Petropedia explains Blind Seal Ram
In the event a well blowout occurs and uncontrolled release of oil and/ or gas from the well, it becomes necessary to close the wellbore so as to avoid catastrophes. Blowout Preventers (BOP) are used in oil wells to prevent well blowouts. Rams which are components of ram blowout preventers are available in variable-bores so that a wide range of pipe diameter can get covered for sealing. The blind seal ram is used to close off and seal the well when the well does not contain the drill string and other tubing. It has no opening for the tubing and is blanked off to close the well.
