Horizontal stirring in the global ocean  

E-Print Network (OSTI)

Horizontal mixing and the distribution of coherent structures in the global ocean are analyzed using Finite-Size Lyapunov Exponents (FSLE), computed for the surface velocity field derived from the Ocean general circulation model For the Earth Simulator (OFES). FSLEs measure horizontal stirring and dispersion; additionally, the transport barriers which organize the oceanic flow can roughly be identified with the ridges of the FSLE field. We have performed a detailed statistical study, particularizing for the behaviour of the two hemispheres and different ocean basins. The computed Probability Distributions Functions (PDFs) of FSLE are broad and asymmetric. Horizontal mixing is generally more active in the northern hemisphere than in the southern one. Nevertheless the Southern Ocean is the most active ocean, and the Pacific the less active one. A striking result is that the main currents can be classified in two 'activity classes': Western Boundary Currents, which have broad PDFs with large FSLE values, and Eas...

Global horizontal irradiance clear sky models : implementation and analysis.  

SciTech Connect

Clear sky models estimate the terrestrial solar radiation under a cloudless sky as a function of the solar elevation angle, site altitude, aerosol concentration, water vapor, and various atmospheric conditions. This report provides an overview of a number of global horizontal irradiance (GHI) clear sky models from very simple to complex. Validation of clear-sky models requires comparison of model results to measured irradiance during clear-sky periods. To facilitate validation, we present a new algorithm for automatically identifying clear-sky periods in a time series of GHI measurements. We evaluate the performance of selected clear-sky models using measured data from 30 different sites, totaling about 300 site-years of data. We analyze the variation of these errors across time and location. In terms of error averaged over all locations and times, we found that complex models that correctly account for all the atmospheric parameters are slightly more accurate than other models, but, primarily at low elevations, comparable accuracy can be obtained from some simpler models. However, simpler models often exhibit errors that vary with time of day and season, whereas the errors for complex models vary less over time.

Validation of the NSRDB-SUNY global horizontal irradiance in California  

Science Conference Proceedings (OSTI)

Satellite derived global horizontal solar irradiance (GHI) from the SUNY modeled dataset in the National Solar Radiation Database (NSRDB) was compared to measurements from 27 weather stations in California during the years 1998-2005. The statistics of spatial and temporal differences between the two datasets were analyzed and related to meteorological phenomena. Overall mean bias errors (MBE) of the NSRDB-SUNY indicated a GHI overprediction of 5%, which is smaller than the sensor accuracy of ground stations. However, at coastal sites, year-round systematic positive MBEs in the NSRDB-SUNY data up to 18% were observed and monthly MBEs increased up to 54% in the summer months during the morning. These differences were explained by a tendency for the NSRDB-SUNY model to overestimate GHI under cloudy conditions at the coast during summer mornings. A persistent positive evening MBE which was independent of site location and cloudiness occurred at all stations and was explained by an error in the time-shifting method applied in the NSRDB-SUNY. A correction method was derived for these two errors to improve the accuracy of the NSRDB-SUNY data in California. (author)

Response of precipitation extremes to idealized global warming in an aqua-planet climate model: Towards robust projection across different horizontal resolutions  

Science Conference Proceedings (OSTI)

Current climate models produce quite heterogeneous projections for the responses of precipitation extremes to future climate change. To help understand the range of projections from multimodel ensembles, a series of idealized 'aquaplanet' Atmospheric General Circulation Model (AGCM) runs have been performed with the Community Atmosphere Model CAM3. These runs have been analysed to identify the effects of horizontal resolution on precipitation extreme projections under two simple global warming scenarios. We adopt the aquaplanet framework for our simulations to remove any sensitivity to the spatial resolution of external inputs and to focus on the roles of model physics and dynamics. Results show that a uniform increase of sea surface temperature (SST) and an increase of low-to-high latitude SST gradient both lead to increase of precipitation and precipitation extremes for most latitudes. The perturbed SSTs generally have stronger impacts on precipitation extremes than on mean precipitation. Horizontal model resolution strongly affects the global warming signals in the extreme precipitation in tropical and subtropical regions but not in high latitude regions. This study illustrates that the effects of horizontal resolution have to be taken into account to develop more robust projections of precipitation extremes.

Science Conference Proceedings (OSTI)

Repast now supports the reading, writing, and display of shapefile data. In the Repast-GIS integration, these tasks are generally broken up into two different classes, a data class, and a display class. The data class allows data to be read into Repast from the GIS, and written out from Repast into a GIS format. The current implementation of GIS in Repast is focused on two systems: ESRI ArcMap and OpenMap. This paper will elucidate how to use each of these systems with Repast.

Purpose GIS Naming Conventions  

E-Print Network (OSTI)

This document describes guidelines for naming of GIS-related folders, files, attribute tables, and fields for the North Coast and Cascades Network (NCCN) and helps to fulfill the requirements for GIS deliverables developed as part of Inventory and Monitoring (I&M) Program natural resource studies. The primary objective of this document is to improve GIS data quality and usability by establishing a consistent file naming convention for working and final shared, geo-referenced data sets within the NCCN. These guidelines propose clear filename creation methods in order to minimize confusion, errors, and unnecessary support when GIS data are exchanged among users. Two competing objectives need to be balanced: to make a dataset name easily understood and as short as possible for use in various software systems. Longer field names, sometimes resulting from long dataset names and sometimes created by users, are often truncated during data exchange or format conversion, which could unintentionally create non-unique field names. These guidelines will: promote consistency in GIS layer and attribute (variable or field) naming provide guidance to data stewards and data contributors advance a clearer understanding of the information in the files, tables and fields via appropriate

Open-Source GIS  

SciTech Connect

The components making up an Open Source GIS are explained in this chapter. A map server (Sect. 30.1) can broadly be defined as a software platform for dynamically generating spatially referenced digital map products. The University of Minnesota MapServer (UMN Map Server) is one such system. Its basic features are visualization, overlay, and query. Section 30.2 names and explains many of the geospatial open source libraries, such as GDAL and OGR. The other libraries are FDO, JTS, GEOS, JCS, MetaCRS, and GPSBabel. The application examples include derived GIS-software and data format conversions. Quantum GIS, its origin and its applications explained in detail in Sect. 30.3. The features include a rich GUI, attribute tables, vector symbols, labeling, editing functions, projections, georeferencing, GPS support, analysis, and Web Map Server functionality. Future developments will address mobile applications, 3-D, and multithreading. The origins of PostgreSQL are outlined and PostGIS discussed in detail in Sect. 30.4. It extends PostgreSQL by implementing the Simple Feature standard. Section 30.5 details the most important open source licenses such as the GPL, the LGPL, the MIT License, and the BSD License, as well as the role of the Creative Commons.

Integrated mobile GIS and wireless internet map servers for environmental monitoring and management  

E-Print Network (OSTI)

ABSTRACT: With the progress of mobile GIS technology there is a great potential for adopting wireless communications and Internet mapping services for regional environmental management programs and natural habitat conservation. This paper provides an overview of a NASA-funded research project that focuses on the development of mobile GIS tools and wireless Internet Map Server (IMS) services to facilitate environmental monitoring and management tasks. By developing and testing wireless web-based map/image servers, mobile GIS applications, and global positional systems (GPS), this research created an integrated software/hardware infrastructure for a prototype mobile GIS application. The mobile GIS prototype allows multiple resource managers and park rangers to access large-size, remotely sensed images and GIS layers from a portable web server mounted in a vehicle. Users can conduct real-time spatial data updates and/or submit changes back to the web server over the wireless local area network (WLAN). This paper discusses in general the major components of mobile GIS, their current technological limitations, and potential problems during implementation. Key research agenda for mobile GIS are identified with suggestions for future research and development.

The problem of proposed topology for network comes when using Prim's algorithm with default distance (unrealistic distances) between network's nodes and don't care about the lakes, high hills, buildings, etc. This problem will cause incorrect estimations for cost (budget) of requirements like the media (optic fibre) and the number or type of Access-points, regenerator, Optic Amplifier, etc. This paper proposed a new technique of implementing Prim's algorithm to obtain realistic topology using realistic distances between network's nodes via Global Positioning System GPS and Geographic Information Systems GIS packages. Applying the new technique on academic institutes network of Erbil city from view of media (optic fibre) shows that there is disability in cost (budget) of the media which is needed (nearly) 4 times if implement default Prim's algorithm (don't using GPS & GIS) base on unrealistic distances between the nodes.

APPLICATIONS OF GIS IN COMMUNITY-BASED FOREST MANAGEMENT IN AUSTRALIA (AND NEPAL) By  

E-Print Network (OSTI)

Community forestry is now a popular approach in forest management globally. Although local communities have previously been involved in forest management in various minor ways, community-based forestry is very new in the Australian context. Because of the multiple interests of forest users and other community interest groups, a wider range of up-to-date information is being requested in community forestry, than has been used in conventional government-based forest management in the past. The overall aim of this research was to explore the potential and constraints for the application of Geographic Information System (GIS) technology in community forest management in Australia and to relate the results also to Nepal. Specific objectives were to: (i) review the applications of GIS in forestry and community forestry worldwide, (ii) determine stakeholders views on their requirements for the use of GIS in community-based forest management, (iii) prepare and demonstrate various practical applications of GIS requested by community groups in the Wombat State Forest, (iv) identify the strengths and limitations of GIS in community forestry, and (v) relate findings on GIS

Cementing horizontal wells  

SciTech Connect

Since the introduction of horizontal drilling, most completions have been open hole. Open-hole or slotted-liner completions may be satisfactory in straight, thick formations, if stimulation is not required. But if the wellbore wanders out of the reservoir, whether due to loss of directional control or spotty knowledge of formation dimensions, casing becomes a necessity. In addition, a wellbore that stays in the formation but comes uncomfortably close to the water-oil contact or gas cap requires casing to prevent coning. Further, if stimulation is anticipated, or may become a necessity, it is essential that the hole be cased and cemented. Otherwise, there is no control of the stimulation treatment. Even if the horizontal wellbore itself does not require casing, intermediate casing in the high-angle hole is needed. This is especially critical in open-hole completions below a gas cap, for example. The keys to effective horizontal cementing are fundamentally the same as for cementing vertical wells: proper centralization of casing in the bore-hole to ensure efficient mud removal and well-designed cement slurries.

Fundamentals of horizontal well completions  

Science Conference Proceedings (OSTI)

Oil and gas wells are drilled horizontally for a variety of reasons, chiefly to improve production without drilling multiple vertical wells and to prevent water or gas coning. Benefits of horizontal drilling are well documented. This article addresses the fundamentals of completing a horizontal well, discussing completion by (1) open hole, (2) casing packers, (3) slotted or perforated liner, and (4) cemented casing/liner. Completion methods 1 through 3 are generally known as ''drain hole'' completions, and method 4 is commonly called the ''case hole'' or ''stimulated'' completion.

Nuclear component horizontal seismic restraint  

DOE Patents (OSTI)

A nuclear component horizontal seismic restraint. Small gaps limit horizontal displacement of components during a seismic occurrence and therefore reduce dynamic loadings on the free lower end. The reactor vessel and reactor guard vessel use thicker section roll-forged rings welded between the vessel straight shell sections and the bottom hemispherical head sections. The inside of the reactor guard vessel ring forging contains local vertical dovetail slots and upper ledge pockets to mount and retain field fitted and installed blocks. As an option, the horizontal displacement of the reactor vessel core support cone can be limited by including shop fitted/installed local blocks in opposing alignment with the reactor vessel forged ring. Beams embedded in the wall of the reactor building protrude into apertures in the thermal insulation shell adjacent the reactor guard vessel ring and have motion limit blocks attached thereto to provide to a predetermined clearance between the blocks and reactor guard vessel ring.

Horizontal completions challenge for industry  

SciTech Connect

As the technology to drill horizontal wells continues to evolve, the problem of efficiently and cost-effectively completing such wells grows. The economics of applying horizontal technology in high-productivity reservoirs demands both increased production and lower development costs. Such high productivity reservoirs are typical of the Gulf of Mexico, North Sea, South China basin, and other areas. Lowering development costs is achieved by drilling fewer wells and in the offshore environment by reducing the number of platforms and other well structures. Specifically addressed in this article are the problems of achieving high efficiency, long lasting completions while controlling costs in unconsolidated and poorly consolidated sandstone reservoirs.

CyberGIS software: a synthetic review and integration roadmap  

Science Conference Proceedings (OSTI)

CyberGIS defined as cyberinfrastructure-based geographic information systems (GIS) has emerged as a new generation of GIS representing an important research direction for both cyberinfrastructure and geographic information science. This study introduces a 5-year effort funded by the US National Science Foundation to advance the science and applications of CyberGIS, particularly for enabling the analysis of big spatial data, computationally intensive spatial analysis and modeling (SAM), and collaborative geospatial problem-solving and decision-making, simultaneously conducted by a large number of users. Several fundamental research questions are raised and addressed while a set of CyberGIS challenges and opportunities are identified from scientific perspectives. The study reviews several key CyberGIS software tools that are used to elucidate a vision and roadmap for CyberGIS software research. The roadmap focuses on software integration and synthesis of cyberinfrastructure, GIS, and SAM by defining several key integration dimensions and strategies. CyberGIS, based on this holistic integration roadmap, exhibits the following key characteristics: high-performance and scalable, open and distributed, collaborative, service-oriented, user-centric, and community-driven. As a major result of the roadmap, two key CyberGIS modalities gateway and toolkit combined with a community-driven and participatory approach have laid a solid foundation to achieve scientific breakthroughs across many geospatial communities that would be otherwise impossible.

