Surface smoothing within an earth model of a geological volume of interest

摘要

Surfaces may be smoothed within an earth model of a geological volume of interest. More specifically, smoothing may be done on a specific surface by smoothing or otherwise altering dip values without changing the position of the surface within the earth model. Dip values may determine certain behaviors of a surface such as reflection and refraction of seismic energy propagating within the earth model.

1. A system for processing an earth model of a geological volume of interest, the system comprising:
one or more processors configured to execute computer program modules, the computer program modules comprising:
an earth model module for obtaining the earth model of the geological volume of interest, wherein the earth model includes a polygon mesh that describes a position of a surface within the geological volume of interest, the polygon mesh being comprised of planar polygons defined by three or more vertices, and the earth model including positional coordinates for the vertices of the polygons;a dip module for determining values of the dip of the polygon mesh within the earth model, wherein determining values of the dip of the polygon mesh includes determining values of dip for the individual polygons based on the positional coordinates of the vertices defining the polygons;a smoothing module configured to smooth the values of dip along the polygon mesh without impacting the positional coordinates for the vertices of the polygons.
