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.
This paper analyzes the evolution of giant meandering submarine channels in the Campos Basin, Brazil, and their interaction with salt diapirs.
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 paper explores the development of counter point bars in meandering rivers through autogenic translation processes.
The simplest definition of point bars is that they are sedimentary deposits forming on the inner, convex bank of river bends. [‘Inner’ and ‘convex’ bank means that, looking toward the river, the bank is curving around you.] Amadeus W. Grabau, an early ‘influencer’ in stratigraphy and sedimentary geology, published a beautiful drawing of how meanders grow, point bars evolve, and oxbow lakes form, more than a hundred years ago: Diagram illustrating the development of meanders in a river. From Grabau (1920). ...
