Of all the technologies employed by hydrologists, environmental engineers, and scientists interested in subsurface conditions, drilling is one of the most frequently used but most poorly understood. This venerable industry-tested manual, developed by one of the world’s leading authorities on drilling technology is one the most comprehensive and practical books on drilling and drill-logging in the world. Written, illustrated, and peer-reviewed by some of the world’s leading experts, it is heavily illustrated with clear diagrams and charts for maximum clarity. Emphasizing basics, the book also offers advanced techniques for environmentally non-destructive drilling methods.
