Kirchhoff Prestack Depth and Time Migration
The most widely used migration algorithm in the industry
Accommodate a range of geological settings and acquisition geometries with flexible, amplitude-preserving implementation.
Philippines Sulu Sea & East Palawan Basin
Reprocessed multiclient 2D seismic data
Newly reprocessed multiclient 2D seismic data from the Philippines Sulu Sea and East Palawan Basin are now available. The reprocessing project was conducted in association with MultiClient Geophysical (MCG).
The data coverage and quality are appropriate for
- establishing a regional geologic framework
- identifying, mapping, and predicting source, reservoir, and seal of various plays
- evaluating prospectivity
- optimizing exploration work programs.
2D data reprocessed in association with MCG.
Reprocessed 2D data sample highlighting transpression, drapeover, and inversion anticlinal traps as well as a fault-bounded trap and base postrift.
Steps included in the reprocessing workflow
- Noise attenuation
- 2D surface-related multiple elimination (SRME)
- Radon demultiple
- Postradon isolating multiple algorithm (PRIMAL)
- Isotropic Kirchhoff prestack time migration (PSTM)
- Postmigration radon demultiple
- Dense spatially continuous velocity analysis (SCVA)
- Mute and final stack
