  • Installing a tubular string through a blowout preventer
    Patent number: 10900310
    Abstract: A tubular string is cut using a severing system deployed from the rig floor inserted through the BOP into the tubular string and landed in a fit-for-purpose wellhead. The cutting operation forms an excess tubular string and a remaining tubular string. Once cut, the excess tubular string is removed through the BOP. The system and its use eliminates the need to perform a cutting operation at the wellhead by personnel under the rig floor and the need for removal of the BOP thus reducing cost, saving time, and eliminating the inherent risk attendant with these operations.
