Schlumberger
Schlumberger (French: [ʃlumbɛʁʒe, ʃlœ̃b-]), doing business as SLB, is a global multinational oilfield services company. Founded in France in 1926, the company is now incorporated as Schlumberger NV in Willemstad, Curaçao, with principal executive offices in Houston, Texas. As of 2022, it is both the world's largest offshore drilling company and the world's largest offshore drilling contractor by revenue.
Also known as Schlumberger Limited, the company trades on the New York Stock Exchange, Euronext Paris, the London Stock Exchange and SIX Swiss Exchange. In 2022, the Forbes Global 2000 ranked Schlumberger the 349th largest company in the world.
Schlumberger was founded in 1926 in Paris as the Electric Prospecting Company (French: Société de prospection électrique) by two brothers Conrad and Marcel Schlumberger from Alsace. Schlumberger supplies the petroleum industry with services such as seismic data processing, formation evaluation, well testing and directional drilling, well cementing and stimulation, artificial lift, well completions, flow assurance and consulting, and software and information management. The company is also involved in the groundwater extraction and carbon capture and storage industries.
The Schlumberger brothers had experience 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 electrical-measurement mapping services, and recorded the first-ever electrical resistivity well log in Merkwiller-Pechelbronn, France, in 1927. The company quickly expanded, logging its first well in the U.S. in 1929 in Kern County, California. In 1934, the Schlumberger Well Surveying Corporation was founded in Houston, later evolving into Schlumberger Well Services, and finally Schlumberger Wireline and 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 Limited businesses, which by now included American testing and production company Johnston Testers.[citation needed]
Over the years, Schlumberger continued to expand its operations and acquisitions. In 1960, Dowell Schlumberger (50% Schlumberger, 50% Dow Chemical), which specialized in pumping services for the oil industry, was formed. On February 2, 1962, Schlumberger Limited became listed on the New York Stock Exchange. That same year, Schlumberger purchased Daystrom, an electronic instruments manufacturer in South Boston, Virginia, which was making furniture by the time the division was sold to Sperry & Hutchinson in 1971. Schlumberger purchased 50% of Forex in 1964 and merged it with 50% of Languedocienne to create the Neptune Drilling Company. The first computerized reservoir analysis, SARABAND, was introduced in 1970. The remaining 50% of Forex was acquired the following year; Neptune was renamed Forex Neptune Drilling Company. In 1979, Fairchild Camera and Instrument (including Fairchild Semiconductor) became a subsidiary of Schlumberger Limited.
In 1981, Schlumberger established the first international data links with e-mail. In 1983, Schlumberger opened its Cambridge Research Center in Cambridge, England.
In 1984, the SEDCO drilling rig company and half of Dowell of North America were acquired, resulting in the creation of the Anadrill drilling segment, a combination of Dowell and The Analysts' drilling segments. Forex Neptune was merged with SEDCO to create the Sedco Forex Drilling Company the following year, when Schlumberger purchased Merlin and 50% of GECO.[citation needed]
In 1987, Schlumberger completed its purchases of Neptune (North America), Bosco and Cori (Italy), and Allmess (Germany). That same year, National Semiconductor acquired Fairchild Semiconductor from Schlumberger for $122 million.
