Product Code: WBI PDS 0021
The Flow Release JDC type overshot provides a reliable method of running and retrieving tools with a standard external style fishing neck profile. The tool does not require the use of shear pins or drop balls to activate, requiring only hydraulic pressure.
The overshot can be engaged onto a fishing neck by simply setting down minimal weight to overcome the spring force on the grapple. The tool can be released from the fish by simply setting down weight on the BHA while circulating at a pre-determined flow rate through the tool. Flow through the tools adjustable orifice creates the back pressure required to shift the latch grapple into the release position. The internal spring returns the grapple to the catch position when flow through the tool is stopped. The tool can be functioned as many times as required.
The tool's adjustable orifice is easily changed to adjust the activation flow rate and pressure to suit each application. Flow through the tool can also be used to wash debris from around the fishing neck prior to latching.
Features:
- Hydraulic operation, no shear screws required.
- Flow through capability.
- Can be functioned multiple times.
- High tensile strength for jarring operations.
- Proven, reliable design.
- Variable catch size for each tool.
