Download or read book An Experimental Study of Foam Rheology and Its Impact on Foam Performance in the Fractured System written by Ying Yu and published by . This book was released on 2020 with total page 126 pages. Available in PDF, EPUB and Kindle. Book excerpt: Foam has been gaining increasing attention from the gas and oil industries for its mobility control ability, especially for the fractured system. However, its performance is negatively affected by its instability at elevated temperature and pressure. In this research, a comprehensive investigation of nitrogen foam morphology and bulk and in-situ foam rheology has been performed, utilizing the microscope, rheometer, and core-flooding system to explore the effect of chemicals and foam generation methods. We found a direct correlation between the shear and in-situ rheology of foam that allows the prediction of apparent in-situ viscosity based on bulk foam rheology. Then, we focused on scCO2 foam made with a recent category of chemicals, viscoelastic surfactants (VES). The scCO2 foam performance in reservoir conditions has been tested with the PVT cell and core-flooding system. We found a strong correlation between the viscosity/viscoelasticity of the VES systems and their performance as foam stabilizers in both bulk form and porous media. To the best of our knowledge, these results unveil, for the first time, the impact of surfactant viscosity/viscoelasticity on supercritical CO2 foam performance in bulk and porous media in a systematic manner. Finally, we applied the above knowledge of the foam to the fractured Berea sandstone system. We noticed the significant foam mobility control ability in the fractured system, and we concluded the effect of fracture surface roughness on foam flow performance in the presence and absence of oil.

Download or read book The Physics of Foams written by D. L. Weaire and published by Oxford University Press. This book was released on 1999 with total page 268 pages. Available in PDF, EPUB and Kindle. Book excerpt: Ordinary foams such as the head of a glass of beer and more exotic ones such as solid metallic foams raise many questions for the physicist and have attracted a substantial research community in recent years. The present book describes the results of extensive experiments, computer simulations, and theories in an authoritative yet informal style, making ample use of illustrations and photographs. As an introduction to the whole field of the physics of foams it puts a strong emphasis on liquids while also including solid foams. Simple, idealized models are adopted and their consequences explored. Specific topics include: structure, drainage, rheology, conductivity, and coarsening. A minimum of mathematics is used. Theory and experiment are described together at every stage. A guide to further reading is provided through carefully selected references. This is a complete and coherent introduction to the subject which no other modern text currently offers.
Download or read book Rheology of Cross linked Polymers and Polymer Foams written by John Herman and published by . This book was released on 2015 with total page 102 pages. Available in PDF, EPUB and Kindle. Book excerpt: Typical polymers have a time-dependent response to loading which results in stress relaxation or creep. Models using springs/dashpots or Volterra integrals are capable of predicting the material response, but place little or no emphasis on the reasoning behind the response. This research proposes a microscopic reasoning behind polymer chain movement, while developing a model to predict the creep and stress relaxation of a polymer foam. Based on the theorized slip/stick of polymer chains as they slide past each other, this model successfully predicts the behavior of a PMI polymer foam under tensile loads. This model lends insights into polymer microscopic behavior, which may be used for the development of future polymer materials. When possible, industry standard test methods are used to obtain tensile creep and stress relaxation results from rectangular specimens of Rohacell 31 IG foam. A common set of material parameters is fitted to the data, validating the micromechanic reasoning to polymer chain movement. To gain insight into observed test result variability, an investigation of the elastic modulus and material density relationship is performed using nominal foam densities of 31 kg/m℗đ, 51 kg/m℗đ, 71 kg/m℗đ. Additional testing and modeling is performed to validate the model under load/partial-unload/hold, load/unload/recovery, and load/instantaneous-unload test cycles. The model successfully captures the observed material nuances during these more complex loading cycles.
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.

Book excerpt: Foams are ubiquitous in our daily lives. Their presence is highly desirable in certain foods, drinks and cosmetics, and they are essential in oil recovery and mineral extraction. In some industrial processes (such as the manufacture of glass, paper and wine) foams are an unwelcome by-product. Why do they appear? What controls the rate at which they disappear? Do they flow in the same way as ordinary liquids? All of these questions and more are addressed here, incorporating significant recent contributions to the field of foams. This book is the first to provide a thorough description of all aspects of the physico-chemical properties of foams. It sets out what is known about their structure, their stability, and their rheology. Engineers, researchers and students will find descriptions of all the key concepts, illustrated by numerous applications, as well as experiments and exercises for the reader. A solutions manual for lecturers is available via the publisher's web site.
Download or read book Exploitation of Unconventional Oil and Gas Resources written by Kenneth Imo-Imo Israel Eshiet and published by . This book was released on 2019-07-10 with total page 152 pages. Available in PDF, EPUB and Kindle. Book excerpt: The stimulation of unconventional hydrocarbon reservoirs is proven to improve their productivity to an extent that has rendered them economically viable. Generally, the stimulation design is a complex process dependent on intertwining factors such as the history of the formation, rock and reservoir fluid type, lithology and structural layout of the formation, cost, time, etc. A holistic grasp of these can be daunting, especially for people without sufficient experience and/or expertise in the exploitation of unconventional hydrocarbon reserves. This book presents the key facets integral to producing unconventional resources, and how the different components, if pieced together, can be used to create an integrated stimulation design. Areas covered are as follows: • stimulation methods, • fracturing fluids, • mixing and behavior of reservoir fluids, • assessment of reservoir performance, • integration of surface drilling data, • estimation of geomechanical properties and hydrocarbon saturation, and • health and safety. Exploitation of Unconventional Oil and Gas Resources: Hydraulic Fracturing and Other Recovery and Assessment Techniques is an excellent introduction to the subject area of unconventional oil and gas reservoirs, but it also complements existing information in the same discipline. It is an essential text for higher education students and professionals in academia, research, and the industry.

This book was released on 2012 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: This research effort is focused on understanding the mechanical response of foams, and other complex fluids, from the microscopic to the macroscopic level. The research uses a model two-dimensional system: bubble rafts. Bubble rafts are a single layer of gas bubbles with liquid walls that float on a water surface. The work involves studies of the macroscopic response of foam under various conditions of external forcing, mesoscopic studies of bubble motion, and systematic variations of the microscopic details of the system. In addition to characterizing the specific properties of the bubble raft, a second aim of the research is to provide experimental tests of various general theories that have recently been developed to characterize complex fluids. Primarily, the focus is on testing the proposed jamming phase diagram paradigm. This paradigm suggests that a general jamme state of matter exists and is common to a wide range of systems, including foam, colloids, granular matter, glasses, and emulsions. Therefore, we have extended our research in two directions. First, we have included studies of plastic bead rafts. These are systems of plastic beads floating on the air-water interface. The advantage of plastic beads is that they do not pop, so they can be studied for the much longer periods of time required to measure the slow dynamics associated with the jammed state. Also, they allow us to explore a different density regime than the bubbles. Second, to better understand the role of defects in jamming behavior, we have done a few experiments on the impact of defects on domain growth.
