Carbonate-Reservoir Engineering

Djebbar Tiab, Ph.D.
Descripción del instructor

Is a Professor of Petroleum Engineering at the University of Oklahoma (OU). He received his B.Sc. (May 1974) and M.Sc. (May 1975) degrees from the New Mexico Institute of Mining and Technology, and Ph.D. degree (July 1976) from the University of Oklahoma - all in Petroleum Engineering, with a minor in mathematics. He served as the Director of the OU – Sonatrach “Graduate Program in Petroleum Engineering in Algeria” from 1996 to 2005. As a researcher at the University of Oklahoma, Dr. Tiab received several research grants and contracts from the National Science Foundation (NSF), United States Department of Energy, U.S. Department of HEW, SONATRACH, KOC, Oklahoma Mining and Mineral Resources Institute, EPSCoR and the Energy Resources Institute. He is a member of the U.S. Research Council, Society of Petroleum Engineers (SPE), Core Analysis Society, Pi Epsilon Tau, Who is who and American Men and Women of Science. He served as a technical editor of various SPE, Egyptian, Kuwaiti and U.A.E. journals. He was member of the SPE Pressure Analysis Transaction. He also served as a member of the University of Oklahoma Senate. He has served as a member of the College of Engineering Dean’s Advisory and as Chairman of the Ad hoc PGE Graduate Program Committee. In 2001 he was elected to the SPE Twenty-Five Year Club. Dr. Tiab is the author/co-author of over two hundred (200) conference and journal technical papers in the area of pressure transient analysis, dynamic flow analysis, Petrophysics, natural gas engineering, reservoir characterization, reservoir engineering and injection processes. In 1975 (M.S. thesis) and 1976 (Ph.D. dissertation) Tiab introduced the pressure derivative technique, which revolutionized the interpretation of pressure transient tests. He developed patents for CORE LAB in the area of reservoir characterization (identification of flow units). He is the senior author of the textbook “PETROPHYSICS”, published by Gulf Publishing Company: 1st Edition in October 1996; 2nd updated edition was published by Elsevier in January 2004. He is also working on the 3rd edition to be published in 2010, and on another manual titled “Horizontal Wells - Reservoir Performance”. He has co-authored three research books entitled “Productivity Equations for Oil Wells”, “Petroleum Reservoir Characterization – Interwell Connectivity”, published in June and July 2009 by VDM Publishing House, and “Analytical Solutions to Productivity and Pressure Transient Equations” published by VDM & LAP Lambert Academic Publishing AG& Co., August 2010. Dr. Tiab supervised one hundred forty research projects at the University of Oklahoma and two at Core Laboratories. These research projects formed the basis of 29 Ph.D. dissertations and 123 M.Sc. theses. The research projects covered all aspects of Petroleum Engineering including reservoir engineering, reservoir characterization, enhanced oil recovery and production. Most of his Ph.D. students are now consultants and/or professors at universities in the U.S.A., South America, Africa, Asia and the Middle East. The majority of his MS students (82) are currently working for Sonatrach in Algeria. He received the Outstanding Young Men of America Award (1983), the SUN Award for Education Achievement (1984), Kerr-McGee Distinguished Lecturer Award (1985), the College of Engineering Faculty Fellowship of Excellence (1986), the Halliburton Lectureship Award (1987-89), the UNOCAL Centennial Professorship (1995-98), and the P&GE Distinguished Professor (1999 – 2000). The UNOCAL Professorship was created to honor the one-hundredth anniversary of the University of Oklahoma. He received the 2007 USCO Recognition Award for Outstanding Technical Achievements. He received the prestigious 1995 SPE Distinguished Achievement Award for Petroleum Engineering Faculty. The citation read, “He is recognized for his role in student development and his excellence in classroom instruction. He pioneered the pressure derivative technique of well testing and has contributed considerable understanding to petrophysics and reservoir engineering through his research and writing.” Dr. Tiab has been elected in October 2002 to the Russian Academy of Natural Sciences as a member because of “His outstanding work in petroleum Engineering”, and was awarded the Kapista gold Medal of Honor for “His outstanding contributions to the field of engineering.” He received the 2003 SPE Formation Evaluation Award for “Outstanding achievements in petrophysics and reservoir engineering.” He is nominated for the 2010 SPE Reservoir Engineering Award.
