underground: wellhead control

 

The drilling of long boreholes into the ground always carries the potential, or goal, of encountering gas and/or water at high pressures. Therefore, maintaining absolute control during and after drilling at the wellhead of the gas and or water pressures and flows is a necessary requirement to eliminate this hazard. Target’s specially designed wellhead control system has proven its unfailing ability to
meet this safety need.

  • Collarpipes and wellhead control installed at the start of every borehole
  • Permits fast ansd safe shut-in of borehole during drilling
  • Seals both gas and water to 500 psi
  • BOP can be pumped up to seal around drill rods, and still permit the rods to move in or out
