2 THE LINER HANGER DESIGNED FOR TODAY S WELL COMPLETIONS Featuring a simple design with fewer components, the torsionally set PowerScrew liner hanger offers outstanding ease of operation combined with a high degree of reliability and functionality. This advanced hanger system, employing a patent-pending stretch-forming technique, provides a superior connection between casing liners and intermediate casing strings. The PowerScrew s liner top combines profiled packer elements and hardened slip wickers, for reliable hanging and sealing performance. In addition, this advanced system s running tool delivers superior tensile, compressive, and torsional strength, providing for successful deployment and target placement of the liner every time. DESIGNED FOR EASE OF OPERATION AND RELIABILITY The PowerScrew was designed to address the most pressing issues in well completions today based on its operational efficiency, ease of running, and reliable setting process. The ease of operation is provided without sacrificing pressure containment, or hanging capacity. UNIQUE TORSIONALLY SET LINER HANGER Key Features: Many advanced liner hangers today require high hydraulic pressure for setting. By Unique metal-formed design using helical insets for additional strength comparison, the PowerScrew utilizes the energy from the top drive to set the tool safely Simple and reliable mechanical setting process and efficiently, eliminating the need for high setting pressure. Top drive rotation provides the energy to helically stretch-form the liner top, allowing the entire hanger body to form Integral hardened slip wickers combined with advanced, profiled Viton packing elements Setting tool employing planetary roller screw (high performance component adopted from the aerospace industry) Proven downhole diamond bearings used during the setting process against the casing wall. This process provides for improved pressure containment, higher Multi-lead rifling mandrel used in the setting tool, for greater collapse resistance hanging capacity, and an overall higher standard of reliability and safety. Polished Bore Receptacle located below liner top provides easy tie-backs TMK Ultra FJ premium connection used as an interface between the PBR and the liner top

3 POWERSCREW TORSIONALLY SET LINER HANGER The advanced PowerScrew liner hanger incorporates a number of key design features, providing for ease of running and setting combined with outstanding pressure integrity and hanging capacity. MLR super-finished mandrel provides low-friction helical stretch of liner top into parent casing Full packer seals protects against migrating gas Reliable preset pressurized release system Fluid film diamond thrust bearings Profiled packer seals protects against high hydraulic pressure Polished Bore Receptacle for consistent tie-backs Helically stretch formed liner top Planetary gears transfer torsional energy into linear force Integrated, hardened Slip Wickers for greater hanging capacity Unique Latch-Lock Downhole cementing liner wiper system Burst disks allow for pressure testing after setting

4 Pull Out Position Compression Liner Release OPERATING AND SETTING SEQUENCE The process of deploying and setting the PowerScrew Liner System is simple and straightforward. Using torsional energy from the top drive in the setting process, the PowerScrew does not require high pressure for setting that is needed by many conventional hanger systems. A spade-nose casing shoe is typically utilized in setting the PowerScrew. This casing shoe is made up to our unique Latch-Lock landing collar. The top of the PowerScrew is made up with a NC-50 connection, and is run into the hole on drill pipe to the setting depth. The liner is locked to the drill pipe through the PowerScrew and can be put in tension, compression, and torqued at will being respectful of the equipment s mechanical limits. Tag bottom and pick up the string to setting depth. With a rotating cement manifold in place, pump the cement into the drill pipe. Over-displacement of cement is not recommended. Switch the cement manifold to drilling fluids and pump the Latch-Lock dart between the two fluids. The dart will launch the cement plug at a predetermined pressure below the setting tool. Pump the Latch-Lock dart and plug assembly into the Latch-Lock landing collar. As pressure begins to spike, stop pumping the drilling fluid. Drop the steel setting ball and allow time to seat. Prepare for the metal forming process by putting the work string into compression and pressurizing the release mechanism. This action releases the liner from the PowerScrew setting tool. Apply torque to the string. With the liner released, torsional energy from the string is transferred to the liner top through the PowerScrew System s unique multi-lead rifled mandrel. The helically stretched liner top embeds hardened slip wickers with profiled packer elements directly into the intermediate casing. With a sudden drop in torque, the liner top is fully integrated into the intermediate casing. The PowerScrew setting tool is ready to be removed from the hole, and the liner is ready to be pressure tested. To pressure test the liner, the setting tool s burst-disks must be pressurized to allow circulation. The burst disks are set at a predetermined pressure. With circulation reestablished, the liner systems can be pressure tested at will. POWERSCREW SPECIFICATIONS FOR SETTING IN 9-5/8 in.
