Topographic and Air-Photo Lineaments in Various Locations Related to Geothermal Exploration in Colorado

These line shapefiles trace apparent topographic and air-photo lineaments in various counties in Colorado. It was made in order to identify possible fault and fracture systems that might be conduits for geothermal fluids, as part of a DOE reconnaissance geothermal exploration program.

Geothermal fluids commonly utilize fault and fractures in competent rocks as conduits for fluid flow. Geothermal exploration involves finding areas of high near-surface temperature gradients, along with a suitable "plumbing system" that can provide the necessary permeability. Geothermal power plants can sometimes be built where temperature and flow rates are high.

This line shapefile is an attempt to use desktop GIS to delineate possible faults and fracture orientations and locations in highly prospective areas prior to an initial site visit. Geochemical sampling and geologic mapping could then be centered around these possible faults and fractures.

To do this, georeferenced topographic maps and aerial photographs were utilized in an existing GIS, using ESRI ArcMap 10.0 software. The USA_Topo_Maps and World_Imagery  map layers were chosen from the GIS Server at  server.arcgisonline.com, using a UTM Zone 13 NAD27 projection. This line shapefile was then constructed over that which appeared to be through-going structural lineaments in both the aerial photographs and topographic layers, taking care to avoid manmade features such as roads, fence lines, and utility right-of-ways.  Still, it is unknown what actual features these lineaments, if they exist, represent.

Although the shapefiles are arranged by county, not all areas within any county have been examined for lineaments. Work was focused on either satellite thermal infrared anomalies, known hot springs or wells, or other evidence of geothermal systems. Finally, lineaments may be displaced somewhat from their actual location, due to such factors as shadow effects with low sun angles in the aerial photographs.

Credits:
These lineament shapefile was created by Geothermal Development Associates, as part of a geothermal geologic reconnaissance performed by Flint Geothermal, LLC, of Denver Colorado.

Use Limitation:
These shapefiles were constructed as an aid to geothermal exploration in preparation for a site visit for field checking. We make no claims as to the existence of the lineaments, their location, orientation, and/or nature.

Memos Relating to High-Priority Geothermal Targets in Colorado Selected for Further Study - Flint Geothermal 2012

This dataset contains several memos describing geothermal targets outlined by Flint personnel in Colorado. Phase 1 involved an ASTER and LANDSAT thermal infrared imagery assessment conducted by CIRES of the University of Colorado, which identified areas of warm ground that might indicate geothermal heating. CIRES used the thermal ground anomalies, together with other GIS layers, to come up with a set of areas ("polygons") having high geothermal potential. 

This was followed by a "ground truthing" or site assessment by Geothermal Development Associates of Reno Nevada, during the summer and fall of 2011. Of the many areas targeted and visited, several stood out for their overall geothermal potential.

In the first memo, "Colorado Targets", GDA's Richard "Rick" Zehner describes the geothermal geology of the following properties, which were deemed to have the highest geothermal potential:
1. Routt (aka Strawberry Park) Hot Springs in Routt County;
2. Rico area, Delores County;
3. Pagosa Springs, Archuleta County;
4. San Luis Valley, Alamosa and Conejos Counties;
5. Lemon Hot Springs, San Miguel County

The second memo, "Comments on Rick's Report", from CIRES investigators, is a critical evaluation of Zehner's memo, in relation to CIRES' satellite thermal anomaly maps.

The third memo, "Penrose Area" is a detailed description of preliminary investigations into the geothermal potential of that area in Fremont County.

Spatial Analysis of CIRES ASTER and LANDSAT thermal infrared anomalies

CIRES provided polygon shapefiles showing areas of anomalously warm ground, derived from ASTER and LANDSAT remotely sensed thermal infrared imagery. Partly from these anomalies, and partly through other evidence layers, CIRES came up with 'polygons' representing areas prospective for geothermal development. Many of the anomalies are much larger and of different shapes than typical geothermal outflow zones, and many occur on ridgetops or other places geothermal systems typically do not form. This might indicate that the thermal anomalies are mostly solar (not geothermal) in nature.

