Annular BOPs

Seal around pipe, tools or an open hole with a single packing unit.

Overview

An annular blowout preventer closes a reinforced elastomer packing unit around whatever is in the bore: drill pipe, tool joints, casing, wireline or nothing at all. It is normally the first preventer closed when a kick is detected.

Annular preventers also allow controlled stripping of pipe through the closed element, which makes them central to well control procedures.

Key Features

  • Seals on a wide range of pipe sizes and shapes
  • Stripping capability under pressure
  • Replaceable packing units
  • Hydraulic operation with documented closing pressures

Applications

  • Surface BOP stacks on land rigs and jack-ups
  • Workover and completion operations
  • Stripping operations
