Abstract
A downhole heating method comprises locating a heater in a fluid-filled downhole bore, activating the heater to heat the bore and the fluid therein, and restricting or disrupting convection-induced flow of the heated fluid in the bore. The convection-induced flow may be restricted by providing a radially extending flow barrier or heat deflector. Alternatively, or in addition, the flow may be disrupted by configuring a surface of the heater to disrupt axial flow.
