... area requires the consideration of design conditions that do not apply elsewhere, such as ice gouging, frost heave and permafrost. Advanced numerical analysis is apt to play an important role in addressing these challenges and to bridge the technology gaps that still exist in order to enable optimized...

... and installation planning. Having this understanding will help better prepare an organization for permitting approvals and for adjustments once the non-technical risks and external input are considered. traffic unstable permafrost construction upstream oil & gas vehicle airstrip river northwestern...

... infrastructure development is critical to the successful development of the sensitive Arctic environment especially true in light of ongoing climate change where the melting of permafrost poses significant issues for development in the Arctic. The harsh Arctic environment presents unique challenges...

... such as strudel scour, permafrost thaw settlement, and ice gouging. These evolving design methodologies are comprised in INTECSEA's in-house suite of Arctic Tools and pipeline design standards. Focus is also placed on the importance of appropriate environmental and geotechnical data collection, the use of limit...

... Abstract Permafrost thaw induced settlement is a major concern for pipeline design and operation in the Arctic region. For a buried warm pipeline in permafrost, heat losses can thaw the frozen water in the surrounding soil and create a thaw bulb around the pipeline. The underlying soil...

... Abstract A man-made island and buried subsea pipeline are needed for an oil production project within the Foggy Island Bay area of the Alaskan Beaufort Sea. In order to characterize the geologic and permafrost conditions in the area, field data have been collected over several winter field...

... Abstract Thaw subsidence can damage the infrastructure including buildings, roads and airfields founded on ice- rich permafrost, increase their maintenance costs, change the landscape and influence the sustainable development in the northern region. Information about the ground movements...

... Abstract Permafrost in Arctic is one of the most important factors when exploration and production of gas and gas condensate fields due to its sensitivity to any technogenic (humane-made) impact or climatic change. Exploration and production procedures in the areas with instable permafrost...

... Abstract In conjunction with the development of a LNG storage tank facility in Fairbanks, Alaska a geotechnical investigation and probabilistic seismic hazard analysis (PSHA) was performed. The site is located within a region in Fairbanks where warm permafrost soils exist (-1°C average soil...

... Abstract Pipelines in the Arctic must contend with a variety of geotechnical obstacles affecting their construction and long-term operation. For example, thawing permafrost leads to unstable terrain, especially on slopes and pipeline river crossings. Research funded by the US Department...

... Abstract Buried pipelines in permafrost may undergo thaw settlement over a period of time. It depends on the type of soil. The innovative technology outlined in this paper solves the problem of thaw settlement of buried pipelines. With this technology expensive soil exploration...

... Abstract This paper presents a compendium of applications for thermosyphon type passive refrigeration devices for onshore facilities in the arctic. It's very seldom that thaw-stable permafrost or rock is available to found structures on and facilities need to be located on permafrost...

... Abstract In Arctic regions, permafrost and gas hydrate bearing sediments below the seabed present a technical problem for drilling operations. The first and most important challenge is to be able to control the well if pressured gas is encountered in or below such formations, and the second...

... Abstract Hole enlargement is a serious problem while drilling in permafrostconditions. The hole enlargement problems leads to lost circulation. Irregularand unstable holes also affect the quality of cement jobs. The drilling fluidis generally at a higher temperature than the permafrost...

... Abstract The development of arctic resources requires wells to be drilled, cased, andcemented through permafrost. Permafrost presents unique challenges, especiallyto cementing operations, requiring a cement system with the capability toperform in the subfreezing permafrost environment...

... Abstract Oil and gas producers have shown renewed interest in developing reservoirslocated both onshore and offshore within the Arctic regions of Alaska, Canadaand Russia. In many cases, the hydrocarbon reservoirs are known to be overlainby a massive permafrost interval that extends over...
