2011 Geothermal Technologies Program Peer Review Presentation summarizing relevance, proposed approach, and logistics of the Glass Buttes Exploration and Drilling.

The University of Hawaii at Manoa conducted a Play Fairway Analysis of the state of geothermal potential for the islands. Phase I included the aggregation of all existing geologic, geophysical and geochemical data available. A probability model incorporating heat, fluid, and permeability was then created to assess the probability of viable geothermal development. Phase II is the focus of this paper, with new data collection as the goal for this funding period. The Play Fairway Project collected new geothermal groundwater data from 60 wells and 1 spring across the State of Hawaii. Geochemical geothermal indicators used previously in Hawaii, and around the world, were investigated for the newly acquired data in Phase II. These indicators include groundwater temperature, chloride:magnesium ratios, sulfate:chloride ratios, and silica concentrations. All chemical analyses were collected by ... the Play Fairway team and analyzed at various labs at the University of Hawaii at Manoa. Of the ten target areas identified for Phase II, two of the sites provide encouraging groundwater geochemical results for potential geothermal resources. These sites include the Southwest Rift Zone of Haleakala, Maui, and the Palawai Basin, Lanai. Multiple geothermal indicators have been observed in these areas and, therefore, provide encouragement to further explore for subsurface heat. Further investigation is recommended in these target areas through geological, geophysical, and geochemical exploration. The Hawaii Play Fairway project was funded by the U.S. Department of Energy Geothermal Technologies Office, and the Hawaii Groundwater and Geothermal Resources Center (Hawaii Institute of Geophysics and Planetology, University of Hawaii at Manoa) executed the project.

Field data and 222Rn activities from the Altona well field. 222Rn, the most stable isotope of radon, was tested for during well extraction experiments. Tracers were also tracked to monitor the well. Data include 222Rn activities and complimentary geochemical data for multiple field experiments as part of an EGS project.

A database of geochemical data from potential geothermal sources aggregated from multiple sources as of March 2010. The database contains fields for the location, depth, temperature, pH, total dissolved solids concentration, chemical composition, and date of sampling. A separate tab contains data on non-condensible gas compositions. The database contains records for over 50,000 wells, although many entries are incomplete. Current versions of source documentation are listed in the dataset.

Specific efforts summarized in this report include the following: • Analysis of rock samples within the CO2 injection zone (Muddy Formation) as well as on the sealing formations (Niobrara and Mowry Formations) to determine their petrographic, petrophysical, and mineralogical characteristics. • Reservoir fluid sampling and analysis to characterize the formation water chemistry and to better understand the hydrocarbon composition of the reservoir. • Surface water, groundwater, and shallow vadose zone soil gas sampling and analysis to establish baseline characteristics of surface and shallow subsurface environments prior to CO2 injection. v • Preliminary review of existing literature to identify potential mineralogical effects of CO2 injection within the Bell Creek reservoir and cap rock and also within the overlying groundwater zones in the unlikely event of out-of-zone migration. • Laboratory-based CO2 exposure testing of rock and water samples from the lowest groundwater zone (Hell Creek Formation) overlying the Bell Creek reservoir to better understand the possible effects of out-of-zone CO2 migration to the shallow subsurface.

These brine samples are collected from the Soda Geyser (a thermal feature, temperature ~30 C) in Soda Springs, Idaho. These samples also represent the overthrust brines typical of oil and gas plays in western Wyoming. Samples were collected from the source and along the flow channel at different distances from the source. By collecting and analyzing these samples we are able to increase the density and quality of data from the western Wyoming oil and gas plays. Furthermore, the sampling approach also helped determine the systematic variation in REE concentration with the sampling distance from the source. Several geochemical processes are at work along the flow channels, such as degassing, precipitation, sorption, etc.

From its inception in May of 1982, the U.S. Department of Energy Deep Source Gas project has investigated the possibility that significant quantities of hydrocarbons, natural gas in particular, may be generated during and following convergent plate tectonic sediment subduction. Sediment subduction is believed to have been an important process during the past 180 million years along the western margin of North America. Several years of regional geological, and limited geochemical investigations led to the theory that some portion of these subducted sedimentary units may have been left in place in the upper crust of the continental plate margin of this region. The potential for these, in part, deeply buried rocks to generate petroleum, and to contain important quantities of natural gas at drillable depths, was at the heart of this effort. Along with Gas Hydrates, the Deep Source Gas program of the Morgantown Energy Technology Center was structured under the heading of Speculative Gas Resources being investigated in frontier areas of the U.S. Following an initial reconnaissance geophysical effort in the Pacific Northwest and Alaska, which included the use of magnetotellurics (MT), gravity, and magnetics information, an important high conductivity MT anomaly was identified in southwest Washington. This feature later identified as the Southern Washington Cascades Conductor, or SWCC, was of sufficient areal extent to warrant further study for its potential as a deeply buried subduction system with significant sedimentary section. Approximately 238 kilometers of 1024 channel deep seismic reflection data were collected in 1988, 1989 and 1990 across the SWCC anomaly in six seismic lines. At this time approximately half of the data has been analyzed and released in the following publications: U.S. Geological Survey, Open File Report 91-119 entitled "Are Hydrocarbon Source Rocks Hidden Beneath the Volcanic Flows in the Southern Washington Cascades?" by W.