Introduction The European Commission INCO Copernicus project was promoted in autumn 2000 as "Sustainable management of the marine ecosystem and living resources of the White Sea". One of the scientific and technical objectives is t o create dedicated environmental, ecological and socio-economic databases integrated in a Geographical Information System (GIS) for the White Sea region. To ensure the access to the database development also in the future, the open source gis approach as GRASS5.0 was chosen [1]. Into the White Sea GRASS-GIS database the bathymetry data with resolution 1 by 0.5 minutes was used to model the bottom surface of the White Sea. Russian coordinate system of Pulkova 42 was used. DCW vector data were used for the shoreline and the White Sea was divided to 7 traditional geographic areas. Raster layer of the bathymetry was divided with vector polygons to appropriate geographic areas and the area and volume were calculated. The hydrological and chemical parameters as

An Approach to Integrate a Space-Time GIS Data Model with High Performance Computers  

Science Conference Proceedings (OSTI)

In this paper, we describe an approach to integrate a Space-Time GIS data model on a high performance computing platform. The Space-Time GIS data model has been developed on a desktop computing environment. We use the Space-Time GIS data model to generate GIS module, which organizes a series of remote sensing data. We are in the process of porting the GIS module into an HPC environment, in which the GIS modules handle large dataset directly via parallel file system. Although it is an ongoing project, authors hope this effort can inspire further discussions on the integration of GIS on high performance computing platforms.

Now we are in the age of 21th century. We have seen in last few decades that the progress of information technology with leaps and bounds, which have completely changed the way of life in the developed nations. While internet has changed the established working practice and opened new vistas and provided a platform to connect, this gives the opportunity for collaborative work space that goes beyond the global boundary. We are living in the global economy and India leading towards Liberalize Market Oriented Economy (LMOE). Considering this things, focusing on GIS, we proposed a system for collection of socio economic data and water resource management information of rural area via internet.

Developing a GIS-Based MCE Site Selection Tool in ArcGIS Using COM Technology IAJIT First Online Publication  

E-Print Network (OSTI)

Abstract: Site selection is a complex process for owners and analysts. This process involves not only technical requirements, but also economical, social, environmental and political demands that may result in conflicting objectives. Site selection is the process of finding locations that meet desired conditions set by the selection criteria. Geographic Information Systems (GIS) and Multi Criteria Evaluation techniques (MCE) are the two common tools employed to solve these problems. However, each suffers from serious shortcomings and could not be used alone to reach an optimum solution. This poses the challenge of integrating these tools. Developing and using GIS-based MCE tools for site selection is a complex process that needs well trained GIS developers and analysts who are not often available in most organizations. In this paper, a GIS-based Multicriteria Evaluation Site Selection Tool is developed in ArcGIS 9.3 using COM technology to achieve software interoperability. This tool can be used by engineers and planners with different levels of GIS and MCE knowledge to solve site selection problems.

Evaluating the Potential of Commercial GIS for Accelerator Configuration Management  

SciTech Connect

The Geographic Information System (GIS) is a tool used by industries needing to track information about spatially distributed assets. A water utility, for example, must know not only the precise location of each pipe and pump, but also the respective pressure rating and flow rate of each. In many ways, an accelerator such as CEBAF (Continuous Electron Beam Accelerator Facility) can be viewed as an ''electron utility''. Whereas the water utility uses pipes and pumps, the ''electron utility'' uses magnets and RF cavities. At Jefferson lab we are exploring the possibility of implementing ESRI's ArcGIS as the framework for building an all-encompassing accelerator configuration database that integrates location, configuration, maintenance, and connectivity details of all hardware and software. The possibilities of doing so are intriguing. From the GIS, software such as the model server could always extract the most-up-to-date layout information maintained by the Survey & Alignment for lattice modeling. The Mechanical Engineering department could use ArcGIS tools to generate CAD drawings of machine segments from the same database. Ultimately, the greatest benefit of the GIS implementation could be to liberate operators and engineers from the limitations of the current system-by-system view of machine configuration and allow a more integrated regional approach. The commercial GIS package provides a rich set of tools for database-connectivity, versioning, distributed editing, importing and exporting, and graphical analysis and querying, and therefore obviates the need for much custom development. However, formidable challenges to implementation exist and these challenges are not only technical and manpower issues, but also organizational ones. The GIS approach would crosscut organizational boundaries and require departments, which heretofore have had free reign to manage their own data, to cede some control and agree to a centralized framework.

Proper centralizers can improve horizontal well cementing  

SciTech Connect

The selection and spacing of appropriate centralizers can improve the cementation of high-angle and horizontal wells. Mud removal is one of the most important factors in obtaining a good cement job. Effective centralization assists in mud removal and helps ensure an even cement coat around the casing. Centralizers for horizontal wells have to fulfill two requirements: They should have a high restoring capability and a low moving force, and they should allow pipe rotation and reciprocation. Conventional bow-type centralizers have been used successfully in some horizontal wells. But as the horizontal section length increases, special centralizers, such as low-moving-force, bow-type centralizers and rigid centralizers, may be necessary. The paper describes the following: cementing liners, centralization, torque and drag, centralizer placement, the bow-type centralizer, the rigid centralizer, and the downhole activated centralizer.

Alaska Coal Geology: GIS Data | OpenEI  

Open Energy Info (EERE)

Coal Geology: GIS Data Coal Geology: GIS Data Dataset Summary Description Estimated Alaska coal resources are largely in Cretaceous and Tertiary rocks distributed in three major provinces. Northern Alaska-Slope, Central Alaska-Nenana, and Southern Alaska-Cook Inlet. Cretaceous resources, predominantly bituminous coal and lignite, are in the Northern Alaska-Slope coal province. Most of the Tertiary resources, mainly lignite to subbituminous coal with minor amounts of bituminous and semianthracite coals, are in the other two provinces. The combined measured, indicated, inferred, and hypothetical coal resources in the three areas are estimated to be 5,526 billion short tons (5,012 billion metric tons), which constitutes about 87 percent of Alaska's coal and surpasses the total coal resources of the conterminous United States by 40 percent.

Using GIS to Identify Remediation Areas in Landfills  

Science Conference Proceedings (OSTI)

This paper reports the use of GIS mapping softwareArcMap and ArcInfo Workstationby the Idaho National Engineering and Environmental Laboratory (INEEL) as a non-intrusive method of locating and characterizing radioactive waste in a 97-acre landfill to aid in planning cleanup efforts. The fine-scale techniques and methods used offer potential application for other burial sites for which hazards indicate a non-intrusive approach. By converting many boxes of paper shipping records in multiple formats into a relational database linked to spatial data, the INEEL has related the paper history to our current GIS technologies and spatial data layers. The wide breadth of GIS techniques and tools quickly display areas in need of remediation as well as evaluate methods of remediation for specific areas as the site characterization is better understood and early assumptions are refined.

Sand-control alternatives for horizontal wells  

SciTech Connect

This paper reports that it has been well documented that horizontal completions increase production rates, as much as two to five times those of conventional techniques, because more of the producing formation is exposed to the wellbore. Although productivity improvements are highly sensitive to reservoir parameters, it is becoming generally accepted that optimum horizontal lengths will be 2,000 to 4,000 ft. The length of these completions generally causes the velocity of the fluid at the sandface to be an order of magnitude less than that observed in conventional completions. Because drag forces contributed to sand production, horizontal wells can produce at higher sand-free flow rates than conventional completions in the same reservoir. While it is frequently argued that horizontal wells do not need sand control, the potential for sand production increases significantly as reserves deplete and rock stresses increase. This is becoming more evident today in several major North Sea oil fields with conventional completions. Also, many unconsolidated formations produce sand for the first time with the onset of water production, a typical problem in such areas as the Gulf of Mexico. Operators must decide whether to implement sand control in the original horizontal-completion program because of an immediate concern or because the potential exists for a problem to arise as the well matures.

(Purpose): Provide information on the solar resource potential for the data domain. The insolation values represent the average solar energy available to a concentrating collector, such as a dish collector, which tracks the sun continuously. (Supplemental Information): These data provide monthly average and annual average daily total solar resource averaged over surface cells of approximately 40 km by 40 km in size. The solar resource value is represented as watt-hours per square meter per day for each month. The data were developed from NREL's Climatological Solar Radiation (CSR) Model. This model uses information on cloud cover, atmospheric water vapor and trace gases, and the amount of aerosols in the atmosphere to calculate the monthly average daily total insolation (sun and sky) falling on a horizontal surface. Existing ground measurement stations are used to validate the data where possible. The modeled values are accurate to approximately 10% of a true measured value within the grid cell due to the uncertainties associated with meteorological input to

The Lab for Energy and Environment (LFEE) at MIT is developing a Geographic Information System (GIS) for carbon management. The GIS will store, integrate, and manipulate information relating to the components of carbon management systems. Additionally, the GIS can be used to interpret and analyze the effect of developing these systems. In the first year of this three year project, we focused on two tasks: (1) specifying the system design--defining in detail the GIS data requirements, the types of analyses that can be conducted, and the forms of output we will produce, as well as designing the computer architecture of the GIS and (2) creating the ''core'' datasets--identifying data sources and converting them into a form accessible by the GIS.

High accuracy diffuse horizontal irradiance measurements without a shadowband  

DOE Green Energy (OSTI)

The standard method for measuring diffuse horizontal irradiance uses a fixed shadowband to block direct solar radiation. This method requires a correction for the excess skylight blocked by the band, and this correction varies with sky conditions. Alternately, diffuse horizontal irradiance may be calculated from total horizontal and direct normal irradiance. This method is in error because of angular (cosine) response of the total horizontal pyranometer to direct beam irradiance. This paper describes an improved calculation of diffuse horizontal irradiance from total horizontal and direct normal irradiance using a predetermination of the angular response of the total horizontal pyranometer. We compare these diffuse horizontal irradiance calculations with measurements made with a shading-disk pyranometer that shields direct irradiance using a tracking disk. Results indicate significant improvement in most cases. Remaining disagreement most likely arises from undetected tracking errors and instrument leveling.

Portable top drive cuts horizontal drilling costs  

SciTech Connect

Economic analysis of a seven-well, long-reach horizontal drilling program into an unconsolidated, heavy-oil-bearing reservoir in Winter field near the Alberta/Saskatchewan border in Canada reveals that -- in the right application -- renting a portable top drive drilling system can reduce total drilling costs. Use of the portable top drive combined with other cost-saving measures enabled Saskoil, one of Canada`s larger independents, to drill more cheaply, on a cost-per-meter basis, in 1993 than in 1992. This was despite significant rental rates for drilling rigs and directional drilling services caused by increased demand in Western Canada. Total cost savings of 10% on wells that would otherwise cost in the (C) $500,000 range are believed realistic. Based on this year`s performance, Saskoil recommends top drive for the company`s future horizontal wells in this area. This article describes the operator`s horizontal well program, advantages of top drive in that program and how it was installed and applied. Estimated time savings for six wells, plus other ways top drive can cut costs and improve operations are discussed.

This paper presents a new hybrid learning algorithm for unsupervised classification tasks. We combined Fuzzy c-means learning algorithm and a supervised version of Minimerror to develop a hybrid incremental strategy allowing unsupervised classifications. We applied this new approach to a real-world database in order to know if the information contained in unlabeled features of a Geographic Information System (GIS), allows to well classify it. Finally, we compared our results to a classical supervised classification obtained by a multilayer perceptron.

DEVELOPMENT OF COAL BED METHANE UTILIZING GIS TECHNOLOGIES  

Science Conference Proceedings (OSTI)

During the second half of the 1990's, Coal Bed Methane (CBM) production increased dramatically nationwide to represent a significant new source of income and natural gas for many independent and established producers. Matching these soaring production rates during this period were the advancements in Geographical Information Systems (GIS) technologies generating terra-bytes of new data for the oil and gas industry. Coupled to these accelerating initiatives are many environmental concerns relating to production wastes and water table depletion of fresh water resources. It is these concerns that prompted a vital need within the industry for the development of Best Management Practices (BMPs) and mitigation strategies utilizing GIS technologies for efficient environmental protection in conjunction with effective production of CBM. This was accomplished by developing a framework to take advantage of a combination of investigative field research joined with leading edge GIS technologies for the creation of environmentally characterized regions of study. Once evaluated these regions had BMP's developed to address their unique situations for Coal Bed Methane production and environmental protection. Results of the project will be used to support the MBOGC's Programmatic Environmental Impact Statement as required by the Montana Environmental Policy Act (MEPA) and by the BLM for NEPA related issues for acreage having federally owned minerals.

GIS and plume dispersion modeling for population exposure assessment  

E-Print Network (OSTI)

The use of Pollutant Plume Dispersion Models is widespread in the evaluation of point sources of air pollution. These models provide valuable insight into the concentration and dispersion of hazardous materials throughout the atmosphere. Traditional methods of dispersion modeling for the permitting of new sources and the monitoring of existing sources have allowed much room for error in terms of the effect of the pollutants on nearby populations (Hardikar, 1995). The capabilities of GIS technology offer an improved method of conducting air quality modeling for permitting, remediation studies, and environmental monitoring. GIS has the ability to develop and manage a comprehensive database of model output, map layers, and demographic data that can prove extremely valuable in the modeling process. This data can serve to extend the capabilities of air pollution dispersion modeling from mere estimation of concentrations to comprehensive exposure assessment of neighboring populations (Lowry, et al. 1995, Maslia, et al. 1994). A study of the Monticello power plant in northeast Texas was conducted using the SCREEN3 mathematical plume dispersion model, US Census Bureau demographic data, and a GIS to examine the effects of the plant output on the people living in the seven county area surrounding the plant.

Application of GIS for Cassini Launch Support  

DOE Green Energy (OSTI)

The Cassini spacecraft began its eleven-year mission to Saturn on October 15, 1997. The spacecraft is powered by Radioisotope Thermoelectric Generators and Light Weight Radioisotope Heating Units comprised primarily of plutonium-238 as fuel. Due to the potential for a radiation release in the event of a launch accident, the US Department of Energy deployed a contingency response team to Cape Canaveral to support the National Aeronautics and Space Administration for the Cassini launch. The team was comprised of radiation monitoring and assessment teams, a communications/logistics team, and a team of Field Analysis System for Emergency Response (FASER) Geographic Information System personnel. FASER is a system developed around Arc/Info and Arcview for integrating and analyzing spatial information for nuclear emergency response activities. FASER operators integrated data from radiological prediction models, background radiation measurements, and a global positioning system-based Flight Path Recovery System for monitoring real-time aircraft locations. With this system, spatial data met the need to be processed and presented to mission managers quickly during the hours preceding launch.

