Course goals and content:
1) Gain a qualitative understanding of seismic reflection acquisition and
processing, both industry and shallow.
2) Learn the seismic expression of major structural styles and stratigraphies.
3) Learn to operate current seismic interpretation software as commonly
used in petroleum industry.
4) Experience in writing and presentations.
Grading:
Homeworks, labs, two midterms, and a final project/presentation.
Homeworks and labs will be 40%; midterms 30%; and final project/presentation
30%.
I will expect higher quality work for graduate students, especially on the
final.
The course will cover the basics of reflection seismic interpretation with
emphasis on petroleum industry requirements. Some simplified seismic processing
will be also covered. Emphasis will be on structural interpretation more
than stratigraphic interpretation. We will use several computer-aided seismic
interpretation programs. We will begin with 2D seismic and then progress
to 3D and volume based interpretations and attribute analysis.
Required book
Fundamentals of Geophysical Interpretation by L. R. Lines and R. T. Newrick
($23 but need to join SEG - free for students)
Strongly recommended books
Applied Subsurface Geological Mapping by D. Tearpock and R. E. Bischke,
Perhaps a little dated, but thorough
Other books
I do suggest joining AAPG
and/or SEG as a student member if you are not already a member.
(job opportunities, resume padding, and maybe a scholarship or travel rebates).
Nominal schedule
- may vary and depends on status of licensed software and room availability
- powerpoints may contain only part of the day's topics
-we may have guest speakers.
