Special Borehole Flow Regulator for Gas-lift Wells

Abstract

Offshore gas conditioning and its controlled injection to gas-lift wells is difficult and process-critical. On the other hand, maintaining the bottomhole pressure in gas-lift wells is an important technological issue. The article is devoted to the development of a special borehole installation - flow regulator that controls the supply (injection) of gas to the gas-lift well and that ensures the bottomhole pressure in the well is maintained at a provided value.
