Automated multi-well stratigraphic correlation and model building using relative geologic time

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…

Channel trajectories control deep-water stratigraphic architecture

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…

Point bars and counter point bars: Why is sediment deposited on the 'wrong' side of a meander bend?

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). ...

Evaluating the relationship between meander‐bend curvature, sediment supply, and migration rates

River meander migration plays a key role in the unsteady ‘conveyor belt’ of sediment redistribution from source to sink areas. The ubiquity of river meandering is evident from remotely sensed imagery,…
