Quick Answer
SLB was founded by Conrad Schlumberger, Marcel Schlumberger in 1926 in Houston, Texas. The company is currently led by Olivier Le Peuch.
Conrad Schlumberger arrived in the Pechelbronn oilfield in Alsace in September 1927 with an apparatus he had spent years developing in his laboratory at the Paris School of Mines: a cylindrical probe containing electrodes that could measure the electrical resistance of rock formations when lowered into a borehole. The measurement he took on that September day — the world's first electrical resistivity log — gave oil engineers their first empirical tool for understanding what lay beneath the surface without pulling core samples. Schlumberger had invented well logging. Conrad and his brother Marcel had founded their Paris company in 1926 on a theoretical insight: that different rock formations conduct electricity differently, and therefore that the electrical resistance profile of a borehole wall could reveal whether the formation contained oil, gas, water, or dry rock. The idea was scientifically obvious in retrospect. Before Schlumberger, oilfield geology was based on surface mapping and intuition. The brothers built the business through the 1930s by demonstrating wireline logging's practical value in oilfields across Europe, the Soviet Union, and eventually North America. Marcel led the American push, establishing operations in Houston and then across the producing basins of Texas and Oklahoma. The company's early clients were skeptical that an instrument measurement could replace the judgment of an experienced geologist. The logs proved them wrong consistently enough that by the late 1930s, major oil companies would not drill without a Schlumberger wireline service. World War II interrupted operations and forced a strategic decision: the family moved the company's effective headquarters to the United States, a shift that made Houston the center of what had been a French-founded enterprise. The postwar oil boom in the Gulf Coast and the Middle East gave Schlumberger the scale to invest in the next generation of measurement tools — nuclear logging in 1962, which used gamma rays and neutron bombardment to characterize formations that electrical resistivity could not read clearly. Each generation of tool extended the company's lead over competitors who were still catching up to the previous generation.
Conrad Schlumberger co-founded the company in 1926 with a singular focus on applying electrical physics to subsurface exploration, but his defining moment came in 1927 when he executed the first wireline resistivity measurement in Pechelbronn, France, permanently transforming oil exploration from geological guesswork into a precise, data-driven science.
Marcel Schlumberger co-founded the company in 1926, providing the critical business acumen and commercial strategy to scale Conrad's scientific inventions, but his defining moment arrived during World War II when he relocated the company's core intellectual property and leadership to the United States, ensuring the company's survival and post-war global dominance.
Marcel Schlumberger was a visionary engineer and businessman who partnered with his brother Conrad to commercialize their revolutionary wireline logging technology. While Conrad focused on the physics and sensor development, Marcel managed the complex logistics, international partnerships, and commercial strategy required to sell their services to the world's major oil companies. Following Conrad's death in 1936, Marcel assumed sole leadership of the company, navigating the treacherous geopolitical landscape of pre-war Europe. When Germany invaded France in 1940, Marcel made the critical decision to flee to the United States, carrying the company's proprietary schematics and core engineering team. He established Schlumberger Well Surveys in Houston, Texas, forging vital relationships with the US military and the domestic oil industry. Marcel's strategic foresight in relocating the company's intellectual capital to the US not only ensured the company's survival during the war but positioned SLB to dominate the post-war boom in Middle Eastern and global oil exploration, cementing his legacy as the architect of the company's global footprint.
