Schlumberger is incorporated in Willemstad, Curaçao as Schlumberger N.V.[7] and trades on the New York Stock Exchange, Euronext Paris, the London Stock Exchange and SIX Swiss Exchange.[8] Schlumberger is a Fortune Global 500 company, ranked 287 in 2016,[9] and also listed in Forbes Global 2000, ranked 176 in 2016.[10]


Schlumberger was founded in 1926 by Alsatian German brothers Conrad and Marcel Schlumberger from the Alsace region in France as the Electric Prospecting Company (French: Société de prospection électrique). The company recorded the first-ever electrical resistivity well log in Merkwiller-Pechelbronn, France in 1927. Today Schlumberger supplies the petroleum industry with services such as seismic acquisition and 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[11] and carbon capture and storage industries.[12]

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 1935, the Schlumberger Well Surveying Corporation was founded in Houston, later evolving 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 businesses, which by now included American testing and production company Johnston Testers.

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. In 1962, Schlumberger Limited became listed on the New York Stock Exchange.[13] 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.[14] 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 their Cambridge Research Center in Cambridge, England and in 2012 it was renamed the Schlumberger Gould Research Center after the company's former CEO Andrew Gould.[15]

The SEDCO drilling rig company and half of Dowell of North America were acquired in 1984, 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.

In 1987, Schlumberger completed their 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.[16] In 1991, Schlumberger acquired PRAKLA-SEISMOS, and pioneered the use of geosteering to plan the drill path in horizontal wells.

In 1992, Schlumberger acquired software company GeoQuest Systems. With the purchase came the conversion of SINet to TCP/IP and thus internet capable. In the 1990s Schlumberger bought out the petroleum division, AEG meter, and ECLIPSE reservoir study team Intera Technologies Corp. A joint venture between Schlumberger and Cable & Wireless resulted with the creation of Omnes, which then handled all of Schlumberger's internal IT business. Oilphase and Camco International were also purchased.

In 1999, Schlumberger and Smith International created a joint venture, M-I L.L.C., the world's largest drilling fluids (or mud) company. The company consists of 60% Smith International, and 40% Schlumberger. Since the joint venture was prohibited by a 1994 antitrust consent decree barring Smith from selling or combining their fluids business with certain other companies, including Schlumberger, the U.S. District Court in Washington, D.C. found Smith International Inc. and Schlumberger Ltd. guilty of criminal contempt and fined each company $750,000 and placed each company on five years probation. Both companies also agreed to pay a total of $13.1 million, representing a full disgorgement of all of the joint venture's profits during the time the companies were in contempt.[17]

In 2000, the Geco-Prakla division was merged with Western Geophysical to create the seismic contracting company WesternGeco, of which Schlumberger held a 70% stake, the remaining 30% belonging to competitor Baker Hughes. Sedco Forex was spun off, and merged with Transocean Drilling company in 2000.

In 2001, Schlumberger acquired the IT consultancy company Sema plc for $5.2 billion. The company was an Athens 2004 Summer Olympics partner, but Schlumberger's venture into IT consultancy did not pay off, and divestiture of Sema to Atos Origin was completed that year for $1.5 billion. The cards division was divested through an IPO to form Axalto, which later merged with Gemplus to form Gemalto, and the Messaging Solutions unit was spun off and merged with Taral Networks to form Airwide Solutions. In 2003, the Automated Test Equipment group, part of the 1979 Fairchild Semiconductor acquisition, was spun off to NPTest Holding, which later sold it to Credence.

In 2004, Schlumberger Business Consulting was launched. Based in Paris, it is the company's management consultancy arm. [18]

In 2005, Schlumberger purchased Waterloo Hydrogeologic,[19] which was followed by several other groundwater industry related companies, such as Westbay Instruments, and Van Essen Instruments. Also that year, Schlumberger relocated its U.S. corporate offices from New York to Houston.[20]

In 2006, Schlumberger purchased the remaining 30% of WesternGeco from Baker Hughes for US$2.4 billion.[21] Also that year, the Schlumberger-Doll Research Center was relocated to a newly built research facility in Cambridge, Massachusetts to replace the Ridgefield, Connecticut research center. The facility joins the other research centers operated by the company in Cambridge, England; Moscow, Russia; Stavanger, Norway; and Dhahran, Saudi Arabia.[22]

