Exercise 3

             Build an SU Workflow

Build an SU script to do the following:

1) Read SEGY data into SU

2) Assume fldr is primary key (lines), and cdp is secondary key (traces)

3) fldr is numbered 811,813,…,1052, and cdp is numbered 2231,2233,…,2621

4) Re-sample the data to 8 milliseconds and save every line and CDPs 2231,2235,2239,… in your seismic directory for further processing. We have not talked about resampling, so you will have to find a re-sample tool to use.

5) Sort the data to cross-lines

6) Phase-rotate the data by plus 90

7) Display cross-line 2239. It should look like the display shown below.

Use the input data provided in /hou/data/D_152_001/SU_Class/class_project/seismic/tiger.sgy

Write output data to your seismic directory as tiger_cdp.su

Sample answer script is in

/hou/data/D_152_001/SU_Class/class_project/scripts/answers/exercise3.sh
