Title:
IN SITU THERMAL PROCESSING OF A HYDROCARBON CONTAINING FORMATION VIA BACKPRODUCING THROUGH A HEATER WELL
Document Type and Number:
WIPO Patent Application WO2003036038
Kind Code:
A3
Abstract:
A process for producing hydrocarbons through a heater wellbore positioned in a hydrocarbon containing formation. The in situ treatment process may include providing heat from one or more heaters to at least a portion of the formation. The heat may be allowed to transfer from one or more heaters to a selected section of the formation. Heat that is allowed to transfer to the selected section may pyrolyze at least some of the hydrocarbons within the selected section. The process may include selectively limiting a temperature proximate a selected portion of a heater wellbore to inhibit coke formation at or near the selected portion.
