In this flammable workplace, danger can come from anywhere, including the sky.
Whether ignited by accident, natural phenomena, or acts of war, oilfield fires have challenged America’s petroleum industry since the earliest wells. Catastrophic fires have threatened the search for oil and natural gas since the first U.S. oil well, completed on August 27, 1859, along a Pennsylvania creek.
Just six weeks after his discovery, Edwin L. Drake’s well caught fire when driller William “Uncle Billy” Smith inspected the well with an open lamp, igniting seeping natural gas. Flames consumed the cable-tool derrick, engine-pump house, stored oil, and Smith’s nearby shack.
Drake Well Museum exhibits in Titusville, Pennsylvania, include a replica of the cable-tool derrick and engine house that drilled the first U.S. well in 1859.
Today, visitors to the Drake Well Museum at Titusville tour the latest reconstructed cable-tool derrick and its engine house along Oil Creek where the former railroad conductor found oil at a depth of 69.5 feet. He revealed a geologic formation later called the Venango sandstone.
Another Drake Well Museum exhibit preserves the Titusville Fire Department’s coal-fired steam pumper (see Oilfield Photographer John Mather). As the new U.S. petroleum industry learned from hard experience, firefighting technologies evolved in northwestern Pennsylvania’s “Valley that Changed the World.”
Early Firefighting Lessons
In 1861, an explosion and fire at Henry Rouse’s gushing oil well made national news when he was killed along with 18 workers and onlookers (see Rouseville 1861 Oil Well Fire). In 1977, the Smithsonian American Art Museum acquired landscape artist James Hamilton’s “Burning Oil Well at Night, near Rouseville, Pennsylvania,” painted soon after the fire.
The dangerous operating environment of a cable-tool rig included a spinning bull wheel, a rising and falling heavy wooden beam, a steam boiler, and crowded spaces.
The pounding iron drill bit frequently needed to be withdrawn and hammered sharp using a small, but red-hot forge — often set up just feet from the wellbore.
Lighting striking derricks and oilfield tank farms also would prove challenging.

Late 19th century oilfield fire prevention remained rudimentary as exploration moved westward. Safety lamps like one with two spouts popularly known as the “Yellow Dog” lantern, were not particularly safe. The rapidly growing petroleum industry needed new technologies for preventing fires or putting them out.
As drilling experience grew, refineries responded to skyrocketing public demand for the lamp fuel kerosene. Production from new oilfields in Texas, Kansas, and Oklahoma led to construction of safer storage facilities, but advances in drilling deeper wells brought fresh challenges (see Ending Oil Gushers – BOP).
Firefighting with Cannons
Especially in early oilfields, working in such a flammable workplace could bring danger from everywhere — including the sky. Lightning strikes to wooden storage tanks created flaming cauldrons.

In the rush to exploit early oilfields, wooden derricks often crowded an oil-soaked landscape, leaving workers — and nearby towns — dangerously exposed to an accidental conflagration. Many oil patch community oil museums have retained examples of early smooth-bore cannon used to fight fires.
A civil-war era field cannon exhibit in Corsicana, Texas, tells the story of a cannon from the Magnolia Petroleum Company tank farm. “It was used to shoot a hole in the bottom of the cypress tanks if lightning struck,” a plaque notes. “The oil would drain into a pit around the tanks and be pumped away.”

