Prof. Djebbar Tiab is the Senior Professor of Petroleum Engineering at the University of Oklahoma and Petroleum Engineering consultant. 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 is the Director of "The University of Oklahoma Graduate Program in Petroleum Engineering in Algeria", which started in July 1997 on the campus of the Algerian Petroleum Institute (IAP), and is expected to last 8 years.

Before joining the University of Oklahoma in 1977, he worked as an assistant professor at the New Mexico Institute of Mining and Technology, where he taught drilling & well completion, production engineering, well logging and natural gas engineering. At the University of Oklahoma, Dr. Tiab taught various petroleum and general engineering courses including: oil reservoir engineering, natural gas engineering, reservoir mechanics lab, natural gas engineering lab, well test analysis, fluid mechanics, properties of reservoir fluids, introduction to engineering, advanced reservoir engineering, advanced
natural gas engineering, petrophysics, advanced petrophysics, petrophysics lab, water flooding, improved oil recovery, and advances in pressure transient analysis.

Prof. Tiab has consulted for a number of oil companies and offered training programs in petroleum engineering in the U.S.A. and overseas. He worked for over two years in the oil fields of Algeria for Alcore, S.A., an association of Sonatrach and Core Laboratories. He has also worked and consulted for Core Laboratories and Western Atlas in Houston, Texas, for four years (1989-1993) as a Senior Reservoir Engineer Advisor.

As a researcher at the University of Oklahoma, Prof. Tiab received several research grants from the National Science Foundation (NSF), United States Department of Energy, U.S.
Department of HEW, oil companies, 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 and U.A.E. journals. He is currently a member of the SPE Pressure Analysis Transaction Committee, and SPE Twenty-Five Year Club.

Prof. Tiab is the author of over one hundred thirty journal and conference technical papers in the area of pressure transient 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 two patents 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 edition will be out in December 2003. He is also working on a book titled "Well Test Synthesis".

Prof. Tiab supervised 20 Ph.D. and 95 M.Sc. students at the University of Oklahoma. Most of his Ph.D. students are now professors at universities in the U.S.A., South America, Africa, Asia and the Middle East. 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 also 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."
