RESERVOIR CHARACTERIZATION OF THE LOWER GREEN RIVER FORMATION, SOUTHWEST UINTA BASIN, UTAH (open access)

RESERVOIR CHARACTERIZATION OF THE LOWER GREEN RIVER FORMATION, SOUTHWEST UINTA BASIN, UTAH

The +2000-foot-thick (600-m), Tertiary-aged lacustrine deposits of the Middle and Lower Members of the Green River Formation contain the primary oil-producing reservoirs in the southwest Uinta Basin. The authors developed a log-based correlation scheme by identifying what they interpret as depositional cycles on the gamma-ray and resistivity logs of several wells. Regional cross sections were constructed and cycle boundaries revised as needed. The cycles typically range from 50 to 100 feet (15-30 m) thick. The regional correlation scheme will be used to improve their knowledge of the depositional patterns and distribution of productive intervals in the southwest Uinta Basin. Currently, each operator uses a different terminology for many of the same intervals. A regional log-based correlation scheme based on depositional cycles should make it easier to relate subsurface data to the outcrop where depositional environments and lateral continuity of the reservoir rocks can be studied in greater detail. The correlation scheme uses an alpha-numeric nomenclature avoiding local field or facies names that are difficult to use regionally. The nomenclature has three primary levels: (1) MGR or LGR for Middle or Lower Green River, respectively, (2) MGR1 through MGR18 and LGR1 through LGR3 for the different cycles in each member, and …

ENRAF Series 854 Advanced Technology Gauge (ATG) Acceptance Test Procedure (open access)

ENRAF Series 854 Advanced Technology Gauge (ATG) Acceptance Test Procedure

This procedure provides acceptance testing for Enraf Series 854 level gauges used to monitor levels in Hanford Waste Storage Tanks. The test will verify that the gauge functions according to the manufacturer's instructions and specifications and is properly setup prior to being delivered to the tank farm area. This ATP does not set up the gauge for any specific tank, but is generalized to permit testing the gauge prior to installation package preparation.

Groundwater Monitoring Plan for the Nonradioactive Dangerous Waste Landfill (open access)

Groundwater Monitoring Plan for the Nonradioactive Dangerous Waste Landfill

The Nonradioactive Dangerous Waste Landfill (NRDWL), which received nonradioactive hazardous waste between 1975 and 1985, is located in the central Hanford Site (Figure 1.1) in southeastern Washington State. The Solid Waste Landfill, which is regulated and monitored separately, is adjacent to the NRDWL. The NRDWL is regulated under the Resource Conservation and Recovery Act of 1976 (RCRA) and monitored by Pacific Northwest National Laboratory. Monitoring is done under interim-status, indicator-evaluation requirements (WAC 173-303 and by reference, 40 CFR 265.92). The well network includes three upgradient wells (one shared with the Solid Waste Landfill) and six downgradient wells. The wells are sampled semiannually for contaminant indicator parameters and site-specific parameters and annually for groundwater quality parameters.

Decay heat removal by natural convection - the RVACS system. (open access)

Decay heat removal by natural convection - the RVACS system.

In conclusion, this work shows that for sodium coolant the reactor vessel auxiliary cooling system (RVACS) is an effective passive heat removal system if the reactor power does not exceed about 1600 MW(th). Its effectiveness is limited by the effective radiative heat transfer coefficient in the inner gap. In a lead cooled system, economic considerations may impose a lower limit.

Terascale spectral element algorithms and implementations. (open access)

Terascale spectral element algorithms and implementations.

We describe the development and implementation of an efficient spectral element code for multimillion gridpoint simulations of incompressible flows in general two- and three-dimensional domains. We review basic and recently developed algorithmic underpinnings that have resulted in good parallel and vector performance on a broad range of architectures, including the terascale computing systems now coming online at the DOE labs. Sustained performance of 219 GFLOPS has been recently achieved on 2048 nodes of the Intel ASCI-Red machine at Sandia.

Stability of spheromaks compressed by liquid walls (open access)

Stability of spheromaks compressed by liquid walls

We consider Rayleigh-Taylor instability of the liquid-plasma interface of a spheromak ignited by slow compression discussed previously. We conclude that instability may indeed occur despite the stabilizing influence of magnetic shear in the spheromak. If it occurs, instability would be greatest for modes concentrated toward the midplane. As for the cylindrical LINUS configuration, rotation about the geometric axis would stabilize these modes, but at the price of roughly doubling the input energy and reducing the gain. However, even in the absence of rotation, in a sphere instability occurs only at the end of compression near the stagnation point. Revised estimates of the fusion energy gain taking this brief period of instability into account still give, within the uncertainties, a gain G {approx} 20 for our earlier example with an input energy of 150 MJ and fusion yield of 3 GJ.

CP Violation and B Physics (open access)

CP Violation and B Physics

This is a quick review of CP non-conservation in B physics. Several methods are described for testing the Kobayashi-Maskawa single phase origin of CP violation in B decays, pointing out some limitations due to hadronic uncertainties. A few characteristic signatures of new physics in B decay asymmetries are listed.

Financing Solar Energy Systems with Energy Savings Performance Contracts in the Federal Sector: Results of a Survey on Barriers (open access)

Financing Solar Energy Systems with Energy Savings Performance Contracts in the Federal Sector: Results of a Survey on Barriers

This report summarizes the findings of an investigation into financing solar energy systems for the Federal sector. The objectives of the investigation were (1) to identify the barriers that impede companies from using Energy Savings Performance Contracts (ESPCs) to develop solar energy projects for Federal facilities, and (2) to clarify the impacts of Federal contracting requirements on energy service companies' use of ESPCs. Twenty-four representatives of energy service companies agreed to be interviewed. Their responses indicate that these are the primary barriers to greater use of ESPCs: the relatively long payback periods for investments in solar technologies; the length of the ESPC process; the cost of certain contractual requirements regarding wages and financing; and a lack of knowledge about the actual cost and reliability of solar systems. The report proposes a number of actions the government could take to remove these barriers, including (1) streamlining and shortening the ESPC process and (2) doing more to inform both government agencies and energy service companies about the costs and benefits of solar systems.
