THD Mechanical Service Packer

DESCRIPTION:

The THD Mechanical Service Packer is designed for general purpose high pressure service work. The THD uses keyed internal connections, allowing transmission of high torque through the packer facilitating rotation of the drill string in high angle holes. The hydraulically operated upper hold-down buttons anchor the packer with differential pressures from below. The packer has carbide trim buttons and slips for high strength casing and longer service life.

Features and Benefits:

  • Heavy-duty mandrel supports high hang-off weights
  • Carbide trim on buttons, slips and drag blocks for hard casing and long field life
  • Quarter-turn set, straight pickup unset
  • Integral internal bypass for high circulation rates
  • Optional extra long top and bottom connections for ease in handling
  • Optional tool joint connections
General Applications:
  • Testing and treating operations
  • Drill stem and production testing
  • Squeeze cementing
  • Storm packer applications
