Offshore seismic data has its own set of problems; multiples, ghosting and imaging of complex structure including salt bodies are just a few examples.

- A robust tau-p deghosting algorithm is an important part of the Geomage solution, allowing for consistent broadband marine data.
- Multiples can be attacked with a powerful radon demultiple, or advanced SRME approach, adaptive subtraction can be coupled with multiple modelling technologies to remove difficult to differentiate multiples from the data.
- In the MultiFocusing process multiples can be analyzed, identified and eliminated across multiple wavefront parameters, allowing for a clear separation of primary and multiple in the MF enhanced data.
- In the presence of complex structure or salt, MultiFocusing not only improves the imaging, but can provide detailed data driven velocity information helping identify geologic boundaries in the data.
- At later stage the technology derived velocity model gives better migration imaging in the time domain, as well as more accurate data based velocity models in the depth domain.
