Book excerpt: This thesis investigates the mechanism of pneumatic fracturing in geologic materials such as soil and rock. Pneumatic fracturing is a recently developed technique for increasing the permeability of geologic formations by the controlled injection of high pressure air. Present applications are focusing on the in situ remediation of contaminated soil and ground water, although pneumatic fracturing has other geotechnical uses such as pumping well enhancement. A comprehensive literature review of a related technology known as hydraulic fracturing is presented, which serves as background for development of a pneumatic fracturing model. Pressure-time histories from actual pneumatic injections are analyzed in detail to understand the failure mechanism. Several distinct stages of a typical fracture event are identified including: fracture initiation, fracture extension, fracture maintenance, and fracture residual. Reinjection behavior of previously fractured formations is also investigated. The entire fracture event was consistently found to be quite rapid, lasting only several seconds, leading to the conclusion that the formations will respond brittlely. Based on these pressure-time analyses, an original analytical model is developed for the prediction of fracture initiation pressure and fracture maintenance pressure. The model describes the stress conditions leading to failure in and around a discrete section of borehole during pneumatic injection. The model has a linear form, and assumes the geologic medium is brittle-elastic, uniformly stratified, overconsolidated, horizontally isotropic, and semi-porous. The two dominant terms found to influence fracture pressure are overburden stress and apparent tensile strength of the formation. The effects of pieozometric head are also incorporated, so that the model is applicable to both the vadose zone and saturated zone. Validation of the model is made with actual field data from several different research test sites. The trends of the data show reasonable agreement with the model, and numerical coefficients are determined by regression. Tentative relationships were developed for two types of geologic media: clayey silt and siltstone/sandstone. Overburden gradients for the clayey silt, siltstone and sandstone ranged from 1.0 to 2.5 psi per foot of depth. Apparent cohesive/tensile strengths for these materials ranged from 5 to 23 psi, 41 to 130 psi and 42 to 52 psi respectively. Sample computations with the model are presented, and the thesis concludes with recommendations for future study.

Available in PDF, EPUB and Kindle. Book excerpt: There is a strong need for innovation and the development of viable renewable energy sources. Recent technological advances now allow natural gas supplies—previously believed inaccessible or nonexistent—to be discovered, mined, and processed for both industrial and consumer use. The technology, a controversial process that is alternatively called hydraulic fracturing, fracking, fracing, or hydrofracking, has greatly expanded natural gas production in the United States. Presenting a balanced discussion, Environmental Impacts of Hydraulic Fracturing is a comprehensive guide to all aspects of hydraulic fracturing used to extract natural gas, along with gas exploration and production in various shale fields. As the use of hydraulic fracturing has grown, concerns about its environmental and public health impacts have also increased—one of the most significant concerns being the fluids that are injected into rock formations to cause the fracturing contain potentially hazardous chemical additives. The book covers all facets of the issue, including ongoing controversies about the environmental and operator safety issues arising from possible water pollution, drinking water contamination, on-the-job safety hazards, and harmful chemical exposure to workers and residents near well areas. The author discusses both the pros and cons of hydraulic fracturing, explaining the process in great detail. He describes the benefits of hydraulic fracturing and its importance in making the United States energy independent by drilling for its own resources, as well as the potential impacts to the surrounding environment. The text also includes suggestions and recommendations on how to mitigate environmental damage. Arguably the first book of its kind, this is the go-to text on the use and impacts of hydraulic fracturing.

Available in PDF, EPUB and Kindle. Book excerpt: Revised to include current components considered for today’s unconventional and multi-fracture grids, Mechanics of Hydraulic Fracturing, Second Edition explains one of the most important features for fracture design — the ability to predict the geometry and characteristics of the hydraulically induced fracture. With two-thirds of the world’s oil and natural gas reserves committed to unconventional resources, hydraulic fracturing is the best proven well stimulation method to extract these resources from their more remote and complex reservoirs. However, few hydraulic fracture models can properly simulate more complex fractures. Engineers and well designers must understand the underlying mechanics of how fractures are modeled in order to correctly predict and forecast a more advanced fracture network. Updated to accommodate today’s fracturing jobs, Mechanics of Hydraulic Fracturing, Second Edition enables the engineer to: Understand complex fracture networks to maximize completion strategies Recognize and compute stress shadow, which can drastically affect fracture network patterns Optimize completions by properly modeling and more accurately predicting for today’s hydraulic fracturing completions Discusses the underlying mechanics of creating a fracture from the wellbore Enhanced to include newer modeling components such as stress shadow and interaction of hydraulic fracture with a natural fracture, which aids in more complex fracture networks Updated experimental studies that apply to today’s unconventional fracturing cases

