Multiphase Wellhead System (MWS)

Applications

  • Boost declining well pressure to buck pipeline pressure.
  • Reduce the amount of gas lift and/or differential pressure on a down hole pump.

The Leistritz Multiphase Wellhead System (MWS) is a proven and economical method of artificial lift that accelerates production by lowering wellhead pressure and/or boosting discharge pressure to buck pipeline pressure. 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 eliminate flaring, local separation facilities and water storage, allowing operators to take advantage of more cost effective centralized process facilities.
