and cannot get “pressure locked.” An ascending/descending
indicator rod is used to provide visual confirmation of the
tool’s lock or unlock status.

working pressure and H2S service.
The standard 18 3/4" wellhead has a primary landing shoulder
in the lower ID that supports up to a 7 million lb load,
created by a combination of casing weight and BOP stack
pressure test. The SS-15 Wellhead Housing is long enough
to contain a three-casing-hanger program plus a subsea
tubing hanger.
Features
• The 18 3/4" wellhead can be provided with a Dril-Quip
DX®, H-4, or CIW hub-type locking profile
• The 18 3/4" wellhead has a primary landing shoulder on
the lower ID to allow all casing weight and pressure
loads to be carried at the bottom of the wellhead
• The wellhead minimum ID will pass a 17½" bit and is
available with a variety of buttweld
prep sizes and wall thicknesses
• The 18 3/4" wellhead has a seal area
located in the top ID that allows the
wear bushing to remain in place
while testing the BOP stack with
the BOP isolation test tool
• The lower OD of the 18 3/4"

Rigid Lockdown Conductor Wellheads
Dril-Quip’s Rigid Lockdown (RLD) Conductor Wellhead is designed
to eliminate any alternating load between the conductor wellhead/
high pressure wellhead locking interface. This makes the RLD system
particularly suitable for well development applications, and is used for
most deepwater applications. Working with the preload features of the
18 ¾" RLD high-pressure wellhead housing, the dual running grooves at
the top and the five degree tapered interface at the bottom of the wellhead conductor housing lock the two housings together with up to 2
million lbs of preload, which increases the bending resistance and fatigue
life of Dril-Quip’s RLD Wellhead System.
The RLD Wellhead Housing incorporates a dual groove profile and antirotation slots for the cam-actuated drill-ahead running tool. In addition,
it includes a lockdown groove for the 18 ¾" housing and
can be adapted for a variety of conductor sizes.

The Dril-Quip CADA Tool incorporates all the features of the
standard conductor wellhead running tool. In addition, the
CADA Tool allows the operator to drill the next hole section
(once the conductor wellhead is installed) in the same trip.
Spring-loaded shear pins trap the outer body in the conductor
wellhead to act as a centralizer bushing during the drill-ahead
phase, and allow the body of the tool to be sheared out of the
wellhead when the tool is retrieved.
Features
• Simple right-hand rotation puts tool in drill-ahead mode
• Includes large flow-by area for returns while jetting and
drilling ahead
• Allows passage of 10" drill collars
• Simple overpull retrieval process to recover tool back
to the surface
• Has a 10" stroke to allow bottom hole assembly to be raised
