Download or read book Modeling of Heavy Organic Deposition written by and published by . This book was released on 1992 with total page 30 pages. Available in PDF, EPUB and Kindle. Book excerpt: Organic deposition is often a major problem in petroleum production and processing. This problem is manifested by current activities in gas flooding and heavy oil production. The need for understanding the nature of asphaltenes and asphaltics and developing solutions to the deposition problem is well recognized. Prediction technique is crucial to solution development. In the past 5 years, some progress in modeling organic deposition has been made. A state-of-the-art review of methods for modeling organic deposition is presented in this report. Two new models were developed in this work; one based on a thermodynamic equilibrium principle and the other on the colloidal stability theory. These two models are more general and realistic than others previously reported. Because experimental results on the characteristics of asphaltene are inconclusive, it is still not well known whether the asphaltenes is crude oil exist as a true solution or as a colloidal suspension. Further laboratory work which is designed to study the solubility properties of asphaltenes and to provide additional information for model development is proposed. Some experimental tests have been conducted to study the mechanisms of CO2-induced asphaltene precipitation. Coreflooding experiments show that asphaltene precipitation occurs after gas breakthrough. The mechanism of CO2-induced asphaltene precipitation is believed to occur by hydrocarbon extraction which causes change in oil composition. Oil swelling due to CO2 solubilization does not induce asphaltene precipitation.

This book was released on 2009-12-01 with total page 710 pages. Available in PDF, EPUB and Kindle. Book excerpt: Using an applications perspective Thermodynamic Models for Industrial Applications provides a unified framework for the development of various thermodynamic models, ranging from the classical models to some of the most advanced ones. Among these are the Cubic Plus Association Equation of State (CPA EoS) and the Perturbed Chain Statistical Association Fluid Theory (PC-SAFT). These two advanced models are already in widespread use in industry and academia, especially within the oil and gas, chemical and polymer industries. Presenting both classical models such as the Cubic Equations of State and more advanced models such as the CPA, this book provides the critical starting point for choosing the most appropriate calculation method for accurate process simulations. Written by two of the developers of these models, Thermodynamic Models for Industrial Applications emphasizes model selection and model development and includes a useful “which model for which application” guide. It also covers industrial requirements as well as discusses the challenges of thermodynamics in the 21st Century.
Download or read book Asphaltene Precipitation and Its Effects on CO2 based Oil Recovery Processes written by Xiaoqi Wang and published by . This book was released on 2010 with total page 236 pages. Available in PDF, EPUB and Kindle. Book excerpt: During a CO2-based oil recovery process, asphaltene precipitation occurs after a sufficient amount of CO2 is dissolved into the original crude oil under the actual reservoir conditions. Thus, the physicochemical properties of the original crude oil can be dramatically changed due to the in-situ deasphalting process. Accordingly, the deasphalted crude oil becomes less viscous and much easier to be recovered. On the other hand, the precipitated asphaltenes can cause reservoir permeability reduction and wettability alteration, which may greatly hinder the oil recovery.

Available in PDF, EPUB and Kindle. Book excerpt: This is the first volume of a two-volume set of critical reviews of many aspects of both asphaltenes and asphalts and their interrelationship. Asphaltene is invariably present in asphalt or bitumen and other fossil fuel-derived liquids such as coal tar, coal liquefaction products, pyrolyzed shale oil from oil shales, source rock extracts and numerous naturally occurring bituminous substances. The latter include asphaltites, asphaltoids, waxes, and carbonaceous deposits containing a composition of petroleum and coal.The contents cover not only the basic science of asphaltene but also deal with the applications and technology such as upstreams (production, recovery) and down streams (refining, upgrading) of petroleum, and the paving technology and formulation preparation. The main features of the book are: it provides an up-to-date, in-depth review of every aspect of asphaltenes and asphalts; it spans five decades of research and technology of heavy fractions of petroleum; it presents a global view of asphaltene related to exploration production, refining and upgrading.The book will be welcomed as a valuable reference source for petroleum companies, research institutes, refineries, universities and also by individuals dealing with the production, origin, formation, engineering, conversion and catalysis of heavy oil, tar sands and other bitumens materials.
Download or read book Flow Assurance Solids in Oil and Gas Production written by Jon Steinar Gudmundsson and published by CRC Press. This book was released on 2017-09-13 with total page 620 pages. Available in PDF, EPUB and Kindle. Book excerpt: The precipitation and deposition of solids are a major challenge in the production of oil and gas. Flow assurance solids are formed because of unavoidable changes in temperature, pressure and composition of the oil-gas-water flowstream, from reservoir conditions to processing conditions. The advent of subsea production and the increased exploitation of heavy crudes have made flow assurance issues dominant in ensuring efficient and safe exploitation of hydrocarbon assets. Five troublesome flow assurance solids are described in the book: asphaltene, paraffin wax, natural gas hydrate, naphthenate and inorganic scale. These big-five solids are presented in stand-alone chapters. Each chapter is designed to be readable without clutter. Derivations of equations and descriptions of supporting details are given in several appendices. The book is intended for professional engineers and natural scientist working in E&P companies, engineering companies, service companies and specialized companies. An understanding of the big-five solids is required throughout the lifetime of oil and gas assets, from early development to abandonment. The technical, safety and environmental risks associated with deposition problems in near-wellbore formations, production tubing, wellhead equipment, flowlines and processing facilities, are relevant for decisions in the oil and gas industry and in outside regulatory and financial entities.

