sub-pixel channel boundary delineation based on partial area effect

Considering buried channels as prevalent stratigraphic traps is indispensable in petroleum exploration and drilling. this article presents a novel seismic attribute that employs the partial area effect strategy to detect individual discontinuities, especially channel boundaries. we tested the recommended method on a simulated time slice with meandering and branching sinusoidal channels of different sinuosity and thickness and on field data sets from southwest iran. we evaluated the effectiveness of the partial area effect algorithm against well-known edge detectors and seismic attributes. the results revealed that the designated algorithm could produce a more accurate map of channel boundaries with reduced influence from random noise. quantitative validation tests, including localization error, precision, sensitivity, and error rate, likewise confirmed the superiority of the proposed sub-pixel procedure.
