Stochastic Dynamic Time Warping for Automated Stratigraphic Correlation

摘要

Systems and methods for stochastic correlation of stratigraphic data in a subsurface formation include: receiving data representing stratigraphy of the subsurface formation at a plurality of locations; generating a cumulative distance matrix of the data representing the stratigraphy of the subsurface at a first location of the plurality of locations and the data representing the stratigraphy of the subsurface at a second location of the plurality of locations; obtaining, by traversing the cumulative distance matrix according to a series of deterministic steps and intermittent stochastic steps, a minimal cost path over the cumulative distance matrix; and defining, based on the performing, one or more correlations of the stratigraphy of the subsurface formation at the first location and the stratigraphy of the subsurface formation at the second location; and
