Stefan Z. Miska is currently Jonathan Detwiler Endowed Chair Professor of Petroleum Engineering and Director of Tulsa University Drilling Research Projects (TUDRP) at The University of Tulsa (TU). He obtained his M.S. and Ph.D. degrees from the University of Mining and Metallurgy in Cracow, Poland. Over the years, he has taught at his Alma Mater, at the Norwegian Institute of Technology and New Mexico Tech. In 1992 he joined TU as Chair of its P.E. Department. Miska published over 160 technical papers and contributed to several books. His current research interests are focused on wellbore hydraulics, mechanics of tubulars and directional drilling. He is involved with the SPE in many ways; he has served as Technical Editor for Drilling and Completion and is a member of the Drilling and Completion Advisory Committee. He was also the recipient of the 2000 Distinguished Petroleum Engineering Faculty, 2003 Outstanding Technical Editor and the 2004 Drilling Engineering awards. Miska also serves on the JPT Editorial Committee.
Robert F. Mitchell is a Halliburton Fellow in the Drilling and Evaluation Division of Halliburton. Previously, he was vice president of Enertech Engineering and Research Company from 1980 to 1996 and worked at Exxon Production Research Co from 1973 to 1980. Mitchell has published more than 80 papers on wellbore and well completion problems. He edited the Drilling Engineering volume of SPE’s 2007 Petroleum Engineering Handbook and is currently lead editor for the SPE textbook Fundamentals of Drilling Engineering. He has served as a technical editor for several peer-reviewed journals and is currently Executive Editor of SPE Drilling & Completion. Mitchell holds BA, MME, and PhD degrees from Rice University. He was the recipient of the 2005 SPE Drilling Engineering Award.
Michael L. Payne is a senior advisor for BP in the Exploration and Production Technology Group (EPTG) in Houston. Previously an advisor for Arco, Payne has 29 years of drilling experience, including operations, computing, technology, and consulting; he has worked in the areas of ERD, HP/HT, deepwater well design, tubulars, drilling dynamics, failure analyses, reliability, and special projects. Payne has published extensively and has served as Chairman of several API and ISO committees. He holds BS and PhD degrees in mechanical engineering from Rice University, an MS degree in petroleum engineering from the University of Houston, and executive education from Southern Methodist University and the University of Chicago GSB. Payne has been recognized by SPE as a Distinguished Lecturer (1995) and with the Drilling Engineering Award (2000).
