  Required textbooks
for Lecture (Liner) and Lab (Forel et al.)

Course Book: Liner 3rd Edition

Elements of 3-D seismology by Chris L. Liner, 2004, 608 pp. Second Edition (Table of Contents)

Seismic Data Processing with Seismic Un*x 2007 Forel, D. Benz, T. and Pennington, W. 2007, 16 capters, SEG, OK.

Goals:

Introduction to 2D and 3D seismic data acquisition, processing and limitations of seismic interpretation in the context of deep (0-10 km) and near-surface (0-100m) seismology.

Course work

Weekly homework, a field-based seismic processing project, one midterm and one final in-class exam.

Lectures  will be dedicated to the presentation of concepts covered by the course textbook and Labs will be dedicated to exercises using academic and industrial seismic processing software in the Subsurface Laboratory (E217).  Lab work will include processing of an original data set.  All homeworks and lab exercises, with the exception of the final project, are due one week after they are handed out, at the beginning of each class. 

Recommended prior courses or experience Math I, II, Physics-I, programming experience with a high-level language like Excel,Matlab or Maple, etc. Web navigation
 

Course Grades

Final letter grades are calculated using the results of weekly lecture homework and in-lab exercises (30%), a midterm exam (15%), a final  lab project (55%).  A (90-100%) , B (80-89.5%), C (60-79.5%) D (50-59.5%), F (less than 49.5%) Graduate students taking this course will be held to a higher standard, commensurate with their academic seniority.
