Key Features

Mechanical Setting Technology

Saga PCE’s mechanical liner hanger systems utilize string manipulation for reliable setting without hydraulic ports:

Rotation-Activated Setting – Right-hand rotation and set-down weight sequence engages slips against cones for positive engagement
Solid Body Mandrel Design – No hydraulic setting ports eliminates potential leak paths for enhanced pressure integrity
Bearing Assembly Integration – Optional bearing systems allow liner rotation in set position during cementing operations

Hydraulic Setting Technology

Our hydraulic liner hanger designs provide pressure-activated setting for challenging well conditions:

Differential Pressure Activation – Hydraulic cylinder setting mechanism operates via applied surface pressure without string manipulation
Heavy-Duty Slip Design – Robust slips withstand hours of rotation during deployment in rough formations with high solids content
High Bypass Flow Area – Staggered slip configuration maximizes annular flow during running and circulation operations

Liner Top Packer Integration

Integral Packer Systems – Compression-set liner top packers provide annular seal between liner and parent casing
High Seal Capacity – Packer elements qualified per API 11D1 testing for pressure and temperature performance
Hold-Down Slip Systems – Prevents packer element extrusion under differential pressure during production operations
Tieback Receptacle – Standard connection accepts extended length tieback sleeves for wellhead suspension systems

Superior Hanging Capacity and Temperature Performance

Saga PCE’s liner hanger systems feature optimized slip design and material selection to deliver reliable load support across the full spectrum of well conditions. Our engineering approach balances hanging capacity with deployment reliability to ensure liners reach setting depth and remain securely anchored throughout well life.

Ultrahigh Hanging Capacity – Slip configurations designed for load capacities from light (50,000 lb) to heavy (500,000+ lb) applications
Pressure Rating Envelope – Available in moderate (10,000 psi / 300°F) to extreme HPHT (15,000 psi / 450°F) configurations
Low-Profile Slip Design – Streamlined slip geometry reduces damage risk during deployment in tight clearance well
Geothermal Application Rating – High-temperature elastomers and metallurgy for geothermal wells exceeding 400°F
Extended Length Tieback Sleeves – Custom tieback receptacles accommodate varying liner lap lengths and wellhead requirements
Proprietary Reamer Shoe Integration – Compatible with Saga PCE reamer shoes for challenging liner running conditions in unstable formations

Applications

Load Support and Casing Extension

Saga PCE’s liner hangers suspend liner weight from parent casing:

Extending wellbore depth beyond previous casing shoe without running full casing string to surface
Supporting liner weight during cementing operations while maintaining string tension
Providing mechanical anchor point for tieback systems connecting liner to surface wellhead

Annular Sealing and Pressure Isolation

Optimized for creating pressure barriers in liner lap sections:

Integral liner top packers sealing annulus between liner and parent casing to prevent fluid migration
Isolating liner lap from formation pressures during production or injection operations
Enabling independent pressure testing of liner string before production operations commence

Rotation During Cementing

Engineered to improve cement placement quality through liner movement:

Rotating liner during cement displacement to create turbulent flow improving mud removal efficiency
Distributing cement uniformly around liner circumference in deviated and horizontal sections
Preventing cement channeling by mechanically disrupting preferential flow paths during displacement
