Palynological Mapping of Vertical Microseepage over Dragoon and Pollen Fields

Peter K. H. Groth

Fossil pollen was recovered from multiple shallow boreholes in Colorado's D-J basin. Detailed light transmissibility of a particular pollen species was obtained, and the data were contoured. Extensions to Dragoon and Byers fields were mapped, and new fields Pollen and Quill were mapped and predicted. The patented technique recognizes mineral oxidation surrounding reduced or reduction-maintained areas of microseepage above reservoirs that are present at a depth of 7,500 ft.
