When a well strikes a high-pressure formation about 6,500 feet beneath Oklahoma City – and oil erupts skyward – the prolific Oklahoma oilfield will become famous worldwide.

Newsreel photographers will send film of the “Wild Mary Sudik” well to Hollywood. Within a week, newsreels appear in theaters around the country. When the Mary Sudik is brought under control, crews will recover 200,000 barrels of oil from pits and ponds.
The Indian Territory Illuminating Oil Company’s Mary Sudik No. 1 well flows for 11 days before being brought under control on April 6, 1930.
The well, which produces about 20,000 barrels of oil and 200 million cubic feet of natural gas a day, becomes a public sensation known as “Wild Mary Sudik.”
The giant discovery is featured in newsreels and on radio, according to “Oklahoma Journeys,” an audio program of the Oklahoma History Center in Oklahoma City.
“At about 6:30 the morning of March 26, 1930, the crew of roughnecks drilling a well on the property of Vincent Sudik paused in their work,” the program begins about the well, which is near I-240 and Bryant Street in present day Oklahoma City.
“The tired drillers had been waiting for daylight to continue their work,” the audio tape notes.

Experts control the well with “a clever ball-shaped contrivance” that lowers a two-ton “overshot” cap.
The program’s narrator Michael Dean notes that after drilling to drilling to 6,471 feet, the roughnecks overlook a dangerous pressure increase in the well.
“The exhausted crew failed to fill the hole with mud,” he explains. “They didn’t know the Wilcox sand formation was permeated with natural gas under high pressure, and within minutes that sand under so much pressure found a release.”
The drilling crew is caught off guard when oil and natural gas suddenly “came roaring out of the hole,” Dean adds.
“Pipe stems were thrown hundreds of feet into the air like so many tooth picks. First there was gas then the flow turned green gold and then black,” he reports. “Oil shot hundreds of feet into the air, and for the next eleven days, the Mary Sudik ran wild.”
“Wild Mary” Daily Updates
On April 6, Floyd Gibbons of NBC Radio – who broadcast regular reports about the well – reports that after two unsuccessful attempts, the well is closed with a two-ton “overshot” cap.
An Associated Press article describes the “clever equipment” required to control the well without sparking a fire – a “double die was screwed into four inches of casing threads…a clever ball-shaped contrivance, called a fantail, was used to affix the double die to the casing.”
The fantail was placed over the well, “and the ‘Wild Mary’s’ pressure, playing through jets in the contrivance, aided in lowering the cap through the blast,” the article explains.
“With the petroleum geyser halted, operators in the field drew sighs of relief,” it concludes. “A stray spark from two clanking pieces of steel and the territory might have become a raging inferno.”
With the well was brought under control and the danger of fire eliminated, drilling continues at a frantic pace elsewhere in Oklahoma City.
However, the prolific, high-pressure of the Wilcox sands formation continued to challenge drillers and the technologies of the day.
An article in the Southwest Missourian newspaper reported:
Oklahoma City, April 7 – A gas well, estimated to be producing at a rate of 75,000,000 cubic feet a day, blew in at the edge of the city today, creating a new fire threat less than 24 hours after the wild No. 1 Mary Sudik gusher, several miles to the south, had been brought under control.
Recognizing the risks of drilling into the Wilcox sand, Oklahoma City passes additional ordinances for safety and well spacing in the city.
Although the first ram-type blowout preventer had been patented by James Abercrombie in 1926, many high-pressure Texas and Oklahoma oilfields would take time to tame.

The Oklahoma History Center in Oklahoma City includes the Devon Energy Oil and Gas Park.
In December 1933, Abercrombie patented an improved blowout preventer (patent No. 1,834,922), that set a new standard for safe drilling during the Oklahoma City oilfield boom. Read more in “Ending Oil Gushers – BOP.”
Visitors today can see the valve that split in half and view newsreel film of the Wild Mary Sudik in the oil and gas and natural resources on exhibit at the Oklahoma History Center.
There also is the Devon Energy Oil and Gas Park with drilling and production equipment at the center, located on N.E. 23rd Street just east of the state capitol.
