Stranded Oil in the Residual Oil Zone
An analysis by Advanced Resources International, Arlington, VA, and Melzer Consulting, Midland, Texas, for the U.S. Department of Energy's Office of Fossil Energy
Five reports on Stranded Oil in the Residual Oil Zone (ROZ) introduce one of
the most exciting new, unconventional oil resources that can be added to our
domestic oil resource base. This is "stranded (or residual) oil" in the transition zone
below the traditional oil-water contact that exists in many domestic oil reservoirs. This resource has not previously been included in any official domestic oil resource databases. Work was undertaken in three U.S. oil basins ? the Permian, Williston and Big Horn -- to more rigorously define the size and potential of this new resource, and how much may be recoverable using CO2-EOR techniques.
