The Pantera Mechanical Bottom Bailer or PMBB® is a mechanical tool for well intervention with the sole purpose of dumping cement, bridging shots, chemicals, and other materials on top of a solid bottom. Can be conveyed by wireline or slickline as requires no voltage supply.

The PMBB gets activated by tagging a hard surface and displacing a bottom mechanism to immediately expose 4 ports that allows communication between the dump bailers content and the wellbore.

With no breakable parts nor debris from the activation, the tool can be reset on surface for a subsequent run without the need of redressing.
