This book was released on 2004 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Petroleum exploration and development are capital intensive and smart economic decisions that need to be made to profitably extract oil and gas from the reservoirs. Accurate quantification of uncertainty in production forecasts will help in assessing risk and making good economic decisions. This study investigates the effect of combining dynamic data with the uncertainty in static data to see the effect on estimates of uncertainty in production forecasting. Fifty permeability realizations were generated for a reservoir in west Texas from available petrophysical data. We quantified the uncertainty in the production forecasts using a likelihood weighting method and an automatic history matching technique combined with linear uncertainty analysis. The results were compared with the uncertainty predicted using only static data. We also investigated approaches for best selecting a smaller number of models from a larger set of realizations to be history matched for quantification of uncertainty. We found that incorporating dynamic data in a reservoir model will result in lower estimates of uncertainty than considering only static data. However, incorporation of dynamic data does not guarantee that the forecasted ranges will encompass the true value. Reliability of the forecasted ranges depends on the method employed. When sampling multiple realizations of static data for history matching to quantify uncertainty, a sampling over the entire range of realization likelihoods shows larger confidence intervals and is more likely to encompass the true value for predicted fluid recoveries, as compared to selecting the best models.

Available in PDF, EPUB and Kindle. Book excerpt: With the expansion of new technologies, materials, and the design of complex systems, the expectations of society upon engineers are becoming larger than ever. Engineers make critical decisions with potentially high adverse consequences. The current political, societal, and financial climate requires engineers to formally consider the factors of uncertainty (e.g., floods, earthquakes, winds, environmental risks) in their decisions at all levels. Uncertainty Modeling and Analysis in Civil Engineering provides a thorough report on the immediate state of uncertainty modeling and analytical methods for civil engineering systems, presenting a toolbox for solving problems in real-world situations. Topics include Neural networks Genetic algorithms Numerical modeling Fuzzy sets and operations Reliability and risk analysis Systems control Uncertainty in probability estimates This compendium is a considerable reference for civil engineers as well as for engineers in other disciplines, computer scientists, general scientists, and students.

Download or read book Some Implications for Monetary Policy of Uncertain Exchange Rate Pass Through written by Mr.Benjamin Hunt and published by International Monetary Fund. This book was released on 2003-03-04 with total page 38 pages. Available in PDF, EPUB and Kindle. Book excerpt: The paper uses MULTIMOD to examine the implications of uncertain exchange rate pass-through for the conduct of monetary policy. From the policymaker's perspective, uncertainty about exchange rate pass-through implies uncertainty about policy multipliers and the impact of state variables on stabilization objectives. When faced with uncertainty about the strength of exchange rate pass-through, policymakers will make less costly errors by overestimating the strength of pass-through rather than underestimating it. The analysis suggests that pass-through uncertainty of the magnitude considered does not result in efficient policy response coefficients that are smaller than those under certainty.

Download or read book The Measurement of Environmental and Resource Values written by A. Myrick Freeman III and published by Routledge. This book was released on 2014-06-05 with total page 523 pages. Available in PDF, EPUB and Kindle. Book excerpt: The first edition of this important work was the winner of the 2002 Publication of Enduring Quality award by the Association of Environmental and Resource Economists. The continuing premise for the book is that estimates of the economic values of environmental and natural resource services are essential for effective policy-making. As previous editions, the third edition, which includes two additional co-authors, presents a comprehensive treatment of the theory and methods involved in estimating environmental benefits. Researchers, policy-makers, and practitioners will welcome the work as an up-to-date reference on recent developments. Students will gain a better understanding of the contribution that economics as a discipline can make to decisions concerning pollution control and human health, recreation, environmental amenities, and other critical issues concerning the way we use and interact with environmental and natural resource systems. To reflect recent progress in both the theory and practice of non-market valuation, the third edition includes more details on empirical approaches to measurement, expanded discussion of the reasons for divergence between "willingness to pay" and "willingness to accept compensation," and increased coverage of econometric issues encountered in estimation. In keeping with its cutting edge orientation, it also includes more discussion of survey design, equilibrium sorting models, and the implications of behavioral economics for welfare measurements and benefit cost analysis.

Download or read book District Heating and Cooling Networks written by Antonio Colmenar Santos and published by MDPI. This book was released on 2020-05-12 with total page 270 pages. Available in PDF, EPUB and Kindle. Book excerpt: Conventional thermal power generating plants reject a large amount of energy every year. If this rejected heat were to be used through district heating networks, given prior energy valorisation, there would be a noticeable decrease in the amount of fossil fuels imported for heating. As a consequence, benefits would be experienced in the form of an increase in energy efficiency, an improvement in energy security, and a minimisation of emitted greenhouse gases. Given that heat demand is not expected to decrease significantly in the medium term, district heating networks show the greatest potential for the development of cogeneration. Due to their cost competitiveness, flexibility in terms of the ability to use renewable energy resources (such as geothermal or solar thermal) and fossil fuels (more specifically the residual heat from combustion), and the fact that, in some cases, losses to a country/region’s energy balance can be easily integrated into district heating networks (which would not be the case in a “fully electric” future), district heating (and cooling) networks and cogeneration could become a key element for a future with greater energy security, while being more sustainable, if appropriate measures were implemented. This book therefore seeks to propose an energy strategy for a number of cities/regions/countries by proposing appropriate measures supported by detailed case studies.
