SYSTEM FOR ENHANCING FLUID FLOW IN A WELL

摘要

A system for enhancing fluid flow into and through a hydrocarbon fluid production well (1) comprising a series of flow boosters (4), such as electrically or hydraulically driven moineau-type pumps or centrifugal pumps or turbines, for controlling and/or boosting fluid flow from various regions of a drainhole section of the well into a production tubing (2) within the well.
