The remote-controlled, multiangle bent sub for drilling trajectory control and corrections
A downhole, adjustable, multiangle bent sub, called Telepilote, has been developed for remote control of the wellbore path on a real-time basis without changing the general bottomhole assembly (BHA) configuration. Different modes of actuation for changing the bent sub correspond to different types of construction. The tool is available in 6 3/4-, 7 3/4-, 8-, and 9 1/2-in. (17.1-, 19.7-, 20.3-, and 24.1-cm) nominal sizes. It can be set at six positions, from zero (or straight position) to a maximum angle position of 2/sup 0/, 2/sup 0/30', or 3/sup 0/, according to nominal sizes. The main construction features and different drilling applications are presented. In addition, the T-3000 Telepilote is described, which features the Telehydrocom (THD) actuator system. This system makes an immediate, direct hookup in the drillstring between the sub and all survey instruments, including measurement-while-drilling (MWD) systems, possible.
