This book was released on 2016 with total page 16 pages. Available in PDF, EPUB and Kindle. Book excerpt: General ensemble phase averaged equations for multiphase flows have been specialized for the simulation of the steam assisted gravity drainage (SAGD) process. In the average momentum equation, fluid-solid and fluid-fluid viscous interactions are represented by separate force terms. This equation has a form similar to that of Darcy's law for multiphase flow but augmented by the fluid-fluid viscous forces. Models for these fluid-fluid interactions are suggested and implemented into the numerical code CartaBlanca. Numerical results indicate that the model captures the main features of the multiphase flow in the SAGD process, but the detailed features, such as plumes are missed. We find that viscous coupling among the fluid phases is important. Advection time scales for the different fluids differ by several orders of magnitude because of vast viscosity differences. Numerically resolving all of these time scales is time consuming. To address this problem, we introduce a steam surrogate approximation to increase the steam advection time scale, while keeping the mass and energy fluxes well approximated. This approximation leads to about a 40-fold speed-up in execution speed of the numerical calculations at the cost of a few percent error in the relevant quantities.

This book was released on 2016 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Steam-Assisted Gravity Drainage is an effective approach for recovering heavy oil and bitumen and its essence idea is to introduce steam heat into cold reservoir and reduce oil viscosity. In a typical SAGD process, two horizontal wells were drilled inside the target formation, one is put on the top as steam injection well and another is usually put on the bottom of target formation as oil production well. During SAGD process, a large amount of high pressure high temperature steam is injected into reservoir which occupies a big part of the whole SAGD project cost. The steam pressure and quality decreases during the steam flow inside vertical wellbore because the steam loses its heat through wellbore system to formation due to temperature gradient. And in horizontal wellbore, steam even flow into formation through slotted liner which takes away energy directly. For a SAGD project, the steam pressure and steam quality insides steam injection well are quite important parameters. A high enough quality can offer enough energy for steam chamber to develop and steam pressure will influence the oil production rate, steam trap control as well as ultimate oil recovery. In order to control the cost of SAGD production and offer evidence for steam injection, oil production strategy, the knowledge of steam properties (pressure, temperature, quality) along both vertical and horizontal wellbore are needed. The steam flow inside wellbore is a two phase (dry steam and hot water) flow and the determination of phase void fraction is critical in predicting the pressure loss and heat transfer. The major difference between steam flow inside horizontal wellbore and vertical wellbore is the existence of wall outflow in horizontal wellbore part. This wellbore outflow has a significant effect on wellbore friction as well as flow pattern transition inside wellbore which make it difficult to describe flow pattern in horizontal wellbore by former technology. A model describe steam flow inside wellbore during conventional Steam Assisted Gravity Drainage stage (after the steam chamber has achieved full height and lateral growth becomes the dominant mechanism for recovery) was built and solved in this thesis. A flow pattern independent drift flux model based void fraction correlation was introduced in this thesis in order to overcome the uncertainty problem in determining flow pattern and making is possible to describe steam flow in both vertical wellbore and horizontal wellbore in an unified way. A modified Reis's drainage model was used in this thesis which combined steam flow inside wellbore and steam chamber development inside formation. The steam properties (pressure, quality) distribution along wellbore trajectory were calculated, the effects of basic steam injection parameters (pressure, quality and mass flow rate) were analysed in this thesis. These steam property profiles along wellbore trajectory actually build correlations between wellbore flow and oil production, and will improve the understanding in steam injection strategy adjustment as well as oil production dynamic monitoring.

Download or read book A Numerical Investigation of Metabolic Reductive Dechlorination in DNAPL Source Zones written by John Anthony Christ and published by . This book was released on 2005 with total page 632 pages. Available in PDF, EPUB and Kindle. Book excerpt: Among the most intractable environmental remediation problems are those involving the release of dense non-aqueous phase liquids (DNAPLs), such as chlorinated solvents, to the subsurface. Research efforts have focused on the use of numerical models to investigate reductions in contaminant concentrations due to partial mass removal and improvements in the performance of complementary source zone remediation technologies. Previous numerical investigations, however, have been limited to two-dimensional systems. Furthermore, a lack of models capable of simulating the most promising complementary technology, metabolic reductive dechlorination, has limited its application. This work developed and applied compositional multiphase numerical simulators to examine the influence of dimensionality (two-dimensions versus three-dimensions) on DNAPL source zone simulations and to investigate the benefits of stimulating metabolic reductive dechlorination at a chlorinated ethene-DNAPL contaminated site. Results from the dimensionality investigation showed that the simulation of DNAPL migration, entrapment, and dissolution in two dimensions provided reasonable approximations to the behavior simulated in three dimensions. Commonly employed saturation distribution and mass recovery metrics were approximately equivalent. Flux- averaged concentrations simulated in two dimensions, however, tended to be three to four times higher than those simulated in three dimensions. This difference was attributed to dilution at the down gradient boundary. An alternative metric, mass flux reduction, however, yielded better agreement.

Book excerpt: As organizations realize the benefits of PM, the need to develop effective management tools rises with the increasing complexity of new technologies and processes. Taking a systems approach to accomplishing goals and objectives, Project Management: Systems, Principles, and Applications covers contemporary tools and techniques of PM from an established pedagogical perspective. A project can be simple or complex. In each case, proven PM processes must be followed with a world systems view of the project environment. While on-the-job training is possible for many of the PM requirements, rigorous and formal training must be used. Consequently, PM resources are of high utility. This text fills the void that exists in the availability of PM resources. Although individual books dealing with management principles, optimization models, and computer tools are available, there are few guidelines for the integration of these three areas for PM purposes. This book integrates these areas into a comprehensive guide to PM. It introduces the triad approach to improve the effectiveness of PM with respect to schedule, cost, and performance constraints within the context of systems modeling. It provides details on an integrated systems PM approach that can help diminish the adverse impacts of these issues through good project planning, organizing, scheduling, and control.

Available in PDF, EPUB and Kindle. Book excerpt: Contemporary life is founded on oil – a cheap, accessible, and rich source of energy that has shaped cities and manufacturing economies at the same time that it has increased mobility, global trade, and environmental devastation. Despite oil’s essential role, full recognition of its social and cultural significance has only become a prominent feature of everyday debate and discussion in the early twenty-first century. Presenting a multifaceted analysis of the cultural, social, and political claims and assumptions that guide how we think and talk about oil, Petrocultures maps the complex and often contradictory ways in which oil has influenced the public’s imagination around the world. This collection of essays shows that oil’s vast network of social and historical narratives and the processes that enable its extraction are what characterize its importance, and that its circulation through this immense web of relations forms worldwide experiences and expectations. Contributors’ essays investigate the discourses surrounding oil in contemporary culture while advancing and configuring new ways to discuss the cultural ecosystem that it has created. A window into the social role of oil, Petrocultures also contemplates what it would mean if human life were no longer deeply shaped by the consumption of fossil fuels.
