<p>The flow of a liquid, such as a production fluid from an oil well, is boosted by allowing the fluid to enter a chamber (5A,B,C), from which it is subsequently displaced by gas supplied from a remote source under high pressure (7), the chamber also being connected to a vent line (9) through which the displacing gas, and any gas released from the production fluid, may be vented. <IMAGE></p> |
