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 1):
A process of steam assisted gravity drainage (SAGD) hydrocarbon production, comprising:\n providing a horizontal production well with production tubing and a horizontal injection well with injection tubing, wherein said injection and production tubing are parallel and have a vertical spacing of 3 meters or less in a subterranean hydrocarbon-containing reservoir; injecting steam into said injection well, wherein at least one of said injection tubing and/or said production tubing has one or more flow control devices that restricts the flow of steam vapor; controlling the flow of steam with said one or more flow control devices to maximize steam chamber growth, wherein said flow control devices restrict significant flow of steam vapor into said horizontal production well by causing an increased pressure drop with localized high flow rate or by discriminating between live steam vapor and liquid water or oil such that live steam vapor is met with much higher pressure drop, and producing hydrocarbons from said production well, wherein the injection and the producing occur without a startup period.
