Borehole Seismic Data Processing
ODP logging contractor: LDEO-BRG
Location: Great Australian Bight (SW Pacific Ocean)
Latitude: 33° 30.5613' S
Longitude: 128° 3.9844' E
Logging date: October, 1998
Water depth (as seen on logs): 795 mbrf
Total penetration: 463.3 mbsf
Total core recovered: 40.5 m (12.9 %)
TOOL USED: WST (Well Seismic Tool).
The logging data was recorded by Schlumberger in DLIS format. All processing, including first arrival picking and stacking, was performed by Schlumberger during Leg 182. The data was then converted into SEGY format at the Borehole Research Group of the Lamont-Doherty Earth Observatory, using the SEGY Save module in GeoFrame.
Stacks are generally calculated with at least seven good traces.
All the data in the SEGY files are sorted shot by shot (i.e. chronologically).
