Announcement: In-Depth Optimized CS Survey Conversion now available in TesserACT and MESA
In-Depth's optimized CS Survey design uses our patented MC-map survey evaluation tool to minimize local mutual coherence throughout your entire survey. In other words, our technology determines how much information is actually lost in a particular area when removing sources and receivers from a survey, ensuring your data can be properly reconstructed after acquisition.
Our CS Survey Design takes into account the presence of obstacles, clustering points around large holes to minimize the aliasing of spatial frequencies (and maximize reconstructibility) in missing data regions while adhering to your chosen survey design grid.
How it works:
First, you provide a conventional grid survey design. Your initial design should take into account your target and any expected geological features. Your final acquired data after reconstruction will look as if it were acquired by this conventional input design.
Second, input any obstacle information. Our MC-map solver takes into account the position of obstacles in advance, arranging source and receiver points to ensure that the data can be properly reconstructed in those regions.
Next, run the In-Depth CS Survey Conversion. This will remove 20% of the sources and/or receivers from your conventional grid survey, using Compressive Sensing principles to ensure all of the data can be properly reconstructed.
Finally, use the 2D MC-map evaluation tool to make sure that the CS survey design has a low mutual coherence throughout the survey. If the number of shots or receivers you have available for your survey is fixed, consider starting with a denser conventional grid so that the number of shots and receivers is correct after decimation. This will give you the highest spatial resolution/fold possible given your particular survey constraints.
