Gilman A Hill: Down hole, hydrodynamic well control, blowout prevention. Sheridan Ross PC, April 9, 2002: US06367566 (76 worldwide citation)

The system and method of the present invention permits control of down hole fluid pressures during under balanced drilling, tripping of the drill string, and well completion to substantially avoid “killing” of the well and thereby damaging the producing formations in the well bore. The system and me ...
