ConduCTor Wellhead running Tool

The Dril-Quip Conductor Wellhead Running Tool features a cam-actuated locking mechanism and low friction bear-ing surfaces that minimizes torque while the tool is being released from the conductor wellhead. Five rotations of the running string lock and release the tool to and from the wellhead. The running tool is unaffected by ambient pressure and cannot get “pressure locked.” An ascending/descending indicator rod is used to provide visual confirmation of the tool’s lock or unlock status.

feaTures

• Runs wellhead housing and guide base in one trip

• Removable plugs provide large flow-by area for returns while jetting or turbo drilling

18 3/4" Wellhead Running Tool

The running tools are unaf-fected by ambient pressure and have ample air exhaust and/or jet return ports.

feaTures

• Cam-actuated mechanism is not affected by water depth

• Lock/unlock indicator rod allows visual confirmation of tool status

• Low friction-bearing surfaces to carry tensile and bend-ing loads and to ensure easy release even under high bending moments

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 well-head 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 anti-rotation 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.

Cam-aCTuaTed drill-ahead (Cada) running Tool

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 and cleared prior to drilling ahead

nominal bore proTeCTor

Dril-Quip’s Nominal Bore Protector (NBP) protects the sealing surfaces in the wellhead ID when the 16" or 13 3/8" hole section is being drilled. O-ring seals on the OD of the NBP provide a trash barrier and lock the NBP into the wellhead.

Wear bushing After installing a casing hanger, the Wear Bush-ing is run to protect the wellhead ID during the drilling operation. Wear Bushings are available in a variety of sizes to match the casing program and casing hanger size specified. BOP stack testing can be performed with the Wear Bush-ing installed. Each Wear Bushing is locked to the wellhead with eight spring-loaded shear pins.

speCial bop TesT Tool

Dril-Quip’s Special BOP Test Tool allows testing of the BOP stack with the Nominal Bore Protector installed. The tool is designed to isolate the Nominal Bore Protector and transfer the loads of the BOP test into the wellhead.

feaTures

• Allows testing the BOP stack with the Nominal Bore Protector installed

• Seal element activation mechanism does not allow seal element to prematurely set

• Ample flow-by area facilitates running and prevents swabbing when the tool is retrieved

BOP Isolation Test Tool

bop TesT Tools

bop isolaTion TesT Tool

The BOP Isolation Test Tool is a weight-set tool that allows testing of the BOP stack and the wellhead housing while drilling. The BOP test tool seals on the ID of the wellhead and cannot be pre-energized. The seal element can only be activated when a release ring engages a known bore in the wellhead, wear bushing or casing hanger.

feaTures

• Allows testing of the BOP stack and the wellhead after removal of the Nominal Bore Protector (a slip-on adapter allows landing of the tool on the primary shoulder of the wellhead)

• Allows testing of the BOP stack with any wear bushing installed (this method tests the BOP

stack while isolating the casing hanger seal assembly from test pressure)

• Can be landed on top of a casing hanger with the wear bushing removed (the seal assembly is isolated from test pressure)

• Seal activation mechanism does not allow premature activation of the seal element

• Ample flow-by facilitates running and pre-vents swabbing when the tool is retrieved

ss-series loW-pressure supplemenTal Casing hangers

The low-pressure supplemental casing hanger is used for intermediate conductor strings in a variety of configurations and is run outside of BOP control.

feaTures

• Runs on a cam-actuated drill pipe tool and lands in 30", 36" or 38" supplemental adapter

• Automatically locks down to supplemental adapter with a self-locking retaining ring, which can support sinking primary conductor pipe up to 1.3 million lbs

• Incorporates either flow-by or annulus sealing

ss-series 20" x 16" (5,000 psi h2s serviCe)supplemenTal Casing hanger sysTem

Dril-Quip’s standard 20" x 16" Supplemental Casing Hanger System provides a means of installing and sealing supple-mental casing strings in the standard wellhead system. The 16" supplemental casing hanger and seal assembly is run on a cam-actuated running tool, landed, cemented, seal assembly weight set and tested all in one trip inside BOP control.

feaTures

• Weight-set metal lip elastomeric seal assembly that locks to casing hanger but can be retrieved and then run separately

• Multiple load shoulder profile of the split ring mechanism automatically engages match-ing profile in adapter, providing a positive landing point for the casing hanger

• Shear pins automatically lock casing hanger down, provide overpull verification to confirm casing hanger is properly landed, and prevent casing “float” during cementing operations

• Large flow-by areas around casing hanger for cementing operations

• 20" x 16" casing hanger adapter can be located anywhere in the 20" casing string, thereby reducing the amount of 16" casing needed
