April 25, 1865 – Civil War Veteran patents Well Torpedo –
Civil War veteran Col. Edward A.L. Roberts of New York City received the first of his many patents for an “Improvement in Exploding Torpedoes in Artesian Wells.” The invention used controlled down-hole explosions “to fracture oil-bearing formations and increase oil production.” It was a major technological achievement for the young U.S. petroleum industry.

A marker notes the 1865 first demonstration of the invention of Union Col. E.A.L. Roberts.
Roberts torpedoes were filled with gunpowder, lowered into wells, and ignited by a weight dropped along a suspension wire to percussion caps. In later models, nitroglycerin replaced gunpowder. Before the well torpedo’s invention, many early wells in the new oil regions of Pennsylvania, New York, and West Virginia often produced limited amounts of oil.
With its exclusive patent licenses, the Roberts Petroleum Torpedo Company charged up to $200 per torpedo “shoot” and a one-fifteenth royalty. Seeking to avoid the expense, unlicensed practitioners operated at night with their own explosive devices, reportedly leading to the term “moonlighter.”

April 26, 1947 – Oil Industry promoted on Radio
For the first time since its establishment in 1919, the American Petroleum Institute launched a national advertising campaign. “The theme of the drive is that the petroleum industry is a modern and progressive one, and is now turning out the best products in its history,” noted The Billboard.

Founded in 1919 in New York City, API moved its headquarters to the nation’s capital in 1929.
“Radio this week struck real pay dirt as a ‘Gusher’ will come mainly from expansion of current air time on spot local or regional levels by the thousands of petroleum and related corporations,” explained the weekly publication. API today is a Washington, D.C.-based lobbying organization representing the largest U.S. petroleum companies. It issues industrywide recommended practices, “to promote the use of safe equipment and proven engineering.”

April 27, 1966 – Ariel Corporation founded
After receiving a degree in mechanical engineering in 1954, former eighth-grade teacher Jim Buchwald founded Ariel Corporation in Mount Vernon, Ohio. “With little money to pay for a facility to house the tools, a room in the basement of the Buchwald family home is cleaned up,” according to the Ariel website.
Buchwald bought a lathe, a small hand-cranked rotary table and a vertical drill for manufacturing valves. “This room becomes the first Ariel machine shop, with an adjoining room functioning as Ariel’s first official engineering department.”

By 1968, Buchwald had built a prototype gas compressor that ran at the unprecedented speed of 1,800 RPM. His Ohio machine shop soon transitioned into a manufacturing facility, and Buchwald named the company after his favorite 1948 Ariel motorcycle. His company has become one of the world’s largest manufacturers of reciprocating gas compressors.
April 29, 2004 – Last Oldsmobile rolls off Assembly Line
The last Oldsmobile ever built (Alero GLS model) left the company’s production line in Lansing, Michigan. Founded by Ransom E. Olds in 1897 as “Olds Motor Vehicle Company,” Olds sold America’s first mass-produced car, the Model R “Curved Dash,” from 1902 to 1907, according to Robert Domm’s Michigan Yesterday & Today. In 1908, Oldsmobile joined Buick to become part of the newly established General Motors (GM).
April 30, 1929 – Marland Oil and Continental Oil become Conoco
After discovering several Oklahoma oilfields, Marland Oil Company acquired Continental Oil Company to create a network of service stations in 30 states. Future Oklahoma Governor Ernest W. Marland had founded Marland Oil in 1921; Continental Oil Company was founded in 1875 in Utah, where it refined oil into kerosene.

After Continental Oil and Marland Oil combined in 1929, the new company used this logo until 1970.
Headquartered in Ponca City, the new company retained the name of Continental Oil, but adopted the well-known Marland red triangle trademark, replacing the “Marland Oils” text with “Conoco.” In 2002, the company merged with Phillips Petroleum (incorporated in 1917), to become ConocoPhillips.

April 30, 1955 – “Landmen” form Trade Association
The American Association of Professional Landmen (AAPL) organized as a petroleum landmen trade association in Fort Worth, Texas. Landmen research records to determine ownership, locate mineral and land owners and negotiate oil and natural gas leases, trades and contracts. With about 15,000 members in 2020, the association also has helped ensure compliance with state and federal regulations, according to AAPL.
May 1, 1860 – First West Virginia Oil Well
Virginia’s petroleum industry began about one year before the Civil War when John Castelli ”Cass” Rathbone found oil after drilling near Burning Springs Run in what today is West Virginia.
The Rathbone well reached 300 feet and began producing 100 barrels of oil a day. Rathbone partnered with his brother to drill more wells in valley of the Little Kanawha River southwest of Parkersburg. It was the first petroleum boom to take place outside the Pennsylvania oil region.

