Full Survey Description
Poseidon 3D seismic survey is located on the Australian NW shelf, in the Browse basin. The subsurface data is made available by GEOScience Australia under the terms of the Creative Commons licence Attribution 3.0 Australia (CC BY 3.0 AU). ConocoPhillips shared this data via GoogleDrive along with a deep learning seismic facies clustering tool called MalenoV.
dGB Earth Sciences loaded 3D seismic (full/near/mid/far stacks) and well data (deviation surveys only) into OpendTect project. The following modifications were made by dGB Earth Sciences:
1) well data was imported into OpendTect format (original files can be found in RawData folder of the project directory).
2) full stack was converted to CBVS format and compressed to 8 bit with scalar=127/45000=0.00282.
3) near/mid/far angle stacks were converted to CBVS format and compressed to 8 bit with scalar=0.0015.
NOTE: the main download includes only full stack seismic and well tracks. Additional downloads section includes the angle stacks in 8-bit CBVS format, original 32-bit SEGY files, and well data (logs, VSP, etc.).
