Hydraulic Fracturing in Unconventional Reservoirs: Theories, Operations, and Economic Analysis, Second Edition, presents the latest operations and applications in all facets of fracturing. Enhanced to include today's newest technologies, such as machine learning and the monitoring of field performance using pressure and rate transient analysis, this reference gives engineers the full spectrum of information needed to run unconventional field developments. Covering key aspects, including fracture clean-up, expanded material on refracturing, and a discussion on economic analysis in unconventional reservoirs, this book keeps today's petroleum engineers updated on the critical aspects of unconventional activity. - Helps readers understand drilling and production technology and operations in shale gas through real-field examples - Covers various topics on fractured wells and the exploitation of unconventional hydrocarbons in one complete reference - Presents the latest operations and applications in all facets of fracturing

This book provides an overview on current sustainable machining. Its chapters cover the concept in economic, social and environmental dimensions. It provides the reader with proper ways to handle several pollutants produced during the machining process. The book is useful on both undergraduate and postgraduate levels and it is of interest to all those working with manufacturing and machining technology.

Lists citations with abstracts for aerospace related reports obtained from world wide sources and announces documents that have recently been entered into the NASA Scientific and Technical Information Database.

A. AHNELL and H. O'LEARY 1.1 Environmental technology Perhaps the place to start this book is with definitions of the two key words [1]: • Technology - the scientific study and practical application of the industrial arts, applied sciences, etc., or the method for handling a specific technical problem. • Environmental - all the conditions, circumstances and influences surrounding and affecting the development of an organism or group of organisms. Environmental technology is the scientific study or the application of methods to understand and handle problems which influence our surround ings and, in the case of this book, the surroundings around oil industry facilities and where oil products are used. Traditionally the phrase has meant the application of additional treatment processes added on to industrial processes to treat air, water and waste before discharge to the environment. Increasingly the phrase has a new meaning where the concept is to create cleaner process technology and move towards sustainabili ty. 1.2 The beginning As we begin our discussion of environmental technology, it is important to take a few moments to remember how we became so involved with this substance, oil. Regardless of our opinions about its use, oil is, and has been, the key resource in the twentieth century. From humble beginnings as a medicine and a lamp oil, oil has become the energy of choice for transport and many other applications and the feedstock for a major class of the material used today, plastic.
