Instrumentation Around a Warm Oil Pipeline Buried in Permafrost
A section of an uninsulated pipeline, 90 ft (27.4 m) long and 2 ft (0.61 m) in diameter, was buried in ice-rich permafrost at the Mackenzie Valley Pipe Line Research Limited Inuvik Test Facility. Oil at 160 °F (71 °C) was circulated through the pipe from July 1971 to January 1972 causing a thaw bulb...
