Completion Seals

Completion Seals

This article describe the categories and types of seals used for completion equipment.

2 categories of seals:

  • static seals where the sealing surfaces do not move relative to one another,
  • dynamic seals where the sealing surfaces do move relative to one another.

3 types of seals:

  • polymeric or resilient seals. Which are either elastomeric (natural or synthetic rubbers) or plastomeric e.g. Teflon.
  • metal-to-metal seals.
  • metal encapsulated polymeric seals (combination of the first two types).