Fort Nelson CCS Project Updates from September 1, 2010.

Suites of new geophysical and geochemical surveys provide evidence for geothermal resource at the Haleakala Southwest Rift Zone (HSWRZ) on Maui Island, Hawai'i. This poster outlines the Site's background, the geophysical surveys conducted on the Site (LiDAR, gravity and magnetics), the geochemiclal surveys conducted on the Site (CO2 flux), and summarizes the recent findings and conclusions.

A binational effort between the United States and Canada is under way to characterize the lowermost aquifer system in the Williston and Alberta Basins of the northern Great Plains prairie region of North America in the United States and Canada. This 3-year project, begun in 2011, is being conducted with the goal of determining the potential for geologic storage of carbon dioxide (CO2) in rock formations of the 1.34 million-km2 Cambro-Ordovician saline system (COSS). The focus of this report is to evaluate and discuss geochemical modeling and laboratory studies performed by the Energy & Environmental Research Center to determine potential chemical reactions between CO2, brine, and rock on the portion of the COSS that occurs in North Dakota, Montana, and South Dakota. Although the modeling and laboratory activities were conducted independently, the results of the two different activities were compared to each other to establish a greater understanding of the validity and applicability of the modeling and laboratory approaches. The geochemical modeling study was performed using publicly available PHREEQC software and databases. Rock samples, mineralogy, and water analysis data for both the sandstone injection target and the shale cap rock were also obtained from publicly available sources. The laboratory-based exposure tests entailed exposure of various COSS rock samples to CO2 for 28 days at formation pressure and temperature. The results of the geochemical modeling were consistent with existing literature, and suggested that because most of the COSS comprises quartz-rich sandstone, much of the rock matrix will be nonreactive. Reactions can, however, occur with secondary components (clays, carbonates, micas, K-feldspar) that can be contained within the sandstone and the heterogeneous mixed lithology zones between the primary sand layers. The geochemical modeling study predicted that a geochemical effect from the interaction of CO2 with the COSS minerals and formation water was the dissolution of calcite and concurrent formation of dolomite. The source of Mg2+ for this reaction was either from Mg2+ contained within secondary formation minerals, such as illite, phlogopite, celadonite, and clinochlore, or from Mg2+ in the formation water. The modeling calculations also indicated a potential reaction of the CO2 with illite and K-feldspar in the formation. The K-feldspar was predicted to decompose into quartz, clay, and carbonates, thus trapping the CO2 in a mineral form. vi The results of the laboratory experiments generally compared favorably with the modeling portion of the study. The analytical data generated from the exposed samples show a variable mix of concentrations of K-feldspar and a general trend of decreases in illite. Illite and Kfeldspar behaviors were generally in agreement with the geochemical modeling results. The most significant reactions occurred between CO2 and dolomite/calcite and glauconite in the sandstone. Glauconite contained within samples completely dissolved and decomposed during the exposure experiments. The decomposition of glauconite will form siderite and quartz as well as some ions that will remain in solution. This phenomenon in glauconite-rich areas may increase local permeability as well as provide a mineral-trapping mechanism for CO2. Samples of shale that were exposed to CO2 showed no change in morphology or chemistry, with the exception of halite precipitation. The formation of halite that was seen is most likely an artifact of the samples being dried (not rinsed) after exposure to CO2 and brine solutions. The modeling calculations and laboratory experiments both suggest that CO2 interactions with the COSS mineral phases (reservoir and cap rock) are not detrimental to CO2 storage. Large areal changes in porosity and permeability are not anticipated from the interactions of CO2 with the COSS. Minerals within the COSS that did react with CO2 are typically found in lower concentrations in the quartz-dominated sandstone or within the low-porosity cap rock. Any reactions with the cap rock are not likely to penetrate past the CO2–cap rock interface because of low porosity/permeability. Variations in formation water chemistry, mineral content, and porosity in the COSS can result in large variations in the amount of CO2 that can be trapped. These variations occur both geographically between different areas of the COSS and vertically at each location. Additional focused efforts are needed on both the modeling and rock–CO2 exposure fronts to better understand the potential effects of CO2 storage in the COSS. With respect to future modeling efforts, additional data are necessary for more robust calculations to address the effects of pressure, kinetics, and concentrated brines in the COSS. Laboratory-based CO2 exposure experiments could be improved by implementing more advanced sampling methodologies for highly heterogeneous rocks to ensure that observed differences in chemistry are accurate. Heterogeneity in the rock samples provides for challenging interpretation of results when minute changes in chemistry are observed. Improvements to the CO2 exposure methodology to allow for better detection of minute mineralogical changes within the rock fabric will greatly aid in the refinement of this experimental process.

