Development of a cost effective environment compliance technology for stripper brine wells. [Annual] report, January 1, 1993--December 31, 1993

Description: The specific objective of the research is to demonstrate that the characteristics of wastewater from stripper oil wells and marginal gas wells are sufficiently similar to be treated under a standardized treatment methodology, that the environmental impacts of the discharge of treated brines from both stripper oil and marginal gas wells can be adequately regulated, and that the inclusion of marginal gas wells in the same category as stripper oil wells is appropriate, especially for wells operating in the Appalachian Basin. The work accomplished during 1992 for both the field-scale and the laboratory-scale treatment facilities focused on iron removal from the field and synthetic brines. The laboratory work also included single-element kinetics studies to determine the effect of one metal on another with respect to the rates of the various reactions. The laboratory process studies investigated such parameters as the sand bed thickness, the temperature of the system, the angle of the aeration unit, and the presence of the retention tank. All of these laboratory parametric studies provided insight into how each component of the treatment process contributes to the removal of iron from the synthetic brine. Similar studies have begun for investigating copper removal effectiveness. As for the field work, several brines from sandstone formations in Pennsylvania, such as the Red Valley brine and the Warren brine, were treated with the field unit. The results of our analyses indicated that the field unit effectively removes iron from these field brines.

An experimental and theoretical study to relate uncommon rock/fluid properties to oil recovery. Quarterly report, January 1, 1993--March 31, 1993

Description: The overall objectives of the project are: To develop a better understanding of some important but not really well investigated rock/pore properties such as: tortuosity, pore-size distribution, surface area, and wettability, and a better insight on capillary pressure variation with respect to wettability and pore geometry of sandstone and limestone. To improve the understanding of fluid flow in porous media under conditions of secondary and tertiary recovery through the laboratory study of the performance of enhanced recovery methods such as waterflooding. To develop empirical relationships between residual oil saturation and oil recovery at breakthrough and the uncommon rock/pore properties. Develop relationships between residual oil saturation and ultimate oil recovery at floodout and the uncommon rock/pore properties for the different porous media. Furthermore, variations of irreducible water saturation, porosity and absolute permeability with respect to the uncommon rock/pore properties, residual oil saturation and oil recovery will be investigated. During the current quarter, new empirical mercury recovery efficiency and permeability correlations for sandstones were developed. The correlations were developed by utilizing the 450 core-plugs data that were previously obtained from the mercury porosimetry analyses for sandstones.

Development of a cost-effective environmental compliance technology for stripper well brines. Quarterly report, October 1, 1993--December 31, 1993

Description: In order to demonstrate to the EPA that brines from both stripper oil and marginal gas wells in the Appalachian Basin are capable of being treated and disposed of by discharge to streams in an environmentally safe manner, the existing research effort on stripper oil well brines will be continued and expanded to examine the range of brines produced from marginal gas wells. The specific object of the research is to demonstrate that the characteristics of wastewater from stripper oil wells and marginal gas wells are sufficiently similar to be treated under a standardized treatment methodology, that the environmental impacts of the discharge of treated brines from both stripper oil and marginal gas wells can be adequately regulated, and that the inclusion of marginal gas wells in the same category as stripper oil wells is appropriate, especially for wells operating in the Appalachian Basin.

Delta-t protocol specification: working draft

Description: This document is one of a series describing protocols associated with the Livermore Interactive Network Communication System (LINCS) hierarchical architecture. At the heart of LINCS is its basic interprocess communication (LINCS-IPC) service. LINCS-IPC defines a reliable, flow controlled, full duplex, uninterpreted, labeled bit stream communication service. LINCS-IPC is level 4 in the LINCS architecture. Level 3 of LINCS is the Network layer defining an internetwork datagram type service. LINCS-IPC interfaces to User processes that utilize higher level syntactic and semantic conventions for process interaction. The transport service provided by the Delta-t protocol can be considered a sublayer of the LINCS-IPC layer. Delta-t augments the Network level service as required to support LINCS-IPC. This document specifies the services provided by the Delta-t protocol to support LINCS-IPC, the operation of Delta-t, and the services Delta-t requires of the Network level. This document was written to be self-contained but the reader will find it useful to have available for reference the LINCS-IPC and LINCS DeltaGram Network layer protocol specifications. Implementations are underway in Pascal for the PDP-11 running under RT11 and RX11, in BLISS for the VAX running under VMS, in MODEL for the CRAY-1 and CDC 7600 running under NLTSS and LTSS, and for the SEL 32/75 running under PORT.

Detection of Shielded Nuclear Material in a Cargo Container

Description: The Idaho National Laboratory, along with Los Alamos National Laboratory and the Idaho State University’s Idaho Accelerator Center, are developing electron accelerator-based, photonuclear inspection technologies for the detection of shielded nuclear material within air-, rail-, and especially, maritime-cargo transportation containers. This paper describes a developing prototypical cargo container inspection system utilizing the Pulsed Photonuclear Assessment (PPA) technology, incorporates interchangeable, well-defined, contraband shielding structures (i.e., "calibration" pallets) providing realistic detection data for induced radiation signatures from smuggled nuclear material, and provides various shielded nuclear material detection results. Using a 4.8-kg quantity of depleted uranium, neutron and gamma-ray detection responses are presented for well-defined shielded and unshielded configurations evaluated in a selected cargo container inspection configuration. © 2001 Elsevier Science.

An Enterprise Information Architecture: A Case Study for Decentralized Organizations

Description: As enterprises become increasingly information based, making improvements in their information activities is a top priority to assure their continuing competitiveness. A key to achieving these improvements is developing an Enterprise Information Architecture (EIA). An EIA can be viewed as a structured set of multidimensional interrelated elements that support all information processes. The current ad hoc EIAs in place within many enterprises can not meet their future needs because of a lack of a coherent framework, incompatibilities, missing elements, few and poorly understood standards, uneven quality and unnecessary duplications. This paper discusses the EIA developed at Lawrence Livermore National Laboratory as a case study, for other information based enterprises, particularly those with decentralized and autonomous organization structures and cultures. While the architecture is important, the process by which it is developed and sustained over time is equally important. This paper outlines the motivation for an EIA and discusses each of the interacting elements identified. It also presents an organizational structure and processes for building a sustainable EIA activity.

The parallel I/O architecture of the High Performance Storage System (HPSS)

Description: Rapid improvements in computational science, processing capability, main memory sizes, data collection devices, multimedia capabilities and integration of enterprise data are producing very large datasets (10s-100s of gigabytes to terabytes). This rapid growth of data has resulted in a serious imbalance in I/O and storage system performance and functionality. One promising approach to restoring balanced I/O and storage system performance is use of parallel data transfer techniques for client access to storage, device-to-device transfers, and remote file transfers. This paper describes the parallel I/O architecture and mechanisms, Parallel Transport Protocol, parallel FIP, and parallel client Application Programming Interface (API) used by the High Performance Storage System (HPSS). Parallel storage integration issues with a local parallel file system are also discussed.
