Course Overview: This one-day course presents more than a dozen case studies of bypassed or unconventional pay in shale, clastics, and carbonates. The examples will be reviewed by class attendees in teams and discussed with the class in a workshop format designed to encourage discussion and learning. With no equations beyond the Archie formula, and minimal theory, the goals of the course are;
- To improve skills in recognizing unusual log signatures that can indicate an unconventional or bypassed resource.
- To provide basic logging tool theory.
- To improve skills in quality control of standard logs and processed logs. 
- To recognize situations where additional help may be needed, and where additional logs, core or other information might be needed for proper formation evaluation.

Recommended For: For general audiences from new grads to gray hairs, for all Geoscientists – anyone with a basic understanding of logs. A diverse mix of experience levels and disciplines provides better discussion.

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.  Day five will be a computing lab to include processing of NMR data sets using Logic 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 40 NMR short courses to over 725 participants, and has published 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.
