Abstract: Hydrocarbon recovery can involve operating flow control devices distributed along a horizontal well based on temperatures of hydrocarbon-containing fluids at a plurality of locations along the horizontal well. The temperatures of hydrocarbon-containing fluids can indicate a presence of a hotter overlying reservoir region and an adjacent colder overlying reservoir region. The operation of the distributed flow control devices can involve reducing flow of hydrocarbon-containing fluid from the hotter overlying reservoir region into the horizontal well, while providing fluid communication and pressure differential between the colder overlying reservoir region and the production well, sufficiently to cause hot fluids surrounding the colder overlying reservoir region to be drawn into and induce heating of the colder overlying reservoir region.
