<p>Smart shuttles (306) are used to convey into the steel pipe (664) the various smart completion devices (188) necessary to complete the oil and gas well. Smart shuttles (306) may be attached to a wireline (302), a coiled tubing (656), or to a wireline installed within coiled tubing. Of particular interest is a wireline conveyed smart shuttle (306) that possesses an electrically operated internal pump (402) that pumps fluid from below the shuttle (306), to above the shuttle (306), that in turn causes the smart shuttle (306) to 'pump itself down' and into a horizontal wellbore. Similar comments apply to coiled tubing conveyed smart shuttles.</p> |
