The Flow-Release Spear is a device for fishing either:
- Downhole equipment with a damaged internal fishing neck
- Tubular sections lost within the wellbore
To engage the fish, simply set down weight allowing the slip to collapse into the bore. When an overpull is applied, the slips will take hold of the fish.
To release from the fish, simply set down weight and flow through the tool. This creates the differential pressure required to de-support the slip and allow it to collapse and release.
The Flow-Release Spear can be supplied with a complete range of hardened slips for varying internal diameters and a selection of nozzles to vary the activation flow rate are also available.
Standard tool and grapples are listed below but other sizes and grapples are available.