The purpose of this analysis is to construct some spatial statistics to help understand the viability of the CIRES target model. In this model, ground thermal anomalies in Colorado are detected using either ASTER or LANDSAT thermal infrared spectral bands (among others). Those areas above some anomaly threshold (1 and 2 standard deviations) were then designated as "anomalous." One way to test the viability of their model would be to examine the area spatial statistics make use of the relative area of anomaly versus the total area, and the relative proportion of overlap between ASTER and LANDSAT data. If the area considered to be anomalous is large compared to the total area, then the infrared imagery would be a "blunt tool" for finding geothermal systems: the search is confined to too large an area. If there is disagreement between the areas found to be anomalous by ASTER and the areas found to be anomalous by LANDSAT, then the technique might not be robust. 

To do this, ESRI Spatial Analyst was used to convert all of the anomaly shapefiles into ESRI grids with a 100m cell size. The the total area of the target polygons as well as the areas of ASTER and LANDSAT anomaly were calculated. Finally, the area of overlap between the ASTER and LANDSAT anomalies in a given polygon area was calculated.

Penrose Well Temperatures

Penrose Well Temperatures

Geothermal waters have been encountered in several wells near Penrose in Fremont County, Colorado. Most of the wells were drilled for oil and gas exploration and, in a few cases, production.

This ESRI point shapefile utilizes data from 95 wells in and around the Penrose area provided by the Colorado Oil and Gas Conservation Commission (COGCC) database at   http://cogcc.state.co.us/ . Temperature data from the database were used to calculate a temperature gradient for each well. This information was then used to estimate temperatures at various depths.

Effectiveness of Shallow Temperature Surveys to Target a Geothermal Reservoir at Previously Explored Site at McGee Mountain, Nevada: Final Report for U.S. Department Of Energy Grant EE-0002830

The McGee Mountain geothermal area was selected  to test early-stage shallow temperature survey techniques and drill two slim holes to test the resource. Geothermal Technical Partners, Inc. was able to complete only a small portion of the project before lack of funding prevented further exploration work. This work included a shallow (2-meter) temperature survey, a Geoprobe survey, a close-spaced gravity survey, and several reports on geologic and transmission viability.

The 18-page report includes a description of the geothermal geology of the area, geochemistry and geothermometry of nearby springs and wells, and findings from the shallow temperature survey, Geoprobe survey, close-spaced gravity survey, heat-in-place estimate, transmission viability, and an archeological survey. The report makes the following conclusions:

Both the shallow 2-meter and the Geoprobe surveys are cost-effective methods to detect subsurface thermal anomalies in early-stage exploration, prior to more expensive temperature gradient drilling.
The major advantages of the 2-meter survey are its extreme portability (no roads needed), cost per site measurement, and low environmental impact.
The 2-meter survey's disadvantages are its inability to penetrate hard substrates and the noise effects due to solar heating of the ground.
The Geoprobe's advantages are its ability to collect temperature and uncontaminated water samples, greater depth of penetration (to 60m), relatively low cost, and low environmental impact.
The Geoprobe's disadvantages are its inability to go off-road or to penetrate hard substrates.
Costs to perform both types of surveys are low, together less than the cost of one conventional temperature gradient well. Given the potential increase in data that these surveys can provide, this is extreme value for the exploration dollar.

Geothermal Resource at the McGee Mountain Prospect, Humboldt County, Nevada

This report describes the geothermal resource at McGee Mountain, including:
1. Local geology
2. Thermal features
3. Known boreholes and temperature gradients
4. Geophysical surveys
5. Fluid geochemistry and geothermometry
6. Estimate of the heat-in-place

Description of the heat-in-place estimate:
The magnitude of the geothermal resource at McGee Mountain (Painted Hills) has been estimated using a Monte Carlo method applied to estimating heat-in-place. The method relies (along with certain other parameters) on estimates of the area, thickness and average temperature of the resource, but among these, only area has some constraint at this time. Therefore, the estimates used for thickness and temperature have been based on the characteristics of other
geothermal resources in Nevada.

Results yield a 90%-probable ("P90") thermal energy-in-place estimate of 87,300 MWth-years (that is, 90% of estimates are higher). We consider this to be a minimum likely value. At 50% probability ("P50") the estimate is 134,000 MWth-years. The recoverable portion of the preceding estimate of energy-in-place has also been estimated and converted into electrical energy, using values of recovery factor, rejection temperature, utilization factor, plant capacity factor and power plant life that are provided. The minimum (90% probable) estimate for generation potential is about 25 MWe for 30 years (or a total of 750 MWe-years) and at 50% probability the estimate is 52 MWe for 30 years (or a total of 1,560 MWe-years). These estimates are somewhat larger than a public-domain McGee resource estimate made by GeothermEx in 2004, because a 2-m deep temperature survey by Caldera has established continuance of the thermal anomaly about a half mile further north than previously documented.

