Seismic Reflection Processing Workshop, June 7-8, 2005

Hosted at University of Portland, sponsored by IRIS

Intended audience

Undergraduates and graduate students at IRIS institutions having a basic grasp of the common-midpoint reflection seismic method, possibly from a previous lecture course or from first-hand experience.


Course instructor

Roger Young, Oklahoma University


Course description

This is an interactive, computer-based, 2-day course of instruction in fundamentals of seismic reflection processing. It was designed to extend the understanding of principles taught by lectures in an introductory college course in seismic exploration.


Course objective

To come to an understanding, through a hands-on processing experience, of the consequences of model simplifications and mathematical assumptions imposed on the real earth during the processing of seismic data. Students will receive a copy of the EAGE book, A Lab Manual of Seismic Processing, and an attached CD-ROM, which includes all short course notes, the complete SPW processing software package keyed to the seismic data set, the seismic data set, and all intermediate processing results generated during the short course.


Course outline

Instruction consists of a sequence of 12 labs:

Lab 1 Reformatting seismic data; assigning geometry to seismic trace headers
Lab 2 Trace gathering
Lab 3 Velocity analysis: making semblance maps
Lab 4 Comparing semblance maps
Lab 5 Picking a semblance map; picking reflection events
Lab 6 Normal moveout correction; stacking CMP gathers
Lab 7 Editing: killing and muting traces
Lab 8 Testing and applying statistical deconvolution; bandpass filtering
Lab 9 Residual statics correction
Lab 10 Residual statics correction/velocity analysis iteration
Lab 11 Final stack
Lab 12 Post-stack time migration

Application process

One undergraduate and one graduate student from IRIS member institutions may apply to attend the course. Food and lodging will be provided as part of the course and up to $500 will be reimbursed for air travel. A limited number of positions are available.

To apply, please fill out and fax the Member Representative form AND send an email to Cathy Snelson with the following information:

Name
Academic institution
Email
Academic Year (undergrad) or degree program (MS or PhD)
Brief (less than 100 words) description of why you want to attend the workshop

Applications must be approved by the IRIS institutional Member Representative and will be considered on a first-come, first-served basis. Graduate students are encouraged to also apply for a scholarship to attend the IRIS/UNAVCO workshop IRIS/UNAVCO workshop to be held at Skamania Lodge on June 9-11.

Applications are due by April 11 but note that the IRIS/UNAVCO workshop scholarship deadline is April 4.

For more information about registering for the workshop, please contact Cathy Snelson.
