Formation Evaluation with Pre-Digital Well Logs covers the practical use of legacy materials for formation evaluation using wireline logging equipment from 1927 until the introduction of digital logging in the 1960s and '70s. The book provides powerful interpretation techniques that can be applied today when an analyst is faced with a drawer full of old "E logs." It arms the engineer, geologist and petrophysicist with the tools needed to profitably plan re-completions or in-fill drilling in old fields that may have been acquired for modern deeper and/or horizontal drilling.
- Includes more than 150 figures, log examples, charts and graphs
- Provides work exercises for the reader to practice log analysis and formation evaluation
- Presents an important source for academia, oil and gas professionals, service company personnel and the banking and asset evaluation teams at consultancies involved in reserve and other property evaluation

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.
