Hawaii basic data for thermal springs and wells as recorded in geotherm

GEOTHERM sample file contains 34 records for Hawaii. The high average ambient air temperature found on the Hawaiian Islands required fluid samples to have a temperature of at least 30/sup 0/C to be included. A computer-generated index is found in appendices A of this report. The index give one line summaries of each GEOTHERM record describing the chemistry of geothermal springs and wells in the sample file for Hawaii. The index is found in appendix A (p. is sorted by county and by the name of the source. Also given are well number (when appropriate), site type (spring, well, fumarole), latitude, longitude (both use decimal minutes), GEOTHERM record identifier, and temperature (/sup 0/C). In conducting a search of Appendix A, site names are quite useful for locating springs or wells for which a specific name is commonly used, but sites which do not have specific names are more difficult to locate.

Results of the Radiological Survey at 106 Columbia Lane, Lodi, New Jersey (LJ063) (open access)

Results of the Radiological Survey at 106 Columbia Lane, Lodi, New Jersey (LJ063)

Maywood Chemical Works (MCW) of Maywood, New Jersey, generated process wastes and residues associated with the production and refining of thorium and thorium compounds from monazite ores from 1916 to 1956. MCW supplied rare earth metals and thorium compounds to the Atomic Energy Commission and various other government agencies from the late 1940s to the mid-1950s. Area residents used the sandlike waste from this thorium extraction process mixed with tea and cocoa leaves as mulch in their yards. Some of these contaminated wastes were also eroded from the site into Lodi Brook. At the request of the US Department of Energy (DOE), a group from Oak Ridge National Laboratory conducts investigative radiological surveys of properties in the vicinity of MCW to determine whether a property is contaminated with radioactive residues, principally {sup 232}Th, derived from the MCW site. The survey typically includes direct measurement of gamma radiation levels and soil sampling for radionuclide analyses. The survey of this site, 106 Columbia Lane, Lodi, New Jersey (LJ063), was conducted during 1987. Results of the survey demonstrated radionuclide concentrations in excess of the DOE Formerly Utilized Sites Remedial Action Program criteria. The radionuclide distributions are typical of the type of material originating …

Work Plan: Targeted Investigation to Assess Current Conditions Associated With the Carbon Tetrachloride Plume Downgradient From the Former CCC/Usda Facility at Milford, Nebraska. (open access)

Work Plan: Targeted Investigation to Assess Current Conditions Associated With the Carbon Tetrachloride Plume Downgradient From the Former CCC/Usda Facility at Milford, Nebraska.

The Commodity Credit Corporation of the U.S. Department of Agriculture (CCC/USDA) formerly operated a grain storage facility at Milford, Nebraska. In May 2008, the CCC/USDA directed the Environmental Science Division of Argonne National Laboratory, as its technical consultant, to develop a work plan for a targeted investigation at the Milford site. The purpose of the targeted investigation is to assess the current extent and configuration of the carbon tetrachloride plume downgradient from the former CCC/USDA facility and proximal to the banks of the Big Blue River, which borders the area of concern to the east, southeast, and northeast. In 1995, carbon tetrachloride contamination was detected by the Nebraska Department of Health and Human Services in a private drinking water well and a livestock well 1.25 mi south of Milford (Figure 1.1). The Trojan drinking water well is located directly downgradient (approximately 300 ft east) of the former CCC/USDA facility. Low levels of carbon tetrachloride contamination were also found in the Troyer livestock well, approximately 1,200 ft north of the former CCC/USDA facility.