Following the 1860 oil discovery at Burning Springs, Appalachian drillers applied cable-tool technologies to drill deeper. Circa 1870 photo courtesy West Virginia Humanities Council.
By the end of 1860, the “Burning Springs Oil Rush” resulted in more than 600 oil leases registered in the Wirt County courthouse. Warehouses were built along the Little Kanawha River, which reached the Ohio River at Parkersburg.
“These events truly mark the beginnings of the oil and gas industry in the United States,” noted West Virginia historian David McKain in 1994, adding that the region’s sudden oil wealth helped bring about statehood in June 1863. Many of the new state’s early politicians were “oil men — governor, senator and congressman — who had made their fortunes at Burning Springs.”

May 1, 1916 – Harry Sinclair founds Sinclair Oil & Refining
Harry Ford Sinclair brought together a collection of several depressed oil properties, five small refineries and many untested leases — all acquired at bargain prices. He began with $50 million in assets and borrowed another $20 million to form Sinclair Oil & Refining Corporation.

An updated 70-foot Sinclair “Dino” traveled more 10,000 miles through 25 states following the New York World’s Fair in 1964-1965.
In its first 14 months, Sinclair’s New York-based company produced six million barrels of oil for a net income of almost $9 million. The company’s petroleum refining capacity grew to 150,000 barrels of oil a day in 1932.
Destined to become one of the oldest continuous names in the U.S. petroleum industry, in 1930 the company began using an Apatosaurus (then called a Brontosaurus) in its advertising, sales promotions and product labels. Visitors marveled at the green Jurassic giant at Sinclair Oil’s “Dinoland Pavilion” at the 1939-1940 New York World’s Fair– and again in 1964-65.

May 1, 1931 – Railroad Commission limits East Texas Oil Production
The first proration order from the Texas Railroad Commission (RRC) for the giant East Texas oilfield took effect after excessive production following the Daisy Bradford No. 3 well one year earlier caused an oil price collapse. With hundreds of wells producing almost one million barrels per day, oil prices had fallen to as low as 10 cents a barrel. The commission’s order — unpopular with independent producers but enforced by Texas Rangers — limited production and stabilized prices.

May 1, 2001 – Oklahoma Plaza honors Oil Pioneers
The Conoco Oil Pioneers of Oklahoma Plaza was dedicated at the Sam Noble Museum at the University of Oklahoma, Norman.

Thomas B. Slick relief at Conoco Oil Pioneers outdoor plaza at the Sam Noble Museum, University of Oklahoma, Norman.
“The history of the state of Oklahoma is inextricably linked with the remarkable history of the oil industry,” proclaimed Conoco Chairman Archie Dunham. “The individuals identified here are true Oklahoma oil pioneers in that their endeavors were most significant in the development of the oil and gas industry in this very young state.” Tom Slick is among those honored in the Conoco Plaza.

April 18, 1939 – Patent for perforating Well Casing –
Ira McCullough of Los Angeles patented a multiple bullet-shot casing perforator and mechanical firing system. He explained the object of his oilfield invention was “to provide a device for perforating casing after it has been installed in a well in which projectiles or perforating elements are shot through the casing and into the formation.”

Ira McCullough’s 1937 patent drawing for perforating wells.
The innovation of simultaneous firing from several levels in the borehole greatly enhanced the flow of oil. McCullough’s device included a “disconnectable means” that rendered percussion inoperative until the charges were lowered into the borehole, acting as “a safeguard against accidental or inadvertent operation.”
Another inventor, Henry Mohaupt, in 1951 would use World War II anti-tank technology to improve the concept by using a conically hollowed-out explosive for perforating wells.

April 19, 1892 – First U.S. Gasoline Powered Automobile
Brothers Charles and Frank Duryea test drove a gasoline powered automobile they had built in their Springfield, Massachusetts, workshop. Considered the first model to be regularly manufactured for sale in the United States, 13 were produced by the Duryea Motor Wagon Company. Other manufacturers followed the brothers’ example.

The Duryea brothers (above) built their cars in Springfield, Massachusetts.
In March 1896, the Duryea brothers sold their first Duryea motor wagon. It was reported two months later that in New York City a motorist driving a Duryea hit a bicyclist – reportedly the nation’s first recorded automobile traffic accident. By the time of the first U.S. automobile show in November 1900 at Madison Square Garden, of the 4,200 automobiles sold in the United States, gasoline powers less than 1,000.

April 20, 1875 – Improved Well Pumping Technology
Pumping multiple wells with a single steam engine boosted efficiency in early oilfields when Albert Nickerson and Levi Streeter of Venango County, Pennsylvania, patented their “Improvement In Means For Pumping Wells.” The new technology used a system of linked and balanced walking beams to pump oil wells.

U.S. oilfield technologies advanced in 1875 with an “Improvement In Means For Pumping Wells.”
“By an examination of the drawing it will be seen that the walking-beam to well No. l 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. Their system was the forerunner of rod-line (or jerk line) eccentric wheel systems that operated into the 20th century using iron rods instead of rope and pulleys.

