18 " subsea WellHead Running tool
Dril-Quips 18" Wellhead Running Tool has a left-hand make-up, right-hand release, cam-actuated locking design. An indicator rod is used to determine lock/unlock status. The running tool is unaffected by hydrostatic pressure and has ample exhaust and fill ports. The Wellhead Running Tool is used to handle the 18" wellhead and when running the wellhead with the Mechanical Rigid Lockdown Tool.
18 " mecHanical Rigid lockdoWn Running toolThe 18 " Mechanical Rigid Lockdown Running Tool allows the running, installation and cementing of the 18 " Rigid Lockdown Wellhead System and 22" casing on drill pipe in one trip.
FeatuRes Operates in conjunction with the 18 " Housing
Running Tool and runs the 18 " wellhead equipped with the rigid lockdown system
Upward drill pipe pull functions master linkage to activate the rigid lockdown mechanism on the 18 " wellhead
Lockdown is verified with position indicator plate on the OD of the outer sleeve
Drill pipe overpull at wellhead creates preload between conductor and 18 " wellhead
Can create a preload up to 2 million lbs
Unlimited water depth rated no hydraulics required
The mechanical advantage of the system is such that for 175,000 lbs of drill pipe pull at the wellhead, a preload of 2,000,000 lbs is created between the low-pressure and high-pressure wellhead housings. After lockdown, the tool is stroked down to the start position and jayed back to the right. Cementing operations can commence at this time.
Once cementing is complete, the tool is rotated to the right five rotations to release from the wellhead and the Rigid Lockdown Tool is retrieved with a straight pull.

Dril-Quips LS-15 Liner Hanger System is available with all of Dril-Quips Wellhead Systems. The LS-15 Liner Hanger products are built to perform under a wide range of conditions, and are ideally suited for long reach, high angle, horizontal and ultra-heavy liner completions. This premium liner hookup incorporates many innovative tool designs, ensuring reliable operation and service in many of todays most demanding wells.
ls-15 system FeatuResThe LS-15 Liner Hanger System features field-proven technology that incorporates the following:
High strength, high pressure, high load-carrying capacity
Metal-to-metal annulus packer seal for high pressure service
No hydraulic or mechanical devices on the hanger body, minimizing leak paths
Large slip area and controlled friction minimizes stress in the supporting casing
All hangers are automatically centralized when C-ring slip is set
Bypass flow area is the same after setting the liner hanger slip as in the running position
Maximizes circulating flow-by areas for efficient cementing operations
The LS-15 Liner Hanger System can be sized and configured to customer specifications
ls-15 PackeR seal FeatuRes Integral, one-trip metal-to-metal sealing design
Anti-swab design for faster running speeds and higher circulating rates: resists mechanical damage while running
Standard service for many sizes is 10,000 psi at 400 F. Higher pressures are achievable and are only limited by the capacity of the packer mandrel and casing
Rotational oPtionWith the addition of a rotating bearing assembly, the LS-15 Liner Hanger can be rotated with the slips in the set position during the cementing operation. This feature can assist in completing a successful cement job.

Unique One-Piece C-Ring Slip
The liner hanger is run to total depth with the slip in the retracted, running position.
The hanger body is then slacked off onto the slip. The sharp teeth on the slip will secure the liner hanger to the supporting casing. At light loading, the dull inner slip teeth will not yet grab the cone as it slides behind the slip.
When released from its locked-down running-in position, the slip will spring open and come into contact with the ID of the supporting casing.
As the loading increases and travel pro-gresses, the inner teeth begin to form small shoulders on the liner hanger slip cone. As the shoulders increase in size, the downward travel of the liner hanger is stopped before loading gets high enough to collapse the liner hanger body or burst the supporting casing.

The LS-15 System Incorporates a Unique Hanger Slip DesignDril-Quips proprietary one-piece C-Ring Hang-Off Slip has been developed to greatly reduce the amount of hoop stress placed on the supporting casing by the liner load. Dril-Quips circumferential slip design distributes the liner load much more evenly around the casing than conventional multi-slip segment hanger systems. The C-Ring Slip also incorporates a method of controlling the friction between the slip and the hanger body. This controlled friction design redirects hoop load into axial load, drastically reducing the collapsing load on the hanger body and burst pressure on the casing. This combination of stress loading permits the LS-15 Liner Hanger System to hang longer and much heavier liners than possible with conventional technology.

ls-15 Running toolls-15 Running tool The system incorporates high torque capacity for drill-
down, wash-down applications and rotation during cementing operations
The Running Tool incorporates a port isolation system that eliminates the possibility of prematurely setting the slip, or releasing from the hanger while running into the hole
The hydraulics to set the liner hanger slip are built into the Running Tool, not as part of the hanger system, eliminat-ing the need for a hydraulic port through the body of the liner hanger
The Running Tool is hydraulically released from the liner hanger and also incorporates a unique right-hand hydro-mechanical secondary release
Running PRoceduResIn order to solve many of the problems encountered during liner 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 ball to seat in running tool.
3. Pressure to 1,000 psi, shift the port isolation sleeve and release liner hanger slip, slack off liner weight onto slip.
4. Pressure to 2,000 psi to release running tool from liner hanger.
5. Reduce drill pipe pressure to 500 psi to accomplish soft release of setting ball. Pick up drill pipe string approximately 4" to check for release of running tool, which is confirmed when drill pipe pressure bleeds off.
6. Slack off weight onto hanger to reseat running tool. Reestablish circulation, pump cement.
7. Launch pump-down plug from cementing manifold and displace to liner wiper plug.
8. Pressure to 1,000 psi, release the liner wiper plug from the running tool.
9. Continue fluid displacement and pump the plug set to landing collar.
10. 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 and testing the packer seal.
12. Pull out of hole with running tool.

dril-Quips 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-Quips 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.
Dril-Quips Cementing Manifold is compact and easy to operate to facilitate liner hanger installation.
