Investigation and evaluation of geopressured-geothermal wells. Package No. 1 of wells-of-opportunity candidates (open access)

Investigation and evaluation of geopressured-geothermal wells. Package No. 1 of wells-of-opportunity candidates

This group of wells-of-opportunity (WOO) consists of six candidates; one in Texas and five in Cameron Parish, Louisiana. Of the latter, two of three candidates are considered to be mutually exclusive in that each exhibits good potential for testing geopressured-geothermal aquifers which are indicated to be of sufficient volume for purposes of a 30-day test. A final selection of one location may be made from these three wells, assuming all pass screening criteria, based on estimated cost of the test and the negotiation of a satisfactory agreement with the owners of the surface and/or the minerals. Information is presented on the six candidates and a short write-up is included on one other well. (MHR)

Industrial application of geothermal energy in Southeast Idaho (open access)

Industrial application of geothermal energy in Southeast Idaho

Those phosphate related and food processing industries in Southeastern Idaho are identified which require large energy inputs and the potential for direct application of geothermal energy is assessed. The total energy demand is given along with that fractional demand that can be satisfied by a geothermal source of known temperature. The potential for geothermal resource development is analyzed by examining the location of known thermal springs and wells, the location of state and federal geothermal exploration leases, and the location of federal and state oil and gas leasing activity in Southeast Idaho. Information is also presented regarding the location of geothermal, oil, and gas exploration wells in Southeast Idaho. The location of state and federal phosphate mining leases is also presented. This information is presented in table and map formats to show the proximity of exploration and development activities to current food and phosphate processing facilities and phosphate mining activities.

Chemical and isotopic composition of water from thermal and mineral springs of Washington (open access)

Chemical and isotopic composition of water from thermal and mineral springs of Washington

Waters from the thermal springs of Washington range in chemical composition from dilute Na-HCO/sub 3/ to moderately saline CO/sub 2/-charged Na-HCO/sub 3/-Cl type waters. St. Martin's Hot Spring which discharges a slightly saline Na-Cl water, is the notable exception. The dilute Na-HCO/sub 3/ waters are generally associated with granitic intrusions; the warm to hot CO/sub 2/-charged waters issue on or near the large stratovolcanoes. The dilute waters have oxygen-isotopic compositions that indicate relatively little water-rock exchange. The CO/sub 2/-charged waters are usually more enriched in oxygen-18 due to more extensive water-rock reaction. The carbon-13 in the CO/sub 2/-charged thermal waters is more depleted (-10 to -12 %) than in the cold CO/sub 2/-charged soda springs (-2 to -8%) which are also scattered throughout the Cascades. The hot and cold CO/sub 2/-charged waters are supersaturated with respect to CaCO/sub 3/, but only the hot springs are actively depositing CaCO/sub 3/. Baker, Gamma, Sulphur, and Ohanapecosh hot springs seem to be associated with thermal aquifers of more than 100/sup 0/C. As these springs occur as individual springs or in small clusters, the respective aquifers are probably of restricted size.

Identification of the mineral phases responsible for cementation of Lurgi spent oil shale

The purpose of this study is to investigate the mineralogical character of the cements that are responsible for the increased strength of the spent oil shale. Several techniques to identify the nature of the cementing agents have been used in this study. X-ray diffraction was used to identify mineral dissolution and formation; scanning electron microscopy (SEM) was used to observe the cementing agents; energy dispersive X-ray analysis (EDXA) was used to provide information on the elemental composition of both the bulk material and the cementing agents; and differential thermal analyses and thermogravimetric analyses were used to document the presence of suspected minerals that may be involved in formation of the cementing material.

Fluid saturations from electrical measurements between wells (open access)

Fluid saturations from electrical measurements between wells

The feasibility of using electrical communication between wells to determine the average interwell fluid saturation was tested with a long core and three-dimensional model reservoirs. Two methods were proposed. The first employed an oxidizing solution in one well and a reducing solution in another to obtain an electric current through the reservoir from chemical reaction; the second, an impressed current between the wells and measurement of the potential difference. Experimental determination of the overall brine saturation using the electrical fields agreed with the volumetric amounts of brine and oil with which the model reservoirs were saturated. General mapping of the saturation distribution of the three-dimensional reservoir was also possible using a finite-difference solution of Poisson's equation.

Mountaintop Mining: Background on Current Controversies (open access)

Mountaintop Mining: Background on Current Controversies

Mountaintop removal mining involves removing the top of a mountain in order to recover the coal seams contained there. This practice occurs in several Appalachian states. It creates an immense quantity of excess spoil (dirt and rock that previously composed the mountaintop), which is typically placed in valley fills on the sides of the former mountains, burying streams that flow through the valleys. Critics say that, as a result of valley fills, stream water quality and the aquatic and wildlife habitat that streams support are destroyed by tons of rocks and dirt. The mining industry argues that mountaintop mining is essential to conducting surface coal mining in the Appalachian region and that surface coal mining would not be economic or feasible there if producers were restricted from using valleys for the disposal of mining overburden. Mountaintop mining is regulated under several laws, including the Clean Water Act. This report provides background on current controversies, regulatory requirements, and legal challenges to Clean Water Act regulation of mountaintop mining. Congressional attention to these issues also is discussed.

