Abstract
Heated production well for enhancing production of hydrocarbons from a hydrocarbon reservoir are described. By heating the production well, heat is imparted to the reservoir and helps to mobilize the hydrocarbons and improve hydrocarbon production. A method of producing hydrocarbons from a hydrocarbon reservoir, includes using a heated production well positioned in the hydrocarbon reservoir, the heated production well having a higher temperature than the ambient temperature of the hydrocarbon reservoir.
Claims21
A method of producing hydrocarbons from a hydrocarbon reservoir, the method comprising:
- injecting fluid via an injection well into the reservoir;
- circulating a non-hydrocarbon based heated fluid through a production well to impart heat into the hydrocarbon reservoir;
- and
- producing hydrocarbons from the hydrocarbon reservoir to a production site,
- wherein the non-hydrocarbon based heated fluid has a higher temperature than the ambient temperature of the hydrocarbon reservoir.
A system for producing hydrocarbons from a hydrocarbon reservoir, the system comprising:
- a first injection well positioned in the hydrocarbon reservoir for injecting fluid into the reservoir;
- and
- a production well positioned in the hydrocarbon reservoir, the production well comprising a wellbore for circulating a non-hydrocarbon based heated fluid therein for imparting heat to the hydrocarbon reservoir and producing hydrocarbon from the reservoir,
- wherein the non-hydrocarbon based heated fluid has a higher temperature than the ambient temperature of the hydrocarbon reservoir.
