ABSTRACT:
A method and apparatus for detecting the thermal characteristics of a subsurface formation in situ wherein a borehole has been drilled from the earth's surface, including inserting a known volume of cryogenic material into the borehole to a predetermined position in the formation to produce a zone of cooling in the formation thereabout; conducting test energy, subject to change by passage through a cooled medium of conduction, from a predetermined position in the borehole below the zone of cooling along a plurality of paths through and laterally of the zone to the surface; sensing the changes in the energy incident to passage through the zone at predetermined positions on the surface laterally of the borehole; calculating the volume of the zone from the known and acquired information to determine the thermal conductivity of the formation; and noting the time required for the known volume of cryogenic material to be boiled off by the formation to determine the latent heat of the formation.
