Book Synopsis Percutaneous Vertebroplasty and Kyphoplasty by : John M. Mathis
Download or read book Percutaneous Vertebroplasty and Kyphoplasty written by John M. Mathis and published by Springer Science & Business Media. This book was released on 2006-11-22 with total page 316 pages. Available in PDF, EPUB and Kindle. Book excerpt: Since the ?rst edition of this book was published in 2002, there have been many advances in our knowledge of percutaneous vertoplasty (PV), particularly about how to perform the procedure more safely and how to approach more complex case situations. Additionally, mate- als that were initially used “off label” or that simply were not FDA approved have completed their governmental review and have received FDA approval. This has increased the legitimacy of the p- cedure from the legal and reimbursement perspective. Controversy over height restoration and device selection has become a progressively bigger issue over time. Kyphoplasty (balloon assisted vertebroplasty) has received tremendous emphasis. This book c- pares and contrasts data and claims that differentiate kyphoplasty from percutaneous vertebroplasty. We also look at other methods that pot- tially can be used for height restoration. New procedures that deal with bone augmentation in other anatomic regions have evolved (i.e., sacroplasty) and are discussed. As this re- lution in image-guided percutaneous bone augmentation has dev- oped, multiple medical specialties have embraced these procedures in their training programs for both residents and practicing physicians.

Book Synopsis Glucocorticoid-induced Osteoporosis by : Andrea Giustina
Download or read book Glucocorticoid-induced Osteoporosis written by Andrea Giustina and published by Karger Medical and Scientific Publishers. This book was released on 2002 with total page 213 pages. Available in PDF, EPUB and Kindle. Book excerpt: Osteoporosis is one of the most clinically relevant disabling chronic disease encountered in clinical practice. A common cause of osteoporosis is glucocorticoid excess, as glucocorticoids may increase bone resorption, inhibit bone formation, have indirect actions on bone by decreasing intestinal calcium absorption and induce hypercalciuria. This book presents a comprehensive overview of the effects of glucocorticoids on bone metabolism and structure and on the diagnosis and treatment of glucocorticoid-induced osteoporosis. It aims at providing updated information on the pathogenesis, diagnosis and treatment of this often dramatic complication of glucocorticoid excess. Being one of the few publications completely devoted to glucocorticoid-induced osteoporosis it will heighten the awareness of specialists who prescribe glucocorticoids of the clinical relevance of this treatment complication. 'Glucocorticoid-Induced Osteoporosis' is addressed to clinical experts as well as to general practitioners who will both benefit from the comprehensive and integrative view of the management of patients exposed to glucocorticoids.
Book Synopsis Anabolic Treatments for Osteoporosis by : James F. Whitfield
Download or read book Anabolic Treatments for Osteoporosis written by James F. Whitfield and published by CRC Press. This book was released on 1997-10-20 with total page 298 pages. Available in PDF, EPUB and Kindle. Book excerpt: Osteoporosis, a growing epidemic among women in North America, Europe, and Japan, is a painful, costly disease that has presented a treatment challenge to healthcare professionals. Until recently, therapies have focused on agents that slow bone resorption, and have had only limited success at increasing bone mass. However, exciting new developments are on the verge of changing the treatment of this debilitating disorder. Two anabolic agents, the parathyroid hormone (PTH) and the fluoride ion, show tremendous promise as tools for building and retaining bone - with no adverse side effects. Anabolic Treatments for Osteoporosis is a comprehensive account of the latest studies that have been carried out on these two agents, and a thorough assessment of their prospects as osteoporosis therapeutics. This unique book combines basic science and up-to-date clinical data to present a complete picture of this breakthrough in the treatment of a globally significant health issue.
Book Synopsis Laboratory Studies of Injection Into Horizonal Fractures by :
Download or read book Laboratory Studies of Injection Into Horizonal Fractures written by and published by . This book was released on 1996 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Most geothermal reservoirs are extensively fractured and injected fluids usually enter the reservoir formation at distinct feed points. As the cold water passes through the hot rock, it is heated, and may be recovered at production wells for power production. The influence of fractures is two-fold. Firstly, preferential pathways exist along major faults and the general motion of fluids away from injection wells is controlled by the effective permeability structure. Secondly, since fractures can be spaced several metres or more apart and the flow rates within each fracture can be relatively high, the injected fluid does not necessarily attain thermal equilibrium will all of the host rock at a given distance from the injection well. It is important that sufficient heat transfer between the fluid and rock occurs before the injected fluid is recovered at an injection well in order to prevent thermal breakthrough. In this paper we present preliminary results of an experimental research program examining the effects of injection into fractures. We build upon previous theoretical work by seeking to confirm the results and then discuss the initial results of injection into superheated reservoirs.
