Inventing the Electric Submersible Pump
Armais Arutunoff designed a downhole centrifugal pump and founded an oilfield service company.
The modern petroleum industry owes a lot to the son of an Armenian soap maker.
With the help of a prominent Oklahoma oil company president in the 1930s, Armais Sergeevich Arutunoff designed and built the earliest practical, downhole electric submersible pump. His invention would enhance oilfield production in wells worldwide.
Armais Arutunoff (1893-1978), inventor of the modern electric submersible pump.
A 1936 Tulsa World article described the Arutunoff electric submersible pump (ESP) as “an electric motor with the proportions of a slim fence post which stands on its head at the bottom of a well and kicks oil to the surface with its feet.”
By 1938, an estimated two percent of all oil produced in the United States with artificial lift was lifted by an Arutunoff pump (see All Pumped Up – Oilfield Technology).
Early Downhole Patents
The first patent for an oil-related electric pump was issued in the late 19th century during the growth of electrical power generation, according to a September 2014 article in the Journal of Petroleum Technology (JPT).
In 1894, a design by Harry Pickett (patent no. 529,804) used a downhole rotary electric motor with “a Yankee screwdriver device to drive a plunger pump.”
Expanding Picket’s concept, Robert Newcomb in 1918 received a patent for his “electro-magnetic engine” driving a reciprocating plunger.
“Heretofore, in very deep wells the rod that is connected to the piston, and generally known as the ‘sucker’ rod, very often breaks on account of its great length and strains imposed thereon in operating the piston,” noted Newcomb in his patent application.
Armais Arutunoff obtained 90 patents, including one in 1934 for an improved well pump and electric cable. At right is a 1951 “submergible” Reda advertisement.
Although several patents followed those of Picket and Newcomb, the Journal reports, “It was not until 1926 that the first patent for a commercial, operatable ESP was issued — to ESP pioneer Armais Arutunoff. The cable used to supply power to the bottomhole unit was also invented by Arutunoff.”
Reda: Russian Electrical Dynamo of Arutunoff
Arutunoff built his first ESP in 1916 in Germany, according to the Oklahoma Historical Society. “Suspended by steel cables, it was dropped down the well casing into oil or water and turned on, creating a suction that would lift the liquid to the surface formation through pipes,” reported OHS historian Dianna Everett.
After immigrating to the United States in 1923, in California Arutunoff could not find financial support for manufacturing his pump design. He moved to Bartlesville, Oklahoma, in 1928 at the urging of a new friend — Frank Phillips, head of Phillips Petroleum Company.
“With Phillips’s backing, he refined his pump for use in oil wells and first successfully demonstrated it in a well in Kansas,” noted Everett. The device was manufactured by a small company that soon became Reda Pump.
The name Reda – Russian Electrical Dynamo of Arutunoff – was the cable address of the company that Arutunoff originally started in Germany. The inventor would move his family into a Bartlesville home just across the street from Frank Phillips’ mansion.

A holder of more than 90 patents in the United States, Arutunoff was inducted into the Oklahoma Hall of Fame in 1974. “Try as I may, I cannot perform services of such value to repay this wonderful country for granting me sanctuary and the blessings of freedom and citizenship,” Arutunoff said at the time.
A modern ESP applies artificial lift by spinning the impellers on the pump shaft, putting pressure on the surrounding fluids and forcing them to the surface. It can lift more than 25,000 barrels of fluids per day. Courtesy Schlumberger.
Arutunoff died in February 1978 in Bartlesville. At the end of the twentieth century, Reda was the world’s largest manufacturer of ESP systems. It is now part of Schlumberger.
Armais Sergeevich Arutunoff was born to Armenian parents in Tiflis, part of the Russian Empire, on June 21, 1893. His hometown in the Caucasus Mountains dated back to the 5th Century. His father was a soap manufacturer and his grandfather a fur trader.
Centrifugal Pumps
As a young scientist, Arutunoff’s research convinced him that electrical transmission of power could be efficiently applied to oil drilling and improve the antiquated methods he saw in use in the early 1900s in Russia.
A small, yet high-horsepower electric motor was needed, but limitations imposed by the available casing sizes required a relatively small motor.
A motor of small diameter was too low in horsepower for the job, Arutunoff discovered. He studied the fundamental laws of electricity seeking answers to how to build a higher horsepower motor exceedingly small in diameter.
By 1916, Arutunoff was designing a centrifugal pump to be coupled to the motor for de-watering mines and ships. To develop enough power, the motor needed to run at very high speeds. He successfully designed a centrifugal pump, small in diameter and with stages to achieve high discharge pressure.
Arutunoff designed a motor ingeniously installed below the pump to cool the motor with flow moving up the oil well casing, and the entire unit was suspended in the well on the discharge pipe. The motor, sealed from the well fluid, operated at high speed in oil.
Although Arutunoff built the first centrifugal pump while living in Germany, he built the first submersible pump and motor in the United States while living in southern California.
Friend of Frank
Arutunoff already had formed Reda to manufacture his idea for electric submersible motors, and after living in Germany, Arutunoff came to the United States with his wife and one-year-old daughter to settle in Michigan, and then Los Angeles.
However, after emigrating to America in 1923, Arutunoff could not find financial support for his downhole production technology. Everyone he approached turned him down, believing his downhole concept was impossible under the “laws of electronics.”
No one would consider his inventions until a friend at Phillips Petroleum Company — Frank Phillips — encouraged him to form his own company in Bartlesville. The Arutunoff family moved into a house on the same street as the Phillips home.
Arutunoff’s manufacturing plant in Bartlesville spread over nine acres, employing hundreds during the Great Depression.
In 1928 Arutunoff moved to Bartlesville, where he formed Bart Manufacturing Company, which changed its name to Reda Pump Company in 1930. He soon demonstrated a working model of an oilfield electric submersible pump.
One of his pump-and-motor devices was installed in an oil well in the El Dorado field near Burns, Kansas — the first equipment of its kind to be used in a well. One reporter telegraphed his editor, “Please rush good pictures showing oil well motors that are upside down.”
By the end of the 1930s, Arutunoff’s company held dozens of patents for industrial equipment, leading to decades of success and even more patents. His “Electrodrill” aided scientists in penetrating the Antarctic ice cap for the first time in 1967.
Arutunoff oilfield technologies had a significant impact on the petroleum industry — quickly proving crucial to successful production for hundreds of thousands of U.S. oil wells.
