Dual-connection fracturing fluid delivery technology

monoflex frac technology

Reduce safety risks, rig-up time, and NPT

MonoFlex™ dual-connection fracturing fluid delivery technology speeds up multiwell pad rig-up, reduces NPT, and limits HSE risks with a flexible, erosion-resistant conduit that can be used on any part of the fracturing fluid delivery system.

MonoFlex technology has been proven in field applications since 2017. By simplifying flow paths and minimizing the number of connections and flowlines, the technology has streamlined operations and optimized proppant and fracturing fluid delivery in more than 2,000 wells across North America.

Available to oil and gas operators and service companies, the technology has been used to connect

  • frac pumps with the missile system
  • missile trailer with the instrumentation skid
  • frac trees with zipper manifolds and trunk lines.

By eliminating sharp turns and multiple flow paths, MonoFlex technology limits friction losses by 2% to 4%, typically reducing hydraulic horsepower requirements while still accommodating flow rates up to 160 bbl/min.

Expedite mobilization by minimizing connections

MonoFlex technology features a robust and flexible high-pressure system with only two connections—a significant reduction compared with the 50+ hammer union connections required per well with conventional treating iron systems. This key technology

  • eliminates the potential to mismatch equipment
  • simplifies pad setup
  • eliminates excess flowlines
  • decreases NPT by reducing the number of possible leak paths
  • reduces operating expenses.

Various bore sizes with 15,000-psi [103.4-MPa] maximum working pressure and temperature range from –40 to 158 degF [–40 to 70 degC].
