Practical Wireline Formation Testing and Sampling
Mohamed Hashem is currently the subsurface technology manager for the North Caspian Operating
Company, seconded from Shell. Previously he was Shell’s regional technology manager for the Middle East, Caspian, and South East Asia. Mohamed is also Shell’s principal technical expert for formation testing and sampling. This is the highest technical level achievable in Shell short of a chief scientist. Mohamed earned his BSME degree from Ain-Shams University in Cairo, Egypt in 1980; an MSPE degree from the University of Southern California in Los Angeles in 1987; and a DE degree in 1990 in petroleum engineering from Stanford University. Mohamed joined Shell in 1990, and worked on shelf and deepwater Gulf of Mexico exploration, development and production projects including Shell’s flagship Auger project (1st deepwater project). For the last 12 years, Mohamed worked on global Shell projects as a Global Consultant. Before 1990, he worked for Schlumberger and was lecturer at the University of Southern California in Los Angeles. Based in Astana, Mohamed is currently working on bringing new technology to develop the challenging Kashagan field and its satellites. Throughout his career, he has worked on major projects in the Far and Middle East, Europe, Africa, Australia and the Americas. Mohamed is the author of 13 patents and numerous publications and papers. He was SPE Distinguished Lecturer in 2009/2010, and SPWLA Distinguished Lecturer from 2003 to 2007.
