Multiphase Gathering System (MGS)

The Leistritz Multiphase Gathering System (MGSs) are expandable versions of the MWS, designed to handle production from multiple wells. Individual MGSs handle total flow rates up to 550,000 bpde and differential pressures up to 1400 psi. These systems are fully automated and can be expanded to operate multiple MGSs in parallel for facilities requiring additional flow capacity.

  • Lower overall gathering system pressure, allowing low producing wells to overcome flow line pressure from high producing wells.
  • Reduce the amount of gas lift and/or assist down-hole pumps.
