How Statoil uses gOcad to improve Deep Marine Deposition recognition from seismic data

in: 18th gOcad Meeting, ASGA

Abstract

In this talk, we will focus on three aspects that allow us to better understand deep marine deposits from seismic data and to review these technics and show how and when we want to apply them. Deep marine deposits represent good reservoir opportunities, however, complexity is a major limiting factor in resolving its geometry. Improvement in seismic acquisition and processing has opened new windows for geologists to have better quality data, however, new technologies are also necessary to take advantage of this potential. Statoil has been putting effort into such new interpretive technics: •.First, we start with outcrop modeling. We collect as much 3D information as possible on the geometries and depositional environments. These 3D computer models serve to transfer the “picture in the mind” to other “brains”. •Secondly, these models are used to run seismic finite difference simulation. The model and the seismic sections are compared directly. •Lastly, on real subsurface data, we propose to look at seismic attributes using horizon slices instead of the classic time slices. Slicing along the bedding planes allows one to detect possible geologic features. Such technics are even more powerful when the horizon slices stay within a stratigraphic or channel interval.
