SEMINAR OUTLINE:  SEISMIC PETROPHYSICS

"50 Years Of Continuous Petrophysical Experience, At Your Service"

 

COURSE SUMMARY
This semi-quantitative course covers topics needed to calculate log response in support of seismic modeling, creation of synthetic seismograms, and synthetic seismic sections. Editing and repair of sonic and density logs (log modeling) and creation of velocity and density logs from other log data is stressed.

 

Fluid and rock replacement concepts, as well as uses of compressional and shear acoustic logs to calibrate inversion, AVO, and porosity/lithology analysis from seismic attributes wraps up the subject.

 

You can't use a well log for geophysical purposes unless it is corrected for invasion and bad hole effects. Find out how to do it here.

COURSE DURATION
1 day - 8 Professional Development Hours (PDH)

COURSE LEVEL
Beginner to Intermediate, calculator required.