Oilfield firefighting using cannons has continued into the 21st century. In May 2020, a well operated by the Irkutsk Oil Company in Russia’s Siberian region ignited a geyser of flaming oil and natural gas. When efforts to control the blowout failed, the Russian Defense Ministry flew in a 1970s era anti-tank gun and its Hungarian crew.
From about 200 yards away, the Hungarian artillerymen (Covid-19 masked) repeatedly fired their 100-millimeter, smooth-bore Rapira MT-12 gun at blazing oilfield equipment, “breaking it from the well and allowing crews to seal the well,” according to the Russian Defense Ministry.
In addition to using cannons to fire well fires, other techniques have included smothering them using cranes to lower iron metal caps (see Kansas Gas Well Fire) or detonating an explosive from above to rob the flames of air. Using a wind machine must count among the more unusual methods.
Firefighting with Wind
In 1929, about 400 volunteers took on a raging oilfield fire that had destroyed seven derricks and two oil well “heavy producers” at Santa Fe Springs, California. “Roaring Flames Turn Black Gold To Smoke,” proclaimed a Los Angeles Times headline on June 12.
The Santa Fe Springs Hathaway Ranch and Oil Museum, “a museum of five generations of Hathaway family and Southern California history,” has preserved rare motion picture clips of a propeller-driven “Wind-making Machine” in action — although the wind proved no match for the flames.
“The machine that made the wind that conquered a fire in a Santa Fe Springs oilfield on June 15, 1929,” used a three-bladed airplane propeller and a powerful motor to blow heat away from the men at work fighting the fire. “A track of boards was built for the machine over a lake of oil, mud and water in the ‘hot zone’ of the big fire.” — Hathaway Ranch and Oil Museum, Santa Fe Springs, California.
The fire depicted in the silent film is intense, “so firefighting equipment is appropriately distant from the well head, including the wind machine,” explained museum Curator of Media Archives Terry Hathaway.
“It looks like its use is more or less limited to blowing hot air, smoke and steam (from firefighting water hoses) away from the workers and toward the fire,” he added.
Hathaway explained that the wind machine on the back of a truck probably had no direct influence on the fire itself, due to distance and the ferocity of the high-pressure well blowout, “but it apparently may have made things more tenable for the firefighters by keeping them relatively cool and smoke free.”
A modern version of the 1929 wind-making machine returned in 1991, after Saddam Hussein’s retreating Iraqi army set hundreds of wells ablaze in Kuwait oilfields. Firefighting technologies by then had evolved into using jet engines. MB Drilling Company of Szolnok, Hungary, sent a three-man team with “Big Wind,” a modern version of the 1929 wind-making machine.
Instead of a piston-driven propeller on a vintage truck bed, twin MIG-21 turbojets were mounted in place of the turret on a World War II era Soviet T-34 tank. The jet engines generated 700 mph of thrust, which blasted hundreds of gallons of water per second into the flames.
Image from Romanian video of 1991 Kuwaiti oilfields: “Twin MIG-21 turbojets mounted on a World War II era Soviet T-34 tank dubbed “Big Wind” generated 700 mph thrust blasting hundreds of gallons of water per second into the fire.”
The Hungarian team members put out their assigned fires and recapped nine wells in 43 days, according to a 2001 Car and Driver article, “Stilling the Fires of War.”
Firefighting with Explosives
Many firefighting teams went to Kuwait following the Persian Gulf War, including Paul “Red” Adair, whose dramatic oilfield feats had been popularized in the 1968 movie “Hellfighters.” Adair and his team extinguished 117 Kuwaiti oil well fires by robbing the flames of oxygen using explosives.
As the Hungarian crew chief of “Big Wind” observed at the time, “Would you really want to walk up to a 2,000-degree flame through burning heat and oil rain carrying explosives?”
A century earlier, Karl T. Kinley did just that. Kinley, a California oil well “shooter” (see Shooters — A History of Fracking) during the early 1900s, learned from first-hand experience that a dynamite explosion could “blow out” a wellhead fire. Kinley’s son Myron Macy Kinley established the pioneering oilfield service business M.M. Kinley Company after learning from his father’s highly dangerous experiments.
Readers Digest in 1953 declared Myron M. Kinley “the unrivaled world-champion fighter of oil fires.” A TIME article described him as “the indispensable man of the oil industry.”
But with chance of terrible injuries or death ever present, firefighting success was not without cost. Kinley’s brother Floyd was killed by falling rig debris in 1938 as they fought a runaway well fire near Goliad, Texas.

