Space & AirAlgorithm design for exploration geology
The main goal of exploration geophysics is to map the variations in the
properties of rocks in the subsurface (that are interpreted through the magnitude and time of arrival
of reflections measured at the surface) to reveal the earth features. These
informations are crucial in many fields: they can be used to find oil and gas
traps, to study waste-disposal sites, for archaeological investigation.
All these applications show the need for a detailed description of the subsurface,
that can be achieved only by carefully handling the amplitudes of recorded seismic data.
However, during the acquisition stage, obstructions, cable feathering, economic constraints and many other factors cause seismic data to be sampled in sparse and irregular fashion. This introduces noise/artifacts that can limit the resolution of the final image.
The ability of focusing on both algorithmic accuracy and the effect of sparse and irregular sampling of the wavefield plays a key role in developing highly customized solutions to specific seismic data processing tasks.
ARESYS ability to design specific and highly customized algorithms spans all the steps of standard processing sequence, from noise reduction algorithms to anisotropic imaging techniques, for both surface acquisitions geometries (marine or land) and VSP datasets.
Following ARESYS main topics of interest, customized solutions have been derived for:
