Schlumberger was founded by the two Schlumberger brothers who invented wireline resistivity logging as a technique for obtaining downhole data in oil and gas wells. Today, our commitment to technology innovation continues to provide the cornerstone for developing new generations of solutions that meet the changing needs of our customers. |
