between the tubing and casing strings, which allows pressure to build as the fuid heats up during production opera- tions. SCP is pressure that continues to build, even after being bled off at the sur-

Drilling face. The packer’s V0-rated seal prevents pressure from traveling to upper casing strings, which provides an additional level of safety assurance, particularly for those wells where bleed-off at the well- head is not possible.

Fundamental components

The packer system comprises three design features. First, it has a solid-body mandrel with no fow paths through the body, to maintain pressure integrity and eliminate the potential for hydrocarbon communication between the casing and
