Multilateral Wells is intended to illuminate the most important aspects of multilateral wells in a concise way and serve as a valuable resource for engineers and geoscientists desiring an introduction to complex well architectures. This book is comprehensive enough to give readers practical tools they can apply in the design and analysis of multilateral wells, while also pointing to the appropriate literature for more advanced studies. This volume should appeal to a broad audience in petroleum engineering and the geosciences; it has been designed for use by undergraduate students, graduate students, current practitioners, educators, and researchers.
