Depth 2D/3D Processing
Through a strategic alliance with 3DGEO (www.3dgeo.com), Arcis has access to a full suite of depth imaging tools that augment Arcis' proprietary depth migration algorithms.
Pre stack depth migration
- Migration velocity toolbox; the right tools for the right complexity:
- Offset gathers & angle gathers
- Automatic & manual residual velocity picking
- Vertical, Normal Ray and Tomographic raytracing updating
- Internet collaboration and QC
- Velocity model building:
- Near surface model imported from tomographic GLI
- Initial velocity model imported from:
- PSTM velocities converted to depth
- Well information
- Client input
- Fast target Kirchhoff scheme allows natural output of gathers for finely sampled velocity analysis
- 3D MVA provides automated or manual picking of semblance analysis with optional horizon tracking, supported by interactive graphical aids to high-grade results
- Full range of velocity updating: vertical, normal ray, or tomographic
- Flexible grid model concept, supported by horizon-based options, where appropriate
- Versatile tools and 3D visualization capability for interpreter involvement, including real-time Internet-based collaboration environment
