Abstract
A heating and distributed-temperature-sensor cable permanently fixed in a wellbore that permits known amounts of heat to be introduced to subsurface formations and improved temperature measurement thereof. The heat is introduced into a target zone of the wellbore by forming the cable in two sections: an upper section that carries an electrical current without generating significant amounts of heat, and a lower section that generates heat from the electrical current. Continuous distributed-temperature-sensing is performed through measuring various scattering mechanism in optical fibers that run the length of the cable.
