Advanced Oil Recovery Technologies for Improved Recovery From Slope Basin Clastic Reservoirs, Nash Draw Brushy Canyon Pool, Eddy County, Nm
The Nash Draw Brushy Canyon Pool (NDP) in southeast New Mexico is one of the nine projects selected in 1995 by the U.S. Department of Energy (DOE) for participation in the Class III Reservoir Field Demonstration Program. The goals of the DOE cost-shared Class Program are to: (1) extend economic production, (2) increase ultimate recovery, and (3) broaden information exchange and technology application. Reservoirs in the Class III Program are focused on slope basin and deep-basin clastic depositional types. Production at the NDP is from the Brushy Canyon formation, a low-permeability turbidite reservoir in the Delaware Mountain Group of Permian, Guadalupian age. A major challenge in this marginal-quality reservoir is to distinguish oil-productive pay intervals from water-saturated non-pay intervals. Because initial reservoir pressure is only slightly above bubble-point pressure, rapid oil decline rates and high gas/oil ratios are typically observed in the first year of primary production. Limited surface access, caused by the proximity of underground potash mining and surface playa lakes, prohibits development with conventional drilling. Reservoir characterization results obtained to date at the NDP show that a proposed pilot injection area appears to be compartmentalized. Because reservoir discontinuities will reduce effectiveness of a pressure maintenance project, the pilot …

Air Traffic Control: FAA Enhanced the Controller-in-Charge Program, but More Comprehensive Evaluation is Needed
A letter report issued by the General Accounting Office with an abstract that begins "Each day, nearly two million passengers on 25,000 flights depend on the Federal Aviation Administration's (FAA) Air Traffic Control (ATC) system to safely reach their destinations. Because the ATC system requires thousands of controllers, each of whom typically manages just a section of airspace or one aspect of an aircraft's takeoff or landing, FAA depends on supervisors to monitor air traffic operations and controllers' workload and performance to ensure that the system is operating safely. In negotiating its 1998 collective bargaining agreement with its controllers' union, FAA agreed to a national plan that would reduce by attrition the number of supervisors who oversee air traffic controllers. To avoid compromising safety, FAA will increasingly have its controllers performing supervisory duties as Controllers-in-Charge (CIC) when supervisors are not present. Nationwide, FAA has selected 8,268 controllers to serve as CICs, which is about 55 percent of its air traffic controller workforce. GAO found that the materials for FAA's CIC training program were through and comprehensive, but FAA has little assurance that the training was effectively presented and achieved its objectives. Although FAA assessed training at a few facilities, the …

AMBIENT PM2.5 SAMPLING AND ANALYSIS
This interim report summarizes detailed findings and conclusions drawn from evaluations of data obtained from the operation of ambient PM{sub 2.5} speciation sites in a geographical area encompassing southeastern Ohio, western Pennsylvania and northwestern West Virginia. The overall goal of this program, called the Upper Ohio River Valley Project (UORVP), is to better understand the relationship between coal-based power system emissions and ambient air quality in the Upper Ohio River Valley region through the collection of chemically resolved or speciated data. A summary of the sampling activities, sample analyses and the correlation and interpretation of data acquired from February 1999 through March of 2001 are reported. Mass and speciated data from urban and rural sources are compared and seasonal variations in PM{sub 2.5} distribution are also examined. Correlations between meteorological parameters and total PM{sub 2.5} mass are also presented.

Anderson Localization of Ballooning Modes, Quantum Chaos and the Stability of Compact Quasiaxially Symmetric Stellarators
The radially local magnetohydrodynamic (MHD) ballooning stability of a compact, quasiaxially symmetric stellarator (QAS), is examined just above the ballooning beta limit with a method that can lead to estimates of global stability. Here MHD stability is analyzed through the calculation and examination of the ballooning mode eigenvalue isosurfaces in the 3-space [s, alpha, theta(subscript ''k'')]; s is the edge normalized toroidal flux, alpha is the field line variable, and q(subscript ''k'') is the perpendicular wave vector or ballooning parameter. Broken symmetry, i.e., deviations from axisymmetry, in the stellarator magnetic field geometry causes localization of the ballooning mode eigenfunction, and gives rise to new types of nonsymmetric eigenvalue isosurfaces in both the stable and unstable spectrum. For eigenvalues far above the marginal point, isosurfaces are topologically spherical, indicative of strong ''quantum chaos.'' The complexity of QAS marginal isosurfaces suggests that finite Larmor radius stabilization estimates will be difficult and that fully three-dimensional, high-n MHD computations are required to predict the beta limit.

