Publisher: SigmaQuadrant ISBN 9780990683667, Full Color, HardBound

The primary aim of this instructional book is to expound upon the methodologies and engineering applications pertinent to the construction of geothermal wells. The exposition herein furnishes a comprehensive overview of subjects germane to geothermal drilling, while deliberately eschewing coverage of fundamental topics germane to conventional drilling operations, suggesting that interested readers peruse relevant texts in that regard.

Within the confines of this volume, emphasis is laid upon fundamental design considerations. The overarching objectives of this treatise are threefold: firstly, to instill a foundational comprehension of well design principles; secondly, to proffer guidance on anticipated operational challenges; and thirdly, to impart a lucid comprehension of thermal-related intricacies inherent to well design. Instances elucidating these principles are judiciously incorporated where deemed apropos. Notably, an unwavering engineering standpoint is maintained throughout the discourse on well engineering facets.

The book herein is tailored to a readership comprising practicing engineers, scientists, and designers, venture capitalists, litigation attorneys, and for expert witnesses, thereby aligning its treatment of the subject matter with the exigencies of these professional domains.
