Swellable Packer
Product Overview
The Swellable Packer is an adaptable isolation solution engineered for cemented and uncemented multistage liner completions. Using specially formulated elastomers activated by water or oil, it delivers reliable zonal isolation in open hole environments and supports selective fracturing operations.
Key Features
- Available in water-activated and oil-activated elastomer formulations
- Fully customizable elastomer to match wellbore fluid composition
- Standard 6 ft and 8 ft element lengths; extended lengths available upon request
- Variable swell times optimized through elastomer selection
- Maintains full casing ID for unrestricted flow path
- Tensile strength matched to liner to ensure mechanical integrity
Applications & Drilling Scenarios
- Open hole uncemented multistage liner completions
- Zonal isolation across ball-activated frac sleeves
- Cemented and uncemented installations requiring long-term integrity
- Selective fracturing in varied reservoir conditions
Advantages
- Highly customizable elastomer formulation for precise swell response
- Field-proven performance in multistage horizontal completions
- Full casing ID enables unrestricted intervention and production options
- Broad size range supports diverse well architectures
Compatibility
Suitable for liner systems, multistage fracturing tools, and completion accessories across all major casing standards. Compatible with both water-based and oil-based wellbore environments.
Certifications & Quality Assurance
Manufactured under stringent quality control processes aligned with ISO and API standards. Material compliance and traceability available upon request.
