Wellhead Protection Application Profile

The wellhead (Casing Head) is mounted on the surface casing. Each additional casing string and the tubing string are then hung from the wellhead as they are run down the hole. The wellhead also seals off the annular spaces between the strings. Once the well is completed, operating personnel no longer need access to the wellhead. Onshore wellheads are typically located just below ground level, either buried or in cellars.

The purpose of this application profile is to provide an understanding of the possible overpressure hazards that exist at the wellhead, and describe possible solutions. This document is intended to be a guideline and is not applicable to all situations. If you have any questions, or a possible application, please contact Fike Oilfield Tools or our sales representative in your area.