Evaluation of mixed surfactants for improved chemical flooding (open access)

Evaluation of mixed surfactants for improved chemical flooding

Phase behavior studies were conducted using combinations of a primary surfactant component and several ethoxylated surfactants. The objective of the study is to evaluate combinations of surfactants, anionic-nonionic and anionic-anionic mixtures, that would yield favorable phase behavior and solubilization capacity. The dependence of the solution behavior on the additive surfactant structure, surfactant type, oil, surfactant proportion, salinity, HLB, and temperature was observed. The results showed that the ethoxylated surfactants can improve the solution behavior of the overall system. The increase in optimum salinity range of these solutions corresponded to an increase in the degree of ethoxylation of additive surfactant, up to a certain limit. The nonionic surfactant additives yielded much higher salinities compared to the results from the ethoxylated anionics tested. The proportion of surfactant component in solution was critical in achieving a balance between the solubilization capacity and the enhancement in the system's salinity tolerance. Some combinations of these types of surfactants showed improved solution behavior with favorable solubilization capacity. The phase inversion temperature (PIT) method has been shown to be a relatively fast method for screening candidate surfactant systems. Comparisons were made using both the conventional salinity scan and the PIT method on selected chemical systems. The results …

Results of Phase 2 postburn drilling, coring, and logging: Rocky Mountain 1 Underground Coal Gasification Test, Hanna, Wyoming (open access)

Results of Phase 2 postburn drilling, coring, and logging: Rocky Mountain 1 Underground Coal Gasification Test, Hanna, Wyoming

The Rocky Mountain 1 (RM1) Underground Coal Gasification (UCG) site consisted of two different module configurations: the controlled retracting injection point (CRIP) and elongated linked well (ELW) configurations. The postburn coring of the RM1 UCG site was designed in two phases to fulfill seven objectives outlined in Western Research Institute's Annual Project Plan for 1989 (Western Research Institute 1989). The seven objectives were to (1) delineate the areal extent of the cavities, (2) identify the extent of roof collapse, (3) obtain samples of all major cavity rock types, (4) characterize outflow channels and cavity stratigraphy, (5) characterize the area near CRIP points and ignition points, (6) further define the structural geology of the site, and (7) identify the vertical positioning of the horizontal process wells within the coal seam. Phase 1 of the coring was completed during the summer of 1989 and served to partially accomplish all seven objectives. A detailed description of Phase 1 results was presented in a separate report (Lindblom et al. 1990). Phase 2, completed during the summer of 1990, was designed to complete the seven objectives; more specifically, to further define the areal extent and location of the cavities, to evaluate the outflow channels for …

Geochemistry of thermal/mineral waters in the Clear Lake region, California, and implications for hot dry rock geothermal development (open access)

Geochemistry of thermal/mineral waters in the Clear Lake region, California, and implications for hot dry rock geothermal development

Thermal/mineral waters of the Clear Lake region are broadly classified as thermal meteoric and connote types based on chemical and isotopic criteria. Ratios of conservative components such as B/Cl are extremely different among all thermal/mineral waters of the Clear Lake region except for clusters of waters emerging from specific areas such as the Wilbur Springs district and the Agricultural Park area south of Mt. Konocti. In contrast, ratios of conservative components in large, homogeneous geothermal reservoirs are constant. Stable isotope values of Clear Lake region waters show a mixing trend between thermal meteoric and connote end-members. The latter end-member has enriched [delta]D as well as enriched d[sup l8]O, very different from typical high-temperature geothermal reservoir waters. Tritium data and modeling of ages indicate most Clear Lake region waters are 500 to > 10,000 yr., although mixing of old and young components is implied by the data. The age of end-member connate water is probably > 10,000 yr. Subsurface equilibration temperature of most thermal/mineral waters of the Clear Lake region is [le] 150[degrees]C based on chemical geothermometers but it is recognized that Clear Lake region waters are not typical geothermal fluids and that they violate rules of application of many geothermometers. …

Numerical simulation study of silica and calcite dissolution around a geothermal well by injecting high pH solutions with chelating agent. (open access)

Numerical simulation study of silica and calcite dissolution around a geothermal well by injecting high pH solutions with chelating agent.

