Stratigraphic correlation of geophysical well logs is one of the most importantand most time-consuming—tasks that applied geoscientists perform on a daily basis. Using the dynamic time warping (DTW) a…
In this talk, I first want to revisit and visualize the basic ideas about how time is recorded - or not recorded - in sedimentary deposits and then show how chronostratigraphic diagrams can be used as key elements of an automated workflow for correlating geophysical well logs.
Interpretation of deep-water channel deposits is challenging because the spatial arrangement of their constituent lithologies is highly variable. This variability is often thought to be a signature of…
We use experimental data from the ‘Jurassic Tank‘ flume (St. Anthony Falls Laboratory) to create three-dimensional chronostratigraphic diagrams, compute stratigraphic completeness, and test several sequence stratigraphic concepts.
This presentation explores the dynamics of meandering systems in both fluvial and submarine environments, focusing on the predictability of channel migration and the resulting stratigraphic heterogeneities.
We investigate the relationship between the cross-sectional geomorphic expression of a submarine channel as observed on the seafloor and the stratigraphic product of long-lived erosion, bypass, and se…
