Course Project for fall 2003

Valle Central de Chile

Today we will see a typical brute stack flow applied to LSU Line 04 from the Livingston area at the Puchi site:

NAME of sub-flow

Purpose
viewSEGY_1.82.gl Display SEGY data for quality control
seg2sfam_182.gl Convert SEGY data to OmegaSPS internal format
viewSfam_182.gl Display OmegaSPS data set
trdelrev_182.gl Delete and reverse polarity of traces
TraceHdrMth_182.gl Changes station numbers for detectors (geophones) in the trace headers
SPXY2Hdr_182.gl Transfer shotpoint locations (UTM, Z=15) from an editable text file to the trace headers in the seismic data set
DtectXY2Hdr182.gl Transfer geophone locations (UTM, Z=15) to the trace headers in the seismic data set
Cre8Frstgdb_182.gl Create an initial geometry data base
mkCDPInGDB_182.gl Create CDP geometry information in the data base and pass it on to the seismic data headers
TraceMth_SrcDtct_Dist_182.gl Create the shot-geophone (source_to_detector_distance) in the headers of the seismic data by mathematical manipulation
viewCMP_182.gl Check to see if the CMP's look all right
VelGenerator_182.gl Create a velocity file
brutestack_182.gl Generate the first pass stack by sorting the data in CMP's then applying a hyperbolic NMO, filter, gain and summation.

As you process your own data set for your course project you can start by using the above flows.  Then you can branch out and try new options in the flow. For example you may want to change the velocity structure, apply an f-k filter, test different bin sizes in your CMP geometry.  (The image with the most usable geological information wins!)
