The information system, SIPS, is designed to handle and transfer data relating to subsurface geology. The data are of 2 types: geologic research materials available in the Subsurface Laboratory, and information concerned with the documented research relating to subsurface geology.

Methodology of the information system involves formulation of the system, specification of the theoretical framework, search for relevant techniques to implement the formulation, and defining the procedure.

The system is designed to transfer the information by selective retrieval specified by the subsurface geologist, whether stratigrapher, sedimentary petrologist, or petroleum geologist. The geologist is provided with a list of pertinent material in a specified location within designated stratigraphic and depth intervals that correlate with the search criteria. Relevant research documents are retrieved selectively to provide bibliographic and abstract listings through a variety of search options based on concept formulation and descriptor indices.