Final Report describing regional signature detection for blind and traditional play fairways as part of Phase I of New Mexico Play Fairway Analysis. This project seeks to reduce exploration risk and identify new prospective targets using available geologic, geochemical, and geophysical data sets. Although this project focuses on southwestern New Mexico, the techniques that were developed during this project are widely applicable elsewhere, particularly in arid regions.

The National Cooperative Soil Survey - Soil Characterization Database (NCSS-SCD) contains laboratory data for more than 65,000 locations (i.e. xy coordinates) throughout the United States and its Territories, and about 2,100 locations from other countries. It is a compilation of data from the Kellogg Soil Survey Laboratory (KSSL) and several cooperating laboratories. The data steward and distributor is the National Soil Survey Center (NSSC). Information contained within the database includes physical, chemical, biological, mineralogical, morphological, and mid infrared reflectance (MIR) soil measurements, as well a collection of calculated values. The intended use of the data is to support interpretations related to soil use and management. Data Usage Access to the data is provided via the following user interfaces: 1. Interactive Web Map 2. Lab Data Mart (LDM) for querying data and generating reports 3. Soil Data Access (SDA) web services for querying data 5. Direct download of the entire database in several formats Data at each location includes measurements at multiple depths (e.g. soil horizons). However, not all analyses have been conducted for each location and depth. Typically, a suite of measurements was collected based upon assumed or known conditions regarding the soil being analyzed. For example, soils of arid environments are routinely analyzed for salts and carbonates as part of the standard analysis suite. Standard morphological soil descriptions are available for about 60,000 of these locations. Mid-infrared (MIR) spectroscopy is available for about 7,000 locations. Soil fertility measurements, such as those made by Agricultural Experiment Stations, were not made. Most of the data were obtained over the last 40 years, with about 4,000 locations before 1960, 25,000 from 1960-1990, 27,000 from 1990-2010, and 13,000 from 2010 to 2021. Generally, the number of measurements recorded per location has increased over time. Typically, the data were collected to represent a soil series or map unit component concept. They may also have been sampled to determine the range of variation within a given landscape. Although strict quality-control measures are applied, the NSSC does not warrant that the data are error free. Also, in some cases the measurements are not within the applicability range of the laboratory methods. For example, dispersion of clay is incomplete in some soils by the standard method used for determining particle-size distribution. Soils producing incomplete dispersion include those that are derived from volcanic materials or that have a high content of iron oxides, gypsum, carbonates, or other cementing materials. Also note that determination of clay minerals by x-ray diffraction is relative. Measurements of very high or very low quantities by any method are not very precise. Other measurements have other limitations in some kinds of soils. Such data are retained in the database for research purposes. Also, some of the data for were obtained from cooperating laboratories within the NCSS. The accuracy of the location coordinates has not been quantified but can be inferred from the precision of their decimal degrees and the presence of a map datum. Some older records may correspond to a county centroid. When the map datum is missing it can be assumed that data prior to 1990 was recorded using NAD27 and with WGS84 after 1995.

We summarized the FY17 and part of FY18 results of the analysis of the effect of several parameters (e.g., total dissolved solids, specific competing metals, pH, and temperature) on REE recovery from geothermal brine in a manuscript that was submitted to Environmental Science & Technology. In this manuscript, we investigate biosorption as a potential means of recovering REEs from geothermal fluids, a low-grade but abundant REE source. We have previously engineered E. coli to express lanthanide binding tags (LBTs) on the cell surface and the resulting strain showed an increase in both REE adsorption capacity and selectivity. Here we examined how REE adsorption by the engineered E. coli is affected by various geochemical factors relevant to geothermal fluids, including total dissolved solids (TDS), temperature, pH, and the presence of competing trace metals.

This study is a joint effort by the University of Wyoming (UW), the UW Engineering Department (UW-ENG), and Idaho National Laboratories (INL) and the United States Geological Survey (USGS) to describe rare earth element concentrations in oil and gas produced waters. In this work we present the Rare Earth Element (REE) and trace metal character of produced water in several oil and gas fields and three coal fired power stations.

This work was developed to complement the geochemical assessments of produced water and geothermal water samples. Specifically, this task was designed to test the influence of reservoir rock-type and corresponding mineralogy/geochemistry on the concentrations of REE found in oil and gas produced waters. There has been no direct investigation of REE reactions relative to rock-type in deep oil and gas brine prior to this investigation.

The Glass Buttes Project includes combining a suite of high-resolution geophysical and geochemical techniques to reduce exploration risk by characterizing hydrothermal alteration, fault geometries and relationships. This is aided through geologic observation, modern remote sensing and geophysical techniques which analyze and structurally model this area prior to siting and drilling.
