  165 mm and 121 mm oscillators

  Enable a significant boost in the drilling speed by reducing the drill string friction force during sliding. Enable a better weight transfer to the bit without losses on wellbore walls, improving bit controllability.

  Double-acting HJDA hydraulic drilling jars OD 4 ¼”/105 mm, 4 ¾”/121 mm, 6 ½”165 mm, 8”/203 mm & 9 ½”/241 mm

  Double-acting hydraulic drilling jars are used in high-inclination, high-friction wells and withstand standard bottom-hole temperatures 250°F (120°C). The jar can in addition be dressed with seals effective to 400°F (200°C) for high borehole environments.

• Borehole Enlargement Services

  Hydraulic borehole enlargers are manufactured from the highest-strength and grade of alloy steel material (SAE 5140 or similar grades).

  Hydraulic and fixed diameter hole enlargement equipment diameters:

  • From 4 1/2"(114 mm) up to 72"OD (1828.8 mm)

  Borehole enlargers are made from a high-grade alloy in accordance with NS-1TM standards (Quality Control Requirements for New and Refurbished Drilling Equipment, Completion Equipment).

  Reamers designed in cooperation with the experts using the global complex drilling experience.

• Sidetracking Solutions

  Whipstock systems with hydraulic retrievable or permanent anchor/packer and mechanical set & open-hole sidetracking systems

  Whipstock systems with hydraulic or mechanical set anchor allow milling windows in a cased hole for sidetracking.

  Hydraulically set or Mechanical set whipstocks are used to mill a window in a cased hole or set against a cement plug/fish or false bottom (bridge plug) and sidetrack wells with the inclination up to 90°.