Myron Kinley has been called the grandfather of modern oil well fire fighting, according to the Oklahoma Historical Society. Photo by A.Y. Owen courtesy OHS Oklahoma Publishing Company Photography Collection.
Kinley, a mentor of “Red” Adair, developed technologies at M.M. Kinley Company that inspired other firefighting experts, including Joe R. Bowden Sr., who founded Wild Well Control in 1975 to provide emergency response, safety training, and relief well engineering, and Bobby Joe Cudd, who established Woodward, Oklahoma-based Cudd Well Control Company in 1977 with eight employees and a “hydraulic snubbing unit.”
After they had worked for the Red Adair Service and Marine Company, Asger “Boots” Hansen and “Coots” Mathews in 1978 opened an office in Houston for what could become Boots & Coots International Well Control (today a Halliburton Company).
Adair had joined Myron Kinley’s California oilfield service company after serving with a U.S. Army bomb disposal unit during World War II. After starting his own company by 1959, “Red” improved firefighting technologies, developing new tools, equipment, and techniques for “wild well” control.
Adair was 75 years old when he successfully tamed roaring fires in Kuwait’s scorched oilfields. As early as 1962, his Red Adair Company had “put out a Libyan oil well fire that had burned so brightly that astronaut John Glenn could see it from space,” the Los Angeles Times reported.
Firefighting with Nukes
Between 1966 and 1981, the Union of Soviet Socialist Republics snuffed out runaway fires at natural gas wells using subsurface nuclear detonations. The experiments, part of the broader “Program No. 7 – Nuclear Explosions for the National Economy,” imitated a U.S. initiative, “Plowshare,” seeking peaceful uses of nuclear bombs.
According to the Lawrence Livermore National Laboratory, USSR scientists code-named five secret attempts Urta-Bulak, Pamuk, Crater, Fakel, and Pyrite.
The first experimental detonation, Urta-Bulak in 1966, came after three-years and failed conventional attempts to extinguish a blazing natural gas well in Southern Uzbekistan. Scientists positioned a special 30-kiloton package within 300 feet of the borehole by slant drilling.
Detonated in clay strata at a depth of 4,921 feet, the nuclear explosion’s shock wave sealed the well within 23 seconds, staunching the daily waste of 423 million cubic feet of natural gas, reported Russian television.

In 1968, the Pamuk well explosion used a larger, 47-kiloton nuclear device that measured 9.5 inches by 10 feet. Two years of uncontrolled natural gas and saturated surrounding landscape yielded to the nuclear detonation at a depth of 8,000 feet. The runaway gas well died out seven days later.
Twice in 1972, USSR scientists used lower-yield detonations to extinguish massive fires. The smallest of the nuclear firefighting devices (3.8 kiloton) on July 7 squelched a runaway gas well fire in the Ukraine, about 12 miles north of Krasnograd.
The USSR program’s only recorded failure came in 1981 with the last Soviet use of firefighting nukes. On May 5, a nuclear device failed to shut down a 56 million cubic feet per day out of control natural gas well. The code-named Pyrite device had been positioned proximate to the well at a depth of 4,957 feet.
The 37.6-kiloton detonation in a sandstone-clay formation failed to seal the gas well, according to the USSR Ministry of Defense, which provided little more information.
By the 1950s, America was considering how to use nuclear weapons for constructive purposes — “Atoms for Peace.” In December 1961, Project Plowshare began examining the feasibility of various projects, including ways to improve natural gas production (see Project Gasbuggy tests Nuclear “Fracking”).
Neither the Project Plowshare nor the Soviet Union’s Program No. 7 produced desirable results. With or without nukes, oilfield work then and now remains among the most dangerous jobs in the world. Fortunately, safety and prevention methods have improved along with the technologies for “making hole” and producing oil since the industry’s earliest wells in northwestern Pennsylvania.

