Giant oilfield discovery in 1928 at Hobbs launched the New Mexico petroleum industry.
“It was desolate country – sand, mesquite, bear grass and jack rabbits. Hobbs was a store, a small school, a windmill, and a couple of trees.” — New Mexico roughneck.
Although the Hobbs discovery came six years after the first oil production (seven years after the first natural gas well), petroleum geologists soon called it the most important single oil find in New Mexico history.
The Midwest State No. 1 well — spudded in late 1927 using a standard cable-tool rig — saw its first signs of oil from the giant oilfield at a depth of 4,065 feet on June 13, 1928. It had been a long journey. (more…)

Oilfield production technologies began in Pennsylvania with an economical way to pump multiple wells.
In the earliest days of the petroleum industry, which began with an 1859 oil discovery in Pennsylvania, production technologies used steam power and a walking beam pump system that evolved into ways for economically producing oil from multiple wells.
Just as drilling technologies evolved from spring poles to steam-powered cable tools to modern rotary rigs, oilfield production also improved.

In the early days of the industry, oil production technology used steam power and a wooden walking beam. A steam engine at each well raised and lowered one end of the beam. An oil production technique perfected in Pennsylvania used central power for pumping low-production wells to economically recover oil.
Eccentric Wheels
A Library of Congress (LOC) photograph from 1909 shows a “double eccentric power wheel,” part of an innovative centralized power system. The oilfield technology from a South Penn Oil Company (the future Pennzoil) lease between the towns of Warren and Bradford, Pennsylvania.
The LOC photograph preserves the oilfield technology that used the two wheels’ elliptical rotation for simultaneously pumping multiple oil wells. The wheels’ elliptical rotation simultaneously pumped eleven remote wells. This central pump unit operated in the Morris Run oilfield, discovered in 1883. It was manufactured at the Titusville Iron Works.
Many oilfield history resources can be found in the Library of Congress Digital Collections and the related images of petroleum history photography. The development of centralized pumping systems — eccentric wheels and jerk lines — often are preserved in high-resolution files.
The Morris Run field in Pennsylvania produced oil from two shallow “pay sands,” both at depths of less than 1,400 feet. It was part of a series of other early important discoveries.

In 1881, the Bradford field alone accounted for 83 percent of all the oil produced in the United States (see Mrs. Alford’s Nitro Factory). In 2004, new technologies began producing natural gas from a far deeper formation, the Marcellus Shale.
Oil production from some of the earliest shallow Pennsylvania wells declined to only about half a barrel of oil a day, but some continued pumping into 1960. On the West Coast, a 1913 central pumping unit produced from California’s largest oilfield three decades longer.
Midway-Sunset Jack Plant
On June 9, 2023, the National Park Service added the Midway-Sunset Jack Plant to the National Register of Historic Places — thanks to Mark Smith, who submitted the application to preserve the facility. Installed by the Engineers Oil Company in 1913, the Kern County jack plant pumped oil until 1990.
In operation until 1990, California’s Midway-Sunset Jack Plant used eccentric-wheel technologies from the late 19th century. The Kern County plant pumped more than 1.5 million barrels of oil. Photos courtesy John Harte. Illustration courtesy San Joaquin Geological Society.
“The Midway-Sunset Jack Plant is an extremely rare example of central power and ‘jack-line’ oil pumping technology on its original site and housed in its original building,” Smith noted in his 45-page draft application to the State Historical Resources Commission. “Its design and operational history reflect significant advancements in oil extraction technology.”
According to company records, the jack plant’s slowly rotating eccentric wheels produced 1.5 million barrels of oil during its lifetime. The end came when the bearing of the vertical shaft became worn, causing the shaft to wobble. The wobble of the eccentric gears made the pumping of the wells out of balance.
Pumping Multiple Wells
As the number of oil wells grew in the early days of America’s petroleum industry in Pennsylvania, simple water-well pumping technologies began to be replaced with steam-driven walking-beam pumping systems.
At first, each well had an engine house where a steam engine raised and lowered one end of a sturdy wooden beam, which pivoted on the cable-tool well’s “Samson Post.” The walking beam’s other end cranked a long string of sucker rods up and down to pump oil to the surface.
America’s oilfield technologies advanced in 1875 with this “Improvement In Means For Pumping Wells” invented in Pennsylvania.
Recognizing that pumping multiple wells with a single steam engine would boost efficiency, on April 20, 1875, Albert Nickerson and Levi Streeter of Venango County, Pennsylvania, patented their “Improvement in Means for Pumping Wells.”
Their system was the forerunner of wooden or iron rod jerk line systems for centrally powered oil production. This technology, eventually replaced by counter-balanced pumping units, will operate well into the 20th century – and remain an icon of early oilfield production.
“By an examination of the drawing it will be seen that the walking beam to well No. 1 is lifting or raising fluid from the well. Well No. 3 is also lifting, while at the same time wells 2 and 4 are moving in an opposite direction, or plunging, and vice versa,” the inventors explained in their patent application (No. 162,406).
Central Power Units
“Heretofore it has been necessary to have a separate engine for each well, although often several such engines are supplied with steam from the same boiler,” noted Nickerson and Streeter.
“The object of our invention is to enable the pumping of two or more wells with one engine…By it the walking beams of the different wells are made to move in different directions at the same time, thereby counterbalancing each other, and equalizing the strain upon the engine.”

