Abstract:
Methods and systems related to SAGD injection and/or production wells that utilize flow distribution control devices. Additionally, methods and systems using limited vertical spacing separating the wells are described. These methods and systems improve steam assisted gravity drainage (SAGD) oil production, reduce SAGD start-up time and costs, and improve overall SAGD performance.

Claim (Index 13):
An improved method of SAGD production of hydrocarbons, said method comprising injecting steam into an upper horizontal well to heat hydrocarbons, allowing gravity drainage of heated hydrocarbons to a lower horizontal well, and producing said heated hydrocarbons from said lower horizontal well, the improvement comprising separating said upper horizontal well said lower horizontal well by \u22643 meters, and controlling the flow of steam in one or both of said wells using a flow control device to provide even distribution of steam along said in one or both of said wells and performing the producing step without a startup period.
