III. Liner Systems - b.2.2. Eagle Dual Cone Hanger - Hydraulic
The hydraulically set Eagle Dual Cone Hanger by Allamon Tool Company is the best choice for medium to heavy liners run in wells deviated more than 35 degrees that do not require a liner top packer for annular isolation. This hanger provides all of the same features and benefits of the Eagle Single Cone Hanger except that it is designed with two sets of hanging cones and slips in order to provide higher hanging capacities for a greater range of applications. It is set via applied pressure internal to the workstring. There is no required manipulation of the workstring other than simply slacking off onto the slips once the setting pressure is reached. When run in combination with Allamon Tool Company’s plug systems, the setting ball is caught in the plug running tool which means that there is greatly reduced risk in damaging the formation after setting the hanger and releasing the setting ball. This hanger is robustly designed for installation in highly deviated wellbores up to and beyond 90 degrees of deviation and because of the single cone arrangement is rated for use with light to medium liner loads.
Features/Benefits
  • Lay-down slip profile reduces risk for damage during installation
  • Semi-slip feature provides better initial ‘bite’ and better load disbursement
  • Provides excellent circulating by-pass area
  • Return piston provides collapse rating equal to that of the liner
  • Setting ball shears out in running tools for lower formation surge
