Releasing Back‑off Spear for Oil & Gas Well Fishing & Back‑off Operation

Releasing Back‑off Spear

The Releasing Back‑off Spear is a specialized well‑service fishing tool designed for downhole fishing, back‑off breakout operations and releasing fish inside wellbore.

  • Simultaneously grips the inner diameter of fish and transmits left‑hand torque during back‑off work
  • Serves as an effective alternative to conventional left‑hand taper taps and die collars
  • Similar in function to back‑off subs, with key advantage that thread make‑up with fish is not required
  • Can engage and catch any section of the fish inner diameter, instead of being limited to existing threads on fish
  • When stuck downhole, the spear can be released conveniently, avoiding secondary downhole sticking accidents
  • Widely applied in oil & gas well fishing operations to retrieve fallen drill pipes, tubing and other tubular fish
