About
The Casing packers are used to isolate the intermediary string
Spider technology uses a proprietary system which combines expandable steel Ring with an elastomer Element to guarantee an effective annular seal. It also ensures a robust and permanent annulus barrier.
The SPIDER annular casing packer can be set:
• As a primary barrier for non-cemented applications
• Packers enhance cementing operations to guarantee a perfect annular integrity.
• As a secondary barrier for compliance with regulatory authorities requiring multiple annular barriers as part of the overall wellbore architecture design
• For long-term annulus zonal isolation requirements
