Quantitative analysis of the economically recoverable resource

The objective of this study is to obtain estimates of the economically recoverable gas in the Appalachian Basin. The estimates were obtained in terms of a probability distribution, which quantifies the inherent uncertainty associated with estimates where geologic and production uncertainties prevail. It is established that well productivity on a county and regional basis is lognormally distributed, and the total recoverable gas is Normally distributed. The expected (mean), total economically re… more

Comparison of laboratory, in situ, and rock mass measurements of the hydraulic conductivity of metamorphic rock at the Savannah River Plant near Aiken, South Carolina

In situ testing of exploratory wells in metamorphic rock indicates that two types of fracturing occur in the rock mass. Rock containing small openings that permit only extremely slow movement of water is termed virtually impermeable rock. Rock containing openings of sufficient size to permit transmission of water at a significantly faster rate is termed hydraulically transmissive rock. Laboratory methods are unsuitable for measuring hydraulic conductivity in hydraulically transmissive rock; how… more

Rock Matrix and Fracture Analysis of Flow in Western Tight Gas Sands: Annual Report, Phase 3

Tight gas sands are a vast future source of natural gas. These sands are characterized as having very low porosity and permeability. The main resource development problem is efficiently extracting the gas from the reservoir. Future production depends on a combination of gas price and technological advances. Gas production can be enhanced by fracturing. Studies have shown that many aspects of fracture design and gas production are influenced by properties of the rock matrix. Computer models for … more

Solution chemistry and scaling in hot dry rock geothermal systems

Field and laboratory experiments have focused on measuring the kinetics and equilibria associated with the transport of minerals from granite to circulating aqueous solutions. Presently two wellbores drilled to a depth of approximately 10,000 ft in the Valles Caldera region of the New Mexico Jemez mountains permit closed-loop circulation of fluid through a hydraulically fractured granite geothermal reservoir containing rock at 200/sup 0/C. Field measurements have dealth primarily with the build… more

Waste disposal by hydrofracture and application of the technology to the management of hazardous wastes

A unique disposal method, involving hydrofracturing, has been used for management of liquid low-level radioactive wastes at Oak Ridge National Laboratory (ORNL). Wastes are mixed with cement and other solids and injected along bedding plane fractures into highly impermeable shale at a depth of 300 m forming a grout sheet. The process has operated successfully for 20 years and may be applicable to disposal of hazardous wastes. The cement grout represents the primary barrier for immobilization of… more

Hot dry rock heat mining: An alternative energy progress report

Mining Heat from the hot dry rock (HDR) resource that lies beneath the earth's crust may provide an almost inexhaustible supply of energy for mankind with minimal environmental effects. In the heat mining process, water is pumped down an injection well into a mass of hydraulically fractured hot rock. As the water flows under high pressure through the opened rock joints, it becomes heated by the rock. It is returned to the surface through a production well (or wells) located some distance from t… more

Subsurface disposal of liquid low-level radioactive wastes at Oak Ridge, Tennessee

At Oak Ridge National Laboratory (ORNL) subsurface injection has been used to dispose of low-level liquid nuclear waste for the last two decades. The process consists of mixing liquid waste with cement and other additives to form a slurry that is injected under pressure through a cased well into a low-permeability shale at a depth of 300 m (1000 ft). The slurry spreads from the injection well along bedding plane fractures and forms solid grout sheets of up to 200 m (660 ft) in radius. Using thi… more
