Abstract
The invention relates to a method for improved gravity drainage in a hydrocarbon formation, the method comprising: drilling a production well along a substantially horizontal production layer of a reservoir; drilling a perforation well above the production well, either in the production layer or in a layer separated from the production layer by a fluid barrier; perforating the formation adjacent the perforation well to provide a fluid flow path to or within the production layer; inducing gravity drainage through the fluid flow path; and producing fluids collected in the production well.
