Hydrothermal eruptions, like geysers, are intriguing phenomena; they are spectacular while in motion and generally unwarming while not. Their non smooth nature makes for difficulty in both conceptual and mathematical modeling. In this paper, an attempt is
This study discussed the application of algorithms developed in Operations Research to the optimization of brine reinjection in geothermal fields. The injection optimization problem is broken into two sub problems: (1) choosing a configuration of injector
The geothermal resources in Tianjin is belongs to the typical low-medium geothermal resource in sedimentary basin. The geothermal distribution area is 8700 km2..about 77% of the total Tianjin area. As a clean energy, the geothermal resourced is widely use
The geothermal prospects (geothermal fields) beneath the Beijing Plains Area are associated with unique (paleo-) basement aquifers of high permeability. The main aquifer appears to be coherent beneath the whole Beijing Graben where it can be found typical
Present geothermal power cycle for low enthalpy geothermal fields (utilizing brine not steam) attain electrical efficiencies far from the ideal carnot factor and therefore are not well utilizing the expensive geothermal wells. This is to a large part due
This resource is a compilation of thermal conductivity observation data for unconsolidated sediment and bedrock from Geothermal Test Wells in Maryland provided by the Maryland Geological Survey. Data are available in the following formats: web feature service, web map service, ESRI service endpoint, and an Excel workbook for download. The workbook contains 5 worksheets, including information about the template, notes related to revisions of the template, resource provider information, the data, a field list (data mapping view) and a worksheet with vocabularies (data valid terms) used to populate the data worksheet. This resource was provided by the Maryland Geological Survey and made available for distribution through the National Geothermal Data System. The data schema has been revised and this version is deprecated.

1:24,000 scale Geologic Map of the Gass Peak Quadrangle, Clark County, Nevada. Nevada Bureau of Mines and Geology Map 175. Detailed geologic mapping by Alan R. Ramelli, William R. Page, Craig R. Manker, and Kathleen B. Springer in 2001. Map includes description of 30 geologic units. The GIS work was in support of the U. S. Geological Survey COGEOMAP program. The Geodatabase specifies feature datasets and feature classes, together with feature attributes, subtypes and domains, suitable for the printed geologic map. In addition to basic geology (lithology, contacts and faults, etc.), the maps may include metamorphic overprints, cross-sections, and explanatory legend-graphics such as correlation charts, used to supplement columnar legends. Includes results of geochemical analyses and age determinations of igneous rocks. Both the map and GIS Work are available for purchase at the links provided under online availability.

The Digital Raster Graphic (DRG) is a raster image of a scanned USGS topographic map including the collar information, georeferenced to the UTM grid.A DRG is useful as a source or background layer in a GIS, as a means to perform quality assurance on other digital products, and as a source for the collection and revision of DLG data. DRG's can also be merged with other digital data, e.g. DEM's or DOQ's, to produce a hybrid digital file. To download this resource, please see the link provided.
