ABSTRACT:
The heat control production system and method for an oil well utilizes a noncorrosive gas compatible with crude oil fire hazards to provide an insulating annulus between the production tubing string of an oil well and the bore hole or casing or other tubing string surrounding the production tubing string by pressurizing the insulating annulus from the source of gas such that crude oil from the oil reservoir enters the insulating annulus and interfaces with the gas intermediate the surface and the oil reservoir whereby the insulating annulus provides minimal heat transfer to allow the crude oil produced through the production tubing string to reach the surface at a preselected temperature up to the oil reservoir temperature which avoids undesirable precipitation or gelling of paraffinic hydrocarbons from heat loss to the overburden of the oil well.
