The Raton Basin is the southernmost classical Laramide basin in the Rocky Mountain region and straddles the New Mexico-Colorado state line. As an asymmetric basin, deeper to the west, its central portion lies at the western end of Las Animas County, Colorado. Over 1900 bottom-hole temperatures (BHTs) were compiled from the logs of 1886 wells in Las Animas County, most of which were drilled over the past fifteen years, and are associated with the extraction of coalbed methane, primarily from Upper Cretaceous and
Paleocene formations. Most of the wells from which the BHT data were collected... More →

Imagine this. The year is 2030 A.D. Renewable energy sources are supplying over 50% of the United States' energy needs. Total energy use has decreased dramatically from its exorbitant 1990's level. Multi-megawatt windfarms, solar thermal farms and biomass plants dot the landscape. Biofuels and solar-derived hydrogen make many of our cars, trains and buses go. Photovoltaic energy technology is converting sunlight directly into electricity in remote locations. Hydropower continues to provide electricity using such technology as run-of-the-river facilities which don't need huge dams. High-tempera... More →

Using this assessment approach, an approximation of geothermal production can be made, using a simple block model analysis. Estimated
production values are used to derive the economic viability given current market conditions. The economic analysis includes consideration of geothermal binary heat exchange systems and existing infrastructure, and determines the lowest projected cost of development for particular reservoirs in the Hidalgo County region.

Published online: 14 August 2008

Geothermal exploration is typically limited to high-grade hydrothermal reservoirs that are usually found in the western United States, yet large areas with subsurface temperatures above 150C at economic drilling depths can be found east of the Rocky Mountains. The object of this paper is to present new heat flow data and to evaluate the geothermal potential of Texas and adjacent areas. The new data show that, west of the Ouachita Thrust Belt, the heat flow values are lower than east of the fa... More →

Five separate NGDS projects provide the data support, acquisition, and access to cyber infrastructure necessary to reduce cost and risk of the nation's geothermal energy strategy and US DOE program goals focused on the production and utilization of geothermal energy. The U.S DOE Office of Energy Efficiency and Renewable Energy Geothermal Technologies Program is developing the knowledge and data foundation necessary for discovery and development of large-scale energy production while the Buildings Technology Program is focused on other practical applications such as direct use and residential/c...

A Texas resource assessment study documents a large untapped heat resource within deep sedimentary basins. Long considered a liability by the oil and gas industry and uninvestigated by the geothermal industry, this sleeping heat energy giant boasts many thousands of exajoules waiting for electrical power production. Subsurface temperature-depth (t-d) recordings from O&G log headers provide minimum temperatures found underground. Temperatures from 250 (121) to over 400F (204C) occur at varying depths and in different geographical areas. Presently five large areas are defined that have stron... More →

Map services are also being developed for isopach maps, aquifer temperature maps, and several states are working on geothermal resource overview maps. Content models are developed preferentially from existing community use in order to encourage widespread adoption and promulgate minimum metadata quality standards. Geoscience data and maps from NGDS participating institutions (USGS, Southern Methodist University, Boise State University Geothermal Data Coalition) are being supplemented with extensive land management and land use resources from the Western Regional Partnership (15 federal agencie...

Geopressured geothermal reservoirs are characterized by high temperatures and high pressures with correspondingly large quantities of dissolved methane. Due to these characteristics, the reservoirs provide two sources of energy: (1) chemical energy from the recovered methane and (2) thermal energy from the recovered fluid at temperatures high enough to operate a binary power plant for electricity production. Formations with the greatest potential for recoverable energy are located in the gulf coastal region of Texas and Louisiana where significantly overpressured and hot formations are abundan... More →

This paper is to provide an introduction of present technologies and current R&D efforts and opportunities in order to provide a starting point for additional monitoring of exploration and drilling technology progress. The research and development opportunities in geothermal exploration and drilling technologies are many as evidenced by the recent DOE ARRA awards. Future R&D should continue to focus on evolutionary improvements to conventional technolo... More →

The ability to translate the geothermal potential of sedimentary basins into productive use lies in the application of basic science and engineering research. Effective use also lies in reducing the economic risk of geothermal exploration and development which inhibits attracting financial investors to this energy sector. In addition, it is also important to provide federal and state decision makers and agencies with the information they require to make sound decisions about geothermal energy. Thus, the long-term vision is to integrate NSF-sponsored research, education and cyber infrastructure... More →

One of the most interesting aspects of this shallow thermal model will be its applicability to geothermal energy exploration in the future. A new understanding of thermal behavior in the shallow crust may enable the pursuit of creative and revolutionary new clean, safe and ubiquitous energy reserves for global consumption.

Chapter 21 - Geothermal Energy
Geothermal (meaning “earth heat”) energy involves using the high temperatures produced beneath the earth to generate electricity from heated water, as well as for various direct uses (such as hot springs spas, lumber drying or aquaculture). The term geothermal is also applied to the temperatures of the Earth near the surface which are used as a source of consistent temperatures for heating and cooling of buildings. Geothermal applications that involve water heated within the earth are also called hydrothermal processes. While geothermal energy is... More →

The President's National Energy Policy (2001) jump started the U.S Geothermal Resource program by authorizing the Secretaries of the Interior and Energy to increase access to public lands for geothermal energy production. To meet this goal BLM worked with the Department of Energy's National Renewable Energy Laboratory (NREL) to produce the report “Opportunities for Near-Term Geothermal Development on Public Lands in the Western United States” that identified 35 top-pick sites for geothermal development. In 2004, BLM completed a geothermal strategic plan which is guiding the agency ... More →
