First published in 1991. This volume presents a brief description of the natural conditions of the permafrost regions, the properties of the permafrost and the processes occurring in it, the fundamentals of the heat transfer processes during drilling and the service temperature conditions of the tool. Methods and devices for cooling the flushing media, principles of quality control of flushing agents and the technology and commercial viability of their use during drilling in the permafrost have been considered. The main emphasis in this book is on the drilling technology which uses a variety of flushing agents. The text also includes a description of the technology of utilizing grouting solutions, the theory and practice of drilling with simultaneous freezing of weakly cohesive, moist ground as well as jdrilling holes in the ice-sheets of the circumpolar regions. This book is intended for engineers and technical personnel engaged in drilling for exploratory geological works.
A 1949 drill site in the Naval Petroleum Reserve Number 4, Alaska, the Fish Creek Test Well 1, was examined in August 1977 to determine the disturbance caused by drilling activities and to analyze the response and recover of the vegetation, soils, permafrost, and surficial materials to that distrubance. The site, abandoned in 1949, is located along Camp Creek, a tributary to Fish Creek located 28 km. south of Atigaru Point and west of Nuiqsut.
These proceedings contain two hundred and eighteen papers representing the work of authors from countries across the world. They cover a wide range of research and applications in safety and reliability issues that concern all types of systems, processes and structures.
This book provides a review of mechanical ice drilling technology, including the design, parameters, and performance of various tools and drills for making holes in snow, firn and ice. The material presents the historical development of ice drilling tools and devices from the first experience taken place more than 170 years ago to the present day and focuses on the modern vision of ice drilling technology. It is illustrated with numerous pictures, many of them published for the first time. This book is intended for specialists in ice core sciences, drilling engineers, glaciologists, and can be useful for high-school students and other readers who are very interested in engineering and cold regions technology.
