“Conventional seismic inversion in the time domain introduces inconsistency between the seismic images and the rock properties, especially where there’s a significant overburden, such as subsalt,” says Maurice Nessim, president, Schlumberger PetroTechnical Services.
Performing seismic inversion in the depth domain fully integrates the inversion with the imaging products to improve the reliability of estimating rock properties for reservoir characterization, the company says.
