945 through 1947 they succeeded in finishing the groundwork necessary to propel the state into a period of commercial oil production.”

The focal point of drilling became the Uinta Basin, where a number of large companies searched. “From the late 1940s until 1957 almost all of Utah’s oil development occurred along the eastern border of the state from the Uinta Basin to the San Juan River,” reported Jones.

However, major oil companies like Standard Oil of California and Gulf continued to drill only expensive dry holes. The basin’s first commercial oil discovery came in September 1948 — a well drilled by Mike Dougan’s small, independent exploration company. “Shortly thereafter, Utah was one of the top 15 oil producing states — a position it has held since,” Jones concluded.

By the early 2000s, the Uinta Basin’s coalbed methane in Utah and Colorado were becoming one of the major gas-producing regions in the United States. The international energy service company Halliburton has noted this about the basin:

Located on a remote desert plateau in Utah and Colorado, and is considered one of the major coalbed methane producing areas in the United States, Uinta is estimated to have between eight and 10 trillion cubic feet of gas reserves. Coal depths in this basin vary from 1,000 feet to 7,000 feet over a 14,450 square mile region.

Utah produced more than 8.1 trillion cubic feet of natural gas valued at more than $1.7 billion in 2010,  according to the Utah Department of Natural Resources

With about12,300 active wells in 2014, Utah ranked 11th in the country in  oil production during and 10th in natural gas production (not including federal offshore production areas.

Utah also was home to one of the earliest petroleum companies to ever attempt extracting oil from dense oil shale deposits -0 in the  (learn more in Ute Oil Company — Oil Shale Pioneer).
