Abstract
Summary
During a seismic interpretation exercise, picking an unconformity is one of the most time-consuming and ambiguous tasks. In this paper we present a method to quickly detect areas that are highly likely to be an unconformity, using the principle that at angular unconformities the azimuth and dip of the strata changes. We introduce a workflow to classify what kind of unconformity has been detected, by feeding the areas with high unconformity probabilities into a convolutional neural network. This adds the benefit that one can quickly discern whether the region was associated with significant uplift or not.