Available in PDF, EPUB and Kindle. Book excerpt: As conventional oil reserves become depleted, exploration and production trends are towards heavier oils and secondary and tertiary recovery methods, all of which leads to a more acute asphaltene precipitation and deposition problem and serious effects on the economics of oil production. This report gives a comprehensive review of the important factors which affect asphaltene precipitation in petroleum reservoirs and in processing facilities; discusses the nature and characteristics of asphaltenes in crude oil and their molecular and colloidal properties; describes the problems in the reservoirs, well bores and well tubings, processing and transportation equipment; reviews the experiences of the oil industry in tackling the problem and examines several actual field situations; discusses the views in the research community over the nature of asphaltenes in crude oils; details two modelling approaches; and discusses parameters which affect asphaltene adsorption on mineral surfaces. The report also presents a novel method of visualizing in situ asphaltene precipitation from heavy oils with light hydrocarbon gases. Experimental results are reported for the effects of temperature, pressure, composition and phase behaviour on the formation of asphaltene precipitates from heavy crude oils.
Download or read book Asphaltene Stability in Crude Oil During Carbon Dioxide Injection and Its Impact on Oil Recovery written by Sherif Mohamed Hisham Fakher and published by . This book was released on 2019 with total page 132 pages. Available in PDF, EPUB and Kindle. Book excerpt: "Crude oils are usually associated with many compounds, some of which are favorable and others, which are not. One of the most unfavorable components of crude oil that pose severe operational problems and decreases oil production significantly are asphaltenes. These compounds are solids that are homogenized in the crude oil at room temperature but tend to separate from solution when agitated. They can deposit in the reservoir pores, wellbore, and transportation pipelines thus causing severe operational problems and oil recovery reduction. Even though researchers have been studying asphaltenes for more than 100 years, there is still an ambiguity concerning asphaltene structure and characteristics since asphaltenes have no unique structure. This research performed a comprehensive data analysis on both laboratory studies and field cases involving asphaltene in order to provide a generalized guideline on asphaltene properties asphaltene stability. The analysis was based on more than 200 references involving more than 4000 experiments and 19 field studies. Two statistical analysis tools were used, including histograms and boxplots. After determining the factor impacting asphaltene, this research conducted experiments to understand the impact of these factors on asphaltene stability in crude oil during carbon dioxide (CO2) injection in unconventional shale nanopores, since very limited research has been conducted in this area. The research investigated the impact of several factors including pressure, temperature, oil viscosity, pore size, porous media thickness, and heterogeneity on asphaltene precipitation, pore plugging, and oil recovery reduction. A Pareto Plot was also generated to determine the factor that had the strongest impact on asphaltene instability in the crude oil"--Abstract, page iv.

Download or read book Characterization and Properties of Petroleum Fractions written by M. R. Riazi and published by ASTM International. This book was released on 2005 with total page 425 pages. Available in PDF, EPUB and Kindle. Book excerpt: The last three chapters of this book deal with application of methods presented in previous chapters to estimate various thermodynamic, physical, and transport properties of petroleum fractions. In this chapter, various methods for prediction of physical and thermodynamic properties of pure hydrocarbons and their mixtures, petroleum fractions, crude oils, natural gases, and reservoir fluids are presented. As it was discussed in Chapters 5 and 6, properties of gases may be estimated more accurately than properties of liquids. Theoretical methods of Chapters 5 and 6 for estimation of thermophysical properties generally can be applied to both liquids and gases; however, more accurate properties can be predicted through empirical correlations particularly developed for liquids. When these correlations are developed with some theoretical basis, they are more accurate and have wider range of applications. In this chapter some of these semitheoretical correlations are presented. Methods presented in Chapters 5 and 6 can be used to estimate properties such as density, enthalpy, heat capacity, heat of vaporization, and vapor pressure. Characterization methods of Chapters 2-4 are used to determine the input parameters needed for various predictive methods. One important part of this chapter is prediction of vapor pressure that is needed for vapor-liquid equilibrium calculations of Chapter 9.