Available in PDF, EPUB and Kindle. Book excerpt: Hydraulic fracturing, commonly referred to as“fracking,” is a technique used by the oil and gasindustry to mine hydrocarbons trapped deep beneath theEarth’s surface. The principles underlying the technology arenot new. Fracking was first applied at the commercial level in theUnited States as early as 1947, and over the decades it has beenapplied in various countries including Canada, the UK, and Russia.The author worked with engineering teams as early as the mid-1970sin evaluating ways to improve oil recovery from this practice. By and large fracking was not an economically competitiveprocess and had limited applications until the early 2000s. Several factors altered the importance of this technology, amongthem being significant technological innovations in drillingpractices with impressive high tech tools for exploration, wellconstruction and integrity, and recovery along with discoveries ofmassive natural gas reserves in the United States and other partsof the world. These factors have catapulted the application of thetechnology to what is best described as the gold rush of the 21stcentury, with exploration and natural gas plays proceeding at apace that seemingly is unrivaled by any historical industrialendeavor. But this level of activity has invoked widespreadcriticism from concerned citizens and environmental groups inalmost every nation across the Globe. This outstanding new volume offers the industry a handbook ofenvironmental management practices that can mitigate risks to theenvironment and, through best practices and current technologies,to conform to the current standards and regulations that are inplace to provide the world with the energy it needs while avoidingenvironmental damage. For the new hire, veteran engineer, andstudent alike, this is a one-of-a-kind volume, a must-have foranyone working in hydraulic fracturing.

This book was released on 2018-12-17 with total page 208 pages. Available in PDF, EPUB and Kindle. Book excerpt: Hydraulic fracturing is essential technology for the development of unconventional resources such as tight gas. So far, there are no numerical tools which can optimize the whole process from geological modeling, hydraulic fracturing until production simulation with the same 3D model with consideration of the thermo-hydro-mechanical coupling. In this dissertation, a workflow and a numerical tool chain were developed for design and optimization of multistage hydraulic fracturing in horizontal well regarding a maximum productivity of the tight gas wellbore. After the verification a full 3D reservoir model is generated based on a real tight gas field in the North German Basin. Through analysis of simulation results, a new calculation formula of FCD was proposed, which takes the proppant position and concentration into account and can predict the gas production rate more accurately. However, not only FCD but also proppant distribution and hydraulic connection of stimulated fractures to the well, geological structure and the interaction between fractures are determinant for the gas production volume. Through analysis the numerical results of sensitivity analysis and optimization variations, there is no unique criterion to determine the optimal number and spacing of the fractures, it should be analyzed firstly in detail to the actual situation and decided then from case to case.

This book was released on 1995 with total page 248 pages. Available in PDF, EPUB and Kindle. Book excerpt: This thesis investigates conceptual integration of the Pneumatic Fracturing (PF) process with In Situ Vitrification (ISV) for remediation of contaminated soil. Integration will permit ISV melts to be initiated below the ground surface and extend the depth of the ISV process. Bench scale experiments were conducted in 4.9 ft3 (0.14 m3) Plexiglas tanks filled with a test soil that was specifically blended to simulate the Hanford Formation in Richland, WA. Discrete pneumatic fractures were successfully created and filled with the ISV starter path material. Conductivity measurements made across two graphite electrodes exhibited a pre-fracture soil resistance of 427 ohms, which was reduced to an average of 0.80 ohms after fracture injection. A model was developed to predict transport distance of the ISV starter path media in pneumatically induced fractures. The model estimates fracture propagation distance using a finitedifference approach, as well as the critical fluid velocity necessary to keep the starter path media suspended, Model calculations show the effective radius of the integrated process should range up to several meters in the Hanford Formation. The thesis concludes with operational recommendations for full scale application.

This book was released on 2017-03-27 with total page 192 pages. Available in PDF, EPUB and Kindle. Book excerpt: The expansion of unconventional petroleum resources in the recent decade and the rapid development of computational technology have provided the opportunity to develop and apply 3D numerical modeling technology to simulate the hydraulic fracturing of shale and tight sand formations. This book presents 3D numerical modeling technologies for hydraulic fracturing developed in recent years, and introduces solutions to various 3D geomechanical problems related to hydraulic fracturing. In the solution processes of the case studies included in the book, fully coupled multi-physics modeling has been adopted, along with innovative computational techniques, such as submodeling. In practice, hydraulic fracturing is an essential project component in shale gas/oil development and tight sand oil, and provides an essential measure in the process of drilling cuttings reinjection (CRI). It is also an essential measure for widened mud weight window (MWW) when drilling through naturally fractured formations; the process of hydraulic plugging is a typical application of hydraulic fracturing. 3D modeling and numerical analysis of hydraulic fracturing is essential for the successful development of tight oil/gas formations: it provides accurate solutions for optimized stage intervals in a multistage fracking job. It also provides optimized well-spacing for the design of zipper-frac wells. Numerical estimation of casing integrity under stimulation injection in the hydraulic fracturing process is one of major concerns in the successful development of unconventional resources. This topic is also investigated numerically in this book. Numerical solutions to several other typical geomechanics problems related to hydraulic fracturing, such as fluid migration caused by fault reactivation and seismic activities, are also presented. This book can be used as a reference textbook to petroleum, geotechnical and geothermal engineers, to senior undergraduate, graduate and postgraduate students, and to geologists, hydrogeologists, geophysicists and applied mathematicians working in this field. This book is also a synthetic compendium of both the fundamentals and some of the most advanced aspects of hydraulic fracturing technology.
