Cross Sections, Data Projection and Dip-Domain Mapping

Abstract

A cross section shows the relationships between different horizons and allows the information from multiple map horizons to be incorporated into the interpretation. Cross sections may categorized as illustrative or predictive. The purpose of an illustrative cross section is to illustrate the cross section view of an already-completed map or 3-D interpretation. A slice through a 3-D interpretation is a perfect example. The purpose of a predictive cross section is to assemble scattered information and, utilizing appropriate rules, predict the geometry between control points. A predictive cross section can be used to predict the geometry of a horizon for which little or no information is available.
