Abstract: A method for installing a pipeline for transporting a warm fluid, such as newly-produced oil, across arctic seafloor underlain by a permafrost zone without danger of rupture of the pipeline caused by thawing in the supporting permafrost zone comprises (1) drilling a series of boreholes along the seafloor through a thawed zone of subsea soil so as to penetrate a distance into a zone of permafrost lying thereunder, (2) circulating a warm fluid through each borehole so as to cause a zone of prethawing in the permafrost zone and thereby create a slump trough on the surface of the seafloor along a path marked by the series of boreholes; and (3) installing a warm fluid bearing pipeline along the bottom of the slump trough. Usually a temperature differential between the warm fluid and the bottom of the borehole of at least 2 degrees Fahrenheit is required to assure economical prethawing of the permafrost zone.

Abstract: Corrosion and erosion of metal well casings due to production of corrosive well fluids, especially geothermal brines, is avoided by producing corrosive fluids through an impermeable cement wellhousing comprised of inner and outer substantially continuous cement liners which envelop and insulate from corrosion and erosion a conventional outer metal or other well casing while the outer casing internally reinforces the cement well housing. A second, sacrificial metal casing of smaller diameter is used in cementing the inner cement liner and can be substantially corroded away by corrosive fluids without substantial damage to the remaining cement wellhousing or outer casing through which corrosive fluids are produced. An apparatus for producing corrosive fluids, particularly geothermal brine, contained in a subterranean formation is also disclosed.

Abstract: A self-breaking, foamed, oil-in-water emulsion contains a water-immiscible organic solvent for paraffins and asphaltenes, an aqueous nonformation-damaging component, an inert gas, and surface active agents selected to promote a stable foamed emulsion despite contact of the treating fluid with the hydrocarbon and aqueous environment in the reservoir. Under conditions of agitation, the treating fluid is a stable foamed emulsion which undergoes spontaneous breakdown into two liquid phases under quiescent conditions. The treating fluid is injected and/or circulated as a stable foamed emulsion to dissolve paraffin and asphaltene-containing deposits from various substrata, such as a subterranean reservoir penetrated by a well, the well itself, or an industrial vessel or conduit. When injection or circulation is stopped, the foamed emulsion spontaneously breaks down so that the treating fluid can be readily pumped from the well.

Abstract: Hot, coarse, particles removed from a retort, preferably coarse particles of oil shale removed from a retort operating at superatmospheric pressure, are crushed to a size suitable for fluidization and then fed to a fluidization zone maintained under non-oxidizing conditions at substantially the pressure of the retort to forestall escape of retort gases. Raw fines are introduced into the fluidization zone and retorted without agglomeration using heat transferred from the hot retorted particles. Also introduced into the fluidization zone is a heated fluidizing gas stream comprised of recycle retort gas, which is employed to educe hydrocarbonaceous vapors from the fines and, optionally transfer heat. Educed vapors from the fluidization zone are recycled to the retort to be partially condensed and recovered as liquid and gaseous product streams along with other vapors educed in the retort.