As the U.S. petroleum industry expanded following the January 1901 “Lucas Gusher” at Spindletop Hill in Texas, service company pioneers like Carl Baker and Howard Hughes brought new technologies to oilfields.
Baker Oil Tools and Hughes Tools specialized in maximizing petroleum production, as did oilfield service company competitors Schlumberger, a French company founded in 1926, and Halliburton, which began in 1919 as a well-cementing company.
R.C. “Carl” Baker Sr.
Baker Oil Tool Company (later Baker International) had been founded by Reuben Carlton “Carl” Baker Sr., who among other inventions patented a cable-tool drill bit in 1903 after founding the Coalinga Oil Company in Coalinga, California.
Oil wells Carl Baker had drilled near Coalinga encountered hard rock formations that caused problems with casing, so he developed an offset cable-tool bit allowing him to drill a hole larger than the casing. He also patented a “Gas Trap for Oil Wells” in 1908, a “Pump-Plunger” in 1914, and a “Shoe Guide for Well Casings” in 1920.
Baker Tools founder R.C. “Carl” Baker in 1919.
Coalinga was “every inch a boom town and Mr. Baker would become a major player in the town’s growth,” according to the now closed R.C. Baker Memorial Museum. He also organized several small oil companies and the local power company, and established a bank.
After drilling wells in the Kern River oilfield, Baker added to his technological innovations on July 16, 1907, when he was awarded a patent for his Well Casing Shoe (No. 860,115), a device ensuring uninterrupted flow of oil through a well. His invention revolutionized oilfield production.

In 1913, Baker organized the Baker Casing Shoe Company (renamed Baker Tools two years later). He opened his first manufacturing plant in Coalinga.
When Baker Tools headquarters moved to Los Angeles in the 1930s, the building remained a company machine shop. It was donated by Baker to Coalinga in 1959. Two years later, the original machine shop and office of Baker Casing Shoe reopened as the R.C. Baker Memorial Museum.
By the time Carl Baker Sr. died in 1957 at age 85, he had been awarded more than 150 U.S. patents in his lifetime. “Though Mr. Baker never advanced beyond the third grade, he possessed an incredible understanding of mechanical and hydraulic systems,” reported the former Coalinga museum.
Baker Tools became Baker International in 1976 and Baker Hughes after the 1987 merger with Hughes Tool Company.

Howard R. Hughes Sr.
The Hughes Tool Company began in 1908 as the Sharp-Hughes Tool Company founded by Walter B. Sharp and Howard R. Hughes, Sr.
“Fishtail” rotary drill bits became obsolete in 1909 when the two inventors introduced a dual-cone roller bit. They created a bit “designed to enable rotary drilling in harder, deeper formations than was possible with earlier fishtail bits,” according to a Hughes historian. Secret tests took place on a drilling rig at Goose Creek, south of Houston.
“In the early morning hours of June 1, 1909, Howard Hughes Sr. packed a secret invention into the trunk of his car and drove off into the Texas plains,” noted Gwen Wright of History Detectives in 2006. The drilling site was near Galveston Bay. Rotary drilling “fishtail ” bits of the time were “nearly worthless when they hit hard rock.”
The new technology would soon bring faster and deeper drilling worldwide, helping to find previously unreachable oil and natural gas reserves. The dual-cone bit also created many Texas millionaires, explained Don Clutterbuck, one of the PBS show’s sources.
“When the Hughes twin-cones hit hard rock, they kept turning, their dozens of sharp teeth (166 on each cone) grinding through the hard stone,” he added.
Although several inventors tried to develop better rotary drill bit technologies, Sharp-Hughes Tool Company was the first to bring it to American oilfields. Drilling times fell dramatically, saving petroleum companies huge amounts of money.
Howard Hughes Sr. of Houston, Texas, received a 1901 patent for a dual-cone drill bit.
The Society of Petroleum Engineers has noted that about the same time Hughes developed his bit, Granville A. Humason of Shreveport, Louisiana, patented the first cross-roller rock bit, the forerunner of the Reed cross-roller bit.
Biographers have noted that Hughes met Granville Humason in a Shreveport bar, where Humason sold his roller bit rights to Hughes for $150. The University of Texas Center for American History collection includes a 1951 recording of Humason’s recollections of that chance meeting. He recalled spending $50 of his sale proceeds at the bar during the balance of the evening.
After Sharp died in 1912, his widow Estelle Sharp sold her 50 percent share in the company to Hughes. It became Hughes Tool in 1915. Despite legal action between Hughes Tool and the Reed Roller Bit Company that occurred in the late 1920s, Hughes prevailed – and his oilfield service company prospered.
By 1934, Hughes Tool engineers design and patented the three-cone roller bit, an enduring design that remains much the same today. Hughes’ exclusive patent lasted until 1951, which allowed his Texas company to grow worldwide. More innovations (and mergers) would follow.

