ABSTRACT
Breccia associated with sediment-filled cavities is relatively common throughout the upper third of the Mississippian Leadville Limestone in Lisbon and other fields, Paradox Basin, southeastern Utah. These cavities or cracks are related to karstification of the Leadville during exposure in Late Mississippian time. Infilling of the cavities by detrital carbonate and siliciclastic sediments occurred before deposition of the Pennsylvanian Molas Formation. The transported material consists of poorly sorted detrital quartz grains, chert fragments, and clasts of carbonate and clay. The carbonate muds infilling the karst cavities are very finely crystalline and non-porous dolomites.

ABSTRACT
Greater Aneth oil field, Utah’s largest oil producer, was discovered in 1956 and has produced over 451 million barrels (bbls) of oil. Located in the Paradox Basin of southeastern Utah, Greater Aneth is a stratigraphic trap producing from the Pennsylvanian Paradox Formation. Because it represents an archetype oil field of the western U.S., Greater Aneth was selected to demonstrate combined enhanced oil recovery (EOR) and carbon dioxide (CO2 ) sequestration. The Aneth Unit in the northwestern part of the field has produced 149 million bbls of the estimated 450 million bbls of OOIP—a 33% recovery rate. The large amount of remaining oil made the Aneth Unit ideal to demonstrate both CO2 storage capacity and EOR by CO2 flooding.
GEOLOGIC MAP OF THE WHITE HOUSE QUADRANGLE, GRAND COUNTY, UTAH
Hellmut H. Doelling and Paul Kuehne
The White House quadrangle is located northeast of Arches National Park in eastern Utah. Exposed strata range from Late Jurassic Brushy Basin Member of the Morrison Formation to Late Cretaceous Mancos Shale. The quadrangle overlies the ancestral Paradox basin and is influenced by salt-related folds, including the Salt Valley anticline to the west and Cisco Dome to the east.
