Inline RF heating for SAGD operations

摘要

A method is described for accelerating start-up for SAGD-type operation by providing radio frequency heating devices inside the lateral wells that can re-heat the injected steam after losing heat energy during the initial injection. The method also extends the lateral wells such that the drilling of vertical wells can be reduced to save capital expenses.

主权项

1. A process comprising:
a) extending a lateral well of a steam assisted gravity drainage operation within a hydrocarbon formation; b) inserting at least one radio frequency heating device into the lateral well; and c) operating the at least one radio frequency heating device along the lateral well to reheat steam in said extended lateral well.
