Grid or 3D data acquisition enables data coverage between the receiver lines. In addition, all receivers in the grid are active while the source is being towed, which allows data to be recorded for a multiple of narrow to wide azimuth angles.
The benefits of 3D EM include:
- Increased data coverage and density from wide azimuth acquisition geometry.
- Improved delineation of reservoirs, and higher confidence in smaller magnitude anomalies.
- Minimised risk of missing your target.
- Provides a dataset suitable for full 3D inversion, which allows for better integration with other subsurface data.
- Improved resolution - spatially and in depth.
- Provides more information on anisotropy.
- Enchanced integration into the exploration and production workflow.
