ADVANCED TECHNOLOGIES FOR STRIPPER GAS WELL ENHANCEMENT (open access)

ADVANCED TECHNOLOGIES FOR STRIPPER GAS WELL ENHANCEMENT

As part of Task 1 in Advanced Technologies for Stripper Gas Well Enhancement, Schlumberger Data & Consulting Services (DCS) joined with two Appalachian Basin producers, Great Lakes Energy Partners, LLC, and Belden & Blake Corporation to develop methodologies for identification and enhancement of stripper wells with economic upside potential. These industry partners previously provided us with data for more than 700 wells in northwestern Pennsylvania. Phase 1 goals of this project are to develop and validate methodologies that can quickly and cost-effectively identify underperforming wells with remediation potential. We have enhanced and streamlined our software and are using it with the latest versions of Microsoft's{trademark} Access and Excel programs. During the last quarter of 2002, Great Lakes provided us with additional data for approximately 2,200 wells located in their Cooperstown field situated in northwestern Pennsylvania. We identified approximately 130 potential remediation candidates, and Great Lakes personnel are currently reviewing this list for viable remediation. Within the last few weeks, a list of five candidates have been chosen for refract, in addition to two alternate wells. This field has provided a rigorous test of our software and analytical methods. We have processed all the information provided to us including the Cooperstown …

Agricultural and Environmental Input Parameters for the Biosphere Model (open access)

Agricultural and Environmental Input Parameters for the Biosphere Model

This analysis is one of 10 technical reports that support the Environmental Radiation Model for Yucca Mountain Nevada (ERMYN) (i.e., the biosphere model). It documents development of agricultural and environmental input parameters for the biosphere model, and supports the use of the model to develop biosphere dose conversion factors (BDCFs). The biosphere model is one of a series of process models supporting the total system performance assessment (TSPA) for the repository at Yucca Mountain. The ERMYN provides the TSPA with the capability to perform dose assessments. A graphical representation of the documentation hierarchy for the ERMYN is presented in Figure 1-1. This figure shows the interrelationships between the major activities and their products (the analysis and model reports) that were planned in ''Technical Work Plan for Biosphere Modeling and Expert Support'' (BSC 2004 [DIRS 169573]). The ''Biosphere Model Report'' (BSC 2004 [DIRS 169460]) describes the ERMYN and its input parameters.

Annual Report for LDRD-04-FS-019 The Innermost Inner Core: Fact or Artifact? (open access)

Annual Report for LDRD-04-FS-019 The Innermost Inner Core: Fact or Artifact?

There is considerable debate in the Earth sciences over the composition, thermal history, and dynamics of Earth's inner core. The details of structural models are based on precious few seismological observations of PKP travel times, due to the uneven distribution of large earthquakes and recording stations around the globe. Using state-of-the-art signal-processing techniques to measure and compile a unique set of global travel time data of surface-reflected seismic waves that propagate through the center of Earth (PKPPKP waves), we propose to investigate the existence of the innermost inner core. We will carry out a systematic investigation to determine the configuration of inner core anisotropy, which is currently biased by a limited spatial sampling of the inner core by PKP waves. We expect to collect data set of waveforms and identify PKPPKP energy arrivals on existing seismological records in a systematic form. We expect to demonstrate whether or not the existence of the innermost inner core can be supported by seismological data and to provide major constraints on the amount of inner core anisotropy. This is a topic of very high interest in the earth science community and the results would be of great importance not only to seismologists but to …

Assessing Terrorist Motivations for Attacking Critical "Chemical" Infrastructure (open access)

Assessing Terrorist Motivations for Attacking Critical "Chemical" Infrastructure

Certain types of infrastructure--critical infrastructure (CI)--play vital roles in underpinning our economy, security, and way of life. One particular type of CI--that relating to chemicals--constitutes both an important element of our nation's infrastructure and a particularly attractive set of potential targets. This is primarily because of the large quantities of toxic industrial chemicals (TICs) it employs in various operations and because of the essential economic functions it serves. This study attempts to minimize some of the ambiguities that presently impede chemical infrastructure threat assessments by providing new insight into the key motivational factors that affect terrorist organizations propensity to attack chemical facilities. Prepared as a companion piece to the Center for Nonproliferation Studies August 2004 study--''Assessing Terrorist Motivations for Attacking Critical Infrastructure''--it investigates three overarching research questions: (1) why do terrorists choose to attack chemical-related infrastructure over other targets; (2) what specific factors influence their target selection decisions concerning chemical facilities; and (3) which, if any, types of groups are most inclined to attack chemical infrastructure targets? The study involved a multi-pronged research design, which made use of four discrete investigative techniques to answer the above questions as comprehensively as possible. These include: (1) a review of terrorism and threat …

Automatic Enrollment in Section 401(k) Plans

This report discusses enrollment practices for 401k retirement plans. Historically, most employers that have sponsored retirement savings plans under §401(k) of the Internal Revenue Code (IRC) have required employees to decide whether to enroll in the plan. The Internal Revenue Service (IRS) has issued rulings to inform employers that current law allows them to enroll employees automatically, provided that the employee is notified in advance and is permitted to leave the plan.

