Abstract:
1. A system for acquiring data from a heat affected zone associated with a thermal recovery hydrocarbon reservoir in a subterranean formation that is intersected by a wellbore, comprising: a casing cemented in the wellbore; a primary tubing string in the wellbore; a coiled tubing string positioned along the primary tubing string; a locking assembly releasably coupling the primary tubing string to the coiled tubing string, the locking assembly configured to be responsive to a signal transmitted from the surface; a processor positioned at a selected location along a wellbore that intersects the reservoir, the selected location being substantially outside of the heat affected zone; a plurality of sensors distributed along the primary tubing string and at least partially along the heat affected zone; and a data link coupling the processor to a surface interface.
