Dump Bailer

The DTI Dump Bailer is designed to dump cement, acid or other fluid onto a solid footing or obstruction in the well. The bottom shoe incorporates a one way filler valve so that pressurized barrel filling can be carried out safely from the bottom end of the bailer. This is especially useful when long length extension barrels are used. Dumping occurs by downward jarring, which shears a pin and opens a flow path through ports in the bottom sub. Barrel lengths are standard 5ft and extension barrels are available.
