Schlumberger was founded in 1926 by the Conrad brothers and Marcel Schlumberger from the Alsace region in France as an Electric Prospecting Society. The company recorded the first record of electrical resistivity wells in Merkwiller-Pechelbronn, France in 1927. Today, Schlumberger supplies the oil industry with services such as seismic acquisition and processing, training assessment, well testing and directional drilling, cementation And well stimulation, elevation, well completion, flow assurance and consulting, and software and information management. The company also participates in the industries of groundwater extraction and carbon capture and storage.
The brothers had experience in conducting geophysical surveys in countries such as Romania, Canada, Serbia, South Africa, the Democratic Republic of the Congo and the United States. The new company sold electric measurement mapping services and recorded the first record of electrical resistivity wells in Merkwiller-Pechelbronn, France in 1927. The company expanded rapidly, registering its first well in the United States in 1929, Kern, California. In 1935, the Schlumberger Well Surveying Corporation was founded in Houston, which later evolved into Schlumberger Well Services and finally Schlumberger Wireline & Testing. Schlumberger invested heavily in research, inaugurating the Schlumberger-Doll Research Center in Ridgefield, Connecticut, in 1948, contributing to the development of a number of new logging tools. In 1956, Schlumberger Limited was incorporated as a holding company for all Schlumberger companies, which now included US testing and production company Johnston Testers.
Over the years, Schlumberger continued to expand its operations and acquisitions. In 1960, Dowell Schlumberger (50% of Schlumberger, 50% of Dow Chemical) was formed, specializing in pumping services for the oil industry. In 1962, Schlumberger Limited was listed on the New York Stock Exchange. That same year, Schlumberger bought Daystrom, a maker of electronic instruments in South Boston, Virginia, which manufactured furniture at the time the division was sold to Sperry & Hutchinson in 1971. Schlumberger bought 50% of Forex in 1964 and merged it with The 50% of Languedocienne to create the company of drilling of Neptune.
