Product Overview
Our hydraulic retrievable GS fishing spear is designed for internal gripping and recovery of tubular downhole equipment including tubing, drill pipe and casing. The spear features expandable slips that engage the internal wall of the fish when tension is applied. A hydraulic release mechanism allows controlled release of the fish without jarring or impact. The GS (Gravel Spacer) design provides a larger internal bore for fluid passage during fishing operations. Precision machined from high-strength alloy steel with hardened slip teeth for reliable engagement. Standard thread connections for integration with fishing BHA. Sour service material options available.

Typical Applications
- Recovery of fallen coiled tubing segments and tubing joints
- Fishing of stuck packer mandrels, sliding sleeve inner barrels
- Salvage of broken production tubing and tail pipe sections
- Deviated / horizontal well tubular fishing paired with jarring tools
- Sour well fishing intervention under hydrogen sulfide corrosive conditions
- Circulation-assisted fishing with simultaneous sand washing around fish
- Retrieval of inner components of damaged downhole tools
Advantages Over Non-Retrievable Fishing Spears
- Independent hydraulic release mechanism allows safe tool withdrawal if fish cannot be pulled free, eliminating permanent tool loss risk
- Built-in flow ports support continuous circulation to clear sand deposits around fish during fishing
- Spring-slip structure adapts to minor inner diameter variation of target tubular fish
- Hardened replaceable slip inserts cut long-term operating cost
- Compatible with accelerators & hydraulic jars to handle heavy stuck fishing scenarios
FAQ
Q: Can I adjust the hydraulic release pressure for site requirements?
A: Yes, we modify internal orifice and spring parameters to set your required release pressure.
Q: Is sour service version available for high-sulfur wells?
A: NACE MR0175 certified sour service models are supplied with complete material test certificates for export customs clearance.
Q: What internal catch ranges are available?
A: Standard models cover 0.75" to 1.90" ID catch range. Custom ranges available upon request.
Q: What is the production lead time?
A: Standard in-stock models ship within 3–7 working days; customized fishing spears take 15–25 working days based on order quantity.
