Unlocking seismic amplitudes for facies prediction using seismic petrophysics –  A Goliat case study

Honore Yenwongfai

Abstract

 “The profit margins for oil and gas companies are narrowing down as the exploitation costs increase while the oil and gas prices decrease. As a result, it becomes even more important to employ quantitative seismic characterization schemes in order to reduce both the financial and operational risks. Lithology and fluid prediction from all available data is the ultimate goal for subsurface hydrocarbon exploration. Reservoir drainage in field development is also dependent on this information.

The Goliat Field is the first oil field to be in production in the Norwegian sector of the Barents shelf. In this case study the focus is on the prediction of lithology and fluid from seismic and well log data, and how this can be extended to effective porosity and shale volume predictions. Finally seismic driven conceptual geological models are inferred using integrated AVO, rock physics, and seismic inversion derived products.”

Biography

Honore Yenwongfai has a MSc degree from 2011 at Department of Geosciences, University of Oslo. He then worked in Statoil until he last year returned to the University of Oslo to do a PhD within a large research project focusing on the Triassic in the SW Barents Sea. In his PhD study the main focus is on seismic inversion, seismic attributes and facies analysis using rock physics and petrophysical techniques as a basis for improved reservoir characterization and fluid prediction.
