Ball Seat Landing Collar
Product Overview
The Ball Seat Landing Collar is a critical component in liner hanger assemblies, installed near the bottom of the liner string. It enables the landing of a ball to hydraulically set uphole tools during liner deployment and provides a secure profile for latching the liner wiper plug during primary cementing. The integrated clutch design prevents plug rotation during drill-out, ensuring a clean and efficient operation.
Key Features
- Field-adjustable ball seat pressure without disassembly (up to 5,000 psi)
- Contained ball and seat after shearing – no debris enters the wellbore
- Aluminum internals are fully PDC drillable
- Integrated wiper plug latch profile with anti-rotation clutch
- Maintains full casing ID after drill-out
Applications & Completion Scenarios
- Used in hydraulic-set liner hanger systems
- Effective in primary cementing operations requiring plug latching and anti-rotation control
- Suitable for wells where clean drill-out and debris control are critical
Advantages
- Field-adjustable shear system reduces redress time
- Contained debris system enhances reliability of float equipment
- High-strength housing matches liner metallurgy for structural integrity
Compatibility
Compatible with industry-standard hydraulic liner hanger systems, liner wiper plugs, and float equipment.
Certifications & Quality Assurance
Manufactured from premium-grade materials and tested to meet or exceed API and ISO performance standards for liner equipment.
