Unlike all conventional sim-source techniques and methods based on compressive sensing, where a sub-set of sources are fired at intervals of several 100ms or even seconds, all the source elements in both Source Isolation and Source Revolution fire within a few tens of milliseconds of each other; this gives natively full-fold data. Apparition also results in data that is completely isolated directly after acquisition whilst on-crew QC can be carried out on the pre-isolated data with confidence.
- No mid-record interference on pre-stack data
- Pre-Isolation field data show impact of weather or similar interference, optimizing operations
- Isolated data are full-fold for improved AVO, demultiple and other value-adding pre-stack applications
- Isolated data are suitable for 4D applications, thus eliminating the conflict between cost and quality