Steam initially drove many of these central power units, but others were converted to burn natural gas or casing-head gas at the wellhead – often using single-cylinder horizontal engines. Examples of the engines, popularly called “one lungers” by oilfield workers, have been collected and restored (see Coolspring Power Museum).

The heavy and powerful engine — started by kicking down on one of the iron spokes — transferred power to rotate an eccentric wheel, which alternately pushed and pulled on a system of rods linked to pump jacks at distant oil wells.
Pump Jacks
“Transmitting power hundreds of yards, over and around obstacles, etc., to numerous pump jacks required an ingenious system of reciprocating rods or cables called Central Power and jerker lines,” explains documentation from an Allegheny National Forest Oil Heritage Series.
The series documentation includes an early illustration of an oilfield “jack plant” in McKean County, Pennsylvania. The long rod lines were also called shackle lines or jack lines.
A single engine with eccentric wheel connecting rod lines could economically pump oil using Oil Well Supply Company’s “Simplex Pumping Jacks.”
Around 1913, with electricity not readily available, the Simplex Pumping Jack became a popular offering from Oil Well Supply Company of Oil City, Pennsylvania. The simple and effective technology could often be found at the very end of long jerk lines.
A central power unit could connect and run several of these dispersed Simplex pumps. Those equipped with a double eccentric wheel could power twice as many.
Roger Riddle, a retired field guide for the West Virginia Oil & Gas Museum in Parkersburg, grew up around central power units and recalls the rhythmic clanking of rod lines.
Riddle guided visitors through dense nearby woods where remnants of the elaborate systems rust. The heavy equipment once “pumped with just these steel rods, just dangling through the woods,” he said. “You could hear them banging along – it was really something to see those work. The cost of pumping wells was pretty cheap.”
The heyday of central power units passed when electrification arrived, nonetheless, a few such systems remain in use today. Learn more about the evolution of petroleum production methods, the first counter-balanced “Nodding Donkeys” in All Pumped Up – Oilfield Technology.

Drilling for water in 1894, Corsicana discovered an oilfield and became the richest town in Texas.
In the summer of 1894, town leaders of Corsicana, Texas, hired a contractor to drill a water well on 12th Street. The driller found oil instead. The small community’s oilfield discovery launched the first Texas oil boom seven years before a more famous gusher at Spindletop Hill far to the southeast.
Corsicana’s first oil well produced less than three barrels of oil a day, but it quickly transformed the sleepy agricultural town into a petroleum and industrial center. The discovery launched industries, including service companies and manufacturers of the newly invented rotary drilling rig.
The first Texas oil boom arrived in 1894 with discovery of the Corsicana oilfield by a drilling contractor hired by the city to find water. An annual Derrick Day Chili & BBQ Cook-Off celebrates the discovery. Colorized postcard of Navarro County oil wells, circa 1910.
Corsicana local historians consider the 1894 discovery well, drilled on South 12th Street, the first significant commercial oil discovery west of the Mississippi (Kansans claim the same distinction for an 1892 Neodesha oil well).
Early Texas Oilfields
The American Well and Prospecting Company (from Kansas) made the oil strike on June 9, 1894, at a depth of 1,035 feet. The city council — angry and still wanting water for its growing community 55 miles south of Dallas — paid only half of the drilling contractor’s $1,000 fee. (more…)

June 2, 1908 – Goose Creek Oilfield discovered –
Drilled on Galveston Bay wetlands, the first offshore well in Texas revealed a giant oilfield 20 miles southeast of Houston, according to the Texas State Historical Association (TSHA). Inspired by reports of bubbles on the surface where Goose Creek emptied into the bay, the Houston-based syndicate Goose Creek Production Company made the discovery at a depth of 1,600 feet.
A single well of the Goose Creek field in 1917 produced 35,000 barrels of oil a day from a depth of 3,050 feet. Circa 1919 photo by Frank Schlueter courtesy Library of Congress Prints and Photographs Division.
“Within days the syndicate sold out to a subsidiary of the Texas Company, the future Texaco,” notes TSHA, adding the Goose Creek field, “spurred exploration for deep-seated (salt) domes, and led to the discovery of some of the largest oilfields in the United States.”
In 1909, Howard Hughes Sr. secretly tested an experimental dual-cone rock bit at Goose Creek. Humble Oil and Refining Company constructed a refinery adjacent to the field In 1921, naming the site Baytown.
June 3, 1979 – Bay of Campeche Oil Spill
Drilling in about 150 feet of water, the semi-submersible platform Sedco 135 suffered a blowout 50 miles off Mexico’s Gulf Coast. The Pemex well Ixtoc 1 spilled 3.4 million barrels of oil before being controlled nine months later. Considering the spill’s size, the environmental impact proved less than expected, according to a 1981 report by the Coordinated Program of Ecological Studies in the Bay of Campeche. Surveys of Campeche Sound conducted in 1980 reported, “Evaporation, dispersion, photo-oxidation and biodegradation processes played a major role in attenuating the harmful environmental effects of the oil spill.”
June 4, 1872 – Pennsylvania Oilfields bring Petroleum Jelly
A young chemist living in New York City, Robert Chesebrough,
patented “a new and useful product from petroleum,” which he named “Vaseline.” His patent proclaimed the virtues of this purified extract of petroleum distillation residue as a lubricant, hair treatment, and balm for chapped hands.
Robert Chesebrough consumed a spoonful of Vaseline each day and lived to be 96 years old. Photo courtesy Drake Well Museum.
When the 22-year-old chemist visited the new Pennsylvania oilfields in 1865, he noted drilling was often confounded by a paraffin-like substance that clogged the wellhead. Drillers used the “rod wax” as a quick first aid for abrasions.
Chesebrough returned to New York City and worked in his laboratory to purify the well byproduct, which he first called “petroleum jelly.” Female customers would discover that mixing lamp black with Vaseline made an impromptu mascara. In 1913, Mabel Williams employed just such a concoction and it led to the founding of a cosmetic company.