April 20, 1892 – Prospector discovers Los Angeles City Oilfield
The giant Los Angeles oilfield was discovered when a struggling prospector, Edward Doheny, and his mining partner Charles Canfield drilled into the tar seeps between Beverly Boulevard and Colton Avenue. Their well produced about 45 barrels of oil a day.

Artfully camouflaged petroleum production continues today in downtown Los Angeles. Edward Doheny discovered the oilfield in 1892. Photo courtesy the Center for Land Use Interpretation, Culver City, California.
Although the first California oil well had been drilled after the Civil War, Doheny’s 1892 discovery (near present-day Dodger Stadium) launched California’s petroleum industry. In 1897, about 500 Los Angeles City wells pumped more than half of the state’s annual production of 1.2 million barrels of oil. By 1925, California supplied half of the world’s oil.

April 20, 2010 – Deepwater Horizon Gulf of Mexico Disaster
At 10 a.m., while completing a well in the Macondo Prospect, 50 miles off the Louisiana coast, the Deepwater Horizon exploded and sank, killing 11 and injuring another 17 workers. An estimated 3.2 million barrels of oil flowed into the Gulf of Mexico after the platform’s 400-ton blowout preventer failed, resulting in the largest accidental marine oil spill in U.S. history.

Six months earlier at another site, the advanced, semi-submersible drilling rig had set a world record for the deepest offshore well (35,050 feet vertical depth in 4,130 feet of water). When the Macondo Prospect well was capped in mid-July, a National Commission on the Deepwater Horizon Oil Spill and Offshore Drilling launched an eight-month investigation. The commission released its final report on January 11, 2011.
April 22, 1926 – Osage Oil Lease Auctioneer Statue dedicated
A statue commemorating the friendship between Colonel E.E. Walters and Osage Indian Chief Baconrind (phonetically, Wah-she-hah) was dedicated in Walters’ hometown of Skedee, Oklahoma. Beginning in 1912, Colonel Elmer Ellsworth Walters (his real name) and the popular Chief of the Osage Nation raised millions of dollars for the tribe from mineral lease sales.

The auctions took place beneath an elm tree at the Tribal Council House in Pawhuska, where crowds gathering to witness bidding from Frank Phillips, E.W. Marland and William Skelly. The Skedee unveiling revealed “painted bronze” statues of Walters and the Chief Baconrind shaking hands on a sandstone base.

April 23, 1878 – Oil Exchange Building opened in Pennsylvania
The Oil Exchange of Oil City, Pennsylvania, opened a new, $100,000 brick building on Seneca Street. Independent producers began meeting there to trade oil and pipeline certificates. They had earlier gathered at local hotels or along Oil City’s Centre Street, then known as the “Curbside Exchange.”

By 1877, Pennsylvania oil companies had created the third largest financial exchange of any kind in America, behind only New York and San Francisco. Photo courtesy Library of Congress.
Before the 1870s, most Pennsylvania oil buyers had taken on-site delivery of oil in wooden barrels they provided themselves. A rapidly growing oil pipeline infrastructure created the need for a place to trade certificates as oil commerce expanded. The Standard Oil Company of New Jersey would bring an end to Pennsylvania’s highly speculative oil-trading markets.

April 24, 1911 – Magnolia Petroleum founded
The Magnolia Petroleum Company was founded as an unincorporated joint-stock association — a consolidation of several companies, the first of which began as a small refinery in Corsicana, Texas, in 1898.

Magnolia adopted a “Pegasus” logo in the 1930s.
After Magnolia Petroleum established service stations in southwestern states, Standard Oil Company of New York (Socony) began acquiring the company in 1925 before merging with the Vacuum Oil Company in 1931. The new company, Socony-Vacuum Oil (the future Mobil Oil), included stations in 20 states operated by Magnolia Petroleum, headquartered in a Dallas skyscraper. Magnolia adopted the Socony-Vacuum Oil Pegasus logo, which began rotating atop the building in 1934.

April 24, 1917 – Petroleum Product for Eyelashes trademarked
Tom Lyle Williams, doing business in Chicago as Maybell Laboratories, trademarked the name “lash-brow-ine” as a mascara and “preparation for stimulating the growth of eyebrows and eyelashes.” Two years earlier, Williams had watched his sister Mabel perform what she called “a secret of the harem,” mixing petroleum jelly with coal dust and applying it to her eyelashes.

A 1937 Maybelline magazine ad.
The mascara’s key ingredient, Vaseline, had been patented in 1872 by Robert Chesebrough, a young chemist in Brooklyn, New York. Williams began selling tins of Mabel’s mixture by mail-order catalog, calling it “lash-brow-ine.” In honor of his sister, who worked with him in his Chicago office, Williams renamed the mascara “Maybelline.”
