Liner Hanger Systems

•  The Non-Rotating Hydraulic Set Liner Hanger Integrated packer may be used to hang any type or size liner at any depth.
•  Body is manufactured from mechanical tubing to equivalent grade of liner 110,000 psi yield strengths is standard. 

•  Mechanical Set Liner Hanger (Single Cone) and (Double Cone)
•  Inventory Simplicity - For a given liner/casing size, the same can be run on the most exotic or elementary hook-up. 
•  No Casing Damage - At rated load capacities, it causes no plastic deformation.

•  Automatic J- cage, allows hanger to return to run-in position constraining hanger preset while running in.
•  Large bypass area in run-in and set position.
•  Available in all metallurgical con forming to NACE MR 0175 or H2S, and suitable for standard normal/ H2S, CO2 well services requirements 

•  The Mechanical Liner Hanger With Integrated Packer  provide an excellent seal that can be used to control annular gas migration or protect sensitive zones from well hydro- statics after cementing.
•  Tieback 10', 12’, 15' and 20' lengths standard.

•  Hydraulic Liner Hanger available in Rotating Non Rotating type design.
•  High performance Roller bearing enables rotation during running and Cementing for proper cementing operation. 

• Hydraulic Rotating liner hanger with integrated Packer has slip and cone designed for minimum casing stress levels.
•  High-performance, compression-set liner top packer.  

• Liner top Packer is used in Well application requiring hanging heavy liners. 
•  High pressure and High temperature wells. 
•  Vertical and horizontal wells. 
•  Offshore and Deviated Wells with  tight turns. 

•  HYDRAULIC LATCH LANDING COLLAR: Ceramic Ball Seat - A ceramic insert has been incorporated into the ball seat of most standard sizes in order to eliminate erosion.
•  Drillable - The inserts in these tools are made of drillable cast Aluminium for easy drill out 

• Gradwell - HR Running Tool is useful in high pressure and High temperature wells.
•  Easy stub-up to load the HR setting tool into the HR liner Setting sleeve. Simply push straight in and setting tool automatically latches.

• High strength Spring loaded Dogs Apply set down weight to set Liner Top Packer.
• Available in all API material grades.
• Available in all API Drill Pipe Threads.
• Suitable for H2S & CO2 service

• Used for liner and inner string cementing where top drive is available.
• It is reliable when high circulation and rotation at high RPMs for longer periods of time is required.
• Designed for high pressure applications up to 10,000 PSI.

• Composed entirely of PDC (polycrystalline diamond composite) drillable materials, the stinger dart enables trouble-free drill out, conserving rig time.
• PDP acts as a mechanical barrier between displacement fluids to prevent cement contamination, resulting in a clean pipe ID.

The Clean Out Mill assembly is used to clean the excess cement from the tie back receptacle after the cement job is performed. This is to prevent seal damage for and allow for good sealing of the seal stem run in thereafter. The POLISH Mill is designed with metal blade, which measure 1/16’’ less than the I.D of the TBR sleeve. It has an REG pin up and 2-7/8’’ REG 3-1/2’’ REG or 4-1/2’’ REG down depending on the size.

 The Top Dress Mill has a tungsten carbide NO-go which dresses off the TBR top very effectively. It has 4-1/2’’ regular Pin x Box connections. All parts are made of AISI 4140 ht high tensile material for heavy duty. The Polish / Dress Mill assembly is normally spaced out and made up in the Gradwell Workshop 

•  To isolate the liner top after the hanger is set and cementing operations are completed 
•  Isolate formation pressure below the liner top from the casing ID above 
•  Isolate treating pressures below the liner-top during fracture or acid work 
•  It can be used as a tie-back completion or production packer.
