Unconventional petroleum systems are becoming much more important world wide in oil and gas exploration and development. These reservoirs are low porosity and permeability but contain enormous amounts of resources. Unconventional reservoirs include the following: tight oil and gas, CBM (coal bed methane), gas shales, and heavy oil or bituminous sands. This field trip is designed to examine several of these unconventional systems in the outcrop.
This two-day field trip will be along the Front Range of Colorado on the western flank of the Denver Basin and in the Florence-Canon City basin area. We will examine examples of tight-oil reservoirs (Cretaceous Niobrara Formation, Codell member of Carlile Formation), heavy oil/tar sands (Cretaceous J Sandstone), and tight-gas reservoirs (Cretaceous J Sandstone, Codell).
