Summary To realize the potential of the latest high-performance computing (HPC) architectures for reservoir simulation, scalable linear solvers are necessary. We describe a parallel algebraic multiscale solver (AMS) for the pressure equation of heterogeneous reservoir models. AMS is a two-level algorithm that uses domain decomposition with a localization assumption. In AMS, basis functions, which are local (subdomain) solutions computed during the setup phase, are used to construct the coarse-scale system and grid-transfer operators between the fine and coarse levels. The solution phase is composed of two stages: global and local. The global stage involves solving the coarse-scale system and interpolating the solution to the fine grid. The local stage involves application of a smoother on the fine-scale approximation. The design and implementation of a scalable AMS on multicore and many-core architectures, including the decomposition, memory allocation, data flow, and compute kernels, are described in detail. These adaptations are necessary to obtain good scalability on state-of-the-art HPC systems. The specific methods and parameters, such as the coarsening ratio (Cr), basis-function solver, and relaxation scheme, have significant effects on the asymptotic convergence rate and parallel computational efficiency. The balance between convergence rate and parallel efficiency as a function of Cr and the local stage parameters is analyzed in detail. The performance of AMS is demonstrated using heterogeneous 3D reservoir models, including geostatistically generated fields and models derived from SPE10 (Christie and Blunt 2001). The problems range in size from several million to 128 million cells. AMS shows excellent behavior for handling fixed-size problems as a function of the number of cores (so-called strong scaling). Specifically, for a 128-million-cell problem, a ninefold speedup is obtained on a single-node 12-core shared-memory architecture (dual-socket multicore Intel Xeon E5-2620-v2), and more than 12-fold on a single-node 20-core shared-memory architecture (dual-socket multicore Intel Xeon E5-2690-v2). These are encouraging results given the limited memory bandwidth that cores can share within a single node, which tends to be the major bottleneck for truly scalable solvers. We also compare the robustness and performance of our method with the parallel system algebraic mutligrid (SAMG) solver (Stüben 2012) from Fraunhofer SCAI.

Abstract The upstream oil & gas industry has been contending with massive data sets and monolithic files for many years, but "Big Data"—that is, the ability to apply more sophisticated types of analytical tools to information in a way that extracts new insights or creates new forms of value—is a relatively new concept that has the potential to significantly re-shape the industry. Despite the impressive amount of value that is being realized by Big Data technologies in other parts of the marketplace, however, much of the data collected within the oil & gas sector tends to be discarded, ignored, or analyzed in a very cursory way. This paper examines existing data management practices in the upstream oil & gas industry, and compares them to practices and philosophies that have emerged in organizations that are leading the Big Data revolution. The comparison shows that, in companies that are leading the Big Data revolution, data is regarded as a valuable asset. The presented evidence also shows, however, that this is usually not true within the oil & gas industry insofar as data is frequently regarded there as descriptive information about a physical asset rather than something that is valuable in and of itself. The paper then discusses how upstream oil & gas companies could potentially extract more value from data, and concludes with a series of specific technical and management-related recommendations to this end.

