Abstract
A well system for recovering hydrocarbons such as heavy crude oil from subsurface reservoirs is provided. The well system includes a single continuous wellbore extending from a surface entry opening to a surface exit opening. A substantially horizontal section of the wellbore is formed within the subsurface reservoir. In one embodiment, a plurality of heater-lifter units are movably disposed within the substantially horizontal wellbore section. The heater-lifter units are configured to apply heat to subsurface reservoir surrounding the substantially horizontal wellbore section to mobilize the hydrocarbons. A lifting mechanism is configured to move the heater-lifter units in bidirectional manner within the continuous wellbore so that the produced low viscosity hydrocarbons are mechanically lifted to the surface.
