A heater is disclosed which comprises an electrical insulating material surrounding an annular heating element configuration; wherein there is no casing surrounding an annular heating element configuration.
A hydrocarbon containing formation may be treated using an in situ thermal process. Heat may be applied to the formation to raise a temperature of a portion of the formation to a pyrolysis temperature. Heat input into the formation may be controlled to raise the temperature of portion at a selected ...
A method is disclosed for treating a hydrocarbon containing formation in situ and producing a hydrocarbon fluid from the formation, which method comprises pyrolysing hydrocarbons present in the formation during the production of the hydrocarbon fluid from the formation with the application of a pres ...
