Zipper Manifold

When completing a single well, a significant amount of idle time is imposed on these costly resources. Time spent waiting for an isolation plug to be set, to position and fire perforator guns in the next zone, to retract the wireline and the perforator gun carriers, and to isolate the lubricator from the well—all of these operations contribute to a costly underutilization of the frac crew and equipment. A frac manifold is an arrangement of flow fittings and valves installed downstream of the frac pump output header (often called the “missile”) and upstream of each frac tree being served by it. From the main supply line of the frac manifold, a dedicated frac supply line is installed to the goat head atop each well. Utilizing this arrangement, the manifold is used to quickly isolate wells that have completed a frac cycle and for which intervention (plug and perforate) is now required, and to redirect the flow of frac fluid to a well that is prepared for the next frac cycle. The use of actuated valves improves transition speed and eliminates the need for manual adjustment, reducing safety risk.The use of a frac manifold in this manner is called “zipper” or “zip” fracturing, and it can provide for almost continuous utilization of the frac crew and equipment, from the first treatment at the toe of the first well to the last treatment at the heel of the last well. This represents a substantial improvement to the effective use of the fracturing resources and, thus, to the overall economics of the well.

Features and Benefits

Enhances safety of operations
Streamlined manifold design reduces clutter at well pad. Hydraulic actuated gate valves allow remote operation, removing the opportunity for personnel exposure to potentially pressurized vessels.
Increases number of fracs performed per day
Allows for continuous operation of multiple wells, improving utilization of pumping services
Provides ease of operation
Hydraulic valves allow remote control of manifold valves to direct flow as desired
Decreases number of rig up/rig down cycles
Manifold design allows for control of fluid flow to multiple wells; eliminating the need for rigup and rigdown between frac stages
Decreases pumping downtime
Allows for frac to occur at one well while running wireline services at another well simultaneously
Reduces multiple frac lines
Single inlet for pumping equipment drastically reduces number of flowlines required