This resource estimate was made without reference to the Caldera property (project area) boundary, but it is likely that the entire magnitude of estimated resource lies within it. The estimate should be regarded with caution because there needs to be subsequent proof of area, thickness, temperature and commercial permeability by means of deep drilling and testing. No heat-in-place estimate of this type should ever be used to determine the final, installed size of a well field and power plant.

A Class III Cultural Resources Inventory of Proposed Roads and Drill Pads for the McGee Mountain Geothermal Project, Humboldt County, Nevada

From July 20th to July 22nd, 2010, Chambers Group personnel conducted a cultural resources inventory of the project area. The recordation and inventory resulted in the recordation a single newly identified prehistoric site (CrNV-2-9605) and five isolated finds (CrNV-2-1490 to 1494). The prehistoric site is a small lithic scatter composed exclusively of chalcedony with two formed tools. CrNV-2-9605 is recommended as not eligible to the National Register of Historic Places (NRHP) under all Criterion. The isolated finds consist of a single prehistoric flake and four pieces of historic debris. All of the isolated finds are categorically not eligible for the NRHP per the State Protocol Agreement between the BLM and Nevada SHPO. The report included in this submission details the findings  of the study.

Alternative Geothermal Power Production Scenarios

The information given in this file pertains to Argonne life-cycle analyses (LCAs) of the plant cycle stage for a set of ten new geothermal scenario pairs, each comprised of a reference and improved case. These analyses were conducted to compare environmental performances among the scenarios and cases. The types of plants evaluated are hydrothermal binary and flash and Enhanced Geothermal Systems (EGS) binary and flash plants. Each scenario pair was developed by the levelized cost of energy (LCOE) group using the Geothermal Electricity Evaluation Model (GETEM) as a way to identify plant operational and resource combinations that could reduce geothermal power plant LCOE values. Based on the specified plant and well field characteristics (plant type, capacity, capacity factor and lifetime, and well numbers and depths) for each case of each pair, Argonne generated a corresponding set of material to power ratios (MPRs) and greenhouse gas and fossil energy ratios.

Greenhouse Gas emissions from California Geothermal Power Plants

The information given in this file represents greenhouse gas (GHG) emissions and corresponding emission rates for California flash and dry steam geothermal power plants. This stage of the life cycle is the fuel use component of the fuel cycle and arises during plant operation. Despite the fact that no fossil fuels are being consumed during operation of these plants, GHG emissions nevertheless arise from GHGs present in the geofluids and dry steam that get released to the atmosphere upon passing through the system. Data for the years of 2008 to 2012 are analyzed.

Regional Slip Tendency Analysis of the Great Basin Region

Slip and dilation tendency on the Great Basin fault surfaces (from the USGS Quaternary Fault Database) were calculated using 3DStress (software produced by Southwest Research Institute).

Slip and dilation tendency are both unitless ratios of the resolved stresses applied to the fault plane by the measured ambient stress field.
- Values range from a maximum of 1 (a fault plane ideally oriented to slip or dilate under ambient stress conditions) to zero (a fault plane with no potential to slip or dilate).
- Slip and dilation tendency values were calculated for each fault in the Great Basin. As dip is unknown for many faults in the USGS Quaternary Fault Database, we made these calculations using the dip for each fault that would yield the maximum slip or dilation tendency. As such, these results should be viewed as maximum slip and dilation tendency.
- The resulting along-fault and fault-to-fault variation in slip or dilation potential is a proxy for along-fault and fault-to-fault variation in fluid flow conduit potential.

Stress Magnitudes and directions were calculated across the entire Great Basin. Stress field variation within each focus area was approximated based on regional published data and the world stress database (Hickman et al., 2000; Hickman et al., 1998 Robertson-Tait et al., 2004; Hickman and Davatzes, 2010; Davatzes and Hickman, 2006; Blake and Davatzes 2011; Blake and Davatzes, 2012; Moeck et al., 2010; Moos and Ronne, 2010 and Reinecker et al., 2005).

The minimum horizontal stress direction (Shmin) was contoured, and spatial bins with common Shmin directions were calculated. Based on this technique, we subdivided the Great Basin into nine regions (Shmin
