In 1883, tales of a “tar spring” inspired Pennsylvanian Mike Murphy to drill the first Wyoming oil well.

Although not the state’s first oil discovery, the Shannon No. 1 well at Salt Creek, Wyoming, of 1890 will lead to a major find in 1908 – and help launch the petroleum industry in the West.

A few years later, Civil War veteran Philip Martin Shannon will explore more of the Salt Creek oil seeps, revealing a 22,000-acre oil field.

The Salt Creek oil field has produced more than 650 million barrels of oil over the last 100 years – and even more remains in the ground.

In 1837, Washington Irving published The Adventures of Captain Bonneville: or, Scenes beyond the Rocky Mountains of the Far West.

Eastern readers were spellbound by Capt. Benjamin Bonneville’s four-year expedition, encounters with Indians, and detailed accounts of life on the fur-trapping trail.

In the unforgiving lands that would one day become the Wyoming Territory, Bonneville traveled down the Popo Agie River and in 1832 made note of a natural resource that would one day bring a new industry to the state of Wyoming:

“In this neighborhood, the captain made search for ‘the great Tar Spring,’ one of the wonders of the mountains, the medicinal properties of which he had heard extravagantly lauded by the trappers.

After a toilsome search, his expedition found a tar-like substance at the foot of a sand-bluff, a little east of the Wind River Mountains, where it exuded in a black, sticky stream.

“The men immediately hastened to collect a quantity of it, to use as an ointment for the galled backs of their horses, and as a balsam for their own pains and aches,” Bonneville continued.

“From the description given of it, it is evidently the bituminous oil, called petroleum or naphtha, which forms a principal ingredient in the potent medicine called British Oil,” he reported. “In New York, it is called Seneca Oil, from being found near the Seneca lake.”

Exploring Tar Springs and Salt Creek

Fifty years later, tales of the “Great Tar Spring” would lead to Wyoming’s first oil well. In the intervening years, intrepid pioneers first crossed central Wyoming via the rugged “South Pass” route.

These early paths now are national historic trails: the Mormon Pioneer, Oregon, California, and Pony Express – many punctuated with makeshift grave sites of ill-fated travelers.

Salt Creek begins about 20 miles north of Casper, Wyoming. Historians note that Indians knew for many years that oil could be found floating on the surface of the creek at several locations.

America nonetheless continued to grow westward, encouraged by periodic, if transitory, gold rushes. By 1867, the Union Pacific Railroad reached the easternmost boundary of the Wyoming Territory, spawning new towns all along its route.

Because the right of way included substantial land grants on each side of the tracks, railroads were very much in the real estate business and promoted settlement in order to develop their property.

Still, by 1870 the pioneer population of Wyoming was just over 9,000 in a territory of 97,809 square miles.

The government owned almost half of the territory and encouraged development of mineral resources in these public lands through the federal Placer Act.

In the East, declining production from Pennsylvania oil fields in the 1880s prompted the young petroleum industry to look westward.

Pennsylvanians drill First Wyoming Oil Well

Mike Murphy was a Pennsylvania-born Irishman who had come to the Nebraska Territory in 1854 as a land surveyor. He served in the territorial legislature until being lured to Colorado in search of gold in 1859. Murphy later went to Montana for gold and in 1876, he was off to the Black Hills, still prospecting.

When he returned to Wyoming in 1883, Murphy and his brother, Frank, bought an oil lease from Dr. George B. Graff – on the very site of Capt. Bonneville’s “great tar spring.”

The Murphy brothers found oil at 300 feet in what would become known as the Chugwater formation. The news spread quickly and inspired others to stake their own “placer” mineral claims on promising sites. One of these sites was the Salt Creek valley area north of old Ft. Caspar, which would one day yield millions of barrels of oil.

Placer claims on government lands could be filed in 20-acre blocks by an individual or 160 acres by an “association” of eight individuals.

For the claimant to be granted a legitimate patent on the land, the law required drilling  a well, at least $500 in improvements, “oil in commercial quantity” (often disputed) and a $2.50 per acre fee.

Complicating the process was the government’s inclination to withdraw lands from the public domain. Competing legitimacy disputes, claim jumping, litigation, and even gun play were the natural byproducts of placer claims.

