Abstract: This application discloses a process for drilling and primary cementing a well using a drilling fluid containing a polymeric material which may be converted into a well cement by contact with an initiator and, optionally, by irradiation with a suitable radioactive source.
Abstract: A pipeline system which is capable of withstanding a range of extreme temperatures is disclosed. A pipe is surrounded by a vapor barrier which has a corrugated surface facing the pipe. The amplitude of the corrugations changes, absorbing the stress imposed by extreme temperatures, especially those at which liquefied natural gas is carried.