Dissolution of silica, silicate, and calcite minerals in the presence of a chelating agent (NTA) at a high pH has been successfully performed in the laboratory using a high-temperature flow reactor. The mineral dissolution and porosity enhancement in the laboratory experiment has been reproduced by reactive transport simulation using TOUGHREACT. The chemical stimulation method has been applied by numerical modeling to a field geothermal injection well system, to investigate its effectiveness. Parameters from the quartz monzodiorite unit at the Enhanced Geothermal System (EGS) site at Desert Peak (Nevada) were used. Results indicate that the injection of a high pH chelating solution results in dissolution of both calcite and plagioclase minerals, and avoids precipitation of calcite at high temperature conditions. Consequently reservoir porosity and permeability can be enhanced especially near the injection well.

Heavy oil reservoirs recoverable by thermal technology. Annual report (open access)

Heavy oil reservoirs recoverable by thermal technology. Annual report

This volume contains reservoir, production, and project data for target reservoirs thermally recoverable by steam drive which are equal to or greater than 2500 feet deep and contain heavy oil in the 8 to 25/sup 0/ API gravity range. Data were collected from three source types: hands-on (A), once-removed (B), and twice-removed (C). In all cases, data were sought depicting and characterizing individual reservoirs as opposed to data covering an entire field with more than one producing interval or reservoir. The data sources are listed at the end of each case. This volume also contains a complete listing of operators and projects, as well as a bibliography of source material.

Heavy oil reservoirs recoverable by thermal technology. Annual report (open access)

Heavy oil reservoirs recoverable by thermal technology. Annual report

The purpose of this study was to compile data on reservoirs that contain heavy oil in the 8 to 25/sup 0/ API gravity range, contain at least ten million barrels of oil currently in place, and are non-carbonate in lithology. The reservoirs within these constraints were then analyzed in light of applicable recovery technology, either steam-drive or in situ combustion, and then ranked hierarchically as candidate reservoirs. The study is presented in three volumes. Volume I presents the project background and approach, the screening analysis, ranking criteria, and listing of candidate reservoirs. The economic and environmental aspects of heavy oil recovery are included in appendices to this volume. This study provides an extensive basis for heavy oil development, but should be extended to include carbonate reservoirs and tar sands. It is imperative to look at heavy oil reservoirs and projects on an individual basis; it was discovered that operators, and industrial and government analysts will lump heavy oil reservoirs as poor producers, however, it was found that upon detailed analysis, a large number, so categorized, were producing very well. A study also should be conducted on abandoned reservoirs. To utilize heavy oil, refiners will have to add various unit operations …

SODIUM POLYPHOSPHATE-MODIFIED CLASS C/CLASS F FLY ASH BLEND CEMENTS FOR GEOTHERMAL WELLS. (open access)

SODIUM POLYPHOSPHATE-MODIFIED CLASS C/CLASS F FLY ASH BLEND CEMENTS FOR GEOTHERMAL WELLS.

The authors investigated the usefulness of the coal combustion by-products, Class C fly ash (C) and Class F fly ash (F), in developing cost-effective acid-resistant phosphate-based cements for geothermal wells. In the temperature range of 20-100 C, sodium polyphosphate (NaP) as the acidic cement-forming solution preferentially reacted with calcium sulfate and lime in the C as the base solid reactant through the exothermic acid-base reaction route, rather than with the tricalcium aluminate in C. This reaction led to the formation of hydroxyapatite (HOAp). In contrast, there was no acid-base reaction between the F as the acidic solid reactant and NaP. After autoclaving the cements at 250 C, a well-crystallized HOAp phase was formed in the NaP-modified C cement that was responsible for densifying the cement's structure, thereby conferring low water permeability and good compressive strength on the cement. however, the HOAp was susceptible to hot CO{sub 2}-laden H{sub 2}SO{sub 4} solution (pH 1.1), allowing some acid erosion of the cement. On the other hand, the mullite in F hydrothermally reacted with the Na from NaP to form the analcime phase. Although this phase played a pivotal role in abating acid erosion, its generation created an undesirable porous structure in the …

Inventory of thermal springs and wells within a one-mile radius of Yucca Lodge, Truth or Consequences, New Mexico (open access)

Inventory of thermal springs and wells within a one-mile radius of Yucca Lodge, Truth or Consequences, New Mexico

Equity Management Corporation proposes (1) to build about 30 condominiums at the present site of the Yucca Lodge, Truth or Consequences, New Mexico and (2) to heat the condominiums with the natural thermal waters that discharge from the property. To do so the corporation must satisfy the rules and regulations of four state and federal agencies. To satisfy some of the data requirements of these agencies and to provide basic data on the geohydrology of the area this report provides the results of a field inventory of the springs and wells within one mile of the lodge. Table 1 summarizes the data for eight springs and three sites where springs once issued. Table 2 summarizes the data on forty-four operable wells and thirty wells that are unusable in their present condition. Appendices list (1) wells presumed to be in the area but not located during field inspection and (2) wells that could be in the area, but were found to be beyond the one-mile radius. Temperature and specific conductance of the water show only minor variation within the recognized hot-water.
