This course covers surface substitution, mapping anisotropic data, mapping unconformities, faulting, integrating well and seismic data, and volumetrics. An overview lecture introduces each topic, followed by in-depth exercises designed to reinforce the practical points of the lesson. GeoAtlas™ software, ZoneManager WellBase™ software, XSection™ software and Query Builder™ software also are used in conjunction with IsoMap® software to provide students with different methodologies used in surface modeling.

After this course, students should be able to: (1) manually edit contours and create a new grid from them; (2) handle edge effects, clustered and linear data, and gridding artifacts to achieve a more geologically reasonable map; (3) handle multiple depositional environments and geometries in a single map surface; (4) create and modify fault polygons and build faulted surfaces; (5) map unconformity surfaces and subcrop isopachs; (6) use different velocity methods to convert a time surface to a depth surface; (7) model complex geometries for creating a volumetric grid; (8) define volumetric polygons and calculate volumetric quantities; and (9) view multiple surface geometries and renderings in 3-D.
