John H. Cohen has worked in research and development in the oil industry since his graduation from the Colorado School Mines in Golden, Colorado. His degree in Mineral Engineering Physics has given him a unique view and allowed him to work on a variety of different projects over the past 41 years. Mr. Cohen has significant experience in developing and improving down-hole tools including; roller cone and PDC drill bits, turbo drills, mud motors, turbine generators, MWD tools, rig instrumentation, and rotary steerable tools.
He has also worked on subsea equipment including; riser design, collet connectors, and subsea pumping systems. Mr. Cohen was director of The Drilling Research Center, where he developed methods and apparatus for testing oil field equipment, down-hole tools and drilling concepts. Included among these was the testing of fluids for a unique method of dual gradient drilling.
This interest in new technology and dual gradient drilling continues today with work on subsea pumps and concepts for dual gradient and riserless drilling. Based on his work in developing new equipment Mr. Cohen has authored many papers, and holds several patents. He is former Chairman of the IADC Dual Gradient Drilling Subcommittee, where he works to encourage the development of this new technology.
John Morten graduated with a MSc in 1992 and a PhD in 1997, both from the Department of Engineering Cybernetics at the Norwegian University of Science and Technology (NTNU). From 1997 to 2001 he held a position as a project engineer at Kongsberg Seatex, before he joined Statoil as a principal researcher in Trondheim, Norway. Since August 2013, he has worked as an expat in Statoil’s office in Houston. He also holds a position as an Adjunct Professor in Drilling Automation at the Dept. of Petroleum Engineering and Applied Geophysics, NTNU, Norway.