E-Print Network (OSTI)

This contribution deals with the role of geographical information in participatory research concerning coastal zones and its potential to bridge the gap between research and coastal zone management. The study aims at modeling the interactions between human activities in a maritime basin. A dynamic GIS is used as a tool to facilitate the exchange of points of view and to share knowledge. Geographic information technologies are used at several levels: data collection, GIS analysis, mapping, and simulations. The results show that the GIS-based capture data is well managed by the stakeholders who are interested in contributing to the process of gathering scientific data. The results of a participatory workshop with stakeholders show that the dynamic component of the data adds a real value for management. The possibility to use such a dynamic GIS to discuss and simulate management scenarios is tested, but it needs to be built up gradually.

Purpose: Provide information on the solar resource potential for Alaska. The insolation values represent the average solar energy available to a flat plate collector, such as a photovoltaic panel, oriented due south at an angle from horizontal equal to the latitude of the collector location. Supplemental_Information: This data provides monthly average and annual average daily total solar resource averaged over surface cells of approximatley 40 km by 40 km in size. This data was developed from the Climatological Solar Radiation (CSR) Model. The CSR model was developed by the National Renewable Energy Laboratory for the U.S. Department of Energy. Specific information about this model can be found in Maxwell, George and Wilcox (1998) and George and Maxwell (1999). This model uses information on cloud cover, atmostpheric water vapor and trace gases, and the amount of aerosols in the atmosphere to calculate the monthly average daily total insolation (sun and sky) falling on a horizontal surface. The cloud cover data used as input to the CSR model are an 7-year histogram (1985-1991) of monthly average cloud fraction provided for grid cells of approximately 40km x 40km in size. Thus, the spatial resolution of the CSR model output is defined by this database. The data are obtained from the National Climatic Data Center in Ashville, North Carolina, and were developed from the U.S. Air Force Real Time Nephanalysis (RTNEPH) program. Atmospheric water vapor, trace gases, and aerosols are derived from a variety of sources. The procedures for converting the collector at latitude tilt are described in Marion and Wilcox (1994). Where possible, existing ground measurement stations are used to validate the data. Nevertheless, there is uncertainty associated with the meterological input to the model, since some of the input parameters are not avalible at a 40km resolution. As a result, it is believed that the modeled values are accurate to approximately 10% of a true measured value within the grid cell. Due to terrain effects and other micoclimate influences, the local cloud cover can vary significantly even within a single grid cell. Furthermore, the uncertainty of the modeled estimates increase with distance from reliable measurement sources and with the complexity of the terrain.

GIS-based land-use suitability analysis: a critical overview  

E-Print Network (OSTI)

There are three main objectives of this monograph: (i) to provide an introduction to geographical information technology along with an historical perspective on the evolving role of Geographic Information Systems (GIS) in planning, (ii) to overview relevant methods and techniques for GISbased land-use suitability mapping and modeling, and (iii) to identify the trends, challenges and prospects of GIS-based land-use suitability analysis. The monograph focuses on two perspectives of GIS-based land-use suitability analysis: the techno-positivist perspective and the socio-political, public participation perspectives. It is organized into six chapters. After an introductory setting chapter, which defines the scope of land-use suitability analysis, an overview of relevant GIS technology is provided in Chapter 2. Chapter 3 offers an historical account of the development of GIS. It also discusses the development of GIS in the context of evolving perspectives of planning. Chapter 4 gives an overview of the methods for GIS-based land-use suitability modeling. The overview provides a background against which selected case studies are discussed in Chapter 5. The concluding chapter summarized the main points of the monographs and discusses problems and prospects for GIS-based land-use suitability analysis.

Geotechnical Seismic Hazard Evaluation At Sellano (Umbria, Italy) Using The GIS Technique  

Science Conference Proceedings (OSTI)

A tool that has been widely-used in civil engineering in recent years is the geographic information system (GIS). Geographic Information systems (GIS) are powerful tools for organizing, analyzing, and presenting spatial data. The GIS can be used by geotechnical engineers to aid preliminary assessment through to the final geotechnical design. The aim of this work is to provide some indications for the use of the GIS technique in the field of seismic geotechnical engineering, particularly as regards the problems of seismic hazard zonation maps. The study area is the village of Sellano located in the Umbrian Apennines in central Italy, about 45 km east of Perugia and 120 km north-east of Rome The increasing importance attributed to microzonation derives from the spatial variability of ground motion due to particular local conditions. The use of GIS tools can lead to an early identification of potential barriers to project completion during the design process that may help avoid later costly redesign.

Using ISC & GIS to predict sulfur deposition from coal-fired power plants  

E-Print Network (OSTI)

The goal of this research project was to determine if atmospheric sources have the potential of contributing significantly to the sulfur content of grazed forage. Sulfur deposition resulting from sulfur dioxide emissions from coal- fired power plants was predicted utilizing the Industrial Source Complex Long-Term (ISCLT2) Model for the areas ofa interest in East Texas. GRASS, a geographical information system (GIS), was used to pull together all predicted values from ISCLT2 and present them in the form of predicted sulfur deposition maps with different ranges of deposition. Two field trips to NE Texas were taken to obtain data on soil and forage sulfur content. GRASS was used extensively in the planning process before each trip and the global positioning system was also used extensively during the trip to locate sampling sites and to obtain the geographical location of each site. The methodology developed predicts that 11 to 21 kg sulfur/ha per year can be deposited as far as 100 to 160 km from the source. Data from both field trips do not show a statistical significant relation between predicted sulfur deposition and either soil or forage sulfur content. However, the data do show that there is a trend of increasing soil and forage sulfur content as predicted sulfur deposition increases.

Science Conference Proceedings (OSTI)

This paper presents a GIS-based 1-d distributed overland flow model and summarizes an application to simulate a flood event. The model estimates infiltration using the Green-Ampt approach and routes excess rainfall using the 1-d diffusive wave approximation. The model was designed to use readily available topographic, soils, and land use/land cover data and rainfall predictions from a meteorological model. An assessment of model performance was performed for a small catchment and a large watershed, both in urban environments. Simulated runoff hydrographs were compared to observations for a selected set of validation events. Results confirmed the model provides reasonable predictions in a short period of time.

College Students GIS Spatial Concept Knowledge Assessed by Concept Maps  

E-Print Network (OSTI)

The development of spatial thinking proficiency has been increasingly demanded in Geographic Information System (GIS) education. Despite this educational trend, there is little empirical research on college students' spatial concept knowledge, which critically affects the quality of spatial thinking. This study addressed the following three research questions: 1) What differences exist between students' understandings of spatial concepts at the beginning, middle, and end of an introductory-level GIS course?, 2) What spatial misconceptions students may possess while taking an introductory-level GIS course?, and 3) Which spatial concepts are easy or hard for undergraduate students to understand? The researcher asked twelve participants who were taking an introductory-level GIS course to create concept maps about space and revised their concept maps in three experiment sessions. For the first question, the researcher scored the sixty obtained concept maps and statistically analyzed those scores to examine if there is any significant difference among the scores of the three experiment sessions. For the second question, the researcher examined participants' misconceptions by analyzing the incorrect statements of distortion, map projection, and scale. For the third question, the researcher statistically analyzed concept-based scores to examine if there is any significant difference among the scores of three different complexity levels. A main finding for the first question was that there was a significant difference among the scores of the concept maps created in the first session and the scores of the concept maps revised in the second and third sessions. This implied that participants could successfully revise their own original concept maps in the middle of a semester. The result of the study of the second question indicated that a half of participants misunderstood the concepts of map projections and scale. This result suggested that some undergraduate students may have difficulty shifting from scientifically inappropriate spatial concept knowledge to appropriate knowledge. Analysis of the third question resulted that the concept-based scores of simple spatial concepts are significantly higher than the scores of complicated spatial concepts. This result inferred that participants' scores decreased as the complexity of the concepts increased.

Horizontal flow drilling requires focus on well control  

Science Conference Proceedings (OSTI)

Horizontal wells drilled underbalanced or while flowing must have surface equipment and a blow-out preventer stack specially designed for circulating operations. Functional well control methods for drilling horizontal wells have been developed in specific regions worldwide. Special safety equipment and procedures, however, are still required in most horizontal development applications. The challenge for horizontal drilling development and underbalanced drilling is to overcome the obstacles of government regulation, reduce pollution dangers, and improve personnel and equipment safety. Well control techniques tailored to the demands of each field can help overcome these challenges. Several well control elements must be addressed carefully on each horizontal well: drilling fluid requirements, well control procedures and equipment, and surface equipment and special considerations for handling hydrocarbons produced while drilling. The paper discusses each of these elements for underbalanced horizontal drilling.

Measurements of sky luminance, sky illuminance, and horizontal solar radiation  

Science Conference Proceedings (OSTI)

This paper presents initial findings of a sky measurement program currently in progress at the National Bureau of Standards. Measurements are reported on sky luminance and illuminance and how they relate to horizontal solar radiation and sun position. Correlations are presented relating horizontal illuminance to horizontal solar radiation, and zenith luminance to solar altitude. These empirical models are particularly suitable for use in daylighting energy studies since they are based on existing solar data currently available on standard weather tapes.

Horizontal, Anomalous U(1) Symmetry for the More Minimal Supersymmetric Standard Model  

E-Print Network (OSTI)

We construct explicit examples with a horizontal, ``anomalous'' $U(1)$ gauge group, which, in a supersymmetric extension of the standard model, reproduce qualitative features of the fermion spectrum and CKM matrix, and suppress FCNC and proton decay rates without the imposition of global symmetries. We review the motivation for such ``more'' minimal supersymmetric standard models and their predictions for the sparticle spectrum. There is a mass hierarchy in the scalar sector which is the inverse of the fermion mass hierarchy. We show in detail why DeltaS = 2 FCNC are suppressed when compared with naive estimates for nondegenerate squarks.

GIS-BASED PREDICTION OF HURRICANE FLOOD INUNDATION  

Science Conference Proceedings (OSTI)

A simulation environment is being developed for the prediction and analysis of the inundation consequences for infrastructure systems from extreme flood events. This decision support architecture includes a GIS-based environment for model input development, simulation integration tools for meteorological, hydrologic, and infrastructure system models and damage assessment tools for infrastructure systems. The GIS-based environment processes digital elevation models (30-m from the USGS), land use/cover (30-m NLCD), stream networks from the National Hydrography Dataset (NHD) and soils data from the NRCS (STATSGO) to create stream network, subbasins, and cross-section shapefiles for drainage basins selected for analysis. Rainfall predictions are made by a numerical weather model and ingested in gridded format into the simulation environment. Runoff hydrographs are estimated using Green-Ampt infiltration excess runoff prediction and a 1D diffusive wave overland flow routing approach. The hydrographs are fed into the stream network and integrated in a dynamic wave routing module using the EPA's Storm Water Management Model (SWMM) to predict flood depth. The flood depths are then transformed into inundation maps and exported for damage assessment. Hydrologic/hydraulic results are presented for Tropical Storm Allison.

GIS Symbology for FRMAC/CMHT Radiological/Nuclear Products  

SciTech Connect

This document is intended to codify, to the extent currently possible, the representation of map products produced for and by the Federal Radiological Monitoring and Assessment Center (FRMAC) and the Consequence Management Home Team (CHMT), particularly those that include model products from the National Atmospheric Release Advisory Capability (NARAC). This is to facilitate consistency between GIS products produced by different members of these teams, which should ease the task of interpreting these products by both team members and those outside the team who may need to use these products during a response. The aspects of symbology being considered are primarily isopleths levels (breakpoints) and colors used to plot NARAC modeled dose or deposition fields on mpas, although some comments will be made about the handling of legend and supporting textual information. Other aspects of symbolizing such products (e.g., transparency) are being left to the individual team members to allow them to adapt to particular organizational needs or requirements that develop during a particular a response or exercise. This document has been written in coordination with the creation of training material in Baskett, et al., 2008. It is not intended as an aid to NARAC product interpretation but to facilitate the work of GIS specialists who deal with these products in map design and in the development of supporting scripts and software that partially or completely automate the integration of NARAC model products with other GIS data. This work was completed as part of the NA-42 Technical Integration Project on GIS Automated Data Processing and Map Production in FY 2008. Other efforts that are part of this work include (a) updating the NARAC shapefile product representation to facilitate the automation work proceed at RSL as part of the same TI effort and (b) to ensure that the NARAC shapefile construct includes all of the necessary legend and other textual data to interpret dispersion and deposition patterns and related products correctly. This document is focusing on the products produced by the GIS Division of the Remove Sensing Laboratory (RSL) and by the National Atmospheric Release Advisory Center (NARAC), both separately and in combination. The expectation is that standard products produced by either group independently or in combination should use the same key attributes in displaying the same kinds of data so that products of a given type generally look similar in key aspects of the presentation, thereby minimizing any confusion of users when a variety of products from these groups may be needed. This document is dealing with the set of common standard products used in responding to radiological/nuclear releases. There are a number of less standard products that are used occasionally or in certain specific situations that are not addressed here. This includes special products that are occasionally produced by both NARAC and RSL in responses and major exercises to meet immediate and unanticipated requirements. At some future time, it may be appropriate to review the handling of such special products by both organizations to determine if there are any areas that would benefit from being integrated with the conventions described here. A particular area that should be addressed in the near-term is that of Derived Response Levels (DRLs) calculated by the Consequence Management Home Team (CMHT) or FRMAC Assessment Scientists. A new calculation is done for every event assigning contour levels, or break-points, based upon field measurements. These contour levels can be applied to deposition or dose rate NARAC calculations. Because these calculations are different every time, they can not be stored in a database.

