Rob Kirk, a 35-year career geologist, has researched "Onlaps" and lectured in seismic stratigraphy for the past decade. He shares some of his discoveries here.
Geological models are used to help with our geo-predictions up and down dip. We usually only have a few one-dimensional control points (wells) and a seismic grid to predict reservoirs, seals and source in our acreage. Seismic is often used only structurally, and if stratigraphy is contemplated, it is often via a few simplistic amplitude extractions.
