  • Publication number: 20130186623
    Abstract: The present invention generally relates to injecting steam into a wellbore using a device. The device includes a body having a bore configured to communicate steam through the body. The device also includes a sleeve movable in the bore of the body between a first position and a second position, wherein the sleeve in the first position blocks steam from exiting an opening of the body and the sleeve in the second position allows steam to exit the opening of the body. The device further includes a shroud disposed on a portion of the body such that an annulus is formed between the shroud and the body, wherein the annulus is configured to direct steam from the opening in the body toward steam outlets. In another aspect, a method of injecting steam into a wellbore using a steam tubular is provided.
