Shallow-Shelf Carbonate Buildups in the Paradox Basin, Utah—Targets for Increased Oil and Gas Production and Reserves Using Horizontal Drilling Techniques (B-140) Little Cottonwood The Navajo and Kayenta aquifersCompiled and edited by Thomas C. Chidsey, Jr., 173 p., 11 appendices Summary: The Pennsylvanian Paradox Formation is the major producer of oil and gas in the Paradox Basin of southeastern Utah and southwestern Colorado. The Paradox Formation was deposited in a warm, shallow shelf marine environment and contains a wide variety of carbonate lithofacies. Traps are stratigraphic formed by carbonate buildups consisting principally of phylloid algal
