Geotechnical and Exploration Drilling in the Polar Regions by Pavel G. Talalay Pdf
This book provides a comprehensive review of drilling technologies in the polar regions, from the portable drilling equipment for shallow sampling and coring, to heavy drilling equipment for deep onshore and offshore drilling. Particular attention is given to safe drilling methods in permafrost. In recent years, interest in drilling in the polar regions has increased under the pressure of the geopolitical “rush” and the undiscovered resource potential. In addition, borehole monitoring of permafrost thermal states is urgently needed to obtain evidence of climate change. The book focuses on the latest drilling technologies but also discusses the historical development of sampling, and drilling tools and devices, over the last 60–70 years providing valuable insights into a way forward and future possibilities.
Thermal Ice Drilling Technology by Pavel G. Talalay Pdf
This book provides a review of thermal ice drilling technologies, including the design, parameters, and performance of various tools and drills for making holes in ice sheets, ice caps, mountain glaciers, ice shelves, and sea ice. In recent years, interest in thermal drilling technology has increased as a result of subglacial lake explorations and extraterrestrial investigations. The book focuses on the latest ice drilling technologies, but also discusses the historical development of ice drilling tools and devices over the last 100 years to offer valuable insights into what is possible and what not to do in the future. Featuring numerous figures and pictures, many of them published for the first time, it is intended for specialists working in ice-core sciences, polar oceanography, drilling engineers and glaciologists, and is also a useful reference for researchers and graduate students working in engineering and cold-regions technology.
Mechanical Ice Drilling Technology by Pavel G. Talalay Pdf
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.
Topics in this international symposium on mining in the arctic included arctic mining in Raglan; analysis and prediction of water infiltration in underground, frozen placer mines; red dog mine-operations update and design of paste tailings disposal in the Russian Sub-Arctic.
Natural Gas Hydrate - Arctic Ocean Deepwater Resource Potential by Michael D. Max,Arthur H. Johnson,William P. Dillon Pdf
The book is an up-to-date basic reference for natural gas hydrate (NGH) in the Arctic Ocean. Geographical, geological, environmental, energy, new technology, and regulatory matters are discussed. The book should be of interest to general readers and scientists and students as well as industry and government agencies concerned with energy and ocean management. NGH is a solid crystalline material that compresses gas by about a factor of about 164 during crystallization from natural gas (mainly methane) - rich pore waters over time. NGH displaces water and may form large concentrations in sediment pore space. Its formation introduces changes in the geotechnical character of host sediment that allows it to be distinguished by seismic and electric exploration methods. The chemical reaction that forms NGH from gas and water molecules is highly reversible, which allows controlled conversion of the NGH to its constituent gas and water. This can be achieved rapidly by one of a number of processes including heating, depressurization, inhibitor injection, dissolution, and molecular replacement. The produced gas has the potential to make NGH a valuable unconventional natural gas resource, and perhaps the largest on earth. Estimates for NGH distribution, concentration, economic targets, and volumes in the Arctic Ocean have been carried out by restricting the economic target to deepwater turbidite sands, which are also sediment hosts for more deeply buried conventional hydrocarbon deposits. Resource base estimates are based on NGH petroleum system analysis approach using industry-standard parameters along with analogs from three relatively well known examples (Nankai-Japan, Gulf of Mexico-United States, and Arctic permafrost hydrate). Drilling data has substantiated new geotechnical-level seismic analysis techniques for estimating not just the presence of NGH but prospect volumes. In addition to a volumetric estimate for NGH having economic potential, a sedimentary depositional model is proposed to aid exploration in the five different regions around the deep central Arctic Ocean basin. Related topics are also discussed. Transport and logistics for NGH may also be applicable for stranded conventional gas and oil deposits. Arising from a discussion of new technology and methodologies that could be applied to developing NGH, suggestions are made for the lowering of exploration and capital expenses that could make NGH competitive on a produced cost basis. The basis for the extraordinarily low environmental risk for exploration and production of NGH is discussed, especially with respect to the environmentally fragile Arctic region. It is suggested that because of the low environmental risk, special regulations could be written that would provide a framework for very low cost and safe development.

Tundra Disturbances and Recovery Following the 1949 Exploratory Drilling, Fish Creek, Northern Alaska by Daniel E. Lawson Pdf
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.
Arctic Offshore Engineering by Andrew Clennel Palmer,Ken Croasdale Pdf
There is an increasing need to construct engineering structures in the Arctic sea. The requirement is principally generated by the oil and gas industry, because of the substantial reserves that are known to existing offshore in the Beaufort Sea, the Caspian Sea, the Barents Sea, the Pacific Ocean off the cost of Sakhalin, the Canadian Arctic, and almost certainly elsewhere. Structures have to withstand the severe environmental forces generated by sea ice, a subject that is developing rapidly but is still far from completely understood. Underwater pipelines have to be safe against ice gouging and strudel scour, but also have to be constructed safely and economically. The social and human environment has to be understood and respected. This important book intentionally takes a broad view, and vividly accounts for the many and often subtle interactions between the different factors. It is illustrated by case studies of actual projects.
