Collet-Actuated Multi-Stage Frac Sleeve
Product Overview
The Collet-Actuated Multi-Stage Frac Sleeve is a mechanically shifted stimulation sleeve engineered for precise, selective zone activation. Designed for wells with tight pressure windows or complex geometries, it enables controlled access to individual stages using coiled tubing or shifting tools—without the need for ball drops or hydraulic actuation.
Key Features
- Mechanical collet mechanism ensures precise, selective opening
- No pressure buildup required for actuation—ideal for pressure-sensitive wells
- Enables post-logging or post-drilling selective stimulation
- Compatible with standard coiled tubing shifting tools
- Suitable for deviated, tortuous, or extended-reach well paths
Applications & Drilling Scenarios
- Wells with limited pressure windows where ball-drop activation is impractical
- Post-drilling or post-logging selective stimulation operations
- Complex, highly deviated, or tortuous wellbores
- Operators requiring high control of individual stage access
- Re-stimulation programs requiring mechanical re-entry into selected stages
Advantages
- No reliance on pressure buildup, enabling use in depleted or underbalanced zones
- Precise selective control of stimulation stages, independent of well pressure profiles
- Eliminates complexity of ball management and dropped-ball sequencing
- Enhanced operational flexibility for complex well trajectories
Compatibility
- Works with standard coiled tubing shifting tools
- Can be integrated with both open-hole and cemented completion architectures
- Fully compatible with Frontier’s Ball-Drop Multi-Stage Sleeve systems for hybrid completions
- Suitable for extended-reach, multilateral, and unconventional well designs
Certifications & Quality Assurance
- Manufactured under strict QC protocols
- API-aligned metallurgy, elastomers, and pressure-testing procedures (where applicable)