Method and application of horizontal slice volumetrics to waterflood management and horizontal drilling  

SciTech Connect

A computer mapping program was used to make horizontal slices of pore volume. The goal was to create maps that showed the distribution of pore volume vertically and laterally throughout the reservoir. That information was used for studying waterflood feasibility, monitoring an existing waterflood, and planning a horizontal well. This work was done at the United States Naval Petroleum Reserve No. 1, Elk Hills, CA. The reservoirs are the Miocene aged Northwest Stevens A sands and T N sands. These sands are a series of stacked deep water turbidites draped across the western nose of a plunging anticline. To determine the reservoir sensitivity to the approach used to calculate horizontal slice volume, two methods were tested. The first involves creation of four isochores, bounded above by the sand top or base and below by the slice top or base, whose volumes are combined to give the slice volume. The second involves creation of a grid of the slice itself from which slice volume is calculated.

Demonstration of a utility industry horizontal drilling system: Horizontal well AMH-5 installation report  

SciTech Connect

The Department of Energy`s Office of Technology Development initiated an integrated demonstration of innovative technologies and systems for cleanup of VOCs in soils and groundwater at the Savannah River Site (SRS) in 1989. The overall goal of the program is demonstration of multiple technologies and systems in the fields of drilling, characterization, monitoring, and remediation at a single test bed. Innovative technologies are compared to one another and to baseline technologies in terms of technical performance and cost effectiveness. Transfer of successfully demonstrated technologies and systems to DOE environmental restoration organizations, to other government agencies, and to industry is a critical part of the program. Directional drilling has been shown to be a successful technique for enhancing access to the subsurface, thus improving remediation systems, especially remediation systems which perform in situ. Demonstration of an innovative directional drilling system at the Integrated Demonstration Site at the SRS, was initiated in June of 1992. The directional drilling system was designed to install an in situ remediation system. The drilling system is an experimental compaction/dry drilling technique developed by Charles Machine Works (Ditch Witch{reg_sign}) of Perry, Oklahoma. A horizontal well was installed in the M Area of the SRS below and parallel to an abandoned tile process sewer line. The installation of the horizontal well was a two-part process. Part one consisted of drilling the borehole, and part two was the horizontal well completion.

Application of horizontal wells in steeply dipping reservoirs  

E-Print Network (OSTI)

A three-dimensional reservoir simulation study is performed to evaluate the impact of horizontal well applications on oil recovery from steeply dipping reservoirs. The Provincia field, located in Colombia, provided the basic reservoir information for the study. Reservoir simulation results indicate that for reservoir dip angles greater than about 40', this parameter has little or no effect on the primary recovery performance for homogeneous high-permeability reservoirs, The initial gascap size and the anisotropy of permeability (kv/kh ratio) are the dominant parameters affecting the oil recovery. For thin reservoirs, the location of the horizontal injector will not significantly affect the oil recovery. Simultaneous gas and water injection through horizontal wells can increase the oil recovery factor from almost 35% under primary production to 40%. A significant incremental oil recovery could be expected by employing horizontal wells for simultaneous gas and water injection. A comparison of the production performance of horizontal and vertical producers shows that a horizontal well can produce oil up to 2.5 times the oil rate of a vertical well, without a high rate of gas production. Also, the use of horizontal producers significantly accelerates the oil recovery. For the case of a homogeneous reservoir under simultaneous gas and water injection, the horizontal well system does not give a significant increment in the oil recovery compared to the vertical well system.

Steerable vertical to horizontal energy transducer for mobile robots  

DOE Patents (OSTI)

The present invention provides a steerable vertical to horizontal energy transducer for mobile robots that less complex and requires less power than two degree of freedom tilt mechanisms. The present invention comprises an end effector that, when mounted with a hopping actuator, translates along axis (typically vertical) actuation into combined vertical and horizontal motion. The end effector, or foot, mounts with an end of the actuator that moves toward the support surface (typically a floor or the earth). The foot is shaped so that the first contact with the support surface is off the axis of the actuator. Off-axis contact with the support surface generates an on-axis force (typically resulting in vertical motion) and a moment orthogonal to the axis. The moment initiates a horizontal tumbling motion, and tilts the actuator so that its axis is oriented with a horizontal component and continued actuation generates both vertical and horizontal force.

Yaw dynamics of horizontal axis wind turbines  

DOE Green Energy (OSTI)

Designers of a horizontal axis wind turbine yaw mechanism are faced with a difficult decision. They know that if they elect to use a yaw- controlled rotor then the system will suffer increased initial cost and increased inherent maintenance and reliability problems. On the other hand, if they elect to allow the rotor to freely yaw they known they will have to account for unknown and random, though bounded, yaw rates. They will have a higher-risk design to trade-off against the potential for cost savings and reliability improvement. The risk of a yaw-free system could be minimized if methods were available for analyzing and understanding yaw behavior. The complexity of yaw behavior has, until recently, discouraged engineers from developing a complete yaw analysis method. The objectives of this work are to (1) provide a fundamental understanding of free-yaw mechanics and the design concepts most effective at eliminating yaw problems, and (2) provide tested design tools and guidelines for use by free-yaw wind systems manufacturers. The emphasis is on developing practical and sufficiently accurate design methods.

U.S. Regional Demand Forecasts Using NEMS and GIS  

SciTech Connect

The National Energy Modeling System (NEMS) is a multi-sector, integrated model of the U.S. energy system put out by the Department of Energy's Energy Information Administration. NEMS is used to produce the annual 20-year forecast of U.S. energy use aggregated to the nine-region census division level. The research objective was to disaggregate this regional energy forecast to the county level for select forecast years, for use in a more detailed and accurate regional analysis of energy usage across the U.S. The process of disaggregation using a geographic information system (GIS) was researched and a model was created utilizing available population forecasts and climate zone data. The model's primary purpose was to generate an energy demand forecast with greater spatial resolution than what is currently produced by NEMS, and to produce a flexible model that can be used repeatedly as an add-on to NEMS in which detailed analysis can be executed exogenously with results fed back into the NEMS data flow. The methods developed were then applied to the study data to obtain residential and commercial electricity demand forecasts. The model was subjected to comparative and statistical testing to assess predictive accuracy. Forecasts using this model were robust and accurate in slow-growing, temperate regions such as the Midwest and Mountain regions. Interestingly, however, the model performed with less accuracy in the Pacific and Northwest regions of the country where population growth was more active. In the future more refined methods will be necessary to improve the accuracy of these forecasts. The disaggregation method was written into a flexible tool within the ArcGIS environment which enables the user to output the results in five year intervals over the period 2000-2025. In addition, the outputs of this tool were used to develop a time-series simulation showing the temporal changes in electricity forecasts in terms of absolute, per capita, and density of demand.

Integrating GIS with Distributed Applications Using Dynamic Data-Sharing Mechanisms  

Science Conference Proceedings (OSTI)

Effective integration of a stand-alone GIS (e.g., ArcView 3.x) into a complex distributed software application requires an efficient, reliable mechanism for passing data and function requests to and from the GIS component. This paper describes the use of dynamic data-sharing and inter-process communication mechanisms to integrate GIS capability into a multi-jurisdictional distributed emergency management information system. These mechanisms include dynamic layer updates from spatial and attribute information shared via a distributed relational database across multiple sites; storage of private and shared ViewMarks to facilitate consistent GIS views; and asynchronous inter-process communication using function queuing and a data sharing library.

In Northwest Germany, Mobil Erdgas-Erdoel GmbH drilled, cased, and fraced the world`s deepest horizontal well in the ultra-tight Rotliegendes ``Main`` sand at 15,687 ft (4,783 m) true vertical depth. The multiple frac concept provides a cost-efficient method to economically produce significant gas resources in the ultra-tight Rotliegendes ``Main`` sand. Besides the satisfactory initial gas production rate, the well established several world records, including deepest horizontal well with multiple fracs, and proved this new technique to develop ultra-tight sands.

SATURATED-SUBCOOLED STRATIFIED FLOW IN HORIZONTAL PIPES  

Science Conference Proceedings (OSTI)

Advanced light water reactor systems are designed to use passive emergency core cooling systems with horizontal pipes that provide highly subcooled water from water storage tanks or passive heat exchangers to the reactor vessel core under accident conditions. Because passive systems are driven by density gradients, the horizontal pipes often do not flow full and thus have a free surface that is exposed to saturated steam and stratified flow is present.

U.S. Regional Demand Forecasts Using NEMS and GIS  

SciTech Connect

The National Energy Modeling System (NEMS) is a multi-sector, integrated model of the U.S. energy system put out by the Department of Energy's Energy Information Administration. NEMS is used to produce the annual 20-year forecast of U.S. energy use aggregated to the nine-region census division level. The research objective was to disaggregate this regional energy forecast to the county level for select forecast years, for use in a more detailed and accurate regional analysis of energy usage across the U.S. The process of disaggregation using a geographic information system (GIS) was researched and a model was created utilizing available population forecasts and climate zone data. The model's primary purpose was to generate an energy demand forecast with greater spatial resolution than what is currently produced by NEMS, and to produce a flexible model that can be used repeatedly as an add-on to NEMS in which detailed analysis can be executed exogenously with results fed back into the NEMS data flow. The methods developed were then applied to the study data to obtain residential and commercial electricity demand forecasts. The model was subjected to comparative and statistical testing to assess predictive accuracy. Forecasts using this model were robust and accurate in slow-growing, temperate regions such as the Midwest and Mountain regions. Interestingly, however, the model performed with less accuracy in the Pacific and Northwest regions of the country where population growth was more active. In the future more refined methods will be necessary to improve the accuracy of these forecasts. The disaggregation method was written into a flexible tool within the ArcGIS environment which enables the user to output the results in five year intervals over the period 2000-2025. In addition, the outputs of this tool were used to develop a time-series simulation showing the temporal changes in electricity forecasts in terms of absolute, per capita, and density of demand.

Knowledge-based modeling using GIS: nonpoint source pollution application  

E-Print Network (OSTI)

The concept of visualization in hydrologic modeling is discussed. A concept for integrating a knowledge-based system for analyzing simulation results is introduced. Visualization and expert, computer-based analysis when combined together produces a powerful tool for spatial data analysis and decision support. An application of such an integrated system in the context of nonpoint source (NPS) pollution control has been discussed to demonstrate these concepts. After a simulated implementation of the BMP recommendations, about 40 percent of the reduction in the area contributing above threshold limits (5 t/ac/yr) while 60 percent reduction in terms of volume of soil was observed over the watershed, for given rainfall conditions. The system provides an unique opportunity to evaluate and visualize the effects of alternative management practices used for erosion control. It was found that with appropriate land management, about at least a 40 percent reduction in the area exceeding the threshold can be obtained for rainfall ranging from 0.5 to 5 inches. A methodology for addressing nutrient management has been developed as well. Although the domain specific nature of the system limits the alternatives assessed, the system addresses the need for GIS based data analysis and interpretation, and also generates an optimum best management practices (BMPS) map for NPS pollution control.

Geographic Information System (GIS) Emergency Support for the May 2000 Cerro Grande Wildfire, Los Alamos, New Mexico, USA  

Science Conference Proceedings (OSTI)

In May 2000 the Cerro Grande wildfire swept through Los Alamos, New Mexico, burning approximately 17,400 ha (43,000 acres) and causing evacuation of Los Alamos National Laboratory (LANL) and the communities of Los Alamos and White Rock. An integral part of emergency response during the fire was the use of geographic information system (GIS) technology, which continues to be used in support of post-fire restoration and environmental monitoring. During the fire Laboratory GIS staff and volunteers from other organizations worked to produce maps and provide support for emergency managers, including at an emergency GIS facility in Santa Fe. Subsequent to the fire, Laboratory GIS teams supported the multiagency Burned Area Emergency Rehabilitation (BAER) team to provide GIS data and maps for planning mitigation efforts. The GIS teams continue to help researchers, operations personnel, and managers deal with the tremendous changes caused by the fire. Much of the work is under the auspices of the Cerro Grande Rehabilitation Project (CGRP) to promote recovery from fire damage, improve information exchange, enhance emergency management, and conduct mitigation activities. GIS efforts during the fire provided important lessons about institutional matters, working relationships, and emergency preparedness. These lessons include the importance of (1) an integrated framework for assessing natural and human hazards in a landscape context; (2) a strong GIS capability for emergency response; (3) coordinated emergency plans for GIS operations; (4) a method for employees to report their whereabouts and receive authoritative information during an evacuation; (5) GIS data that are complete, backed-up, and available during an emergency; (6) adaptation of GIS to the circumstances of the emergency; (7) better coordination in the GIS community; (8) better integration of GIS into LANL operations; and (9) a central data warehouse for data and metadata. These lessons are important for planning future directions of GIS at LANL. Growing maturity of GIS is expected to lead to standardization and a better-integrated, more-coordinated approach to data sharing and emergency management at LANL, and within DOE, in accord with the federal government's increasing focus on electronic communication for its organizational and public interactions.

The paper highlights the importance of police departments identifying the thematic mapping creating for the rural crime areas. The Geographical Information system (GIS) also using for the how to we create for the crime maps and which mode we are giving the solution for the society or environment. GIS can be used as a tool to identify factors contributing to crime, and thus allow police to proactively respond to the situations before they become problematic. Generally, GIS includes data transfer, geocoding, data integration, system customization, and confidentiality issues are discussed in detail. Finally, we have illustrated the temporal crime incidences also implementing for the GIS analysis. This article will explore the use and possibilities of GIS by Indian Police in describing and analyzing crime action.

