Summary

Modern Well Design - Second Edition presents a unified approach to the well design process. The objective is to provide a comprehensive overview of the well design process and drilling operations. Following the introduction, the second chapter addresses drilling fluids. Optimal mud weight, hole cleaning, hydraulic optimization and methods to handle circulation losses are covered here. A relative large chapter on geomechanics follows presenting methods for wellbore fracture and collapse modeling, including methods to interpret caliper logs. This second edition also contains a new generalized fracture model suitable for deep-water drilling. The start of any well design is to collect data and establish the design premises. Chapter four presents well integrity issues, methods to select depths of casing seats, and also some important completion and production requirements. The objective is to plan the well for its entire life, also defining loads that it may be subjected to at later stages. Chapters 5 and 6 describe actual well design in the North Sea and a sub-sea high pressure high temperature (HPHT) well. Chapter seven also addresses issues related to well integrity, and presents statistics of failures in production and injection wells. The book is intended to serve as curriculum in well design courses at undergraduate and graduate level. It is also aimed at personnel performing work related to petroleum wells, i.e. drilling engineers, production engineers, drilling supervisors, exploration geologists and others.