Can fuzzy logic bring complex problems into focus? Modeling imprecise factors in environmental policy (open access)

Can fuzzy logic bring complex problems into focus? Modeling imprecise factors in environmental policy

In modeling complex environmental problems, we often fail to make precise statements about inputs and outcome. In this case the fuzzy logic method native to the human mind provides a useful way to get at these problems. Fuzzy logic represents a significant change in both the approach to and outcome of environmental evaluations. Risk assessment is currently based on the implicit premise that probability theory provides the necessary and sufficient tools for dealing with uncertainty and variability. The key advantage of fuzzy methods is the way they reflect the human mind in its remarkable ability to store and process information which is consistently imprecise, uncertain, and resistant to classification. Our case study illustrates the ability of fuzzy logic to integrate statistical measurements with imprecise health goals. But we submit that fuzzy logic and probability theory are complementary and not competitive. In the world of soft computing, fuzzy logic has been widely used and has often been the ''smart'' behind smart machines. But it will require more effort and case studies to establish its niche in risk assessment or other types of impact assessment. Although we often hear complaints about ''bright lines,'' could we adapt to a system that relaxes these …

Characterization of U(VI) Sorption-Desorption Processes and Model Upscaling (open access)

Characterization of U(VI) Sorption-Desorption Processes and Model Upscaling

The objectives of the overall collaborative EMSP effort (with which this project is associated) are to characterize sorption and desorption processes of U(VI) on pristine and contaminated Hanford sediments over a range of sediment facies and materials properties and to relate such characterization both to fundamental molecular-scale understanding and fieldscale models of geochemistry and mass transfer. The research is intended to provide new insights on the mechanisms of U(VI) retardation at Hanford, and to allow the development of approaches by which laboratory-developed geochemical models can be upscaled for defensible field-scale predictions of uranium transport in the environment.

Characterize Framework for Igneous Activity at Yucca Mountain, Nevada (open access)

Characterize Framework for Igneous Activity at Yucca Mountain, Nevada

The purpose of this scientific analysis report is threefold: (1) Present a conceptual framework of igneous activity in the Yucca Mountain region (YMR) consistent with the volcanic and tectonic history of this region and the assessment of this history by experts who participated in the probabilistic volcanic hazard analysis (PVHA) (CRWMS M&O 1996 [DIRS 100116]). Conceptual models presented in the PVHA are summarized and applied in areas in which new information has been presented. Alternative conceptual models are discussed, as well as their impact on probability models. The relationship between volcanic source zones defined in the PVHA and structural features of the YMR are described based on discussions in the PVHA and studies presented since the PVHA. (2) Present revised probability calculations based on PVHA outputs for a repository footprint proposed in 2003 (BSC 2003 [DIRS 162289]), rather than the footprint used at the time of the PVHA. This analysis report also calculates the probability of an eruptive center(s) forming within the repository footprint using information developed in the PVHA. Probability distributions are presented for the length and orientation of volcanic dikes located within the repository footprint and for the number of eruptive centers (conditional on a dike intersecting the …

Chemical and Biological Defense: DOD Needs to Continue to Collect and Provide Information on Tests and on Potentially Exposed Personnel (open access)

Chemical and Biological Defense: DOD Needs to Continue to Collect and Provide Information on Tests and on Potentially Exposed Personnel

A letter report issued by the General Accounting Office with an abstract that begins "In the 1962-74 time period, the Department of Defense (DOD) conducted a classified chemical and biological warfare test program--Project 112--that might have exposed service members and civilian personnel to chemical or biological agents. In 2000 the Department of Veterans Affairs (VA) began obtaining information from DOD about the program. Concerned that veterans and others might have health problems from exposure during Project 112 and similar DOD tests, Congress required DOD in the 2003 Defense Authorization Act to identify Project 112 tests and personnel potentially expose--service members and the number of civilian personnel--and other chemical and biological tests that might have exposed service members. GAO was required by the act and subsequent guidance from the congressional requesters to evaluate (1) DOD's process to identify the Project 112 tests and the service members and the number of civilian personnel potentially exposed, (2) DOD's progress in identifying similar tests outside Project 112, and (3) VA's progress in notifying DOD identified veterans."

Child Support Enforcement: New Reforms and Potential Issues (open access)

Child Support Enforcement: New Reforms and Potential Issues

P.L. 104-193 (the 1996 welfare reform law) made major changes to the Child Support Enforcement (CSE) program. Some of the changes include requiring states to increase the percentage of fathers identified, establishing an integrated, automated network linking all states to information about the location and assets of parents, and requiring states to implement more enforcement techniques to obtain collections from debtor parents. Additional legislative changes were made in 1997, 1998, and 1999, but not in 2000, 2001, 2002, or 2003. This report describes several aspects of the revised CSE program and discusses three issues of concern to the 108th Congress — CSE financing, parental access by noncustodial parents, and distribution of child support payments.

China-U.S. Trade Issues (open access)

China-U.S. Trade Issues

U.S.-China economic ties have expanded substantially over the past several years. China is now the third largest U.S. trading partner, its second largest source of imports, and its fourth largest export market. However, U.S.-China commercial ties have been strained by a number of issues, including a surging U.S. trade deficit with China, China's refusal to float its currency, and failure to fully comply with its World Trade Organization (WTO) commitments, especially its failure to provide protection for U.S. intellectual property rights (IPR). This report explores these issues in detail, especially concerning the lack of protection for U.S. IPR.

China's Economic Conditions (open access)

China's Economic Conditions

China’s economy remained relatively healthy in 2002, despite economic slowdowns in other parts of the world. Foreign investment continued to pour into China, and the Chinese government effectively used public spending to boost the economy. However, painful economic reforms will be necessary to keep the economic strong in 2003 and beyond. The recent outbreak in early 2003 of a very contagious virus called SevereAcuteRespiratory Syndrome (SARS) in China appears to have had a short-term negative impact on the Chinese economy.
