Blow Out Preventer
The Blowout Preventer is comprised of four main components, stacked one upon another. They are the annular preventer, blind ram, blind shear ram, and the pipe ram. There can be many different configurations, sizes and pressure ratings, dependent on well design, formation pressures, and areas of use.
A blowout preventer (BOP) shuts off the valve leading underneath the machinery to stop any liquid from surfacing in a dangerous explosion, or a kick. A level of containment must be maintained when working with the mud and substances that could cause breaks in the flow of extraction.
