Ball-Drop Multi-Stage Frac Sleeve
Product Overview
The Ball-Drop Frac Sleeve is a field-proven mechanical actuation sleeve engineered for efficient, zone-by-zone hydraulic stimulation in horizontal wells. Designed to deliver sequential, toe-to-heel activation without wireline intervention, enabling fast, cost-effective multistage fracturing.
Key Features
- 10,000 PSI differential pressure rating for demanding frac environments
- 50+ stages with progressive ball-to-seat activation
- Full casing ID after drill-out for unrestricted post-frac access
- Field-adjustable opening pressure for operational flexibility
- Compatible with dissolvable or composite frac balls
Applications & Drilling Scenarios
- Open-hole, uncemented multistage isolation systems
- Cemented multistage completions
- Wells requiring predictable, sequential stimulation
- Fracturing programs seeking to eliminate wireline intervention
Advantages
- Simplified mechanical actuation for predictable zone activation
- Compact sleeve design improves handling and deployment efficiency
- Flow-area-optimized ports ensure high frac rates with reduced restrictions
- Fully drillable for fast post-frac cleanup
Compatibility
- Works in both open hole and cemented installations
- Compatible with dissolvable and composite ball systems
- Integrates with flexible completion architectures across Frontier’s Multi-Stage Sleeve portfolio
Certifications & Quality Assurance
- Manufactured with L-80 and P-110 materials under strict QC standards
- API-aligned metallurgy and elastomer specifications (where applicable)