Book Synopsis Reservoir Geomechanics by : Mark D. Zoback
Download or read book Reservoir Geomechanics written by Mark D. Zoback and published by Cambridge University Press. This book was released on 2010-04-01 with total page 505 pages. Available in PDF, EPUB and Kindle. Book excerpt: This interdisciplinary book encompasses the fields of rock mechanics, structural geology and petroleum engineering to address a wide range of geomechanical problems that arise during the exploitation of oil and gas reservoirs. It considers key practical issues such as prediction of pore pressure, estimation of hydrocarbon column heights and fault seal potential, determination of optimally stable well trajectories, casing set points and mud weights, changes in reservoir performance during depletion, and production-induced faulting and subsidence. The book establishes the basic principles involved before introducing practical measurement and experimental techniques to improve recovery and reduce exploitation costs. It illustrates their successful application through case studies taken from oil and gas fields around the world. This book is a practical reference for geoscientists and engineers in the petroleum and geothermal industries, and for research scientists interested in stress measurements and their application to problems of faulting and fluid flow in the crust.

Book Synopsis CO2 Injection in the Network of Carbonate Fractures by : J. Carlos de Dios
Download or read book CO2 Injection in the Network of Carbonate Fractures written by J. Carlos de Dios and published by Springer Nature. This book was released on 2020-12-17 with total page 245 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book presents guidelines for the design, operation and monitoring of CO2 injection in fractured carbonates, with low permeability in the rock matrix, for geological storage in permanent trapping. CO2 migration is dominated by fractures in formations where the hydrodynamic and geochemical effects induced by the injection play a key role influencing the reservoir behavior. CO2 injection in these rocks shows specific characteristics that are different to injection in porous media, as the results from several research studies worldwide reveal. All aspects of a project of this type are discussed in this text, from the drilling to the injection, as well as support works like well logging, laboratory and field tests, modeling, and risk assessment. Examples are provided, lesson learned is detailed, and conclusions are drawn. This work is derived from the experience of international research teams and particularly from that gained during the design, construction and operation of Hontomín Technology Development Plant. Hontomín research pilot is currently the only active onshore injection site in the European Union, operated by Fundación Ciudad de la Energía-CIUDEN F.S.P. and recognized by the European Parliament as a key test facility. The authors provide guidelines and tools to enable readers to find solutions to their problems. The book covers activities relevant to a wide range of practitioners involved in reservoir exploration, modeling, site operation and monitoring. Fluid injection in fractured media shows specific features that are different than injection in porous media, influencing the reservoir behavior and defining conditions for safe and efficient operation. Therefore, this book is also useful to professionals working on oil & gas, hydrogeology and geothermal projects, and in general for those whose work is related to activities using fluid injection in the ground.
Book Synopsis Injection-induced Fractures and Polymer Injectivity in Unconsolidated Formations by : Zihao Li (Ph. D.)
