Because of the high precision of present-day GPS and reflectorless laser technology, geologic information and remotely sensed data (i.e., seismic and GPR grids, wells) can be positioned accurately in 3-D and reconstructed as a virtual image. Hence, we have developed the “virtual outcrop” for applications that require knowledge about the 3-D spatial arrangements of rock types.

This article shows how we have applied digital methodology to geologic reconnaissance and in detailed outcrop mapping, including characterization of an outcrop as a reservoir analog where we merged detailed outcrop mapping with geophysical GPR survey data, wells, and stratigraphic sections.

Mapping is the...
