Product Overview
Our hydraulic retrievable fishing socket is an external gripping overshot designed for retrieving tubular downhole equipment including tubing, drill pipe, sucker rods and other cylindrical objects. The socket features a hydraulic release mechanism that allows controlled release of the caught fish when required, eliminating the need for jarring or mechanical impact to disengage. The spiral or basket grapple inside the socket grips the fish securely when tension is applied. When hydraulic pressure is applied to the release port, the grapple expands, releasing the fish for retrieval or repositioning. Precision machined from high-strength alloy steel with hardened grapple teeth for reliable gripping. Standard thread connections for integration with fishing BHA. Sour service material options available.

Typical Applications
- Recovery of broken coiled tubing, production tubing and pup joint segments
- Fishing of packer outer mandrels, failed mill bodies and external tubular downhole parts
- Fishing operations matched with jarring tools for severely stuck tubular fish
- Circulation assisted fishing to wash away sand packed around target fish
- Sour well fishing intervention under H₂S/CO₂ corrosive downhole conditions
- Salvage of fallen drill pipe segments during workover remediation
- Retrieval of outer surface components of damaged downhole equipment
Advantages Over Conventional Non-Retrievable Overshots
- Independent hydraulic release mechanism enables safe tool retraction when fish cannot be recovered, avoiding expensive secondary fishing work for stuck overshot
- Built-in flow ports allow continuous circulation during fishing to remove sand deposits around fish
- Replaceable slip inserts extend overall tool service life and reduce hardware procurement expense
- Stable gripping performance under repeated jarring impact for heavy stuck fishing scenarios
FAQ
Q: Can the hydraulic release pressure be adjusted for on-site requirements?
A: Yes, we modify internal hydraulic orifice and spring parameters to customize target release pressure for your operation.
Q: Can sour well compatible versions be supplied?
A: We provide NACE MR0175 certified sour service versions with full material test certificates for export clearance.
Q: What catch ranges are available?
A: Standard catch range covers 0.75" to 1.90"; custom ranges are available upon request.
Q: What is the production lead time?
A: Standard in-stock models ship within 3–7 working days; customized fishing sockets take 15–25 working days.