Download or read book Injection-induced Fractures and Polymer Injectivity in Unconsolidated Formations written by Zihao Li (Ph. D.) and published by . This book was released on 2022 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Polymers are often used for enhanced oil recovery (EOR) and in-situ site remediation. Polymer injectivity is an essential indicator in the project economics. Reduced injectivity due to the high polymer viscosity can be one of the most important challenges in a field polymer flood project, more so than the cost of chemicals. Although injection of viscous polymer is expected to significantly reduce the injectivity, observations from field data of polymer floods often show higher than expected injectivity for viscoelastic HPAM polymers. One explanation for the unexpected injectivity is that the injection pressure may increase above the formation parting pressure (FPP) at which fractures are created from the wellbore. The effects of non-Newtonian rheology on fracture opening and fluid leakoff morphology is largely unexplored compared to Newtonian fluids. Comprehensive studies that explain the polymer-driven fracturing mechanisms are lacking, even in unconsolidated sands. In this study, we study polymer-driven fracture initiation through experiments and numerical simulations. First, we conduct experiments injecting Newtonian, shear-thinning and viscoelastic fluids into a sand-filled Hele-Shaw cell to study fluid invasion and fracturing patterns of sand and injected fluids. The experimental results demonstrate complex fracture patterns depending on injection velocity, fluid viscosity, boundary conditions and fluid rheology. We use digital image correlation to demonstrate that the fracturing mechanism in sand is associated with shear dilation at the tip of fracture and fracture offshoots. Compared to Newtonian fluids, shear-thinning fluids cause thinner fracture openings and more leakoff. Injecting viscoelastic fluid into sand creates a more irregular leakoff pattern, with fluid sometimes leaking mostly at the fracture tip for high injection rates. Second, we investigate the mechanisms behind polymer-driven fractures in cohesionless granular media by coupling the discrete element method (DEM) with computational fluid dynamics (CFD) at the pore/grain scale. Fluid injection can initiate a fracture orthogonal to the minimum principal stress, as expected, through viscous drag forces. However, the displacement field around the fracture is much more complex than what is expected for a linear elastic solid, showing that (1) fracture propagation requires small leak-off (a few times the fracture width) and (2) localized shear deformation ahead of the fracture tip affects fracture morphology. Finally, we simulate the injection of the polymer into the unconsolidated sand. Polymer injection can create fractures in the granular media along the direction perpendicular to the minimum principal stress, thereby reducing wellbore pressure buildup at a constant polymer injection rate. Polymer rheology, water quality, and undissolved polymer also affect the polymer injectivity. This work shows the initiation of polymer-driven fractures in a granular model and demonstrate its implications on polymer injectivity
Book Synopsis The Initiation, Propagation, and Arrest of Joints and Other Fractures by : John W. Cosgrove
Download or read book The Initiation, Propagation, and Arrest of Joints and Other Fractures written by John W. Cosgrove and published by Geological Society of London. This book was released on 2004 with total page 340 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume is a state of the art look at our understanding of joint development in the crust. Answers are provided for such questions as the mechanisms by which joints are initiated, the factors controlling the path they follow during the propagation process, and the processes responsible for the arrest of joints. Many of the answers to these questions can be inferred from the geometry of joint surface morphology and joint patterns. Joints are a record of the orientation of stress at the time of propagation and as such they are also useful records of ancient stress fields, regional and local. Because outcrop and subsurface views of joints are limited, statistical techniques are required to characterize joints and joint sets. Finally, joints are subject to post-propagation stresses that further localize deformation and are the focus for the development of new structures.

Book excerpt: Since the publication of the first edition, the U.S. Surgeon General released the first-ever report on bone health and osteoporosis in October 2004. This report focuses even more attention on the devastating impact osteoporosis has on millions of lives. According to the National Osteoporosis Foundation, 2 million American men have osteoporosis, and another 12 million are at risk for this disease. Yet despite the large number of men affected, the lack of awareness by doctors and their patients puts men at a higher risk that the condition may go undiagnosed and untreated. It is estimated that one-fifth to one-third of all hip fractures occur in men. This second edition brings on board John Bilezikian and Dirk Vanderschueren as editors with Eric Orwoll. The table of contents is more than doubling with 58 planned chapters. The format is larger – 8.5 x 11.

Book Synopsis Diagnosis of Induced Hydraulic Fractures During Polymer Injection by : Yiwei Ma (M.S.E.)
Download or read book Diagnosis of Induced Hydraulic Fractures During Polymer Injection written by Yiwei Ma (M.S.E.) and published by . This book was released on 2015 with total page 122 pages. Available in PDF, EPUB and Kindle. Book excerpt: Polymer transport with complex fluid rheology was implemented into an existing hydraulic fracturing simulator (CFRAC), and the implementation was extensively validated. Shear thinning viscosity was included for polymer fluid flow in both porous media and fractures. Shear thickening viscosity was implemented for flow in the matrix. Polymer injections were simulated to investigate the effect of polymer rheology, including both shear thinning and shear thickening behaviors, on polymer injectivity and on the possibility of induced hydraulic fracturing. The results indicated that shear thickening decreases injectivity and can induce initiation of hydraulic fractures. The hydraulic fractures substantially enhance injectivity, and eliminate the reduction in injectivity due to shear thickening. Pressure fall off tests were simulated to study the effect of polymer rheology on the identification of hydraulic fractures from the shut-in transient after shut-in. The results showed that standard methods from pressure transient analysis can be applied to diagnose the presence hydraulic fracturing by identifying a linear flow regime and fracture closure on a Bourdet derivative plot and a square root of time plot. It was found that these methods are effective regardless of shear thickening and shear thinning rheology. However, the results suggested that if the fracture is small and closes quickly, this could cause difficulty for the diagnosis.
