Quantitative tools for seismic stratigraphy and lithology characterization
Seismological images represent maps of the earth’s structure. Apparent bandwidth limitation of seismic data prevents successful estimation of transition sharpness by the multiscale wavelet transform. We discuss the application of two recently developed techniques for (non-linear) singularity analysis designed for bandwidth limited data, such as imaged seismic reflectivity. The first method is a...
متن کاملFractional Spline Matching Pursuit: a quantitative tool for seismic stratigraphy
A matching pursuit algorithm is used to obtain quantitative information on the litho-stratigraphical content of seismic data. The method is based on a greedy non-linear algorithm decomposing the data into atoms drawn from a redundant dictionary defined by fractional splines. The atom’s parametrization provides localized scale, order and direction attributes which carry information on the strati...
متن کاملLaser-Derived, Particle Size Data from CRP-2/2A: Implications for Sequence and Seismic Stratigraphy
Gravel-free, high-resolution (1-metre spacing, 32 channel) particle size data from the CRP-2/2A drill core indicate that many of the diamictites were likely deposited from floating ice. Textural dislocations occur at most sequence boundaries and provide independent corroboration of the sequence stratigraphic interpretation. Likewise the data largely support the correlation drawn (Fielding et al...
متن کاملSeismic stratigraphy of the Bill Bailey and Lousy Bank area: implications for subsidence history
The present study discusses some results of a reconnaissance seismic survey carried out in 1988 in the area around the prominent Bill Bailey and Lousy Banks, located SW of the Faeroe Islands. The area is thought to be part of the Rockall-Faeroe microcontinent, which was flooded by Palaeocene plateau basalts. The seafloor topography is largely due to the present-day organization of the basalt su...
متن کاملConstrained Seismic Sequence Stratigraphy of Asmari - Kajhdumi interval with well-log Data
Sequence stratigraphy is a key step in interpretation of the seismic reflection data. It was originally developed by seismic specialists, and then the usage of high-resolution well logs and core data was taken into consideration in its implementation. The current paper aims in performing sequence stratigraphy using three-dimensional seismic data, well logs (gamma ray, sonic, porosity, density, ...
