Reflection Seismology

Geology 4068 

Fall 2012

Dr. Juan M. Lorenzo
Department of Geology and Geophysics

Lecture and ...	Tuesday and Thursday E207 7.30-8.30 a.m. 1+ Saturday field day (voluntary)
Lab times	2.00 p.m. - 5.00 p.m. Thursdays E217 Subsurface Lab
Office hours	Tuesdays and Thursdays by appointment For appointments and all correspondence e-mail: gllore@lsu.edu Subject:  GEOL4068
Textbooks for Lecture-required (Liner) and Lab-recommended (Forel et al.)	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 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	Bi-weekly homework, lab homeworks, a field-based seismic processing project (Visual communication skills), one midterm and one final in-class exam.  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 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, Mathematica, etc. Web navigation.
Course Grades Field Trip	Final letter grades are calculated using the results of weekly lecture homework and lab exercises and homeworks (30%), a midterm exam (20%), the best of two technological communication project (15%) a visual communication project (Wikipedia) (35%).  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. (Voluntary) This year we will conduct a shallow seismic survey on the vicinity of the Bayou Corne sinkhole (Assumption Parish, LA) and further analyze the data we collect during laboratory sessions
Tentative	Lectures by industry geophysicist:  XX This semester we will have:  XXX
COLOR CODES	In Powerpoint (GREEN) format, in MSWord (BLUE) format and as old html files, .
Program Downloads	Matlab programs for lectures ---> SEA  (self-expanding archive)
Resources:	Matrix Multiplication in Matlab; Matlab tutorial Computational Toos for Geoscientists Notes (LSU) Processing 102205 LSU line06 landstreamer data (LSU)
	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.  From among the complete processing sequence visual explanations of one of the processing stages will be published to a Wikipage.

Students will develop software (using perl and Seismic Unix) that will render best results at each processing stage for seismic data.  From among the complete processing sequence one of the programs will be published to a Wikipage.

Feedback

Draft-review-revise process will be implemented for developing a wiki page that include generation of images to represent best-practices in the choice of processing parameters. Computer Code (from technolgical project) will also be included.,

Draft-review-revise process will be implemented on two of the 6 required problem sets that require students to program in perl and Seismic Unix for signal processing of seismic data.
