【 摘 要 】

The six coal fired power plants located in the Colorado Plateau and southern Rocky Mountain region of the U.S. produce 100 million tons of CO{sub 2} per year. Thick sequences of colocated sedimentary rocks represent potential sites for sequestration of the CO{sub 2}. Field and laboratory investigations of naturally occurring CO{sub 2}-reservoirs are being conducted to determine the characteristics of potential seal and reservoir units and the extent of the interactions that occur between the host rocks and the CO{sub 2} charged fluids. The results are being incorporated into a series of two-dimensional numerical models that represent the major chemical and physical processes induced by injection. During reporting period covered here (July 1 to September 30, 2003), the main achievements were: Preparation for Project Review visit in Salt Lake City by new Project Manager; Submittal of two scientific papers to a special issue of ''Chemical Geology'' on CO{sub 2} sequestration; Set-up of website reporting results of this project; and Publication of summary article in Utah Geological Survey ''Survey Notes'' (circulation of 3000).
