Hydraulic Liner Hanger System

MACKERAL’s  Hydraulic  Set  Liner  Hanger  is  an  economical,  medium  duty  hanger  that  is ideal  for  deviated  or  horizontal  wells.  This  is  set  hydraulically  by  applying pressure  through  the  running  string.  A  setting  ball  is dropped  to  a ball seat built within the landing collar. Applied pressure acts on the internal piston, moving slips up the cone to the set position. The  piston  seals  are  glass-filled  Teflon  for  higher  pressure  and  temperature ratings. A high-strength AISI 4140 alloy hydraulic cylinder is used to provide high burst & collapse  rating  to  meet  customer’s  requirement.  The  Hanger provides  full  bypass  in  the  set  position  during  cementing  operations.  The hydraulic  cylinder  is  safety  pinned  to  actuate  at  a  regulated  &  predefined setting force. The hanger body is furnished with higher group of API 5CT standard materials as well as with the end connections in conformity to API standards or any premium threads  as  per  the  customer’s  requirement.

Features / Benefits:
• Multi-cone design provides maximum bypass area.
• No pipe manipulation required to set hanger.
• Hanger sets with applied hydraulic pressure.
• Premium Teflon seals for high temperature/pressure applications.
• Large slip area supports long/heavy liner loads.
• Shear mechanism pretested for downhole reliability.
• Ideal for highly deviated or horizontal applications.

Applications:
Non Rotational Hydraulic Liner Hanger is used to hang a liner in well without rotating the work string to set the hanger. The hydraulic liner hanger is recommended for applications such as setting new liner through existing liners or on floating rigs. Few more applications of liner hanger as here under:
• Case off open hole more rapidly and easily.
• Deepening of old wells.
• Drilling with tapered drill string.
• To accomplish a side track from vertical hole.
• Testing of lower zone of new well before plugging back to primary pay.

MI 5168 HYDRAULIC RELEASE
LINER HANGER RUNNING TOOL

MACKERAL’s  Hydraulic  Release  Setting  Tool  connects  to  Liner  Setting  Sleeve  profile  provides  a means to carry a liner down hole, set a liner hanger and release from the liner prior to or, if desired, after cementing.
The primary releasing mechanism is hydraulic with an emergency mechanical back-up release system. This tool carries the weight of the liner on a fully supported collet assembly with no threads that could back off and drop the liner while running in the hole. High torque ratings of the Hydraulic release Running Tool system allow aggressive rotation if required to work a liner to bottom.
Features:
1. Emergency Back Up release system.
2. High torque rating.

MI 5170 HYD. ROTATING
LINER HANGER RUNNING TOOL

MACKERAL’ s Running Tool is used to run Rotating Liner Hangers. The Running Tool is provided with spring loaded dogs. The dogs engage with splines of setting collar to provide rotation to the liner hanger during running in and after setting of slips. The tool Kelly has 2 feet stroke, which allows rotation in tension or compression. The tool has provision in the bottom to connect the slick joint for cementing.
Running tool is also used to run and set Mechanical Set Liner Hangers. The tool is released mechanically by giving right hand rotation to the drill string.
