NMR Logging Technology
|Event Date/Time: Feb 28, 2011||End Date/Time: Mar 04, 2011|
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 more than 40 case studies and log examples.
Day five will be a computing lab to include processing of NMR data sets using Logic software.
A complete set of course materials and a light lunch are included.
*Participants will need to bring a PC laptop to each day of this course*