June 4, 1892 – Devastation of Pennsylvania Oil Regions
After weeks of thunderstorms in Pennsylvania’s Oil Creek Valley, the Spartansburg Dam on Oil Creek burst, sending torrents of water that killed more than 100 people and destroyed homes and businesses in Titusville and Oil City. The disaster was compounded when fires broke out.

“This city during the past twenty-four hours has been visited by one of the most appalling fires and overwhelming floods in the history of this country,” reported the New York Times from Oil City. Oilfield photographer John A. Mather documented the devastation, which included his Titusville studio and 16,000 glass-plate negatives.

June 4, 1896 – Henry Ford drives his “Quadricycle”
Driving the first car he ever built, Henry Ford left a workshop behind his home on Bagley Avenue in Detroit, Michigan. He had designed his “Quadricycle” in his spare time while working as an engineer for Edison Illuminating Company. Ford chose the name because his handmade, 500-pound “horseless carriage” ran on four bicycle tires. Inspired by advancements in gasoline-fueled engines, he founded the Henry Ford Company in 1903.
June 4, 1921 – Petroleum Seismograph tested
A team of earth scientists tested an experimental seismograph device on a farm three miles north of Oklahoma City and determined it could accurately map subsurface structures. Led by Prof. John C. Karcher and W.P. Haseman, the team from the University of Oklahoma found that seismology could be useful for oil and natural gas exploration and production. Further seismic reflection tests, including one in the Arbuckle formation in August, confirmed their results.
June 6, 1932 – First Federal Gasoline Tax
The federal government taxed gasoline for the first time when the Revenue Act of 1932 added a one-cent per gallon excise tax to U.S. gasoline sales. The first state to tax gasoline was Oregon, which imposed a one-cent per gallon tax in 1919. Colorado, New Mexico, and other states followed. The federal tax, last raised on October 1, 1993, has remained at 18.4 cents per gallon (24.4 cents per gallon for diesel). About 60 percent of federal gasoline taxes are used for highway and bridge construction.
June 6, 1944 – English Channel Pipelines fuel WWII Victory
As the D-Day invasion began along 50 miles of fortified French coastline in Normandy, logistics for supplying the effort would include two top-secret engineering feats — the construction of artificial harbors followed by the laying of pipelines across the English Channel.
Operation PLUTO (Pipe Line Under The Ocean) unspooled flexible steel pipelines across the English Channel, but the channel was deep, the French ports distant.
Code-named “Mulberrys” and using a design similar to modern jack-up offshore rigs, the artificial harbors used barges with retractable pylons to provide platforms to support floating causeways extending to the beaches.
To fuel the Allied advance into Nazi Germany, Operation PLUTO (Pipe Line Under The Ocean) used flexible steel pipelines wound onto giant “conundrums” designed to spool off when towed. Gen. Dwight Eisenhower later acknowledged the vital importance of the oil pipelines.

June 6, 1976 – Oil Billionaire J. Paul Getty dies
With a fortune reaching $6 billion (about $32 billion in 2023), J. Paul Getty died at 83 at his estate near London. Born into his father’s petroleum wealth from the Oil Company of Tulsa, Getty made his first million by age 23 from buying and selling oil leases.
The J. Paul Getty Museum art collection is housed in the Getty Center (above) and the Getty Villa on the California Malibu coast.
“I started in September 1914, to buy leases in the so-called red-beds area of Oklahoma,” Getty once told the New York Times. “The surface was red dirt and it was considered impossible there was any oil there. My father and I did not agree and we got many leases for very little money which later turned out to be rich leases.”
Getty, who incorporated Getty Oil in 1942, gave more than $660 million from his estate to the J. Paul Getty Museum.
