Abstract

In accordance with the present invention, a system and a method for generating structural, stratigraphic and petro-physical interpretations of geophysical and geological data to produce sub-surface geologic maps, cross-sections, and models, are disclosed that provide additional advantages over and/or substantially reduce disadvantages associated with the previous methods of seismic data interpretation. The method for interpreting seismic data includes a touch screen based computer system that is easily operable to collect coordinate and other attribute data associated with seismic and well log information. The system is capable of giving the user a feel of virtual paper-pencil based interpretation by allowing the user to freely draw interpretations and annotations on the seismic and well log displays, and collecting all such annotation and interpretation data are stored as a set of points. The system also collects the structural, stratigraphic and petro-physical information and stores in the database.
