2.1 Introduction Chapter 2 Geothermal ResourceBase Assessment 23 Table 2.1 Geothermal resource categories. Previous analyses have suggested that the amount of thermal energy available for Enhanced Geothermal System (EGS) development is enormous (Armstead and Tester, 1987; Rowley, 1982; Mock et al., 1997; Tester et al., 1994; Sass, 1993). However, these earlier works did not use detailed geologic information – and, as a result, the methodologies employed and resulting resource estimates were, by necessity, somewhat simplified. This study utilizes published geologic and geophysical data for the United States to calculate the stored thermal energy (or “heat in place”) on both a national and state level, at depths from 3 to 10 km. The methodology, resource types considered, and the resource base calculations are included in this chapter. Recoverability, or useful energy, is discussed in Chapter 3 of this report. A depth of 3 km was selected as a cutoff for upper depth because, outside of the periphery of active magmatic and hydrothermal systems, temperatures in excess of 150°C at less than that depth are rare. Category of Resource Reference Conductiondominated EGS Sedimentary EGS This study, basins > 4 km Basement EGS This study Volcano Geothermal Systems USGS Circular 790 + new data Hydrothermal USGS Circulars 726 and 790 Coproduced fluids McKenna et al. (2005) Geopressured systems USGS Circulars 726 and 790 Several classes of geothermal resources are discussed in this chapter (Table 2.1). In earlier analyses – USGS Circular 726 (White and Williams, 1975), USGS Circular 790 (Muffler and Guffanti, 1979), and USGS Circular 1249 (Duffield and Sass, 2003) – the geothermal resource was divided into four major categories: hydrothermal, geopressured, magma, and conductiondominated (Enhanced Geothermal Systems or Hot Dry Rock). The resource classes that are discussed in this report include 1) sedimentary Enhanced Geothermal Systems (EGS), 2) basement EGS, 3) geopressuredgeothermal systems, and 4) coproduced fluids (hot aqueous fluids that are produced during oil and gas production). Brief mention is also made of supercritical/volcano (i.e., igneous) geothermal systems. There is overlap of some of these categories, which will be explained in the discussion that follows. Conventional hydrothermal resources, presumed to exist at depths of 3 km or less, are specifically excluded. A team at the United States Geological Survey (USGS) (Williams, 2005) is currently reevaluating these resources. Also not included, because of their relatively small geographic size, are EGS resources on the periphery of hydrothermal systems in the Western United States. While these types of resources are certainly of high grade and can be viewed as nearterm targets of opportunity, they are so small in area and sitespecific that a regional study of this scale cannot quantitatively assess them. They are, in general, extensions of the hydrothermal resource and will be identified as part ofPDF Image | Geothermal Resource Base Assessment