Exploring Volunteered Geographic Information (VGI) for Emergency Management: Toward a Wiki GIS Framework  

E-Print Network (OSTI)

The past three years have witnessed unprecedented growth of user-generated volunteered geographic information (VGI) on the Web. Although scholars, decision makers, and citizens have recognized the potential value of VGI in emergency management, there exists no rigorous study on the availability, quality, and feasibility of VGI for applications related to emergency management. This dissertation applies methodologies of GIScience and computer science to present an overview of VGI and explore its value in emergency management with the goal of developing a wiki GIS approach for community emergency preparedness. This dissertation research concludes that VGI and wiki GIS represent new development in public participation in the production and use of geographic information. In emergency management, VGI and wiki GIS suggest a new approach to incorporate the general public in emergency response activities. By incorporating VGI in emergency management, official agencies and the general public gain better situational awareness in emergency management.

Contrast between the vertical and horizontal mercury discharge lamps  

SciTech Connect

This paper discusses the thermal behavior of a high pressure mercury lamp in a horizontal position, compared with that of a vertical lamp. The model adopted is three-dimensional, steady, and powered DC. After the model validation, we analyzed temperature fields and velocities for the case of the lamp in a horizontal position by comparing it with those of a lamp in vertical position. This setting initially fixed the wall temperature equal to 1000 K. However, the morphology of the temperature profile in the case of the horizontal lamp indicates that the temperature of the wall cannot be uniform. Thus, we have, in a second time, performed an energy balance at the wall to calculate its temperature. This aims to understand the influence of convection on the thermal properties of the source.

Development of an ArcGIS-pollutant load application (PLOAD) tool  

E-Print Network (OSTI)

Many of the findings of previous studies have indicated that there is a direct correlation between water quality and urbanization. Increasing impervious coverage typically results in a decrease in water quality. The purpose of this study was to adapt an automated tool for assessing the Pollutant Load Application (PLOAD). Created by CH2M HILL, a fullservice engineering and construction enterprise, PLOAD is a simplified GIS-based model used to calculate pollutants within a watershed. The so-called simple method implemented by PLOAD and discussed in this thesis has been endorsed by the EPA as a viable screening tool for National Pollutant Discharge Elimination System (NPDES) stormwater projects. This model was designed to be used with ArcView 3.3. ArcView 3.3 is a depreciated product, the capabilities of which have been replaced by ArcGIS 9.1. Using the same GIS data and tabular data required by PLOAD and custom ArcObjects scripting, a replacement, ArcGIS-PLOAD, was created. The current version of ArcGISPLOAD implements the simple method to calculate total pollutant load in pounds per year based on basin boundaries, precipitation in inches per year, ratio of storms producing runoff, parcel land use and parcel area, runoff coefficient for each land use, event mean pollutant concentrations for each land use. Time comparisons between the original PLOAD and the new ArcGIS-PLOAD revealed significant improvements. Both versions of PLOAD produce an intersection between the basin boundary and the land use layer. Calculations are actually done to the intersect layer. It was also found that the original PLOAD disregarded an albeit small portion of the intersection polygons. The new version does not. With the creation of ArcGIS-PLOAD, it is anticipated that it will become a small step in assist the State of Texas in improving water quality.

Application Study of a Single House Horizontal Heating System  

E-Print Network (OSTI)

It is imperative to get new heating systems into the market and implement rate structures with heat meters for the purpose of energy conservation and environmental protection. Based on analysis of current heating technology, this paper analyzes the different forms of heating systems suited for single household metering. We introduce especially the single house horizontal spanning system and show how to select the heat flow rate of the radiator. We also study the distribution rule of the heat intermedium of horizontal heating system. To simplify the workload of engineering process and make the design more accurate, a new method for calculating the average temperature of the intermedium and the heat flow rate of this heating system is put forward. Comparison is also made between the system in question and the heating system in series. A few important questions are raised and discussed, such as the computation of combining different forms of radiators, the verification of the pipe radiation, the end of the radiator without spanning pipe, and the selection of the pipe diameter. At the same time, we study the influence of the horizontal heating system on the whole heating network, describe the characteristics of a single household horizontal heating system and the importance of its hydraulic computation, and analyze the influence of the gravitational head to this heating system. We also study the hydraulic condition of the single house horizontal system and the relationship of each party under the adjustment. In addition, the operation of single household horizontal heating system is verified in a real project, and its reliability is testified. This paper provides a method for further research on related issues of a single household metering heating system and is valuable for design, operation and management.

Using GIS technology to manage information following a bio-terrorism attack.  

Science Conference Proceedings (OSTI)

The BROOM system was developed to collect, manage and analyze information from bioterrorist attacks on strategic buildings. GIS features help decision-makers and analysts rapidly assess the current status of contaminated facilities and develop optimized cleanup strategies. BROOM consists of networked server, desktop and PDA components. PDAs are deployed to collect samples of suspected bioagents, such as anthrax. Novel geostatistical methods are used to generate contaminant maps and define optimum locations for subsequent sampling. Efficiency and accuracy gains witnessed in field tests show that GIS technology can play a vital role in visualizing, managing and analyzing data from bioterrorism incidents.

NREL GIS Data: Hawaii High Resolution Photovoltaic | OpenEI  

Open Energy Info (EERE)

Photovoltaic Photovoltaic Dataset Summary Description Abstract - Monthly and annual average solar resource potential for the State of Hawaii. Purpose - Provide information on the solar resource potential for Hawaii. The insolation values represent the average solar energy available to a flat plate collector, such as a photovoltaic panel, oriented due south at an angle from horizontal equal to the latitude of the collector location. Supplemental Info - This data provides monthly average and annual average daily total solar resource averaged over surface cells of 0.1 degrees in both latitude and longitude, or about 10 km in size. This data was developed using the State University of New York/Albany satellite radiation model. This model was developed by Dr. Richard Perez and collaborators at the National Renewable Energy Laboratory and other universities for the U.S. Department of Energy. Specific information about this model can be found in Perez, et al. (2002). This model uses hourly radiance images from geostationary weather satellites, daily snow cover data, and monthly averages of atmospheric water vapor, trace gases, and the amount of aerosols in the atmosphere to calculate the hourly total insolation (sun and sky) falling on a horizontal surface. Atmospheric water vapor, trace gases, and aerosols are derived from a variety of sources. The procedures for converting the collector at latitude tilt are described in Marion and Wilcox (1994). Where possible, existing ground measurement stations are used to validate the data. Nevertheless, there is uncertainty associated with the meterological input to the model, since some of the input parameters are not avalable at a 10km resolution. As a result, it is believed that the modeled values are accurate to approximately 10% of a true measured value within the grid cell. Due to terrain effects and other micoclimate influences, the local cloud cover can vary significantly even within a single grid cell. Furthermore, the uncertainty of the modeled estimates increase with distance from reliable measurement sources and with the complexity of the terrain.

Direct Solution Of The Implicit Formulation Of Fourth Order Horizontal Diffusion For Gridpoint Models On The Sphere  

E-Print Network (OSTI)

High order horizontal diffusion of the form Kr 2m is widely used in spectral models as a means of preventing energy accumulation at the shortest resolved scales. In the spectral context, an implicit formulation of such diffusion is trivial to implement. The present note describes an efficient method of implementing implicit high order diffusion in global finite difference models. The method expresses the high order diffusion equation as a sequence of equations involving r 2 . The solution is obtained by combining fast Fourier transforms in longitude with a finite difference solver for the second order ordinary differential equation in latitude. The implicit diffusion routine is suitable for use in any finite difference global model that uses a regular latitude/longitude grid. The absence of a restriction on the timestep makes it particularly suitable for use in semi-Lagrangian models. The scale selectivity of the high order diffusion gives it an advantage over the uncent...

Study of a Fault Analysis System for a Heat Supply Network Based on GIS  

E-Print Network (OSTI)

Conventional methods cannot satisfy the request of the layout and operation management in a heating system. The geographical information system (GIS) in a heat supply network can realize information conformity and information share roundly, which makes management of information improve to a new level in district heating. When fault of the heat supply network occurs, the traditional methods make fault reaction time long and the efficiency low, and enlarge the fault harm. The system of fault analysis in a heat supply network based on GIS mainly simulates and calculates according to various fault conditions. By selection of valve shut-off schemes in fault conditions and simulation of various fault conditions, the fault treatment scheme can be optimized. The results of simulation can be shown in the GIS graphics with the aid of advanced image display function of GIS. The application of this system brings great significance to heating system on the management enhancing, fault number-reducing, quick decision-making and influence area diminishing in case of fault.

NREL GIS Data: Hawaii High Resolution Concentrating Solar Power | OpenEI  

Open Energy Info (EERE)

Concentrating Solar Power Concentrating Solar Power Dataset Summary Description Abstract - Monthly and annual average solar resource potential for the state of Hawaii. Purpose - Provide information on the solar resource potential for the state of Hawaii. The insolation values represent the average solar energy available to a concentrating collector on a 2-axis tracker, such as a dish or a power tower. Supplemental Info - This data provides monthly average and annual average daily total solar resource averaged over surface cells of 0.1 degrees in both latitude and longitude, or about 10 km in size. This data was developed using the State University of New York/Albany satellite radiation model. This model was developed by Dr. Richard Perez and collaborators at the National Renewable Energy Laboratory and other universities for the U.S. Department of Energy. Specific information about this model can be found in Perez, et al. (2002). This model uses hourly radiance images from geostationary weather satellites, daily snow cover data, and monthly averages of atmospheric water vapor, trace gases, and the amount of aerosols in the atmosphere to calculate the hourly total insolation (sun and sky) falling on a horizontal surface. Atmospheric water vapor, trace gases, and aerosols are derived from a variety of sources. A modified Bird model is used to calculate clear sky direct normal (DNI). This is then adjusted as a function of the ratio of clear sky global horizontal (GHI) and the model predicted GHI. Where possible, existing ground measurement stations are used to validate the data. Nevertheless, there is uncertainty associated with the meterological input to the model, since some of the input parameters are not avalable at a 10km resolution. As a result, it is believed that the modeled values are accurate to approximately 15% of a true measured value within the grid cell. Due to terrain effects and other microclimate influences, the local cloud cover can vary significantly even within a single grid cell. Furthermore, the uncertainty of the modeled estimates increase with distance from reliable measurement sources and with the complexity of the terrain.

Open Energy Info (EERE)

Low Resolution Concentrating Solar Power Resource Low Resolution Concentrating Solar Power Resource Dataset Summary Description Abstract: Monthly and annual average solar resource potential for Hawaii. Purpose: Provide information on the solar resource potential for Hawaii. The insolation values represent the average solar energy available to a flat plate collector, such as a photovoltaic panel, oriented due south at an angle from horizontal equal to the latitude of the collector location. Supplemental_Information: This data provides monthly average and annual average daily total solar resource averaged over surface cells of approximately 40 km by 40 km in size. This data was developed from the Climatological Solar Radiation (CSR) Model. The CSR model was developed by the National Renewable Energy Laboratory for the U.S. Department of Energy. Specific information about this model can be found in Maxwell, George and Wilcox (1998) and George and Maxwell (1999). This model uses information on cloud cover, atmostpheric water vapor and trace gases, and the amount of aerosols in the atmosphere to calculate the monthly average daily total insolation (sun and sky) falling on a horizontal surface. The cloud cover data used as input to the CSR model are an 7-year histogram (1985-1991) of monthly average cloud fraction provided for grid cells of approximately 40km x 40km in size. Thus, the spatial resolution of the CSR model output is defined by this database. The data are obtained from the National Climatic Data Center in Ashville, North Carolina, and were developed from the U.S. Air Force Real Time Nephanalysis (RTNEPH) program. Atmospheric water vapor, trace gases, and aerosols are derived from a variety of sources. The procedures for converting the collector at latitude tilt are described in Marion and Wilcox (1994). Where possible, existing ground measurement stations are used to validate the data. Nevertheless, there is uncertainty associated with the meterological input to the model, since some of the input parameters are not avalible at a 40km resolution. As a result, it is believed that the modeled values are accurate to approximately 10% of a true measured value within the grid cell. Due to terrain effects and other micoclimate influences, the local cloud cover can vary significantly even within a single grid cell. Furthermore, the uncertainty of the modeled estimates increase with distance from reliable measurement sources and with the complexity of the terrain.

Constructing a GIS-based 3D urban model using LiDAR and aerial photographs  

E-Print Network (OSTI)

Due to the increasing availability of high-resolution remotely sensed imagery and detailed terrain surface elevation models, urban planners and municipal managers can now model and visualize the urban space in three dimensions. The traditional approach to the representation of urban space is 2D planimetric maps with building footprints, facilities and road networks. Recently, a number of methods have been developed to represent true 3D urban models. Those include panoramic imaging, Virtual Reality Modeling Language (VRML), and Computer-aided Design (CAD). These methods focus on aesthetic representation, but they do not have sufficient spatial query and analytical capabilities. This research evaluates the conventional approaches to 3D urban models, and identifies their advantages and limitations; GIS functionalities have been combined with 3D urban visualization techniques to develop a GIS-based urban modeling method; The algorithms and techniques have been explored to derive urban objects and their attributes from airborne LiDAR and high-resolution imagery for constructing and visualizing 3D urban models; and 3D urban models for the Texas A&M University (TAMU) campus and downtown Houston have been implemented using the algorithms and techniques developed in this research. By adding close-range camera images and highresolution aerial photographs as the texture of urban objects, effect of photorealism visualization has been achieved for walk-through and fly-through animations. The Texas A&M University campus model and the downtown Houston model have been implemented to offer proof-of-concept, namely, to demonstrate the advantages of the GIS-based approach. These two prototype applications show that the GIS-based 3D urban modeling method, by coupling ArcGIS and MultiGen-Paradigm Site Builder 3D software, can realize the desired functionalities in georeferencing, geographical measurements, spatial query, spatial analysis, and numerical modeling in 3D visual environment.

