Abstract
A downhole injection apparatus having a sleeve disposed in a tubular housing. The sleeve and housing define an annular orifice through which steam flows prior to injection into the wellbore. Water condensate collects at the orifice or restriction proximate the orifice and is mixed with or entrained into the flow of steam. The sleeve preferably has a plurality of generally radial ports such that steam flows from interior the sleeve to the annulus. Preferably the injection ports and sleeve ports are angled to reduce or eliminate radical changes in direction of the steam flow.
