  • Pulsation dampener apparatus and method
    Patent number: 6874540
    Abstract: A pulsation dampener apparatus and method for dampening pulses within a fluid flow line during well drilling operations. The pulsation dampener apparatus comprises a cylindrical body having an annular chamber, a piston slidably disposed within the annular chamber, a gas column within the annular chamber and a means of communicating pulses from the fluid flow line to the piston. The piston is operated against the gas column to dampen the pulses within the fluid flow line.

  • Electro-mechanical drilling jar
    Patent number: 6729419
    Abstract: A drilling jar comprising a mandrel with a shoulder extending radially outward. The shoulder defines at least one openable and closeable orifice therethrough. An outer housing is slidably disposed about the mandrel to define an upper chamber above the shoulder and a lower chamber below the shoulder. The jar also comprises a magnetorestriction material that responds to a predetermined pressure in the upper chamber to open at least one orifice in the shoulder to allow rapid pressure communication between the upper and lower chambers.