Frank Christensen and George Christensen had developed the earliest diamond bit in 1941 and introduced diamond bits to oilfields in 1946, beginning with the Rangley field of Colorado. The long-lasting tungsten carbide tooth came into use in the early 1950s.
After Baker International acquired Hughes Tool Company in 1987, Baker Hughes acquired the Eastman Christensen Company three years later. Eastman was a world leader in directional drilling.
When Howard Hughes Sr. died in 1924, he left three-quarters of his company to Howard Hughes Jr., then a student at Rice University. The younger Hughes added to the success of Hughes Tool while becoming one of the richest men in the world. His many legacies include founding Hughes Aircraft Company and the Howard Hughes Medical Institute.

Oilfield Service Competition
A major competitor for any energy service company, today’s Schlumberger Limited can trace its roots to Caen, France. In 1912, brothers Conrad and Marcel began making geophysical measurements that recorded a map of equipotential curves (similar to contour lines on a map). Using very basic equipment, their field experiments led to invention of a downhole electronic “logging tool” in 1927.
After developing an electrical four-probe surface approach for mineral exploration, the brothers lowered another electric tool into a well. They recorded a single lateral-resistivity curve at fixed points in the well’s borehole and graphically plotted the results against depth – creating first electric well log of geologic formations.
Meanwhile another service company in Oklahoma, the Reda Pump Company had been founded by Armais Arutunoff, a close friend of Frank Phillips. By 1938, an estimated two percent of all the oil produced in the United States with artificial lift, was lifted by an Arutunoff pump.

