CWLS19SC Unconventional (By-Passed) Pay
This half-day course presents more than a dozen case studies of unconventional or bypassed 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 improve skills in quality-control of standard logs and processed logs.
- To recognize situations 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.

Since 1997, Brian Stambaugh has been president of NMR Petrophysics, Inc., a petrophysical consulting firm in Houston, Texas. Previously Brian was with Schlumberger as a field Engineer, and Numar where he assisted in operations, processing, and interpretation efforts as NMR technology emerged. His experience with NMR has included data sets from over 1500 wells. He has given short courses to more than 800 students on NMR operations, interpretation, and data processing and provides technical assistance for oil companies and for oil service companies. He has served as an SPWLA Distinguished Lecturer and SPE Technology Transfer Speaker. Brian holds a BSME from South Dakota School of Mines and Technology.
