This book Drilling Engineering,J.J.Azar & G.Robello Samuel,Pennwell,2007
Drilling engineering is a challenging discipline in the oil patch. It goes beyond what is found in textbooks
The technological advances in the past two decades have been very significant. These advances have
allowed the oil industry worldwide to economically and successfully exploit oil and gas fields that may have not been possible before
Dr. J. J. Azar , PhD, PE, SPE, NAE, is a professor emeritus of Petroleum Engineering at the University of Tulsa. He joined the university in 1965 as an assistant professor in Mechanical/ Aerospace Engineering, and was promoted to associate professor in 1969. In 1975, he joined the Petroleum EngineeringDepartment as full professor and Director of the University of Tulsa Drilling Research Projects, a joint oil and gas industry research program. In 1996, he stepped down from the directorship to devote full time to teaching and writing. He served as acting chairman of the Petroleum Engineering Department in 2001. Dr.Azar officially retired from the University May 31, 2002, to pursue his own activities in teaching and consulting. Professor Azar is a world-renowned lecturer and researcher in drilling engineering. As a director of drilling research, he is credited with building one of the most comprehensive and top drilling engineering curricula in the Department of Petroleum Engineering at the University of Tulsa, worldwide. He has led his graduate students to pioneering research work in areas of cuttings transport in directional well drilling, drilling fluids hydraulics, drill bit, and drill string dynamics. He is closely associated and worked with all major oil and gas companies across the globe. His contributions to the advancement of drilling technology through teaching, research, and publications are notable. He is the author and/or coauthor of four textbooks and more than 60 publications in refereed technical journals.

several technical conferences. Professor Azar was a participant speaker at the Advances in Drilling Technologies” workshop organized by the U.S. National Research Council and the National Academy of Sciences. In 2004, he was invited by the University of Chicago to be session leader and group facilitator on Materials science conference held in Doha, Qatar. He has served as a member of the SPE Education and Professionalism Technical Committee, SPE Student Chapter adviser, SPE Career Guidance and Student Development Committee, Technical reviewer, Committee Chairman/Member on the “SPE Distinguished Achievement Award for Petroleum Engineering Faculty,” Committee Chairman/Member on the “AIME Mineral Industry Education Award” and Member of Editorial Advisory Board of Offshore
Dr. Azar received the 1998 SPE Drilling Engineering Award and the 1997 SPE Distinguished Achievement Award for Petroleum Engineering Faculty. He was elected as SPE Distinguished Member for the year 2004. He was inducted into the U.S. National Academy of Engineering in Washington, D.C, in 2004. He is a registered professional engineer and a member of SPE. His areas of interest in teaching and research include: well bore fluids hydraulics, wellbore mechanics,drill bit mechanics, drill string mechanics, and well control mechanics in application to vertical, directional, horizontal, multilateral, coiled tubing, under-balanced, and slim hole drilling
Dr. G. Robello Samuel is a Senior Technical Advisor (Drilling) in the Drilling, Evaluation, and Digital Solutions division of Halliburton, where he has been since 1998. He has more than 18 years of experience in domestic and international oil/gas drilling and completion operations, management, consulting and teaching. His skills include well planning, design, cost estimates, supervision of drilling and completion operations, personnel and technical review, project management, and creative establishment of project relationships through partnering and
Innovation. Presently he is a technical and engineering lead for well planning engineering application suite for drilling, completions, and well services operations. Also he is an adjunct professor at the University of
Houston teaching advanced drilling and complex well architecture courses
He has authored or coauthored more than 50 conference and journal papers. He has given several graduate seminars at various universities. Dr. Samuel has been the recipient of numerous awards including the “CEO for A Day (Halliburton)” and “Top Gun (Drilling)” awards. He has also worked at Oil and Natural Gas Corporation, India from 1983 to 1992 as a drilling engineer. He is
Presently serving as a Review Chairman on the Society of Petroleum Engineers (SPE) Drilling and Completions Editorial Review Committee, American Society of Mechanical Engineers (ASME) Journal of Energy Resources Technology and as co-chairman of SPE Multilateral Technical Interest Group. His other professional experience includes being on the 2006–2008 drilling committee of SPE.
He holds BS and MS (Mechanical Engineering) degrees from University of Madurai, Madurai and College of Engineering Guindy, Anna University (Chennai), MS and PhD (Petroleum Engineering) degrees from the University of Tulsa. He is a member of ASME and SPE
His areas of research include wellbore fluids hydraulics, tubular design, thermal and flow phenomena and their effect on loading of wellbore tubulars, drilling and well cost optimization and downhole tool hydrodynamics
