Course Book: Liner 3rd Edition

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

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

Bi-weekly homework, lab homeworks, a field-based seismic processing project (Visual communication skills), two midterm  exams.  Two of the lab homeworks will be used to emphasize technological communication skill sets.

Lectures  will be dedicated to the presentation of concepts covered by the course textbook and Labs will be dedicated to exercises using academic seismic processing software in the Subsurface Laboratory (E217).  Lab work will include processing of an unpublished seismic data set collected by LSU students and faculty .  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, Mathematica, etc. Web navigation.
 

Course Grades

Final letter grades are calculated using the results of weekly lecture homework and lab exercises and homeworks (30%),one midterm exam ( total of 20%), two technological communication projects (25%) a visual communication project  (25%).  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.

This course is certified as a �Communication-Intensive Course� and meets all of the requirements explained on the CxC Web site: http://cxc.lsu.edu., including the following: Emphasis on formal and informal assignments in written and visual communication, class time spent on communication, 40% of the final grade based on communication projects, revisions after faculty feedback on 2 formal projects (one for each emphasis), and a student/faculty ratio of 35:1. Because it meets these requirements, students may count it toward �Distinguished Communicator� certification on LSU transcripts.

Communication Intensive Assignments

VISUAL EMPHASIS
(written minor component)
TECHNOLOGICAL EMPHASIS

Informal Activities

Students will sketch conceptual models to describe physical processes attending wave propagation During lab sessions, students will complete lab assignments modifying existing programs to answer achieve specific goals established in the handout of the day.

Formal Activities

Students will develop visual explanations to justify the use of different seismic algorithms and show using resultant seimsic images the results of applying different parameters. A general flow chart is required to explain the overall goals of the project. A complete visual processing sequence  is required in the explanations of all of the processing stages. Students will develop software (using Perl and Seismic Unix) that will render best results at each processing stage for seismic data.  Each student will develop two existing seismic processing modules with a perl wrapper.  Each resultatnt module will be fully documented using in Perl documentation language.  Examples of each working module will also be provided by each student. 

Feedback

Draft-review-revise process will be implemented for developing an electronic document that includes generation of images to represent best-practices in the choice of processing parameters. Computer Code (from technological project) can also be included.
Each laboratory exercise (bandpass filtering and beyond) will form part of the overall Visual  Project.
Draft-review-revise process will be implemented on each of the two modules targeted for development, and which will require students to program as well as generate technical documents.