Evaluation of Horizontal Seismic Hazard of Shahrekord, Iran  

Science Conference Proceedings (OSTI)

This paper presents probabilistic horizontal seismic hazard assessment of Shahrekord, Iran. It displays the probabilistic estimate of Peak Ground Horizontal Acceleration (PGHA) for the return period of 75, 225, 475 and 2475 years. The output of the probabilistic seismic hazard analysis is based on peak ground acceleration (PGA), which is the most common criterion in designing of buildings. A catalogue of seismic events that includes both historical and instrumental events was developed and covers the period from 840 to 2007. The seismic sources that affect the hazard in Shahrekord were identified within the radius of 150 km and the recurrence relationships of these sources were generated. Finally four maps have been prepared to indicate the earthquake hazard of Shahrekord in the form of iso-acceleration contour lines for different hazard levels by using SEISRISK III software.

Horizontal Well Placement Optimization in Gas Reservoirs Using Genetic Algorithms  

E-Print Network (OSTI)

Horizontal well placement determination within a reservoir is a significant and difficult step in the reservoir development process. Determining the optimal well location is a complex problem involving many factors including geological considerations, reservoir and fluid properties, economic costs, lateral direction, and technical ability. The most thorough approach to this problem is that of an exhaustive search, in which a simulation is run for every conceivable well position in the reservoir. Although thorough and accurate, this approach is typically not used in real world applications due to the time constraints from the excessive number of simulations. This project suggests the use of a genetic algorithm applied to the horizontal well placement problem in a gas reservoir to reduce the required number of simulations. This research aims to first determine if well placement optimization is even necessary in a gas reservoir, and if so, to determine the benefit of optimization. Performance of the genetic algorithm was analyzed through five different case scenarios, one involving a vertical well and four involving horizontal wells. The genetic algorithm approach is used to evaluate the effect of well placement in heterogeneous and anisotropic reservoirs on reservoir recovery. The wells are constrained by surface gas rate and bottom-hole pressure for each case. This project's main new contribution is its application of using genetic algorithms to study the effect of well placement optimization in gas reservoirs. Two fundamental questions have been answered in this research. First, does well placement in a gas reservoir affect the reservoir performance? If so, what is an efficient method to find the optimal well location based on reservoir performance? The research provides evidence that well placement optimization is an important criterion during the reservoir development phase of a horizontal-well project in gas reservoirs, but it is less significant to vertical wells in a homogeneous reservoir. It is also shown that genetic algorithms are an extremely efficient and robust tool to find the optimal location.

Acid Placement in Acid Jetting Treatments in Long Horizontal Wells  

E-Print Network (OSTI)

In the Middle East, extended reach horizontal wells (on the order of 25,000 feet of horizontal displacement) are commonly acid stimulated by jetting acid out of drill pipe. The acid is jetted onto the face of the openhole wellbore as the drill pipe is withdrawn from the well. The jetting action helps to remove the drilling fluid filter cake and promote the acid to penetrate into the formation and form wormholes to stimulate the well. However, with very long sections of wellbore open to flow, the acid placement and subsequent wormhole distribution and penetration depths are uncertain. This study has modeled the acid jetting process using a comprehensive model of acid placement and wormhole propagation in a horizontal well. It is presumed that the acid jetting tool removes the drilling mud filter cake, so that no filter cake exists between the end of the drill pipe and the toe of the well. Correspondingly, the model also assumes that there is an intact, low-permeability filter cake on the borehole wall between the end of the drill pipe and the heel of the well. The drill pipe is modeled as being withdrawn from the well during the acid jetting treatment, as is done in practice. The acidizing simulator predicts the distribution of acid and the depths of wormholes formed as functions of time and position during the acid jetting treatment. The model shows that the acid jetting process as typically applied in these wells preferentially stimulates the toe region of the horizontal well. Comparisons of the simulation predictions with published data for acid jetting treatments in such wells showed good general agreement. Based on the simulation study, this study presents recommendations for improved acid jetting treatment procedures to improve the distribution of acid injected into the formation.

Modeling performance of horizontal, undulating, and multilateral wells  

E-Print Network (OSTI)

Horizontal, undulating, and multilateral wells are relatively new alternatives in field development because they can increase the productivity per well and reduce the cost of field development. Because the feasibility of these wells may not be valid in some reservoirs, well performance should be verified before making decisions. Undulation is usually associated to horizontal wells with some degrees. Existing inflow performance models do not account for the undulation of the well, which can cause significant error and economic loss. Moreover, some of the inflow models ignore pressure drop along the lateral, which is definitely not true in high production and long lateral wells. The inflow performance models of horizontal, undulating, and multilateral wells are developed in this study. The models can be divided into two main categories: the closed form model and the line source model. The closed form model applies for relatively low vertical permeability formations for the single-phase system and twophase system. The model is flexible and easy to apply with reasonable accuracy. The line source model does not have any restrictions with permeability. The model applies for single-phase system. The model is very accurate and easy to use. Both models can be applied to various well trajectories with realizable accuracy. As a result of this study, the well performance of unconventional well trajectories can be predicted and optimized.

Optimization of fractured well performance of horizontal gas wells  

E-Print Network (OSTI)

In low-permeability gas reservoirs, horizontal wells have been used to increase the reservoir contact area, and hydraulic fracturing has been further extending the contact between wellbores and reservoirs. This thesis presents an approach to evaluate horizontal well performance for fractured or unfractured gas wells and a sensitivity study of gas well performance in a low permeability formation. A newly developed Distributed Volumetric Sources (DVS) method was used to calculate dimensionless productivity index for a defined source in a box-shaped domain. The unique features of the DVS method are that it can be applied to transient flow and pseudo-steady state flow with a smooth transition between the boundary conditions. In this study, I conducted well performance studies by applying the DVS method to typical tight sandstone gas wells in the US basins. The objective is to determine the best practice to produce horizontal gas wells. For fractured wells, well performance of a single fracture and multiple fractures are compared, and the effect of the number of fractures on productivity of the well is presented based on the well productivity. The results from this study show that every basin has a unique ideal set of fracture number and fracture length. Permeability plays an important role on dictating the location and the dimension of the fractures. This study indicated that in order to achieve optimum production, the lower the permeability of the formation, the higher the number of fractures.

Horizontal natural gas storage caverns and methods for producing same  

DOE Patents (OSTI)

The invention provides caverns and methods for producing caverns in bedded salt deposits for the storage of materials that are not solvents for salt. The contemplated salt deposits are of the bedded, non-domed variety, more particularly salt found in layered formations that are sufficiently thick to enable the production of commercially usefully sized caverns completely encompassed by walls of salt of the formation. In a preferred method, a first bore hole is drilled into the salt formation and a cavity for receiving insolubles is leached from the salt formation. Thereafter, at a predetermined distance away from the first bore hole, a second bore hole is drilled towards the salt formation. As this drill approaches the salt, the drill assumes a slant approach and enters the salt and drills through it in a horizontal direction until it intersects the cavity for receiving insolubles. This produces a substantially horizontal conduit from which solvent is controlledly supplied to the surrounding salt formation, leaching the salt and producing a concentrated brine which is removed through the first bore hole. Insolubles are collected in the cavity for receiving insolubles. By controlledly supplying solvent, a horizontal cavern is produced with two bore holes extending therefrom.

Horizontal well improves oil recovery from polymer flood--  

Science Conference Proceedings (OSTI)

Horizontal drilling associated with an injection scheme appears to be highly promising for obtaining additional oil recovery. Horizontal well CR 163H, in the Chateaurenard field is discussed. It demonstrated that a thin unconsolidated sand can be successfully drilled and cased. The productivity index (PI) of the well was much greater than vertical wells, and an unproduced oil bank was successfully intersected. On the negative side, it was necessary to pump low in a very deviated part of the well, and the drilling cost was high compared to an onshore vertical well. CR 163H was the fifth and probably most difficult horizontal well drilled by Elf Aquitaine. Located within a polymer-flood project, the target was a 7-m thick sand reservoir at a vertical depth of 590:0080 m. In this inverted seven-spot configuration with one injector in the center and six producers at a distance of 400 m, a polymer solution was injected from 1977 to 1983, followed by water injection.

Due to terrain effects and other micoclimate influences, the local cloud cover can vary significantly even within a single grid cell. Furthermore, the uncertainty of the modeled estimates increase with distance from reliable measurement sources and with the complexity of the terrain.

Effects of a GIS Course on Three Components of Spatial Literacy  

E-Print Network (OSTI)

This research investigated whether completing an introductory GIS course affects college students' spatial literacy as defined by spatial habits of mind, spatial concepts and thinking skills, and critical spatial thinking. This study employed three tests (spatial habits of mind inventory, spatial concepts and skills test, critical spatial thinking oral test) to measure students' performance on these three elements. Furthermore, this research investigated the relationship among the components. Pre- and post-tests were conducted at the beginning and the end of the 2010 fall semester, and Texas A&M undergraduate students participated in the research. The following four research questions were examined. The first research question investigated whether GIS learning improves spatial habits of mind (n = 168). Five sub-dimensions of spatial habits of mind (pattern recognition, spatial description, visualization, spatial concept use, and spatial tool use) were identified. Overall, GIS students' spatial habits of mind were enhanced. However, variations existed when considering students' performance by dimension. The second research question explored whether GIS learning affects students' understanding and use of spatial concepts and thinking skills (n = 171). This research found that the GIS course was beneficial in improving students' spatial cognition. Students increased their understanding of key spatial concepts and applied conceptual understanding into wider contexts with advanced spatial thinking skills. The third research question examined the effects of a GIS course through interviews on the three sub-dimensions of critical spatial thinking: data reliability, spatial reasoning, and problem-solving validity (n = 32). The quantitative analyses indicated that participants developed their ability regarding these three sub-dimensions of critical spatial thinking. In particular, their ability to assess data reliability and problem-solving validity improved, an effect not likely to be enhanced by other coursework. Findings from qualitative thematic analysis confirmed these quantitative outcomes. The final research question probed the relationships among the three components of spatial literacy. Pearson?s correlation coefficient, a 3D space (termed "score space" in this study), a test for independence, and an exploratory factor analysis suggested that the three components are positively correlated. However, more research is necessary to confirm the results reported in this study.

Studies on bottomland hardwood forest restoration and teaching with geographic information systems (GIS) in ecology labs  

E-Print Network (OSTI)

The development of graduate students in the sciences preparing for careers in academia has long included elements to advance students as science researchers, but recent emphasis is being placed on developing students as instructors and education researchers as well. As such, objectives of this study included assessments of seedling responses to hydrology typical of floods in urban settings, the role of created microtopography in community development of a bottomland hardwood forest, and the influence of geographic information systems (GIS) on student motivation and conceptual knowledge. Substantial losses of bottomlands in Texas necessitate restoration to regain the ecosystem services that they provide. Restoration of proper hydrology is the most important aspect of wetland restoration, but this can prove difficult in urbanizing environments where hydrology has been irreversibly altered. Microtopography has been shown to be an important component of bottomland hardwood forests, and its restoration may aid in hydrologic restoration as gradients are created that support a diverse community. Tree seedlings were subjected to experimental flooding regimes typical of floodplain forests in rural and urban settings. Growth rates of seedlings varied over time and differed depending on species and treatment. Created microtopography resulted in a spatially heterogeneous system similar to that of natural bottomlands and strongly influenced hydrology, soil properties, survival of planted seedlings, and abundance and distribution of colonizing species. Proper bottomland restoration in urbanizing environments should include species selection based on current and potential future hydrologic conditions. In addition, restoring microtopography may improve survival of a variety of species introduced during restoration, as well as enhance colonization of a diverse plant community under changing hydrologic regimes. Trends indicated a slight improvement in attitude and performance for students that used GIS. More important, the authenticity of the experience appeared to affect student attitude. The effective use of GIS in teaching may be scale-dependent. Smallscale phenomena may be assessed as easily in a field exercise as with GIS. Using GIS to assess large-scale, complex patterns may have a substantial impact on student understanding. Further studies are needed to determine direct benefits of teaching with GIS in undergraduate ecology classrooms.

Integration of Predicted Atmospheric Contaminant Plumes into ArcView GIS  

Science Conference Proceedings (OSTI)

The Savannah River National Laboratory (SRNL) plays a key role in emergency response scenarios in which there may be a release of atmospheric chemical or radiological contamination at the DOE's Savannah River Site (SRS). Meteorologists at SRNL use a variety of tools to predict the path of the plume and levels of contamination along the path. These predictions are used to guide field teams that take sample measurements for verification. Integration of these predicted plumes as well as field measurements into existing Geographic Information System (GIS) interactive maps provides key additional information for decision makers during an emergency. In addition, having this information in GIS format facilitates sharing the information with other agencies that use GIS. In order to be useful during an emergency, an application for converting predictions or measurements into GIS format must be automated and simple to use. Thus, a key design goal in developing such applications is ease of use. Simple menu selections and intuitive forms with graphical user interfaces are used to accomplish this goal. Applications have been written to convert two different predictive code results into ArcView GIS. Meteorologists at SRNL use the Puff/Plume code, which is tied to real-time wind data, to predict the direction and spread of the atmospheric plume for early assessment. The calculated circular puffs are converted into an ArcView polygon shapefile with attributes for predicted time, dose, and radius of the puff. The meteorologists use the more sophisticated Lagrangian Particle Dispersion Model (LPDM) to predict particle dispersion and deposition. The calculational grid is brought into ArcView as a point shapefile and then interpolated to ARC GRID format using Spatial Analyst. This GRID can then be contoured into a line shapefile, which is easily shared with other agencies. The deposition grid is also automatically contoured for values that correspond to FDA Derived Intervention Levels for beef, produce, and dairy products. Decision makers at SRS routinely use these predicted plumes to direct field teams. In the case of a strong release, this information can be used to decide whether to evacuate a particular area. Having this information in GIS format may aid the decision maker because other infrastructure information can be overlaid with geographic reference.