Mitigation action plan for remedial action at the Uranium Mill Tailing Sites and Disposal Site, Rifle, Colorado (open access)

Mitigation action plan for remedial action at the Uranium Mill Tailing Sites and Disposal Site, Rifle, Colorado

The Estes Gulch disposal site is approximately 10 kilometers (6 miles) north of the town of Rifle, off State Highway 13 on Federal land administered by the Bureau of Land Management. The Department of Energy (DOE) will transport the residual radioactive materials (RRM) by truck to the Estes Gulch disposal site via State Highway 13 and place it in a partially below-grade disposal cell. The RRM will be covered by an earthen radon barrier, frost protection layers, and a rock erosion protection layer. A toe ditch and other features will also be constructed to control erosion at the disposal site. After removal of the RRM and disposal at the Estes Gulch site, the disturbed areas at all three sites will be backfilled with clean soils, contoured to facilitate surface drainage, and revegetated. Wetlands areas destroyed at the former Rifle processing sites will be compensated for by the incorporation of now wetlands into the revegetation plan at the New Rifle site. The UMTRA Project Office, supported by the Remedial Action Contractor (RAC) and the Technical Assistance Contractor (TAC), oversees the implementation of the MAP. The RAC executes mitigation measures in the field. The TAC provides monitoring of the mitigation actions in …

Seminoe-Kortes transmission line/substation consolidation project, Carbon County, Wyoming (open access)

Seminoe-Kortes transmission line/substation consolidation project, Carbon County, Wyoming

The existing switchyards at Western Area Power Administration's (WESTERN) Seminoe and Kortes facilities, located approximately 40 miles northeast of Rawlines, Carbon County, Wyoming, were constructed in 1939 and 1951, respectively. The circuit breakers at these facilities are beyond or approaching their service life and need to be replaced. In addition, the switchyards have poor access for maintenance and replacement of equipment, and their locations create potential for oil spills into the North Platte River. WESTERN is proposing to consolidate the switchyard facilities into one new substation to provide easier access, restore proper levels of system reliability, and decrease the potential for oil contamination of the river. This environmental assessment (EA) was prepared to evaluate the impacts of the proposed Seminoe-Kortes Consolidation Project. 57 refs., 12 figs., 8 tabs.

Environmental impact assessment: chemical explosive fracturing project, Petroleum Technology Corporation/Sutton County, Texas (open access)

Environmental impact assessment: chemical explosive fracturing project, Petroleum Technology Corporation/Sutton County, Texas

The Nevada Operations Office of the Energy Research and Development Administration (ERDA) has contracted with Petroleum Technology Corporation (PTC) to perform a gas stimulation program by chemical explosive fracturing (CEF) in the Canyon sands of the Val Verde - Kerr Basin of Sutton County, Texas. This lenticular tight sand deposit, underlying much of southwestern Texas, contains large volumes of natural gas. To date this formation has yielded only marginal amounts of gas because of its low porosity and permeability. The semi-arid environment of the Aldwell/Sawyer field is characterized by dry arroyos and xeric vegetation. Population is sparse and sheep ranching is the primary occupation. Because of the existence of previously drilled oil and gas wells, road and pipeline construction will be minimal. Impacts from this two well project are expected to be minimal and be confined to temporary surface disruption and increased erosion at the well site.

Brine chemistry: scaling and corrosion. Geothermal research study in the Salton Sea region of California

The purpose of this report is to recommend a reasonable program of brine chemistry research that will result in the development of methods for predicting and controlling scale deposition, and in guidelines for the selection of corrosion-resistant construction materials. First, background information, which is necessary for the understanding of the problems of scaling and corrosion in the Salton Sea KGRA, is presented through a review of the history of geothermal exploration and development in the Salton Sea. Second, literature relevant to the geochemistry of the Salton Sea field is reviewed and important results are emphasized. Third, current research efforts directed toward actual power plant construction are summarized and evaluated. Fourth, research which has been proposed but is not currently funded is discussed. Fifth, because silica scaling has been the most troublesome problem in the past, the basic chemistry of silica and its relationship to scaling is discussed. Sixth, recommendations for future research are made in which a fundamental engineering approach is emphasized. In this approach, experiments would be conducted on actual process equipment and detailed chemical analyses would be performed on site in well-equipped field laboratories. 88 references.

