Multiphase Wellhead System (MWS)

Applications

  • Boost production from declining wells to buck pressure in the gathering system.
  • Assist existing artificial lift systems by lowering bottom hole pressure and raising the liquid level in the well.

The Leistritz Multiphase Wellhead System (MWS) is a proven and economical method to assist artificial lift systems to accelerate production by lowering wellhead pressure and bottom-hole pressure to allow ESPs and plungers to operate above the bubble point for uninterrupted plateau production. MWSs handle total flow rates up to 100,000 bpde and differential pressures up to 500 psi. These fully automated systems have a small footprint and together with multiphase well testing will significantly reduce flaring, local separation facilities and stock tanks to allow operators to take advantage of more cost-effective centralized process facilities.
