The objective of the Ferron Sandstone project was to develop a comprehensive, interdisciplinary, quantitative characterization of a fluvial-deltaic reservoir to allow realistic inter-well and reservoir-scale models to be developed for improved oil-field development in similar reservoirs world-wide. Quantitative geological and petrophysical information on the Cretaceous Ferron Sandstone in east-central Utah was collected. Both new and existing data were integrated into a three-dimensional model of spatial variations in porosity, storativity, and tensorial rock permeability at a scale appropriate for inter-well to regional-scale reservoir simulation. Simulation results could improve reservoir ...
The Mississippian Chainman Shale represents a potential target for untapped oil and gas resources in western Utah and eastern Nevada. This study focuses on the lithologic, facies, petrographic, petrophysical, and geochemical characteristics of a 500-meter-thick Chainman stratigraphic section exposed in the central Confusion Range of western Millard County, Utah. A hypothetical resources assessment, which can be used for the Chainman regionally, was conducted based on the surface samples' attributes from the study area. Hypothetical undiscovered hydrocarbons on 80-acre spacing are estimated at 270,000 barrels of oil and 1.5 billion cubic feet of gas per well. This CD contains a full report (30 pages, 24 figures, 3 tables, and 5 appendices which include the measured section, plates of geophysical logs, thin section photomicrographs, SEM images, etc.), in PDF format, of the description, analyses, and results from the Chainman Shale outcrop study and resource assessment. It also includes X-ray fluorescence, X-ray diffraction, and gamma-ray data and interpretations of the Chainman lithologies.
This report describes low-cost, innovative, non-invasive, surface geochmcial techniques for hydrocarbon exploration in the environmentally sensitive northern Paradox Basin of southeastern Utah. Exploration for Mississippian Leadville Limestone-hosted hydrocarbon reservoirs in the basin is high risk in terms of cost and low in documented success rate. However, the potential for more discovers and additional reservoirs is enormous. The main conclusion of the study is that certain surface geochemical methods can discriminate surface signatures between buried productive and non-productive Leadville reservoirs. 61 pages + 6 appendices
Greater Aneth oil field, Utah’s largest oil producer, has produced over 483 million barrels of oil. Located in the Paradox Basin of southeastern Utah, Greater Aneth is a stratigraphic trap producing from the Pennsylvanian Paradox Formation. Because Greater Aneth is a mature, major oil field in the western U.S., and has a large carbonate reservoir, it was selected to demonstrate combined enhanced oil recovery and carbon dioxide (CO2) storage. The Gothic shale seals the underlying Desert Creek oil reservoir, both in the Paradox Formation. Within the Aneth Unit in the northwestern part of the field, the Gothic is remarkably uniform, consisting of 7 to 26 feet (2–8 m) of black to gray, lamin...
The Cane Creek shale of the Pennsylvanian Paradox Formation has produced more than 7.8 million barrels of oil and about 7.9 billion cubic feet of gas from 18 fields in the Paradox Basin of southeastern Utah. The Cane Creek is divided into three intervals—A, B, and C; the B interval is the primary oil producer. Finely crystalline dolomites and sandstones in the B interval have been the main targets of successful horizontal drilling programs. Hydrocarbon shows were recognized using nondestructive epifluorescence (EF) microscope techniques on samples from wells in the northern part of the basin. A new, qualitative visual EF rating system was developed and applied to these samples. A variety o...
Utah’s landscape is among the most spectacular in the world. It is a region of prominent peaks, sweeping valleys, dramatic canyons, and plateaus rimmed by sheer cliffs. Unique among western states, Utah’s landscape includes the Colorado Plateau, Basin and Range, and Rocky Mountains geologic provinces. Exposed rocks tell the geologic story of the region’s basement structures, overlying surface features, and rock sequences that have contributed to sculpting the appearance of today's landscape. Rocks and formations record the evolution of the western part of the North American continent, and give clues to the nature of ancient crustal basement and Earth’s deeper layers. Climate change h...

Stars Above, Earth Below uses photographs and sky charts to form a connection between what is seen on the ground and in the sky, and looks at the deeper scientific meaning behind these sights. Nordgren describes other objects in the Solar System with features similar to those on Earth and links the geological features seen in the national parks to the very latest NASA spacecraft discoveries on other planets and their moons. Additionally, historical context is discussed to show why we humans (who have lived in and around our national parts for tens of thousands of years) have always been astronomers. The first book to make direct connections between astronomy and the landscapes, processes and cultures one experiences in the US National Parks Each chapter ties a specific astronomical phenomenon to a particular National Park or type of park and concludes with a “See for yourself” section that shows you how to see the planets, stars, nebulae, moons, etc. that are described within that chapter A personal guide showing the reader the astronomical phenomena that you can see for yourself when visiting the U.S. National Parks
