Caged-Ball Frac Plug Configuration

Help With This Product

The ProDrill Express Series caged-ball frac plug utilizes a simple ball/cage adapter that houses a ¾-in. brass ball in the upper ID of the plug. When zonal pressure is greater from below the plug, the ball cage allows the lower and upper zones to communicate. When zonal pressure is greater from above, the ball seats; thus, isolating the zones.
