... would have to traverse the 2,000 ft (600m)-thick Permafrost layer. Unavoidable heat losses from the steam and production tubings have two detrimental effects: the injected steam quality is greatly reduced, and melting the Permafrost around the cemented casing could cause the well to sink...

... the VSMs were installed in, or adjacent to, the numerous shallow ponds or lakes that dot the tundra. Ponded water causes a condition where the local permafrost is warmer than the surrounding permafrost because much of the winter's cooling is absorbed by the phase change from water to ice and then lost...

... ABSTRACT The methods used for drilling and sampling of permafrost for site investigation purposes have evolved significantly during recent years. These changes are due in part to the development of new technology and equipment. A review of the applicability of current drilling and sampling...

... the foundation was placed consisted of relatively warm (30°F [−1°C]) permafrost consisting of ice-rich clay averaging 25%-50% total moisture. A 8.5 foot (2.6 m) thick insulated gravel pad was designed for the power plant foundation. A stress analysis for the foundation indicated that a stress of over 2900 psf...

... to Zama Lake in Northern Alberta, a total distance of 869 km through the discontinuous permafrost zone. The ditch was logged by experienced geotechnical field personnel every 50-100 m, depending on changing conditions. Every transition from unfrozen to frozen soil was logged based on visual criteria...
