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.
Book Synopsis Linking Adjusted Brine Chemistry EOR Effects to Interfacial Rheology and Solid Liquid Interfacial Reactions by : Mohamed Ibrahim Hafez Mohamed
Download or read book Linking Adjusted Brine Chemistry EOR Effects to Interfacial Rheology and Solid Liquid Interfacial Reactions written by Mohamed Ibrahim Hafez Mohamed and published by . This book was released on 2017 with total page 91 pages. Available in PDF, EPUB and Kindle. Book excerpt: In this work, we aim at linking brine-crude oil interactions, and rock-fluid interactions in oil reservoirs. It is often claimed that either interactions is the dominant factor causing increased oil recovery while adjusting the brine chemistry and adjusting the salinity of the injected brine. Using contact angle measurements, zeta potential, and spontaneous imbibition the rock-fluid properties were evaluated. Low-salinity brine was found to alter the wettability of strong oil-wet sandstone surfaces to intermediate oil wet. Oil wetted quartz substrates showed no response when the exposed to low-salinity brine. Modifying the brine chemistry using sulfate ions and calcium ions result in a slight reduction of the contact angle without altering the wettability. Measurement of interfacial rheology using pendant drop, drop size distribution and spinning drop showed that brine could govern less snap-off and more coalescence of oil droplets to form oil banks. Interfacial findings presented a more satisfactory explanation of the recovery trends observed.
Book Synopsis Influence of Anion Type on the Dynamic Interfacial Properties of a Crude Oil by : Jordy Sarmas
Download or read book Influence of Anion Type on the Dynamic Interfacial Properties of a Crude Oil written by Jordy Sarmas and published by . This book was released on 2022 with total page 48 pages. 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.

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 Foam and Foam Films written by D. Exerowa and published by Elsevier. This book was released on 1997-12-11 with total page 797 pages. Available in PDF, EPUB and Kindle. Book excerpt: The main physicochemical aspects of foam and foam films such as preparation, structure, properties, are considered, giving a special emphasis on foam stability. It is shown that the foam and foam films are an efficient object in the study of various surface phenomena and in establishing regularities common for different interfaces, in particular, water/oil interface. The techniques and results on foam films have an independent meaning and involve the latest achievement in this field, with a focus on authors' results. The book has an expressed monographic character. It reveals joint ideas, i.e. the quantitative approach in treating foams is based on foam film behaviour and the techniques for controlling the foam liquid content, developed by the authors. A major contribution represents the independent consideration of formation and stability of foam films in theoretical and experimental aspects. No monograph published so far reveals these topics in the mentioned manner. Data and information about foams, physicochemical characterization of surfactants, phospholipids and polymers can also be found. Furthermore, the book provides information about: techniques involved in the study of foam films and foam structure and properties; foam drainage; processes of destruction in gravitational and centrifugal fields; reasons for stability of films and their role in the processes running in the foam; mechanical, rheological, optical, thermophysical, electrical properties; foam destruction upon addition of antifoams (mechanism of destruction, techniques, application); scientific principles of controlling foam properties and their application in foam separation and concentration; enhanced oil recovery; thermodynamic and non-equilibrium properties of foam films, stabilized by surfactants, phospholipids and polymers; techniques for the study of surface forces; formation and stability of foam films; black films, including bilayers; new theories of stability of amphiphile bilayer; experiments involved in this stability; application in biology and medicine.
