Bowl Protectors
Bowl Protectors perform the very basic function of protecting the upper bowl sealing areas and load shoulder of a head from the drill bit, drill pipe and downhole tools during drilling or workover operations.
- They are installed in the head by running through the BOP stack using a running tool
- They land on the same load shoulder used by the casing hangers
- The I.D. of the bowl protector needs to allow the drill bit to pass through
- They are normally retained in the head by the Lock Down Screws (LDS) in the upper flange
- Should be pulled regularly to remove any built up mud or sand
- Are inexpensive insurance for protecting the wellhead investment
Test Plugs
After a casing head or spool and Blow Out Preventers, (BOP), have been installed on a well a pressure integrity test for these items must be conducted. In order for the test to take place, a test plug should be set in the casing head or spool
