Abstract
Methods and systems are provided for monitoring subsurface steam chamber development in a thermal hydrocarbon recovery operation, which employ a fiber optic cable in a horizontal wellbore beneath the steam chamber as part of a distributed acoustic sensing technique in which the cable receives attenuated sound waves passing through the steam chamber and transmits a signal corresponding to the attenuated sound waves and unattenuated sound waves for subsequent signal processing.
