Abstract (en)
The flow of a multi-flow liquid phase liquid/gas production fluid from an oil well is boosted by alternately introducing the production fluid into a chamber (5,6) and thereafter expelling it from the chamber by displacement by a liquid (13) which can be pumped by a conventional single phase liquid pump. <IMAGE>
