Formation Evaluation with Pre-Digital Well Logs

Richard M. Bateman was educated in the UK obtaining his M.A. in Natural Science, Physics from Oxford University. He began his career in the oil industry in South America as a field engineer for Schlumberger. He worked in many North and South American field locations and later spent three years at the Schlumberger Doll Research Centre in Ridgefield, Connecticut. He subsequently joined Amoco International Oil Company (now BP) and travelled extensively throughout the world from their Chicago headquarters finding oil and gas and teaching others how to do so. Richard has also held posts as Chief Petrophysicist of Halliburton Logging Services, Engineering Manager for Bridas (now Pan American Energy), Manager for Gaffney Cline and Associates’ Latin American operations, based in Buenos Aires, and as a well log interpretation and petrophysics instructor for PetroSkills/OGCI. Richard has authored four books and multiple patents and technical papers. He is a Senior and Life Member of the SPE and is also active with the SPWLA and the SCA. Richard recently retired as a member of the faculty of Texas Tech University as an Associate Professor in the Petroleum Engineering Department.
