  • Patent number: 8584758
    Abstract: A process for fracturing a lined well uses a packer assembly in a liner string that provides a cement-free segment and interface with the formation. The device has multiple packers with inflatable elements that are run as an integral assembly. After the liner assembly is positioned, cement is circulated into the assembly and wiped from the interior of the liner string into the annulus. Pressure within the liner string is elevated to initiate time delays for the radial inflation of the packer elements. The inflation radially and axially displaces the cement surrounding the elements before the cement sets. Each packer is subsequently opened to expose the frac ports in the packer directly to the formation for frac operations.

  • Publication number: 20120048619
    Abstract: A drilling agitator tool, system and method facilitates axial movement of a drill string in a well. The tool has a valve assembly that provides pulses of fluid pressure in the drill string. A valve control assembly controls a frequency and pressure amplitude of the pulses induced by the valve assembly. The valve control assembly monitors real-time pressure and vibration levels of the drill string. An agitator assembly reciprocates in response to the pulses of fluid pressure to provide axial movement of the drill string in the well.