Chemical wellbore plug for zone isolation in horizontal wells  

E-Print Network (OSTI)

A new technique for zone isolation in horizontal wells has been proposed. The new technique consists of three sequential stages: (i) setting a chemical wellbore plug in the horizontal section upstream of the zone to be isolated, (ii) spotting a gel just downstream of the wellbore plug and squeezing the gel into the zone to be isolated, and (iii) washing or drilling through excess gel and the wellbore plug to clean the borehole prior to production. The main objective of this research is to investigate the feasibility of setting a chemical wellbore plug in a horizontal wellbore. Two main problems associated with the wellbore plug were investigated: (a) method of placement of the plug so that slumping would not occur, and (b) selection and testing of chemicals that could be used to make wellbore plugs with sufficiently high holding pressures. Three chemicals, used in the oil industry for gas and/or water shut-off, were selected for the study. The commercial names of these chemicals were SEAL, PERMASEAL and TEXPLUG. Experimental apparatus were designed and constructed to study placement techniques and to measure the holding pressures of the wellbore plugs. The horizontal wellbore models consisted of PVC pipes internally lined with sand. The X-ray CT scanner was used to obtain cross-sectional images of the plug to help understand the shear mechanisms involved. The experimental results indicate that a plug could be placed in a horizontal wellbore with minimum slumping, if the plug is introduced into a viscous completion brine pill. For TEXPLUG, a suitable completion brine would contain 100,000 ppm NaCi and 4 lb/bbl CMC (carboxyl methyl cellulose). Further, results indicate that only TEXPLUG has a sufficiently high holding pressure (about 340 psi for 37 in. long, 1 in. I.D. plug) necessary for a wellbore plug. Based on experimental results, the proposed new isolation technique appears to be viable. However, further experimental studies are required, particularly to evaluate the effectiveness of the wellbore plug in conjunction with displacement of formation gels.

The Performance of Fractured Horizontal Well in Tight Gas Reservoir  

E-Print Network (OSTI)

Horizontal wells have been used to increase reservoir recovery, especially in unconventional reservoirs, and hydraulic fracturing has been applied to further extend the contact with the reservoir to increase the efficiency of development. In the past, many models, analytical or numerical, were developed to describe the flow behavior in horizontal wells with fractures. Source solution is one of the analytical/semi-analytical approaches. To solve fractured well problems, source methods were advanced from point sources to volumetric source, and pressure change inside fractures was considered in the volumetric source method. This study aims at developing a method that can predict horizontal well performance and the model can also be applied to horizontal wells with multiple fractures in complex natural fracture networks. The method solves the problem by superposing a series of slab sources under transient or pseudosteady-state flow conditions. The principle of the method comprises the calculation of semi-analytical response of a rectilinear reservoir with closed outer boundaries. A statistically assigned fracture network is used in the study to represent natural fractures based on the spacing between fractures and fracture geometry. The multiple dominating hydraulic fractures are then added to the natural fracture system to build the physical model of the problem. Each of the hydraulic fractures is connected to the horizontal wellbore, and the natural fractures are connected to the hydraulic fractures through the network description. Each fracture, natural or hydraulically induced, is treated as a series of slab sources. The analytical solution of superposed slab sources provides the base of the approach, and the overall flow from each fracture and the effect between the fractures are modeled by applying superposition principle to all of the fractures. It is assumed that hydraulic fractures are the main fractures that connect with the wellbore and the natural fractures are branching fractures which only connect with the main fractures. The fluid inside of the branch fractures flows into the main fractures, and the fluid of the main fracture from both the reservoir and the branch fractures flows to the wellbore. Predicting well performance in a complex fracture network system is extremely challenged. The statistical nature of natural fracture networks changes the flow characteristic from that of a single linear fracture. Simply using the single fracture model for individual fracture, and then adding the flow from each fracture for the network could introduce significant error. This study provides a semi-analytical approach to estimate well performance in a complex fracture network system.

NREL GIS Data: Continental United States High Resolution Concentrating  

Open Energy Info (EERE)

High Resolution Concentrating High Resolution Concentrating Solar Power Dataset Summary Description Abstract: Monthly and annual average solar resource potential for the lower 48 states of the United States of America. Purpose: Provide information on the solar resource potential for the for the lower 48 states of the United States of America. Supplemental_Information: This data provides monthly average and annual average daily total solar resource averaged over surface cells of approximatley 40 km by 40 km in size. This data was developed from the Climatological Solar Radiation (CSR) Model. The CSR model was developed by the National Renewable Energy Laboratory for the U.S. Department of Energy. Specific information about this model can be found in Maxwell, George and Wilcox (1998) and George and Maxwell (1999). This model uses information on cloud cover, atmostpheric water vapor and trace gases, and the amount of aerosols in the atmosphere to calculate the monthly average daily total insolation (sun and sky) falling on a horizontal surface. The cloud cover data used as input to the CSR model are an 7-year histogram (1985-1991) of monthly average cloud fraction provided for grid cells of approximately 40km x 40km in size. Thus, the spatial resolution of the CSR model output is defined by this database. The data are obtained from the National Climatic Data Center in Ashville, North Carolina, and were developed from the U.S. Air Force Real Time Nephanalysis (RTNEPH) program. Atmospheric water vapor, trace gases, and aerosols are derived from a variety of sources. The procedures for converting the collector at latitude tilt are described in Marion and Wilcox (1994). Where possible, existing ground measurement stations are used to validate the data. Nevertheless, there is uncertainty associated with the meterological input to the model, since some of the input parameters are not avalible at a 40km resolution. As a result, it is believed that the modeled values are accurate to approximately 10% of a true measured value within the grid cell. Due to terrain effects and other micoclimate influences, the local cloud cover can vary significantly even within a single grid cell. Furthermore, the uncertainty of the modeled estimates increase with distance from reliable measurement sources and with the complexity of the terrain.

Science Conference Proceedings (OSTI)

The Savannah River Site (SRS) is a 310-square-mile Department of Energy site located near Aiken, South Carolina. With a workforce of over 10,000 employees and subcontractors, SRS emergency personnel must be able to respond to an emergency event in a timely and effective manner, in order to ensure the safety and security of the Site. Geographic Information Systems (GIS) provides the technology needed to give managers and emergency personnel the information they need to make quick and effective decisions. In the event of a site evacuation, knowing the number of on-site personnel to evacuate from a given area is an essential piece of information for emergency staff. SRS has developed a GIS Dynamic Population Model Tool to quickly communicate real-time information that summarizes employee populations by facility area and building and then generates dynamic maps that illustrate output statistics.

A GIS-based Bayesian approach for analyzing spatial-temporal patterns of traffic crashes  

E-Print Network (OSTI)

This thesis develops a GIS-based Bayesian approach for area-wide traffic crash analysis. Five years of crash data from Houston, Texas, are analyzed using a geographic information system (GIS), and spatial-temporal patterns of relative crash risk are identified based on a hierarchical Bayesian approach. This Bayesian approach is used to filter the uncertainty in the data and identify and rank roadway segments with potentially high relative risks for crashes. The results provide a sound basis to take preventive actions to reduce the risks in these segments. To capture the real safety indications better, this thesis differentiates the risks in different directions of the roadways, disaggregates different road types, and utilizes GIS to analyze and visualize the spatial relative crash risks in 3-D views according to different temporal scales. Results demonstrate that the approach is effective in spatially smoothing the relative crash risks, eliminating the instability of estimates while maintaining real safety trends. The posterior risk maps show high-risk roadway segments in 3-D views, which is more reader friendly than the conventional 2-D views. The results are also useful for travelers to choose relatively safer routes.

An Alternate Career Choice for the Geography Major: Map, GIS, or Geographic Information Librarianship  

E-Print Network (OSTI)

The field of Map, GIS and Geographic Information Librarianship has expanded over the past decade. This expansion is due in part to the addition of GIS dataset collections in many university libraries, specialized government or corporate information agencies. Librarians holding a bachelors degree in geography, earth sciences or environmental sciences, are in high demand to fill positions as a Map, GIS or Geographic Information librarian. The standard requirement for these positions, beyond the bachelors degree, is a masters degree from an American Library Association accredited library/information science program. There are 57 ALA accredited library/information science programs in the US, four of which are located in the SWAAG region. Masters degree curriculum varies, but generally requires 36 hours or more, and some programs require a thesis or practicum. Undergraduates who are interested in a service profession and enjoy the research process, instruction and organization of information are good candidates for this career. A description of the traditional and evolving work duties, starting salaries, and how the geography degree supports this specialization will be included in the presentation.

Horizontal-axis clothes washer market poised for expansion  

SciTech Connect

The availability of energy- and water-efficient horizontal-axis washing machines in the North American market is growing, as US and European manufacturers position for an expected long-term market shift toward horizontal-axis (H-axis) technology. Four of the five major producers of washing machines in the US are developing or considering new H-axis models. New entrants, including US-based Staber Industries and several European manufacturers, are also expected to compete in this market. The intensified interest in H-axis technology is partly driven by speculation that new US energy efficiency standards, to be proposed in 1996 and implemented in 1999, will effectively mandate H-axis machines. H-axis washers typically use one-third to two-thirds less energy, water, and detergent than vertical-axis machines. Some models also reduce the energy needed to dry the laundry, since their higher spin speeds extract more water than is typical with vertical-axis designs. H-axis washing machines are the focus of two broadly-based efforts to support coordinated research and incentive programs by electric, gas, and water utilities: The High-Efficiency Laundry Metering/Marketing Analysis (THELMA), and the Consortium for Energy Efficiency (CEE) High-Efficiency Clothes Washer Initiative. These efforts may help to pave the way for new types of marketing partnerships among utilities and other parties that could help to speed adoption of H-axis washers.

E-Print Network (OSTI)

Context. Abundance anomalies have been observed in field sdB stars and in nearly all Horizontal Branch (HB) stars of globular clusters with Teff > 11 000K whatever be the cluster metallicity. Aims. The aim is to determine the abundance variations to be expected in sdB stars and in HB stars of metallicities Z \\geq 0.0001 and what observed abundances teach us about hydrodynamical processes competing with atomic diffusion. Methods. Complete stellar evolution models, including the effects of atomic diffusion and radiative acceleration, have been computed from the zero age main-sequence for metallicities of Z0 = 0.0001, 0.001, 0.004 and 0.02. On the HB the masses were selected to cover the Teff interval from 7000 to 37000K. Some 60 evolutionary HB models were calculated. The calculations of surface abundance anomalies during the horizontal branch depend on one parameter, the surface mixed mass. Results. For sdB stars with Teff 11 000K in all observed clusters, independent of metallicity, it was found that most ob...

Horizontal well success spurs more Devonian work in Michigan  

Science Conference Proceedings (OSTI)

The principal objective of this DOE-sponsored project was to drill a horizontal demonstration well in order to test the viability of using horizontal wells to recover bypassed oil from the Dundee reservoir in Crystal field. In addition, a modern log suite through the entire Dundee formation and a conventional core through the productive interval, the oil/water contact, and the upper part of the water leg were to be obtained. During the early years of Dundee development in central Michigan, it was common practice to drill only a short distance below the cap limestone into the top of the Dundee porosity zone before completing a well in order to prevent lost circulation and blowouts in vuggy and fractured dolomites and to avoid penetration of the oil/water contact and minimize water coning. As a result, the characteristics of the Dundee reservoir in central Michigan are poorly known and the decision to attempt an improved recovery program in Crystal field had to be based on field volumetrics, individual well productivities, and well development/abandonment histories. The new core and log data from the demonstration well will provide an important anchor point for regional Dundee reservoir characterization studies.

The effect of horizontal resolution on cloud radiative forcing in the ECMWF model. PCMDI report No. 22  

SciTech Connect

With expanding computer capability and capacity there has been considerable interest in increasing the resolution in GCMs. The primary driving force behind this are two fold: (1) increased resolution may reduce the systematic errors inherent in parameterization of sub-grid scale processes, and (2) higher resolution may improve confidence in regional scale studies of climatic features that are orographically influenced -- such as the effect of the Tibetan Plateau on the East Asian Monsoon. This study focuses on the effect of horizontal resolution on the spatial and temporal systematic errors of cloud radiative forcing and its components. In this paper, the top-of-the-atmosphere radiation fields are taken from a series of simulations using the European Centre for Medium Range Forecasts (ECMWF) general circulation model (cycle 33), run at four different horizontal resolutions. Section 2 discusses the concept of cloud radiative forcing and describes the simulations from the ECMWF model. The observed global field of cloud forcing from ERBE is presented in section 3 along with the model-produced fields of the net solar and longwave cloud forcing. The seasonal effect of forcing is described in section 4, and the results are summarized in section 5.

Sand control in horizontal wells in heavy-oil reservoirs  

SciTech Connect

Recent advances in horizontal-well technology has greatly improved the potential for heavy oil recovery. Such recovery may be hampered, however, by sanding problems associated with most heavy-oil reservoirs. These reservoir sands are mostly unconsolidated and may lead to severe productivity-loss problems if produced freely. This paper offers recommendations for sand control in three Canadian heavy-oil reservoirs. Experimental evidence has shown that minimizing the annular space between the casing and the open hole is important, especially in the case of smaller wire space, lower oil viscosity, and thinner pay zone. Several types of wire-wrapped screens and flexible liners were tested for sand control. Only flexible liners reduced sand production to a negligible amount.

IDENTIFYING BLUE HORIZONTAL BRANCH STARS USING THE z FILTER  

SciTech Connect

In this paper we present a new method for selecting blue horizontal branch (BHB) candidates based on color-color photometry. We make use of the Sloan Digital Sky Survey z band as a surface gravity indicator and show its value for selecting BHB stars from quasars, white dwarfs, and main-sequence A-type stars. Using the g, r, i, and z bands, we demonstrate that extraction accuracies on a par with more traditional u, g, and r photometric selection methods may be achieved. We also show that the completeness necessary to probe major Galactic structure may be maintained. Our new method allows us to efficiently select BHB stars from photometric sky surveys that do not include a u-band filter such as the Panoramic Survey Telescope and Rapid Response System.

