Stinger Disconnect Tool

Expro's Stinger Disconnect Tool improves cement plug quality in permanent well abandonments to mitigate the need for costly and hazardous remedial efforts. The sub allows a cement plug to be placed in a sidetrack or plug and abandonment (P&A) operation without the need to retrieve the stinger assembly for improved reliability and rig time savings. The Stinger Disconnect Tool has the highest tensile – holding capacity and rotational capacity currently on the market while providing the ability to disconnect from the drill pipe and leave the stinger assembly downhole to prevent the disruption and potential contamination of the cement plug after displacement.
