bull The system incorporates high torque capacity for drill-down wash-down applications and rotation duringcementing operations
bull The Running Tool incorporates a port isolation system thateliminates the possibility of prematurely setting the slipor releasing from the hanger while running into the hole
bull The hydraulics to set the liner hanger slip are built into theRunning Tool not as part of the hanger system eliminat-ing the need for a hydraulic port through the body of theliner hanger
bull The Running Tool is hydraulically released from the linerhanger and also incorporates a unique right-hand hydro-mechanical secondary release
RUNNING PROCEDURES
In order to solve many of the problems encountered duringliner installation DRIL-QUIP has simplified the running proce-dures of the liner hanger for exceptional ease of use
1 Trip into hole to liner-setting depth
2 Launch setting ball from cementing manifold pump ballto seat in running tool
3 Pressure to 1000 psi shift the port isolation sleeve andrelease liner hanger slip slack off liner weight onto slip
4 Pressure to 2000 psi to release running tool fromliner hanger
5 Reduce drill pipe pressure to 500 psi to accomplishsoft release of setting ball Pick up drill pipe stringapproximately 4 to check for release of running toolwhich is confirmed when drill pipe pressure bleeds off
6 Slack off weight onto hanger to reseat running toolReestablish circulation pump cement
7 Launch pump-down plug from cementing manifold anddisplace to liner wiper plug
8 Pressure to 1000 psi release the liner wiper plug from therunning tool
9 Continue fluid displacement and pump the plug set to
landing collar10 Pick up running tool to release packer setting assembly
and slack off weight to set packer seal
11 Pressure down the annulus to pressure assist setting andtesting the packer seal

DRIL-QUIPrsquoS Cementing Manifold is designed
with a unique head that contains four
pockets at circumferentially placed locations This
arrangement eliminates stacked-plug launching
heads and their corresponding height require-ments allowing for a more compact design The
operator can load releasing balls and pump-down
plugs in three of the four pockets easily on the
rig floor The manifold eliminates the need to
break any connections when loading and launch-
ing releasing balls or
pump-down plugs The
manifold allows circulat-
ing the hole through the
fourth bypass pocket
located in the head
DRIL-QUIPrsquoS Cementing
Manifold can be made
up in the string prior to
running the liner hanger
for ease of operations
and can accommodate
rotational torque so that
drilling the liner hanger into position if required
is not a problem