Horizontal Visibility graphs generated by type-II intermittency  

E-Print Network (OSTI)

In this contribution we study the onset of chaos via type-II intermittency within the framework of Horizontal Visibility graph theory. We construct graphs associated to time series generated by an iterated map close to a Neimark-Sacker bifurcation and study, both numerically and analytically, their main topological properties. We find well defined equivalences between the main statistical properties of intermittent series (scaling of laminar trends and Lyapunov exponent) and those of the resulting graphs, and accordingly construct a graph theoretical description of type-II intermittency. We finally recast this theory into a graph-theoretical renormalization group framework, and show that the fixed point structure of RG flow diagram separates regular, critical and chaotic dynamics.

Furnace characterization for horizontal shipping container thermal testing  

SciTech Connect

In order to perform regulatory thermal tests required by 10 CFR 71.73(c)(3) on the newly designed Horizontal Shipping Container (HSC), it was necessary to find a company involved in the business of heat treating who was willing to allow their furnace to be used for these tests. Of the companies responding to a request for interest, Lindberg Heat Treating Company`s Solon, Ohio, facility was found to be the best available vendor for this activity. Their furnace was instrumented and characterized such that these tests could be performed in a manner that would conform to the specifications contained in 10 CFR 71. It was found that Lindberg`s furnace was usable for this task, and recommendations concerning the use of this furnace for the above stated purpose are made herein.

Geothermal heat cycle research: Supercritical cycle with horizontal counterflow condenser  

DOE Green Energy (OSTI)

The Heat Cycle Research Program, which is being conducted for the Department of Energy, has as its objective the development of the technology for effecting the improved utilization of moderate temperature geothermal resources. To meet this objective, the program has as one of its goals to improve the performance of geothermal binary cycles to levels approaching the practicable thermodynamic maximum. In pursuit of this goal, tests are being conducted at the Heat Cycle Research Facility located at the DOE Geothermal Test Facility, East Mesa, California. The current testing involves the investigation of binary power cycle performance utilizing mixtures of non-adjacent hydrocarbons as the working fluids, with supercritical vaporization and in-tube condensation of the working fluid. In addition to the present test program, preparations are being made to investigate the binary cycle performance improvements which can be achieved by allowing supersaturated vapor expansions in the turbine. These efforts are anticipated to verify that through the utilization of these advanced power cycle concepts and allowing the supersaturated turbine expansions, improvements of up to 28% in the net geofluid effectiveness (net watt hours plant output per pound of geofluid) over conventional binary power plants can be achieved. Results are presented for the recent testing including those tests examining the performance of the countercurrent condenser at different tube inclinations. Performance of the heaters and the condenser in a vertical orientation can be predicted well with existing methods and data. The condenser in its near horizontal orientation performs slightly worse than in its vertical orientation. Some problems have been encountered in predicting the performance in the horizontal orientation. There is no evidence of departure from integral condensation in either orientation.

AGS tune jump system to cross horizontal depolarization resonances overview  

SciTech Connect

Two partial snakes overcome the vertical depolarizing resonances in the AGS. But a new type of depolarizing intrinsic resonance from horizontal motion appeared. We reduce these using horizontal tune jumps timed to these resonances. We gain a factor of six in crossing rate with a tune jump of 0.05 in 100 {micro}s. Two quadrapoles, we described in 2009, pulse 42 times, the current matching beam energy. The power supplies for these quads are described in detail elsewhere in this conference. The controls for the Jump Quad system is based on a BNL designed Quad Function Generator. Two modules are used; one for timing, and one to supply reference voltages. Synchronization is provided by a proprietary serial bus, the Event Link. The AgsTuneJump application predicts the times of the resonances during the AGS cycle and calculates the power supply trigger times from externally collected tune and energy versus time data and the Low and High PS voltage functions from a voltage to current model of the power supply. The system was commissioned during runs 09 & 10 and is operational. Many beam effects are described elsewhere. The TuneJump system has worked well and has caused little trouble save for the perturbations in the lattice having such a large effect due to our need to run with the vertical tune within a few thousandths of the integer tune. As these problems were mostly sorted out by correcting the 6th harmonic orbit distortions which caused a large 18 theta beta wave. Also running with minimal chromaticity reduces emittance growth. There are still small beta waves which are being addressed. The timing of the pulses is still being investigated, but as each crossing causes minimal polarization loss, this is a lengthy process.

Horizontal oil well applications and oil recovery assessment. Technical progress report, April--June 1994  

SciTech Connect

Thousands of horizontal wells are being drilled each year in the U.S.A. and around the world. Horizontal wells have increased oil and gas production rates 3 to 8 times those of vertical wells in many areas and have converted non-economic oil reserves to economic reserves. However, the use of horizontal technology in various formation types and applications has not always yielded anticipated success. The primary objective of this project is to examine factors affecting technical and economic success of horizontal well applications. The project`s goals will be accomplished through six tasks designed to evaluate the technical and economic success of horizontal drilling, highlight current limitations, and outline technical needs to overcome these limitations. Data describing operators` experiences throughout the domestic oil and gas industry will be gathered and organized. Canadian horizontal technology will also be documented with an emphasis on lessons the US industry can learn from Canada`s experience. MEI databases containing detailed horizontal case histories will also be used. All these data will be categorized and analyzed to assess the status of horizontal well technology and estimate the impact of horizontal wells on present and future domestic oil recovery and reserves.

Fuzzy GIS-based multi-criteria evaluation for U.S. Agave production as a Fuzzy GIS-based multi-criteria evaluation for U.S. Agave production as a bioenergy feedstock Title Fuzzy GIS-based multi-criteria evaluation for U.S. Agave production as a bioenergy feedstock Publication Type Report Refereed Designation Unknown Year of Publication 2013 Authors Lewis, Sarah M., Sthephen Gross, Axel Visel, Maggi Kelly, and William R. Morrow Keywords Agave, bioenergy, biofuel, fuzzy logic, geographic information systems, suitability mapping Abstract In the United States, renewable energy mandates calling for increased production of cellulosic biofuels will require a diversity of bioenergy feedstocks to meet growing demands. Within the suite of potential energy crops, plants within the genus Agave promise to be a productive feedstock in hot and arid regions. The potential distri- butions of Agave tequilana and Agave deserti in the United States were evaluated based on plant growth parameters identified in an extensive literature review. A geospatial suitability model rooted in fuzzy logic was developed that utilized a suite of biophysical criteria to optimize ideal geographic locations for this new crop, and several suitability scenarios were tested for each species. The results of this spatially explicit suitability model suggest that there is potential for Agave to be grown as an energy feedstock in the southwestern region of the United States - particularly in Arizona, California, and Texas - and a significant portion of these areas are proximate to existing transportation infrastructure. Both Agave species showed the highest state-level renewable energy benefit in Arizona, where agave plants have the potential to contribute 4.8-9.6% of the states' ethanol consumption, and 2.5-4.9% of its electricity consumption, for A. deserti and A. tequilana, respectively. This analysis supports the feasibility of Agave as a complementary bioenergy feedstock that can be grown in areas too harsh for conventional energy feedstocks.

Emerging Technologies in the Built Environment: Geographic Information Science (GIS), 3D Printing, and Additive Manufacturing  

SciTech Connect

Abstract 1: Geographic information systems emerged as a computer application in the late 1960s, led in part by projects at ORNL. The concept of a GIS has shifted through time in response to new applications and new technologies, and is now part of a much larger world of geospatial technology. This presentation discusses the relationship of GIS and estimating hourly and seasonal energy consumption profiles in the building sector at spatial scales down to the individual parcel. The method combines annual building energy simulations for city-specific prototypical buildings and commonly available geospatial data in a GIS framework. Abstract 2: This presentation focuses on 3D printing technologies and how they have rapidly evolved over the past couple of years. At a basic level, 3D printing produces physical models quickly and easily from 3D CAD, BIM (Building Information Models), and other digital data. Many AEC firms have adopted 3D printing as part of commercial building design development and project delivery. This presentation includes an overview of 3D printing, discusses its current use in building design, and talks about its future in relation to the HVAC industry. Abstract 3: This presentation discusses additive manufacturing and how it is revolutionizing the design of commercial and residential facilities. Additive manufacturing utilizes a broad range of direct manufacturing technologies, including electron beam melting, ultrasonic, extrusion, and laser metal deposition for rapid prototyping. While there is some overlap with the 3D printing talk, this presentation focuses on the materials aspect of additive manufacturing and also some of the more advanced technologies involved with rapid prototyping. These technologies include design of carbon fiber composites, lightweight metals processing, transient field processing, and more.

Spatial process and data models : toward integration of agent-based models and GIS.  

Science Conference Proceedings (OSTI)

The use of object-orientation for both spatial data and spatial process models facilitates their integration, which can allow exploration and explanation of spatial-temporal phenomena. In order to better understand how tight coupling might proceed and to evaluate the possible functional and efficiency gains from such a tight coupling, we identify four key relationships affecting how geographic data (fields and objects) and agent-based process models can interact: identity, causal, temporal and topological. We discuss approaches to implementing tight integration, focusing on a middleware approach that links existing GIS and ABM development platforms, and illustrate the need and approaches with example agent-based models.

The Global Grid  

E-Print Network (OSTI)

This paper puts forward the vision that a natural future stage of the electricity network could be a grid spanning the whole planet and connecting most of the large power plants in the world: this is the "Global Grid". The main driving force behind the Global Grid will be the harvesting of remote renewable sources, and its key infrastructure element will be the high capacity long transmission lines. Wind farms and solar power plants will supply load centers with green power over long distances. This paper focusses on the introduction of the concept, showing that a globally interconnected network can be technologically feasible and economically competitive. We further highlight the multiple opportunities emerging from a global electricity network such as smoothing the renewable energy supply and electricity demand, reducing the need for bulk storage, and reducing the volatility of the energy prices. We also discuss possible investment mechanisms and operating schemes. Among others, we envision in such a system...

Zero Discharge Water Management for Horizontal Shale Gas Well Development  

SciTech Connect

Hydraulic fracturing technology (fracking), coupled with horizontal drilling, has facilitated exploitation of huge natural gas (gas) reserves in the Devonian-age Marcellus Shale Formation (Marcellus) of the Appalachian Basin. The most-efficient technique for stimulating Marcellus gas production involves hydraulic fracturing (injection of a water-based fluid and sand mixture) along a horizontal well bore to create a series of hydraulic fractures in the Marcellus. The hydraulic fractures free the shale-trapped gas, allowing it to flow to the well bore where it is conveyed to pipelines for transport and distribution. The hydraulic fracturing process has two significant effects on the local environment. First, water withdrawals from local sources compete with the water requirements of ecosystems, domestic and recreational users, and/or agricultural and industrial uses. Second, when the injection phase is over, 10 to 30% of the injected water returns to the surface. This water consists of flowback, which occurs between the completion of fracturing and gas production, and produced water, which occurs during gas production. Collectively referred to as returned frac water (RFW), it is highly saline with varying amounts of organic contamination. It can be disposed of, either by injection into an approved underground injection well, or treated to remove contaminants so that the water meets the requirements of either surface release or recycle use. Depending on the characteristics of the RFW and the availability of satisfactory disposal alternatives, disposal can impose serious costs to the operator. In any case, large quantities of water must be transported to and from well locations, contributing to wear and tear on local roadways that were not designed to handle the heavy loads and increased traffic. The search for a way to mitigate the situation and improve the overall efficiency of shale gas production suggested a treatment method that would allow RFW to be used as make-up water for successive fracs. RFW, however, contains dissolved salts, suspended sediment and oils that may interfere with fracking fluids and/or clog fractures. This would lead to impaired well productivity. The major technical constraints to recycling RFW involves: identification of its composition, determination of industry standards for make-up water, and development of techniques to treat RFW to acceptable levels. If large scale RFW recycling becomes feasible, the industry will realize lower transportation and disposal costs, environmental conflicts, and risks of interruption in well development schedules.

Flow of fracturing foams in vertical, horizontal and inclined pipes  

E-Print Network (OSTI)

Foams are complex mixtures of a gas and a liquid, with the latter being the continuous phase. The rheological properties of foams are strongly influenced by parameters like temperature, absolute pressure, foam quality, texture, foam-channel wall effects, liquid phase properties, and type and concentration of surfactant. The high solids carrying capacity, the minimum amount of fluid placed in the formation, and the excellent fluid recovery after treatment are some of the advantages that foam fluids present when used during fracturing operations. This thesis is a study of foam flow in pipes, the pressure calculations, the study of rheological properties and their evaluation. The objectives of this research are to: 1. Compare various rheological models representing foams. 2. Develop an algorithm that finds the rheological parameters for the different models at different pressures in the pipe. 3. Provide an engineer with a method that predicts pressure at one end, if pressure at the other end is known, given the rheological parameters of the fluid, the diameter of the pipe and the inlet stream properties. 4. Provide a spreadsheet program for different fluid models that calculates pressures in an inclined, vertical or horizontal pipe. 5. Validate the programs. General curve fitting techniques are used to fit different models: namely, power law, Bingham plastic and Herschel Bulkley models to shear stress vs. shear rate data. The trend of the power law and Bingham plastic rheological parameters with respect to quality is observed. A method to estimate the rheological parameters at different pressures along the pipe using regression methods is developed. Spreadsheet programs for power law Bingham plastic and volume equalized power law model have been developed, which calculate pressures in inclined, horizontal and vertical pipes. The methods for the power law and Bingham plastic fluids are iterative methods. The volume equalized power law program adopts the volume equalized principle, which uses mechanical energy balance with frictional losses calculated from a rheological model. The mechanical energy balance is integrated to obtain a non-linear equation containing the unknown pressure.
