1. A method, comprising:
identifying a first formation top in a first well log of a plurality of well logs for a plurality of wells in a geographic region;
defining a first marker on the first well log based on the first formation top;
iteratively propagating the first marker automatically to a second well log of the plurality of well logs;
rendering a graphical user interface to a display, wherein the graphical user interface displays the second well log comprising a second marker that indicates a second formation top;
determining a confidence score for the second well log based on the second marker;
adjusting a visual indicator associated with the second marker based on the confidence score for the second well log; and
responsive to the adjusting, rendering the visual indicator associated with the second marker based on the confidence score.
