Available in PDF, EPUB and Kindle. Book excerpt: Controlled salinity water flooding has shown to be a promising enhanced recovery method that can reduce residual oil saturation. Currently, no unified criterion exists to explain the mechanisms by which this form of water-flooding leads to higher oil recovery. Research on the subject attributes the results to complex rock/fluid and fluid/fluid interactions. Wettability alteration is used to characterize rock/fluid interactions, while rheology can characterize fluid/fluid interactions in dynamical systems. High interfacial viscoelasticity has shown to suppress snap- off, improve oil phase connectivity, and consequently increase oil recoveries. However, the relationships between the surface-active components of the crude oil and the brine ions remains unclear. Regarding components in crude oil, asphaltenes have been reported to contribute to interface strengthening, while naphthenic acids and other organic acids induce softening. On the other hand, mainly polyvalent cations, also called active ions, can induce a more rigid interface. The effect of anions on the phenomena has gone essentially unexplored. Tensiometry and rheology techniques were used to evaluate the effect of different anions on the conformation of the crude oil/brine interface, both in low- and high-salinity regimes. Experiments using pendant drop tensiometers and dilatational rheometers show that as the size and complexity of the anions increase, the interfacial film becomes more resistant to deformation. In addition, a liquid bridge technique was used to estimate the stability of the crude oil/water interface. A good connection with rheology and tensiometry results was established. Finally, further research is needed to clarify the mechanisms by which this occurs.

Book Synopsis Evaluation of the Effects of Brine Chemistry Salinity on Gibbs Oil Interfacial Tension and Dynamic Moduli Properties by : Amy Michelle Brandvik
Download or read book Evaluation of the Effects of Brine Chemistry Salinity on Gibbs Oil Interfacial Tension and Dynamic Moduli Properties written by Amy Michelle Brandvik and published by . This book was released on 2010 with total page 134 pages. Available in PDF, EPUB and Kindle. Book excerpt: The FTA 1000 oscillating pendant drop apparatus was modified and used to measure the dilational elasticity modulus and interfacial tension of Gibbs crude oil in different dilutions of NaCl and CaCl2 brines. The brine samples were diluted by 100, 500 and 1000 parts from an initial ionic strength of 0.6724M. The crude oil samples were not diluted, but used at full strength. Measurements were conducted at both 25 and 50°C to understand the effects of crude oil viscosity on dilational elasticity modulus values. Results showed that although dynamic moduli values for Gibbs crude oil depended on temperature, aging time, brine composition and brine ionic strength, interfacial tension and rate of changes of interfacial tension values displayed little variations. The interfaces formed from the monovalent brines appeared to be slightly more rigid, although all interfaces tested were highly elastic. The elastic nature of oil-water interfaces immersed in both monovalent and divalent brines were similar at the initial ionic strength of 0.6724M, but diverged with brine dilution. Diluted divalent brines affected the Gibbs oil interface formation and dynamic moduli properties more strongly that diluted monovalent brines, and lead to increased interface growth. It appears that there may exist a kinetic rate of film formation that is affected by temperature during aging. Finally, as the dynamic moduli created a wide array of results while interfacial tension changed little, dynamic modulus values are an important consideration for any oil recovery system, as fluids move in a dynamic fashion. The outcomes of this research may explain related stability results, namely that lower ionic strength brines form more stable emulsions for Gibbs field oil as well as for other crude oils previously examined. These results might impact the interpretation of several enhanced oil recovery processes.

This book was released on 2016-03-28 with total page 392 pages. Available in PDF, EPUB and Kindle. Book excerpt: Colloid and Surface Chemistry is a subject of immense importance and implications both to our everyday life and numerous industrial sectors, ranging from coatings and materials to medicine and biotechnology. How do detergents really clean? (Why can't we just use water?) Why is milk "milky"? Why do we use eggs so often for making sauces? Can we deliver drugs in better and controlled ways? Coating industries wish to manufacture improved coatings e.g. for providing corrosion resistance, which are also environmentally friendly i.e. less based on organic solvents and if possible exclusively on water. Food companies want to develop healthy, tasty but also long-lasting food products which appeal to the environmental authorities and the consumer. Detergent and enzyme companies are working to develop improved formulations which clean more persistent stains, at lower temperatures and amounts, to the benefit of both the environment and our pocket. Cosmetics is also big business! Creams, lotions and other personal care products are really just complex emulsions. All of the above can be explained by the principles and methods of colloid and surface chemistry. A course on this topic is truly valuable to chemists, chemical engineers, biologists, material and food scientists and many more.

Download or read book Chemical Enhanced Oil Recovery written by Patrizio Raffa and published by Walter de Gruyter GmbH & Co KG. This book was released on 2019-07-22 with total page 277 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book aims at presenting, describing, and summarizing the latest advances in polymer flooding regarding the chemical synthesis of the EOR agents and the numerical simulation of compositional models in porous media, including a description of the possible applications of nanotechnology acting as a booster of traditional chemical EOR processes. A large part of the world economy depends nowadays on non-renewable energy sources, most of them of fossil origin. Though the search for and the development of newer, greener, and more sustainable sources have been going on for the last decades, humanity is still fossil-fuel dependent. Primary and secondary oil recovery techniques merely produce up to a half of the Original Oil In Place. Enhanced Oil Recovery (EOR) processes are aimed at further increasing this value. Among these, chemical EOR techniques (including polymer flooding) present a great potential in low- and medium-viscosity oilfields. • Describes recent advances in chemical enhanced oil recovery. • Contains detailed description of polymer flooding and nanotechnology as promising boosting tools for EOR. • Includes both experimental and theoretical studies. About the Authors Patrizio Raffa is Assistant Professor at the University of Groningen.

He (co)authored about 40 articles in peer reviewed journals. Pablo Druetta works as lecturer at the University of Groningen (RUG) and as engineering consultant. He received his Ph.D. from RUG in 2018 and has been teaching at a graduate level for 15 years. His research focus lies on computational fluid dynamics (CFD).
Book Synopsis Lipid Oxidation by : Edwin N. Frankel
Download or read book Lipid Oxidation written by Edwin N. Frankel and published by Elsevier. This book was released on 2014-01-23 with total page 487 pages. Available in PDF, EPUB and Kindle. Book excerpt: In this second edition, Edwin Frankel has updated and extended his now well-known book Lipid oxidation which has come to be regarded as the standard work on the subject since the publication of the first edition seven years previously. His main objective is to develop the background necessary for a better understanding of what factors should be considered, and what methods and lipid systems should be employed, to achieve suitable evaluation and control of lipid oxidation in complex foods and biological systems. The oxidation of unsaturated fatty acids is one of the most fundamental reactions in lipid chemistry. When unsaturated lipids are exposed to air, the complex, volatile oxidation compounds that are formed cause rancidity. This decreases the quality of foods that contain natural lipid components as well as foods in which oils are used as ingredients. Furthermore, products of lipid oxidation have been implicated in many vital biological reactions, and evidence has accumulated to show that free radicals and reactive oxygen species participate in tissue injuries and in degenerative disease. Although there have been many significant advances in this challenging field, many important problems remain unsolved. This second edition of Lipid oxidation follows the example of the first edition in offering a summary of the many unsolved problems that need further research. The need to understand lipid oxidation is greater than ever with the increased interest in long-chain polyunsaturated fatty acids, the reformulation of oils to avoid hydrogenation and trans fatty acids, and the enormous attention given to natural phenolic antioxidants, including flavonoids and other phytochemicals.
