Schlumberger Conrad (b. 1878-10-02 / d. 1936-05-09)
In 1912, Conrad conceived the revolutionary idea of using electrical measurements to map subsurface rock bodies in order to acquire information about the nature of the rock (chalk, sandstone, granite,etc.) and the presence of hydrocarbons. In 1919, Marcel began working with his brother and in 1920 they opened their first office in Paris. In 1927, the Schlumberger brothers produced the first measurements (Electric Log) of an oil well in France. These ideas were very successful, and they founded the Société de Prospection Électrique in 1926 and Schlumberger Well Surveying Corporation (now Schlumberger Well Services) in 1934.