Densmore brothers advanced oil industry infrastructure — and helped create “QWERTY” typewriter keyboard.
As Northwestern Pennsylvania oil production skyrocketed following the Civil War, railroad oil tank cars fabricated by two brothers improved shipment volumes from oilfields to kerosene refineries. The tank car designed by James and Amos Densmore would not last, but more success followed when Amos invented a new keyboard arrangement for typewriters.
Flatbed railroad cars with two wooden oil tank cars became the latest advancement in oilfield infrastructure after the Densmore brothers patented their design on April 10, 1866.
The inventors from Meadville, Pennsylvania, had developed an “Improved Car for Transporting Petroleum” one year earlier in America’s booming oil regions. The first U.S. oil well had been drilled just seven years earlier along Oil Creek in Titusville.
The first functional railway oil tank car was invented and constructed in 1865 by James and Amos Densmore at the Miller Farm along Oil Creek, Titusville, Pennsylvania. Photo courtesy Drake Well Museum and Park.
Using an Atlantic & Great Western Railroad flatcar, the brothers secured two tanks in order to ship oil in bulk. The patent (no. 53,794) described and illustrated the railroad car’s design.
The nature of our invention consists in combining two large, light tanks of iron or wood or other material with the platform of a common railway flat freight-car, making them practically part of the car, so as they carry the desired substance in bulk instead of in barrels, casks, or other vessels or packages, as is now universally done on railway cars.
Development of railroad tank cars came when traditional designs, including the flatcar, hopper, and boxcar, proved inadequate for large amounts of oil — often shipped in 42-gallon barrels.
New designs were born out of necessity, as the fledgling oil industry demanded a better car for the movement of its product, according to American-Rails.com.
“Before the car was developed, railroads used a combination of boxcars, flatcars, and gondolas to haul everything from lumber and coal to crude oil, molasses, and water (by use of barrels),” noted Adam Burns in 2022. “One of the most prolific car types you will find moving within a freight train today is the tank car.”
Prone to leaks and top heavy, Densmore tank cars provided a vital service, if only for a few years before single, horizontal tanks replaced them.
According to transportation historian John White Jr., the Densmore brothers’ oil tank design essentially consisted of a flat car with wooden vats attached. “The Central Pacific is known to have used such specialized cars to transport water, he noted in his 1995 book, The American Railroad Freight Car.
“However, prior to the discovery of oil by Colonel Edward (sic) Drake near Titusville, Pennsylvania, on August 27, 1859, the tank car was virtually non-existent,” added White, a former curator of Transportation at the Smithsonian Institution.
Dual Tank Design
The brothers further described the use of special bolts at the top and bottom of their tanks to act as braces and “to prevent any shock or jar to the tank from the swaying of the car while in motion.”
A Pennsylvania Historical Commission marker on U.S. 8 south of Titusville commemorates the Densmore brothers’ significant contribution to petroleum transportation technology. Dedicated in 2004, the marker notes:
The first functional railway oil tank car was invented and constructed in 1865 by James and Amos Densmore at nearby Miller Farm along Oil Creek. It consisted of two wooden tanks placed on a flat railway car; each tank held 40-45 barrels of oil. A successful test shipment was sent in September 1865 to New York City. By 1866, hundreds of tank cars were in use. The Densmore Tank Car revolutionized the bulk transportation of crude oil to market.
The benefit of such railroad cars to the early petroleum industry’s infrastructure was immense, especially as more Americans eagerly sought oil-refined kerosene for lamps.
Despite design limitations that would prove difficult to overcome, independent producers took advantage of the opportunity to transport large amounts of petroleum. Other transportation methods required teamsters hauling barrels to barges on Oil Creek and the Allegheny River to get to kerosene refineries in Pittsburgh.

As larger refineries were constructed, it was found that it cost $170 less to ship 80 barrels of oil from Titusville to New York in a tank car instead of individual barrels. But the Densmore cars had flaws, notes the Pennsylvania Historical Commission.
They were unstable, top heavy, prone to leaks, and limited in capacity by the eight-foot width of the flatcar. Within a year, oil haulers shifted from the Densmore vertical vats to larger, horizontal riveted iron cylindrical tanks, which also demonstrated greater structural integrity during derailments or collisions.
The same basic cylindrical design for transporting petroleum can be seen as modern railroads load products from corn syrup to chemicals — all in a versatile tank car that got its start in the Pennsylvania oil industry.
The largest tank car ever placed into regular service was Union Tank Car Company’s UTLX 83699, rated at 50,000 gallons in 1963 and used for more than 20 years. A 1965 experimental car built by General American Transportation, the 60,000-gallon “Whale Belly,” GATX 96500, is now on display at the National Museum of Transportation in Saint Louis.
Oil Tanks to Typewriters
Although the Densmore brothers left the oil region by 1867 — their inventiveness was far from over. In 1875, Amos Densmore assisted Christopher Sholes to rearrange the “type writing machine” keyboard so that commonly used letters no longer collided and got stuck. The “QWERTY” arrangement vastly improved Shole’s original 1868 invention.
Amos Densmore helped invent one of the first practical typewriters.
Following his brother’s work with Sholes, inventor of the first practical typewriter, James Densmore’s oilfield financial success helped the brothers establish the Densmore Typewriter Company, which produced its first model in 1891. Few historians have made the oil patch to typewriter keyboard connection — including Densmore biographers.
The Pennsylvania Historical Commission reported that biographies of the Densmore brothers — and their personal papers at the Milwaukee Public Museum — all refer to their innovative typewriters, “but make no mention of their pioneering accomplishment in railroad tank car design.”
