Dump bailers are primarily used to place cement (or sand, if preferred) onto pre-existing bridge plugs. Applying cement over a bridge plug allows for a greater pressure differential across it, and the cement can also be used to seal off unwanted water-producing perforations. Titan dump bailers feature a gravity-activated system. This simple and effective design is the most widely used in the industry. Cement is poured into the dump bailer, and a glass rupture disc at the bottom of the chamber holds the cement in place. Once positioned above the bridge plug, the glass disc is broken, allowing the cement to fall freely under gravity onto the plug. Heavy-duty top section windows are available for additional support, especially for long dump bailer toolstrings at the filler window, the weakest part of the string. Titan offers two types of activation systems: one uses a small blasting cap placed on top of the glass rupture disc, which can be triggered as needed. The other uses a mechanical striker pin, which, upon impact with the bridge plug, strikes the glass disc, causing it to rupture.
