French-hub collaborates to get the most out of existing seismic data

Estimages and Eliis are pleased to announce the release of a new filtering solution for seismic data combining high-resolution interpretation and advanced geostatistical filtering: the Interpretative Filtering (IF) solution.

Geoscientists already acknowledge the power of oriented filters to clean-up seismic data by enhancing coherent events and reducing random noise, but the combination of fine scale interpretation and non-stationary geostatistical filtering now opens the way to improved filtering of seismic volumes, even in complex structural environments.

The Interpretative Filtering solution is based on a 3D non-stationary factorial kriging technique, known as M-GS® factorial kriging, guided by geological structures. The cutting-edge interpretation software PaleoScan™ produces a Relative Geological Time model that allow the generation of an unlimited number of horizons. Those iso-age surfaces, which enable a very high-resolution stratal slicing of seismic volumes, are incorporated in the geostatistical process.

IF gives remarkable results for removing random and organized noise from seismic volumes. This new generation of spatial filters delivers volumes free of noise, especially in structurally complex areas. Structural interpretation on the filtered volume remains unchanged, but signal quality is dramatically improved, as well as any work or attributes relying on it.

In the current challenging environment for the oil and gas industry, this optimized solution ensured that all the information contained in the seismic data is fully utilized without recourse to additional data collection.

Beyond the Interpretative Filtering Solution, Estimages and Eliis could also in the future combine their unique complementary capability for 4D co-filtering studies and creation of refined velocity models.
