Conrad Schlumberger
Conrad Schlumberger (1878-1936), a German geophysicist who invented, with his brother Marcel, electrical well logging, a technology that eliminated much of the guesswork associated with determining whether a formation holds oil or natural gas (1921). Electric well logs record the conductivity of interstitial water in rocks, the movement of drilling mud into porous strata, and the movement of formation water into the well bore. In 1927, a 1,640-ft (500-m) well in France’s Pechelbronn field successfully employed the world’s first electric log using successive resistivity readings to create a resistivity curve.
