Deepwater turbidite system analysis, West Africa: Sedimentary model and implications for reservoir model construction

The complex sedimentary architecture of various offshore turbidite systems within the Tertiary formations of Gulf of Guinea, offshore West Africa, can be explained by using 3D seismic interpretation to define sedimentary and stratigraphically units which then become input for reservoir models and simulations. The geologic model is composed of sedimentary units of different scales whose width, thickness and lateral continuity, composition, facies partitions, and lateral/vertical succession are determined from analysis of 3D seismic and well data.

Seismic image segmentation by fuzzy fusion of attributes

To know the subsoil organization, geophysicists try to interpret seismic images acquired by sending acoustic waves into the soil. This paper presents a method for the segmentation of these images in geological regions in order to help interpreters in their study. Information fusion of image attributes provides a solution to part of this complex problem. To realize aggregation, the fuzzy subset theory is an appropriate tool to code interpreter knowledge by a set of rules. The results obtained are promising and show the necessity to evaluate their quality more thoroughly.