A beta test of linear tape-open (LTO) ultrium data storage technology
NERSC is participating in several HPSS (High Performance Storage System) research and development projects as part of the Probe testbed. One of these projects involved beta testing of the IBM 3584 UltraScalable Tape Library, which uses the new ultra-high-density Linear Tape-Open (LTO) Ultrium tape drives. Ultrium tape cartridges have a capacity of up to 300 GB of compressed data, greatly reducing the number of cartridges needed to store massive scientific datasets. NERSC's preliminary performance testing indicates that LTO Ultrium technology, with compatible products and media available from several vendors, may be a viable alternative for computer centers seeking higher-density archival storage media with a small footprint and relatively low cost per drive.

Development of Interfacial Structure in a Confined Air-Water Cap-Turbulent and Churn-Turbulent Flow
The objective of the present work is to study and model the interfacial structure development of air-water two-phase flow in a confined test section. Experiments of a total of 9 flow conditions in a cap-turbulent and churn-turbulent flow regimes are carried out in a vertical air-water upward two-phase flow experimental loop with a test section of 20-cm in width and 1-cm in gap. The miniaturized four-sensor conductivity probes are used to measure local two-phase parameters at three different elevations for each flow condition. The bubbles captured by the probes are categorized into two groups in view of the two-group interfacial area transport equation, i.e., spherical/distorted bubbles as Group 1 and cap/churn-turbulent bubbles as Group 2. The acquired parameters are time-averaged local void fraction, interfacial velocity, bubble number frequency, interfacial area concentration, and bubble Sauter mean diameter for both groups of bubbles. Also, the line-averaged and area-averaged data are presented and discussed. The comparisons of these parameters at different elevations demonstrate the development of interfacial structure along the flow direction due to bubble interactions.

DEVELOPMENT OF OTM SYNGAS PROCESS AND TESTING OF SYNGAS-DERIVED ULTRA-CLEAN FUELS IN DIESEL ENGINES AND FUEL CELLS
This topical report summarizes work accomplished for the Program from January 1 through September 15, 2001 in the following task areas: Task 1--materials development; Task 2--composite element development; Task 3--tube fabrication; Task 4--reactor design and process optimization; Task 5--catalyst development; Task 6--P-1 operation; Task 8--fuels and engine testing; and Task 10--project management. OTM benchmark material, LCM1, exceeds the commercial oxygen flux target and was determined to be sufficiently robust to carry on process development activities. Work will continue on second-generation OTM materials that will satisfy commercial life targets. Three fabrication techniques for composite elements were determined to be technically feasible. These techniques will be studied and a lead manufacturing process for both small and large-scale elements will be selected in the next Budget Period. Experiments in six P-0 reactors, the long tube tester (LTT) and the P-1 pilot plant were conducted. Significant progress in process optimization was made through both the experimental program and modeling studies of alternate reactor designs and process configurations. Three tailored catalyst candidates for use in OTM process reactors were identified. Fuels for the International diesel engine and Nuvera fuel cell tests were ordered and delivered. Fuels testing and engine development work is now underway.

Environmental Protection: Federal Incentives Could Help Promote Land Use That Protects Air and Water Quality
A chapter report issued by the General Accounting Office with an abstract that begins "Americans have become increasingly concerned about the downside of growth and development--increasing dependence on automobiles; worsening traffic congestion; and the loss of farmland, forests, and open space. Some are also concerned that "urban sprawl" can increase air and water pollution, endanger their health, and even threaten their livelihood. Most local transportation planners and state air quality managers do not consider the effects of different land use strategies on air quality. They do not do so principally because nonpoint sources are diffuse and difficult to identify and measure. According to local transportation planners and state air quality managers, federal agencies could help remove barriers to, and provide incentives for, assessing and mitigating the environmental impacts of land use. They proposed actions in the following three key areas: (1) financial incentives for transportation, environmental, and local decisionmakers to collaborate on land use strategies that limit adverse impacts on air and water quality; (2) technical capacity to assess and mitigate land use impacts; and (3) educating the public and local officials about the environmental impacts of their transportation and land use decisions and alternative development strategies that better protect …

FIDDLER CREEK POLYMER AUGMENTATION PROJECT
The Fiddler Creek field is in Weston County, Wyoming, and was discovered in 1948. Secondary waterflooding recovery was started in 1955 and terminated in the mid-1980s with a fieldwide recovery of approximately 40%. The West Fiddler Creek Unit, the focus of this project, had a lower recovery and therefore has the most remaining oil. Before the project this unit was producing approximately 85 bbl of oil per day from 20 pumping wells and 17 swab wells. The recovery process planned for this project involved adapting two independent processes, the injection of polymer as a channel blocker or as a deep-penetrating permeability modifier, and the stabilization of clays and reduction of the residual oil saturation in the near-wellbore area around the injection wells. Clay stabilization was not conducted because long-term fresh water injection had not severely reduced the injectivity. It was determined that future polymer injection would not be affected by the clay. For the project, two adjoining project patterns were selected on the basis of prior reservoir studies and current well availability and production. The primary injection well of Pattern 1 was treated with a small batch of MARCIT gel to create channel blocking. The long-term test was designed for …