More Black Gold Discoveries

In 1887, perhaps lured by tales of Mike Murphy’s oil discovery, a tenacious but unsuccessful gold prospector by the name of Cy Iba returned from California with his four sons, two daughters, and their families.

He began staking his own and “association” placer claims in Salt Creek. Iba and his family dug and timbered and staked and re-staked, eventually accumulating 30 claims in anticipation of one day selling valuable oil leases.

Meanwhile, Wyoming continued to grow with the railroads. The Fremont, Elkhorn & Missouri Valley Railroad pushed westward and delivered its first passengers to what would become Casper, Wyoming, in June 1888. Two years later, Iba came into conflict with a group of New York investors headed by H.D. Schoonmaker.

This group, “The Central Association of Wyoming,” had acquired its own placer claims. Iba sued and after several years of litigation, he settled for an 80-acre tract of the disputed “Jackass Claim.” Years later, the “Iba 80″ would become one of the Salt Creek oil field’s best producers.

Philip M. Shannon brought valuable experience (and equipment) from Pennsylvania’s oil fields.

First True Wyoming Oilman

Noted Wyoming historian Mike Mackey says Philip Martin Shannon was Wyoming’s first “legitimate” oilman since, “he plans on coming to Wyoming, drilling wells, refining the product, and finding a market for it.”

Shannon was a Civil War veteran and successful Pennsylvania oil businessman who first visited the area in 1884, Mackey writes in – Black Gold, Patterns in the Development of Wyoming’s Oil Industry.

Shannon chose to drill for oil on the northeast side of the Salt Creek activity, and with a small group of investors, began shipping equipment from Pennsylvania to the new Casper railroad station, still a 50 mile wagon haul from the proposed site.

In August 1890, just one month after Wyoming became the 44th state, Shannon brought in his first well. Even unrefined, the new state’s oil proved to be an excellent lubricant. The producing zone will become known as the Shannon sandstone.

The Wyoming Derrick, Casper’s newspaper, enthusiastically announced, “Wyoming will become the greatest and wealthiest mineral producing state in the Union.”

The “Big Dutch” No. 1 well of 1908 initially produced 600 barrels of oil a day from 1,050 feet. Some Salt Creek wells produced from as shallow as 22 feet!

Within 20 months, Shannon and his associates had two producing wells, one dry hole, and a fourth well underway. Their only market for this unrefined lubricating oil was the railroads. Shannon negotiated agreements with the Fremont, Elkhorn & Missouri Valley Railroad as well as the Cheyenne & Northern.

Still, his oil had to be laboriously hauled in barrels by wagon to the railhead in Casper. The first delivery of 45 barrels took five days using a string team of 14 horses and three tandem wagons. In the distant East, a pessimistic Harper’s Magazine reported, “…it is noticeable now that this oil excites little human interest, and interests still less capital.”

Salt Creek saw its first full scale water-flood development in 1962. In 2003, the field successfully completed a pilot carbon dioxide injection program.

Casper Refinery

To expand their markets, Shannon and his Pennsylvania investors began building a refinery in Casper in 1894. Wyoming’s population had grown to over 62,000.

Within a year, the new refinery was able to produce 100 barrels a day of 15 different grades of lubricant, from “light cylinder oil” to heavy grease.

Soon thereafter, Shannon and his associates incorporated as the Pennsylvania Oil and Gas Company with 6,000 shares of stock.

The company’s assets included the Casper refinery and placer claims on over 3,000 acres of the north perimeter of Salt Creek. By 1904, the Pennsylvania Oil and Gas Company owned 14 small wells, each producing ten to 40 barrels per day – more than the Casper refinery or the market could accommodate.

The Salt Creek-Midwest, Wyoming, boom began in 1908. New laws in the 1930s allowed companies to pool their interests and hire a single company to operate – drill, pump, and maintain – oil production.

Despite a growing population (1900 census counted 92,531) and improved railroad access, transportation costs meant that Wyoming oil could not successfully compete for the distant eastern markets. The Pennsylvania Oil and Gas Company struggled. By October 1904, the company was sold to French and Belgian investors – who  fared no better. The Casper refinery was closed.

Placer Claims

Wyoming’s first real petroleum boom began in 1908 when the Dutch-owned Petroleum Maatschappij Salt Creek Company completed the “Big Dutch” well about 40 miles north of Casper.