Introduction Employee retention, rising health care costs, addressing an aging population, and a desire for employees to be "healthier because they work at Intel" all influenced Intel's decision to create a company sponsored health and wellness program. Based on a vision of developing a culture where employees and their families are healthy, productive, and engaged in living wellness-soriented lifestyles every day, employees are now inspired and motivated to take action toward achieving their best possible health and quality of life. Intel's Health for Life wellness program includes onsite biometrics, annual health risk assessments, fitness programs, wellness seminars, flu prevention, and personal wellness coaching. This presentation shares how Intel used a process to pilot and deploy an effective global health and wellness program because "it's the right thing to do". Pilot Study One of our main program components is a Health Risk Assessment (HRA) provided online by a major healthcare provider. Results of the HRA are used to drive health and wellness programs (all data reported to Intel from the HRA is in aggregate form, no individual employee information is given to Intel). Upon close examination of the aggregate HRA results, we noted that those who participated in the HRA had several missing data points (e.g., blood pressure, blood lipids & glucose results, and body fat percentage) that are important in assessing lifestyle and medical risk factors. Therefore, we did not believe the information we received from the HRA gave an accurate picture of the health risks of our employees. We therefore had two assumptions:We did not have accurate results from the HRA; and Employees are interested in knowing about their health risks. Our Health for Life program development began with a pilot study at our five main U.S. manufacturing sites. We provided free on-site lab work (fasting cholesterol, triglycerides, and glucose) and biometrics (blood pressure, pulse, weight, height, and body fat percentage) during hours that were convenient for employees. Employees received their lab results a few days later via interoffice mail. An e-mail was then sent to them with a link to the online HRA and directions to enter their lab and biometric data and complete their HRA. After completing their HRA, employees were scheduled for their 30-minute confidential, one-on-one counseling session with an occupational health registered nurse. These sessions were used to review the employees' results and offer ways to manage their health risks. After the session we e-mailed employees links to additional resources and a link to a survey on the process. Of those who responded to the survey, 96% were satisfied or very satisfied with the pilot. We also asked employees for their comments on how to improve the process and incorporated their suggestions into overall program. We compared the results of those employees who participated in the pilot study with those who did not participate and saw a statistically significant increase in risk factors of elevated blood pressure, serum lipids, and glucose.

Introducción Como un emigrante de tercera generación el crecer y trabajar con trabajadores emigrantes, me ha dado la oportunidad de vivir, observar y ser testigo de ver como nuestra gente sufre y constantemente se lastima durante el proceso de obtener el Sueno Americano. Claramente recuerdo los dÃas cuando yo, mi familia y gente de mi mis cultura vivÃan en los campos, cocinábamos con hogueras y si tenÃamos suerte con una estufita de gas licuado, dormÃamos en casas de campana, nos bañábamos en canales de color medio verdosos cercas de los campos de trabajo y jugamos en los campos. Rápidamente empecé a observar como nuestra cultura empezó a obtener trabajos en las manufacturas, las industrias industriales, construcción y hasta trabajos a nivel profesionales. Solo tenÃamos una meta en la mente: la cual era trabajar duro y como fuera posible en nuestros trabajos, aunque nos lastimáramos durante el proceso del trabajo. Observa la foto "A" lo cual nos muestra que no importa lo que se tenga que hacer se hace para terminar el trabajo. Lo hacÃamos porque tenÃamos una mentalidad: la cual era asegurarnos de complacer a nuestra gerencia para lograr nuestra meta, lo cual era mantener nuestro trabajo y ganar dinero para mejorar la vida de nuestras familias. Nuestra presentación de Barreras Culturales Hacia La Seguridad recalca principalmente en la cultura Mexicana, donde uno de los autores desciende de. Al comienzo de la presentación el presentador proveerá como históricamente comenzó el proyecto de las Barreras Culturales Hacia La Seguridad, y como experimentamos y/o pusimos a prueba el material con La Corporación de Intel, Costa Rica, México, y agencias locales del gobierno tales como: La Administración de Compensación de New Mexico, El Consulado de México de Nuevo Mexico y OSHA. Se hablara un resumen de la cultura, en donde se tocara los aspectos de la educación, sociológicos, y económicos. En seguida nuestra presentación le da seguimiento a recomendaciones en como crear confianza y comunicación a lo largo de recomendaciones hacia el empleador mientras trabajas con los empleados. Durante el cuerpo de la presentación el presentador cubrirá dos módulos, los cuales fueron desarrollados para entrenar al empleador y los empleados. Adicionalmente técnicas para planear con seguridad, como transmitir gráficamente, y demostraciones visuales para transmitir nuestro masaje al oyente. Una discusión de equipo de trabajo, un dialogo abierto, y forum abiertos son también presentados a la audiencia. Al final de la presentación un resumen del programa de seguridad será repasado para enseñarles como las técnicas mencionadas pueden ser incorporadas para entrenar a sus empleados emigrantes para valorar su seguridad y la de sus co-empleados. En conclusión un resumen con todos los puntos claves respecto a las Barreras Culturales Hacia La Seguridad serán repasados. El método de presentación usado será presentado por medio de una presentación en Power Point, inclusive fotos por uno o más de los co-autores del documento.

