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

The book explores the theoretical background of one of the most widespread activities in hydrocarbon wells, that of hydraulic fracturing. A comprehensive treatment of the basic phenomena includes: linear elasticity, stresses, fracture geometry and rheology. The diverse concepts of mechanics are integrated into a coherent description of hydraulic fracture propagation. The chapters in the book are cross-referenced throughout and the connections between the various phenomena are emphasized. The book offers readers a unique approach to the subject with the use of many numerical examples.

Hydraulic fracturing has been and continues to be a major techno logical tool in oil and gas recovery, nuclear and other waste disposal, mining and particularly in-situ coal gasification, and, more recently, in geothermal heat recovery, particularly extracting heat from hot dry rock masses. The understanding of the fracture process under the ac tion of pressurized fluid at various temperatures is of fundamental scientific importance, which requires an adequate description of thermomechanical properties of subsurface rock, fluid-solid interaction effects, as well as degradation of the host rock due to temperature gradients introduced by heat extraction. Considerable progress has been made over the past several years in laboratory experiments, analytical and numerical modeling, and in-situ field studies in various aspects of hydraulic fracturing and geothermal energy extraction, by researchers in the United States and Japan and also elsewhere. However, the results have been scattered throughout the literature. Therefore, the time seemed ripe for bringing together selected researchers from the two countries, as well as observers from other countries, in order to survey the state of the art, exchange scientific information, and establish closer collaboration for further, better coordinated scientific effort in this important area of research and exploration.

Hydraulic Fracturing effectively busts the myths associated with hydraulic fracturing. It explains how to properly engineer and optimize a hydraulically fractured well by selecting the right materials, evaluating the economic benefits of the project, and ensuring the safety and success of the people, environment, and equipment. From data estimation to design, operation, and performance management, the text presents a logical, step-by-step process for hydraulic fracturing that aids in proper engineering decision making when stimulating a particular reservoir. Numerous problem sets reinforce the learning and aid in risk assessment. Additional material is available from the CRC Press website.

Presents a systematic and comprehensive study of hydraulicfracturing, original in its concentration of core soilproblems There have been a number of well-studied cases in which damshave failed or been damaged by concentrated leaks for no apparentcause. In some of these experiences, investigators concluded thatdifferential settlement cracks were the probable causes, eventhough no cracks were seen on the surface. In these examples, itwas not determined whether the crack was open before the reservoirfilled or whether it might have opened afterward. In severalunsolved problems on the safety of the earth-rock fill dam, theproblem of hydraulic fracture in the soil core of the earth-rockfill dam is one that is widely paid attention by designers andresearchers. Hydraulic fracturing is generally considered as a keycause which may induce the leakage of the dam during firstfilling. In this extensive book, a new numerical simulate method issuggested. The method is based on the conventional two-dimensionalfinite element technique, and the theoretical formulations tocalculate energy release rate using virtual crack extension method.The influence factors on convergence of calculated J integral areinvestigated. The accuracy of the calculated J integral is verifiedby analysing the three typical problems in Fracture Mechanics, inwhich propagation of crack may follow mode I, mode II and mixedmode I-II respectively. Using the new numerical method, the factorsaffecting the occurrence of hydraulic fracturing in the earth-rockfill dam are investigated. The investigating results indicate thatincreasing any of the Young’s modulus, the Poisson’sratio and the density of the core soil is helpful to reduce thelikelihood of the occurrence of hydraulic fracturing. Thelikelihood of the occurrence of hydraulic fracturing increases withincreasing the water level or the crack depth. The lower part ofthe dam core is the zone in which the phenomenon of hydraulicfracturing may be induced easily. As an example to analyse theability of earth-rock fill dam to resist hydraulic fracturing, theNuozhadu Dam located in Western China is analysed. Presents a systematic and comprehensive study of hydraulicfracturing, original in its concentration of core soilproblems Focuses on the problem of hydraulic fracturing in earth-rockfill dams from three aspects; conditions and mechanisms ofhydraulic fracturing, criterion of hydraulic fracturing, andnumerical method on hydraulic fracturing Examines advanced laboratory soil testing, application ofnumerical methods and field testing/monitoring, all needed for abetter understanding of hydraulic fracturing in earth/rock filldams Provides an essential reference in an area of scarce researchin this field, and the need in high earth dam construction indeveloping countries is pressing Ideal for researchers in Hydraulic and Geotechnical EngineeringFields; Students on Masters or PhD courses; as well as Designersand Constructors in Hydraulic and Geotechnical EngineeringFields.
