Conrad Schlumberger

Born 2 Oct 1878; died 1936 .German geophysicist and petroleum engineer noted for the invention, in 1927, of a method of continuous electric logging of boreholes. Beginning in 1912, Conrad Schlumberger conceived the idea for electrical measurements to map subsurface rock bodies. He was first joined by his brother, Marcel, in 1919 for work together in Normandy, France, opening their first office in 1921. For three years from 1923, Schlumberger teams conducted geophysical surveys in Romania, Serbia, Canada, South Africa, Belgian Congo and the U.S. Electrical prospecting was used for the first time to map a subsurface oil-bearing structure - a salt dome in Romania. In 1927, the first electrical resistivity log was recorded in a well in Pechelbronn, France.