Phillip Shannon’s venture illustrates the challenges faced by early oilmen in the development of Wyoming’s oil industry. The legitimacy problems of placer claims remained problematical for many years to come.

By 1912, every individual or company in the Salt Creek oil field was either suing or being sued. Isolation from the petroleum-hungry eastern markets also endangered every oil venture.

Even with the advent of railroad tank cars, Wyoming oil could not compete in eastern markets because of transportation costs. These early problems eventually yielded to the tenacity of the stubborn oilmen who confronted them. In 1920, the “Oil and Gas Leasing Act” finally provided relief from the legal wrangling over placer claims.

In Midwest, “the heart of central Wyoming, you will discover its history has a taste of the oil field pioneers and new oil field related industries.”

First Major Wyoming Oil Boom

Wyoming’s first real oil boom would have to wait until the Dutch-owned Petroleum Maatschappij Salt Creek Company’s well erupted on October 23, 1908, bringing a new flood of entrepreneurs and investors.

Although Salt Creek was known to be productive, the central Salt Creek dome received little attention until noted Italian geologist Dr. Cesare Porro recommended the drilling site to Petroleum Maaschappij in 1906.

Drillers J. E. Stock and his father, working for an English corporation known as the Oil Wells Drilling Syndicate, completed the well at 1,050 feet with initial production of 600 barrels a day.

“Initial development of Salt Creek Oil field commenced in 1889 with the majority  of primary development occurring between 1915 and 1930,” notes the U.S. Department of the Interior. “Early  records indicate that oil was  found at depths as shallow as 22 feet in 1911.”

By 1930, about one-fifth of all oil produced in the United States came from Salt Creek. More than 4,000 petroleum wells have since been drilled in the ten producing zones of the 22,000-acre field. In 2007 alone, Salt Creek produced almost three million barrels of oil.

An article posted by historian Tom Rea adds another aspect to the field’s story:

November 19, 1925 was a cold night for football in the oil boomtown of Midwest, Wyoming. “Don’t Miss It,” the Casper Herald had advised the day before. “Something New, Football at Night, Casper vs. Midwest.”

“Floodlights,” the advertisement continued, would be “assisted by open gas flares for light and warmth—the roads are fine…” Fine perhaps, but still dirt in 1925. Midwest is 40 miles north of Casper.

For the football game, Midwest Refinery Company electricians set up twelve floodlights of 1,000 candlepower each around the field, four more of 2,000 candlepower, and from the top of an oil derrick near the field, a huge searchlight swung its beam over the players and the crowd.

Electricity had come to the oil fields around Midwest earlier that year, when the company built an electric plant to power thousands of oil-well pumps.

Born in 1915, Wyoming author and historian Pauline L. Schultz founded the Salt Creek Oil Field Museum in 1980. She received a National Humanities Medal from President George W. Bush in 2007.

Rea also notes in Boom, Bust, and After – Life in the Salt Creek Oil Field that new laws in the 1930s allowed companies to pool their interests and hire a single company to operate – drill, pump, and maintain – oil fields.

Salt Creek Museum

Today, the Salt Creek oil field has produced more than 650 million barrels of oil over the last 100 years – and even more remains in the ground. Using advanced technologies, companies inject carbon dioxide into wells and the added pressure keeps oil flowing.

The Salt Creek Museum in Midwest displays artifacts and more than 4,000 photographs of the Salt Creek and Teapot Dome Naval Reserve No. 3 oilfields, illustrating the area’s history from 1889 to today, according to Curator Pauline Schultz. The museum holds a full set of Midwest Refining Company Books from 1920-1930.

Frederick Cook explored for oil in Wyoming ion 1917.

The Salt Creek field, about 40 miles north of Casper, was once among the largest light crude oil fields in the world. It became famous for its gushers and a pipeline to a Casper refinery was built in 1911.

Salt Creek was surpassed in the 1920s by the nearby Teapot Dome, the source of financial scandal during the Warren G. Harding administration.

Explorer Fails as Oilman

In 1917 the discredited Arctic expedition leader Dr. Frederick Albert Cook  conducted geological explorations in Wyoming for his newly formed company, the Texas Eagle Oil Company of Fort Worth.

Soon, the once famous controversial explorer’s fraudulent claims lead to several failed oil company ventures, a mail fraud conviction and jail time.
