Course Overview; This is a comprehensive summary of NMR Logging including basic physics, signal processing, practical considerations and tool selection, job design, data processing, interpretation, quality control and log / core integration. Emphasis is on practical application and building of interpretation skills. The course features plenty of real-world examples including tremendous NMR success stories and failures. Day five will be a computer lab featuring processing of NMR data sets using Logic and Petcom software.

Brian Stambaugh is President of NMR Petrophysics, Inc., a petrophysical consultancy in Houston. After nine years with Schlumberger, he joined Numar Corporation in 1990. While at Numar, Brian assisted with development of new computational techniques specific to NMR data, and assisted with marketing and engineering efforts as borehole NMR technology emerged. He also served as technical and marketing consultant to Computalog, Atlas Wireline and Halliburton Logging Services, and provided interpretation and technical support during assignments in Canada and Indonesia. Brian has performed or supervised the petrophysical analysis of NMR data sets from over 1500 wells, has delivered 38 NMR short courses to over 650 participants, and has published several articles and technical papers on the subject of NMR logging. In addition to teaching he performs petrophysical field studies, and consultation regarding NMR logging. He has served as an SPWLA Distinguished Lecturer and SPE Technology Update Speaker. Brian holds a B. S. M. E. from South Dakota School of Mines and Technology.

I have attended this seminar and found it to be a thorough examination of NMR by a very knowledgeable analyst. Excellent." - Petrophysicist with 30 yrs experience

"Your balanced approach was most refreshing. The manual will be quite useful as an ongoing reference guide." - Petrophysicist

"This was a very good course that I would highly recommend to others. The manual was excellent and it will be a valued reference book". - Engineer

"I feel better able to judge now in which situations an NMR log would be justified." - Geologist

Other Courses Available:

NMR Logging: Data Acquisition, Interpretation and Job Planning Workshop:  This is a two day NMR logging short course designed to provide Engineers, Geologists, Managers and Petrophysicists with a complete working knowledge of NMR Logging. The course will provide an overview of tool technology, theory of operation and interpretation techniques, with a focus on practical applications and getting used to working with NMR data. Job planning and an assessment of CMR and MRIL strengths are also covered. Most of the log examples are analyzed by students in hands-on work sessions. Attendees are provided with a detailed course manual (200+ pages) with extensive color log examples. A job planning spreadsheet will be distributed, and its use will be demonstrated. Students are invited to bring their own NMR log examples for review and discussion, as well as laptop PC’s on the second day to run the spreadsheet during this part of the course. The first day will be an overview of tool theory, data processing, comparison of tool designs, and basic interpretation techniques. The second day will focus on direct fluid characterization, job planning, log-core integration, and additional interpretation examples.  These schools have been attended by Halliburton, Baker Atlas, Computalog, Vastar, Enron, Amoco, Exxon, Burlington, Chevron, UP Resources, Coastal, Exxon, Pennzenergy, Marathon, Enterprise, AGIP, Swift Energy, Cobb and Associates, Mobil, Husky, Mitchell Energy and many others.