In 2010, the acquisition of Smith International in an all-stock deal valued at $11.3 billion was announced. The sale price is 45.84-a-share price was 37.5 percent higher than Smith closing price on 18 February 2010. The deal is the biggest acquisition in Schlumberger history.[23] The merger was completed on August 27, 2010.[24] Also announced in 2010 were Schlumberger plans to acquire Geoservices, a French-based company specializing in energy services, in a deal valued at $1.1 billion, including debt.[25]

In 2014, Schlumberger announced the purchase of the remaining shares of SES Holdings Limited (“Saxon”), a Calgary-based provider of international land drilling services, from First Reserve and certain members of Saxon management. The transaction is subject to customary closing conditions, including the receipt of regulatory approvals. Schulmberger had a minority share in Saxon previously.[26]

In 2015, Schlumberger was indicted by the US Department of Justice for sanction violations of conducting business in Iran and Sudan; the company was fined $233 million, amounting to the largest fine for sanctions to date.[27]

In 2015, due to a downturn in the global oil and gas industry, Schlumberger announced 21,000 layoffs accounting for 15% of the company's total workforce.[28]

In August 2015, Schlumberger agreed to acquire oilfield equipment manufacturer Cameron International for $14.8 billion.[29]

In January 2018, Schlumberger announced that WesternGeco would be exiting the seismic acquisition business, both onshore and offshore, while retaining its multiclient data processing and interpretation segments. This decision followed the bankruptcy filings of several competitors in the seismic services sector.[30]

Corporate affairs

United States

Schlumberger maintains a 33-acre (13 ha) campus at the northeast corner of U.S. Highway 90A and Gillingham Lane in Sugar Land, Texas; as of 2017 Schlumberger is the third largest employer in the city. In 2015 Schlumberger announced that it was moving its U.S. corporate headquarters to the Sugar Land facility from its Houston office building. The company plans to build new buildings with a scheduled completion time of late 2017. They include a total of 250,000 square feet (23,000 m2) of Class A office space and an "amenities" building with 100,000 square feet (9,300 m2) of space.[33]

In the 1930s the North American headquarters were established in Houston. In the 1970s, the company's top executives in North America were relocated to New York City. By 2006, the head office had 50 executives and support staff. By that year the company was moving that office to a building near the Houston Galleria.[34]

Schlumberger moved its Houston-area offices from 5000 Gulf Freeway in Houston to the Sugar Land campus in 1995.[35][36][37]

Environmental record

In 2009, Newsweek released their "Green Rankings" [38] a ranking of the 500 largest corporations on track records on a number of environmental issues. Schlumberger was ranked 118th out of 500 overall, and 3rd out of 31 in their industry. Newsweek remarked that to mitigate global warming Schlumberger has invested in carbon sequestration which involves long-term storage of CO2 and that the company's seismic survey ships are 20% to 25% more fuel-efficient than those of other seismic contractors from using fuels that emit less pollution and towing equipment that creates less drag on the vessels.[39]

Radioactive Sources

In 2006, a radioactive canister imported by Schlumberger was recovered in the Western Australian outback desert.[40] The canister had been lost by the company's transport partner, when the improperly secured container fell off the trailer on which it was being transported.[41]

In 2010, the Aberdeen Sheriff court fined Schlumberger Oilfield UK £300,000 for losing a radioactive source on the rig floor on the Ensco 101 mobile drilling rig in the North Sea for 4 hours.[42]


In 2009, the Pennsylvania Department of Environmental Protection fined Chesapeake Appalachia LLC and Schlumberger Technology Corp. more than $15,500 each for a hydrochloric acid spill in February 2009 at Chesapeake's Chancellor natural gas well site in Asylum Township, Bradford County, Pennsylvania. Officials said the leak did not contaminate groundwater.[43]


In 2006, as the current owner of a facility in Pickens, South Carolina, Schlumberger agreed to pay $11.8 million to federal and state agencies for a problem caused by the previous owner, Sangamo-Weston, a capacitor manufacturing plant. The cause of the problem was from polychlorinated biphenyls (PCB) released into the environment by Sangamo-Weston from 1955 to 1987. According to the Justice Department's Environment and Natural Resources Division, an additional agreement by Schlumberger to purchase and remove dams will directly improve the Twelvemile Creek, South Carolina ecosystem and provide significant environmental benefits for the affected communities.[44]

Deepwater Horizon

Schlumberger was contracted to perform wireline logging on the Deepwater Horizon oil rig in the Gulf of Mexico in 2010. However, the wireline log was cancelled and the Schlumberger standby crew was released by BP and left the rig earlier on the same day of the Deepwater Horizon explosion.[45]
