Abstract
A method and apparatus for the injection of steam into a hydrocarbon well during a Steam Assisted Gravity Drainage (SAGD) process are provided. The apparatus can include a shifting sleeve positioned within the body of the apparatus. The shifting sleeve can have an open and a closed position. In the closed position annular seals can substantially prevent steam within the bore of the body from exiting the device and flowing into the wellbore. When the shifting sleeve is moved to its open position, an aperture in the body aligned with a steam dispersing cover mounted on the body can be exposed to pressurized steam from the bore of the apparatus and can allow steam to exit the bore and be dispersed into the wellbore. The steam dispersing covers can have dispersion openings which can direct the steam into the wellbore as desired.