Introduction Being a third generation growing up and working with migrant workers has given me the opportunity to live, experience and see how our people suffer and constantly get injured during the process of achieving the America dream. I clearly remember the days when my family and I, and those of my culture used to live in the fields, cook out of a fire (we were lucky we had propane stove), sleep in a tent, take showers on green-looking canals near the fields, and play in the orchards. I witnessed how rapidly our culture began to obtain various jobs, such as those in manufacturing, industrial, commercial, construction and even professional positions. We had one goal in mind when working on the jobs: to try as hard as possible to complete them to best of our knowledge, even if we hurt ourselves during the process of the job. See picture "A" which illustrates that no matter what it takes the job will be completed. We do it because we have the mentality to please our superior management to obtain our goal, keeping a job and earning money to better the life of our families. Culture Barriers to Safety emphasizes the cultural background, primarily the Mexican culture where one of the authors descends from. At the beginning of the presentation the speaker provides a background on how the culture barriers to safety began, and how we have experienced and/or tested the material with Intel Corporation in Costa Rica and Mexico, and local governmental agencies such as NM Workers Compensation, OSHA and the Mexican council. The cultural background includes detailed discussion of the educational, sociological, personal, and economic factors. Our presentation follows with recommendations on how to build trust and communication, along with recommendations for the employer when working with the employees. During the body of the presentation the speaker will cover two modules that were developed to train employers and employees. Techniques such as planning for safety, as well as graphics and visual demonstrations are used to get our message across. A discussion on teamwork, open dialogue and open forums are also presented to the audience. Toward the end of the presentation an overview of a safety program will be discussed to show how the above techniques can be employed for training migrant workers to value their safety and that of their co-workers. In conclusion, a summary with all the key points of the culture barriers to safety will be re-stated. The presentation method employed will be delivery of a Power Point presentation, inclusive of photographs, by one or both of the co-authors of the paper.
Abstract Water conservation is becoming a greater issue with many industries and in different areas of the country. In order to assure success in any conservation program, the affects on the processes the water services should be fully understood. Interactions between different projects must be factored into decisions concerning the conservation program. This paper discusses one such program and some of the considerations that had to be addressed. INTRODUCTION to rinse contaminants from the microchips in production to produce ultrapure water (UPW)for the rinse processes cooling towers boilers scrubbers landscape irrigation. Large quantities of water are used in the production of semiconductors. Water is used to in the following manners:The ratio of the different uses will be site specific due to variations in climatic conditions, water qualities, process steps and size of the production (fab) operation. Water conservation at the Rio Rancho facility became a priority because of plans to build a new fab on the site. Projected water use for the new fab along with the two other existing fab operations was as high as 10 million gallons per day (40,000 mper day). In 1993, it was determined that the city of Rio Rancho would not be able to meet the projected increase in water use. Also in 1993, the United States Geological Survey (USGS) released a report that indicated the water level in the local aquifer had been dropping during the period of 1960-1992. Company officials petitioned the New Mexico State Engineer’s Office for water rights to support the site expansion. Water rights were granted to the company with the contingency that water conservation be made a priority. The company agreed to a targeted 39% water conservation level by 1999. To date, conservation efforts have achieved a water conservation level of approximately 35% (annual average). WATER CONSERVATION TERMINOLOGY Water conservation has been approached in three manners- reduction, reclamation and recycling. Reduction means to perform the same job with less water than before. Reclamation means to reuse a wastewater in some operation other than its original use. Recycling means to reuse a wastewater in the same service as its original use. The following briefly describes the specific projects to be discussed in the paper. Treated Industrial Water (TIW) - This is a reclaim system which uses the combined process wastewaters and chemicals from three fab operations. The wastewater is collected into a central system, treated for control of pH, foam and biological activity prior to being distributed to some of the cooling towers and scrubbers on the site. A TIW analysis is included in Table #1. Industrial Reclaim Water (IRW)- This is also a reclaim system used for cooling tower and scrubber makeup. It is similar in nature to the TIW system except certain waste streams and contaminants have been diverted yielding a cleaner water source (Ultrapure Recycle Water or URW). Reverse osmosis reject is blended with wastewater from the fab to provide additional volume and improved chemical characteristics.
