  • Field and modeling studies were performed to characterize two-phase flow within the natural cleat structure of an upper Cretaceous subbituminous coal seam. A two borehole pattern with open completion was used in a study of dewatering and tracer residence time distribution. Air was pumped into a five meter thick seam located about 170 meters below the surface. Krypton 85 was used as the airborne tracer. Air inflow and air and water production rates and tracer arrival times were monitored. The field tests were simulated with a two-phase, three component, porous flow code. Results showed that the air inflow and airmore » and water outflow rates and breakthrough times could not be modeled assuming a uniform darcy-type permeability. The use of a pressure dependent permeability did provide, however, a much better match with the field data.« less
  • Historic data from the Department of Energy Eastern Gas Shale Project (ESGP) were compiled to develop a database of geochemical analyses, well logs, lithological and natural fracture descriptions from oriented core, and reservoir parameters. The nine EGSP wells were located throughout the Appalachian Basin and intercepted the Marcellus Shale from depths of 750 meters (2500 ft) to 2500 meters (8200 ft). A primary goal of this research is to use these existing data to help construct a geologic framework model of the Marcellus Shale across the basin and link rock properties to gas productivity. In addition to the historic data,more » x-ray computerized tomography (CT) of entire cores with a voxel resolution of 240mm and optical microscopy to quantify mineral and organic volumes was performed. Porosity and permeability measurements in a high resolution, steady-state flow apparatus are also planned. Earth Vision software was utilized to display and perform volumetric calculations on individual wells, small areas with several horizontal wells, and on a regional basis. The results indicate that the lithologic character of the Marcellus Shale changes across the basin. Gas productivity appears to be influenced by the properties of the organic material and the mineral composition of the rock, local and regional structural features, the current state of in-situ stress, and lithologic controls on the geometry of induced fractures during stimulations. The recoverable gas volume from the Marcellus Shale is variable over the vertical stratigraphic section, as well as laterally across the basin. The results from this study are expected to help improve the assessment of the resource, and help optimize the recovery of natural gas.« less
  • The major problem plaguing the synfuels industry is the financing of large capital requirements in a technologically unproven field. This is exemplified by the 2 to 3 billion dollar investment required by oil shale development. Despite an unquestionable resource which is well characterized and a wealth of information from processes which have undergone extensive pilot development work, financing of a project is difficult because of the risk. In recent studies on a worldwide basis as a background for evaluating the Cottonwood Wash project in the Uinta Basin, Utah, the concept of small scale or modular development of this type ofmore » resource can lead to acceptable economics with a substantially higher probability of actual completion. This study discusses Uinta Basin oil shale resources and current developments and evaluates the economics of small scale or modular development for the Cottonwood Wash project processes. This evaluation shows the effects of such a development in reducing the project's economic and technical risks.« less
  • Comparison of several aspects of surface and underground methods of mining for large-scale oil shale extraction in the Piceance Creek Basin suggests that surface mining techniques may have several advantages over underground methods. For a production level of one million barrels of shale oil per day, potential advantages include those related to economics, environmental effects, and the overall national interest. One million barrels of shale oil per day could be produced from 2-3 large surface mines compared to perhaps 10-20 large underground mines. Fewer surface mines would result in: fewer roads and utility corridors, less acres disturbed per barrel ofmore » oil produced, reduced detrimental effects on ground water and surface water, less wildlife disturbance, a safer overall operation, a greater opportunity to achieve stable long-term land and water reclamation, potential economic advantages related to scale and materials handling, and a three- to five-fold increase in resource recovery. Advantages to underground (including modified in situ (MIS)) mines include: more flexibility of mine siting, mining and handling a minimum of waste rock, and simplified ore grade control for processing.« less
  • Three geothermal wells tapping the Dogger aquifer were studied in detail for their variations in chemical composition with time or conditions of exploitation. Analytical improvements for the determination of Cl, SO{sub 4}, Ca, Mg, Na and K make it possible to detect variations respectively of 0.15, 0.8, 0.6, 1.8, 1.8 and 1.4 %. Despite the fact that the natural flow may be important in some parts of the basin aquifer, we conclude that this factor is not responsible for the small variations noticed in mineralization within the one year survey period. The results concerning reactive and nonreactive species are bestmore » explained if a vertical heterogeneity of the chemistry of the fluid is assumed. A number of calcareous sub-layers, already demonstrated by geological studies, contribute to varying degrees to the production of the hot water. The changes in pumping rates, which are fixed according to external requirements, play a major role in the hydrodynamic and chemical disequilibrium of the wells. The consequences for the geothermal exploitations are emphasized.« less
