WellMaster™
Remote Control TopDrive Cementing Head enhances cementing quality and safety while saving valuable rig time SurgeMaster™ II Multipleopening Diverter Tool reduces surge pressure and mud loss while increasing casing and liner running speeds
Running tools provides superior primary cement placement when run with liner-hanger system to separate fluids while cementing
SSR™ Sub-Surface Release™ plug system provides superior primary cement placement when run with liner-hanger system to separate fluids while cementing
– Maintains well control because it is the only system to run in the closed position – The tool allows fluid flowing up the ID of the casing to exit into the annulus between the running string and the previously run casing. – Reduces surge pressure, formation damage, and associated mud losses – No shock waves are created from tool activation or passage of balls and darts – Overfilling is avoided

WellMaster™ Deepwater System
What can it do for you
• Gets casing or liner to TD faster in wells with close-tolerance casing designs • Reduces surge pressures that cause excessive mud loss and formation damage • Increases safety by improving well control and reducing the number of onsite personnel • Significantly reduces risk and potential cost of failure when running close tolerance string of pipe • Saves you money by providing higher quality cementing, and reducing construction costs and operational mistakes

SurgeMaster™ II Multiple-Opening Diverter Tool SurgeMaster II reduces surge pressure on the formation and increases running speeds
WPHS Liner Hanger System high-torque rotation an high-circulation bypass slots enhance well cleaning, cement displacement, and zonal isolation
Performance-matched components With its multiple-opening diverter tool, high circulation liner-top packer, rotating liner hanger, full-bore access ball seat, sub-surface release plug system, high capacity auto-fill float collar, high-flow filter shoe, the WellMaster system is beyond compare in closetolerance annuli
We developed a large-bore system with components designed to reduce surge pressures. With compatible IDs, ODs, balls, drts, plugs, pressure regimes, everything works together from top to bottom to reduce surge, mud losses, and formation damage to get you to TD faster.

Floating Junk Bonnet (FJB)
• Run as part of the liner running tool assembly • Spring-loaded dogs form a no-go that will not reenter the PBR so that weight can be applied to the PBR to set the liner-top packer • Axial thrust bearing allows rotation of the drillpipe as set-down weight is applied • Used with a TSP4 or TSP5 liner-top packer

Rotating Packer Actuator
Allows weight to be set down through the PBR while rotating so that an integral liner-top packer can be set
Compact RC-TDH enhances cementing quality and safety while saving valuable rig time
• There are heads available with larger IDs and ratings over 2mlbs • Pre-loaded setting ball and darts • Remotely operated without breaking connection or shutting down cement pumps • Weatherford offers a complete line of subsea dart launch heads in standard and remote configurations
Prevents debris from entering the tie-back polished bore receptacle (PBR) during liner run-in, well clean up, and cementing
• Float on a cushion of fresh water between it and the cementing packoff. • Patented design prevents debris packing off around the tool and ensures optimal performance of the running tool • Spring sleeve and bypass channel allow fluid circulation to equalize during retrieval, minimizing retrieval force required • Can be backreamed through debris, ensuring successful retrieval of liner running tools

Dart Alignment Sub Package
Dart Alignment Sub Package allows smooth ID transition for SSR darts
• Run below RC-TDH or TDH to prevent darts from hanging inside one-piece canister style safety valves. • Darts can hang on shoulder preventing proper release of cementing plugs • Matched-pair package rented along with cement head.
