The company, which provides technology, project management and information services to the global oil and gas industry, said that the services allow petrotechnical experts to improve the reliability and consistency of seismic structural and quantitative interpretation in complex environments.

Maurice Nessim, president of Schlumberger PetroTechnical Services, said, “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.

“With Depth Domain Inversion Services, customers receive more information derived from seismic data for reservoir characterisation. This helps reduce uncertainty in complex reservoir environments, improve the confidence in prospect delineation, reservoir properties and volumetric calculations.”

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 added.

This is done by correcting for depth space and dip dependent illumination effects during seismic amplitude inversion directly in the depth domain.