Trends in Heavy Oil Production and Refining in California (open access)

Trends in Heavy Oil Production and Refining in California

This report is one of a series of publications assessing the feasibility of increasing domestic heavy oil production and is part of a study being conducted for the US Department of Energy. This report summarizes trends in oil production and refining in Canada. Heavy oil (10{degrees} to 20{degrees} API gravity) production in California has increased from 20% of the state`s total oil production in the early 1940s to 70% in the late 1980s. In each of the three principal petroleum producing districts (Los Angeles Basin, Coastal Basin, and San Joaquin Valley) oil production has peaked then declined at different times throughout the past 30 years. Thermal production of heavy oil has contributed to making California the largest producer of oil by enhanced oil recovery processes in spite of low oil prices for heavy oil and stringent environmental regulation. Opening of Naval Petroleum Reserve No. 1, Elk Hills (CA) field in 1976, brought about a major new source of light oil at a time when light oil production had greatly declined. Although California is a major petroleum-consuming state, in 1989 the state used 13.3 billion gallons of gasoline or 11.5% of US demand but it contributed substantially to the Nation`s energy …

C.D. Hopkins Et. Al. No. 2 Geothermal Well-of-Opportunity, Wayne County, Georgia; Operational Report

On December 8, 1977, Gruy Federal, Inc. took over the C.D. Hopkins et al. No. 2 well, located near Jesup in Wayne County, Georgia, to be deepened and used for geothermal temperature-gradient measurements. The well was drilled from 4,009 to 4,341 feet, then diamond cored to 4,371 feet, 28 feet of core being obtained for analysis. After logging by the USGS District Groundwater Office in Atlanta, the well was terminated with 3 1/2 inch tubing to 4,386 feet. Scientists from Virginia Polytechnic Institute determined the bottom-hole temperature to be 60 C (140 F) at 1,331 meters (4,365 feet). Over the interval 47-1,331 meters (154-4,365 feet) the least-squares temperature gradient was 29.3 {+-} 0.14 C/km (1.61 {+-} 0.25 F/100 ft).

The Influence of fold and fracture development on reservoir behavior of the Lisburne Group of northern Alaska: Final Report (open access)

The Influence of fold and fracture development on reservoir behavior of the Lisburne Group of northern Alaska: Final Report

The Carboniferous Lisburne Group is a major carbonate reservoir unit in northern Alaska. The Lisburne is folded and thrust faulted where it is exposed throughout the Brooks Range, but is relatively undeformed in areas of current production in the subsurface of the North Slope. The objectives of this study were to develop a better understanding of four major aspects of the Lisburne: (1) The geometry and kinematics of folds and their truncation by thrust faults. (2) The influence of folding on fracture patterns. (3) The influence of deformation on fluid flow. (4) Lithostratigraphy and its influence on folding, faulting, fracturing, and reservoir characteristics. Symmetrical detachment folds characterize the Lisburne in the northeastern Brooks Range. In contrast, Lisburne in the main axis of the Brooks Range is deformed into imbricate thrust sheets with asymmetrical hangingwall anticlines and footwall synclines. The Continental Divide thrust front separates these different structural styles in the Lisburne and also marks the southern boundary of the northeastern Brooks Range. Field studies were conducted for this project during 1999 to 2001 in various locations in the northeastern Brooks Range and in the vicinity of Porcupine Lake, immediately south of the Continental Divide thrust front. Results are summarized below …

Analysis of Devonian Black Shales in Kentucky for Potential Carbon Dioxide Sequestration and Enhanced Natural Gas Production Quarterly Report: April-June 2005 (open access)

Analysis of Devonian Black Shales in Kentucky for Potential Carbon Dioxide Sequestration and Enhanced Natural Gas Production Quarterly Report: April-June 2005

Devonian gas shales underlie approximately two-thirds of Kentucky. In the shale, natural gas is adsorbed on clay and kerogen surfaces. This is analogous to methane storage in coal beds, where CO{sub 2} is preferentially adsorbed, displacing methane. Black shales may similarly desorb methane in the presence of CO{sub 2}. Drill cuttings from the Kentucky Geological Survey Well Sample and Core Library were sampled to determine CO{sub 2} and CH{sub 4} adsorption isotherms. Sidewall core samples were acquired to investigate CO{sub 2} displacement of methane. An elemental capture spectroscopy log was acquired to investigate possible correlations between adsorption capacity and mineralogy. Average random vitrinite reflectance data range from 0.78 to 1.59 (upper oil to wet gas and condensate hydrocarbon maturity range). Total organic content determined from acid-washed samples ranges from 0.69 to 14 percent. CO{sub 2} adsorption capacities at 400 psi range from a low of 14 scf/ton in less organic-rich zones to more than 136 scf/ton. There is a direct correlation between measured total organic carbon content and the adsorptive capacity of the shale; CO{sub 2} adsorption capacity increases with increasing organic carbon content. Initial estimates based on these data indicate a sequestration capacity of 5.3 billion tons of CO{sub …

