D. R. Griffin & Associates Mapping

DRG provides a wide variety of Oil & Gas maps for the intermountain region.  Maps range from large area maps to topographic maps containing: gas well locations, resource roads, pipelines (and some utilities), environmental data and significant landmarks.  DRG maps are continually updated with field surveys which are used to maintain the CAD database.  The database includes more than 20,000 DRG projects, information from operators and government agencies which are then applied to the various maps.  Updated maps prove useful in transportation planning and to all those involved in the exploration, development and maintenance of the various gas fields.
