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