CO2 Sequestration Potential of Texas Low-Rank Coals Quarterly Report (open access)

CO2 Sequestration Potential of Texas Low-Rank Coals Quarterly Report

The objectives of this project are to evaluate the feasibility of carbon dioxide (CO{sub 2}) sequestration in Texas low-rank coals and to determine the potential for enhanced coalbed methane (CBM) recovery as an added benefit of sequestration. The main tasks for this reporting period were to correlate well logs and refine coal property maps, evaluate methane content and gas composition of Wilcox Group coals, and initiate discussions concerning collection of additional, essential data with Anadarko. To assess the volume of CO{sub 2} that may be sequestered and volume of methane that can be produced in the vicinity of the proposed Sam Seymour sequestration site, we used approximately 200 additional wells logs from Anadarko Petroleum Corp. to correlate and map coal properties of the 3 coal-bearing intervals of Wilcox group. Among the maps we are making are maps of the number of coal beds, number of coal beds greater than 5 ft thick, and cumulative coal thickness for each coal interval. This stratigraphic analysis validates the presence of abundant coal for CO{sub 2} sequestration in the Wilcox Group in the vicinity of Sam Seymour power plant. A typical wellbore in this region may penetrate 20 to 40 coal beds with cumulative …

Exploitation and Optimization of Reservoir Performance in Hunton Formation, Oklahoma Quarterly Technical Progress Report: April-June 2003

West Carney Field produces from Hunton Formation. All the wells produce oil, water and gas. The main objective of this study is to understand the unique behavior observed in the field. We would also like to extend the analysis to other similar fields. This report specifically addresses two issues relevant to our understanding of the West Carney reservoir. In the first part, we discuss our efforts to develop the geological model which can help us understand how the depositional environment affects the producing behavior. In the previous Budget Period, we described fourteen cores. In this report, we present preliminary analysis of several additional cores and conodont work. Based on the additional data collected, it is clear that the earlier geological model is simplified and needs to be updated. The complexity in geological environment can explain some of the unusual behavior observed in the field production. The second issue deals with how to develop a model for gauging a potential success of a dewatering project. We have a developed hypothesis regarding what makes it successful, however, we need to test it against the available data. We have started collecting data from other fields producing from Hunton formation so that we can …

Carbon Sequestration in Reclaimed Mined Soils of Ohio (open access)

Carbon Sequestration in Reclaimed Mined Soils of Ohio

This research project is aimed at assessing the soil organic carbon (SOC) sequestration potential of reclaimed minesoils (RMS). The experimental sites, owned and maintained by the American Electrical Power, are located in Guernsey, Morgan, Noble, and Muskingum Counties of Ohio. These sites, characterized by age chronosequences, were reclaimed with and without topsoil application and are under continuous grass or forest cover. During this quarter, bulk and core soil samples were collected from all 13 experimental sites for 0-15 cm, 15-30 cm, and 30-50 cm depths. In addition, 54 experimental plots (4 x 4 m) were established at three separate locations on reclaimed minesites to assess the influence of compost application on SOC during project period 2. This report presents the results from two sites reclaimed during 1978. The first site is under grass and the other under forest cover. The soil bulk density ({rho}{sub b}), SOC, total nitrogen (TN) concentrations and stocks were determined for these two sites on a 20 x 20 m grid. The preliminary analysis showed that the {rho}{sub b} ranged from 0.88 Mg m{sup -3} to 1.16 Mg m{sup -3} for 0-15 cm, 0.91 Mg m{sup -3} to 1.32 Mg m{sup -3} for 15-30 cm, and …
