Zipper manifold

A zipper manifold is a large valve arrangement used in multi-well fracturing operations (zipper fracs). It connects the high-pressure pumping fleet to multiple wellheads simultaneously.

This setup allows the frac crew to pump into one well while the wireline crew is perforating the adjacent well. By isolating and swapping between wells instantly using the manifold valves, Non-Productive Time (NPT) is virtually eliminated, significantly increasing the efficiency of completion operations.
