Monoline flanged-connection fracturing fluid delivery technology presents a safer, faster, cleaner alternative to conventional frac iron on multiwell pads, creating a paradigm shift in the way proppant and fracturing fluid are delivered from the pump spread to the wellbore. It is faster to mobilize and increases fracturing uptime while requiring fewer technicians on location. It simplifies the rig-up procedure by arriving on location preassembled; installation time is reduced by more than 60%.
Monoline technology eliminates the potential to mismatch equipment, simplifies hookup, eliminates multiple flowlines, and reduces the number of connections or potential leak paths by up to 75%, thus decreasing HSE risk (conventional systems have 4–8 lines per well with 8–14 connections per line).
The single-line technology adheres to API 6A standards and comprises straight high-pressure pipe segments, 90° elbows, and swivel flanges that are bolted together. Replacing multiple hammer unions by far fewer, measurably torqued flanged connections with metal sealing gaskets promotes a higher level of system integrity, safety, and reliability and lower NPT. The technology enables the full three degrees of freedom needed to accommodate alignment between the frac tree and frac manifold.
In summary, Monoline technology offers a larger diameter for increased flow rate, mitigating erosive fluid velocities; a streamlined design to facilitate installation and reduce the bends in the flow path; and a safer connection that reduces failure points. It is rigged up outside the time-critical fracturing operation and further savings are generated through avoidance of costs related to inspection, maintenance, and spare parts.
