Abstract

Abstract: Here, we show a novel use of a mathematical technique in stratigraphic visualization, which has been effectively used in other fields, to generate high-resolution strata texture maps to improve the rendering of two-dimensional forward stratigraphic simulations during post-processing. The texture maps are obtained by convolving stratigraphic timelines with a random dotted pattern that produces realistic layerings similar to those observed in seismic cross sections. The texture mappings are scale-independent and are not affected by artifacts like moiré patterns. Thus, the stratigraphy in poorly resolved areas is rendered at the same level of detail as those zones with high numerical resolution. The texture maps can also be combined with other attributes generated by numerical simulations like sedimentation rate or grain size to bring into the foreground subtle details that otherwise could be swamped by large amplitude or high frequency stratigraphic signals. Highlights: Method to improve visualization of stratal patterns during post-processing. Convolution of timelines with dotted pattern improves stratigraphic resolution. Moiré and other undesirable patterns are eliminated. Method gives computer outputs a more natural appearance.
