REASSESSING ARTIFICIAL LIFT WITH EVOLVING TECHNOLOGY

摘要

TECHNOLOGIES TO SUPPORT artificial lift continue to evolve and find their way into Africa's upstream sector. Typically that has meant the use of a mechanical device inside the well, such as an electrical submersible pumping (ESP) or velocity string, or by injecting gas into a well. Other new technologies continue to push for solutions, such as the continuous belt transportation method, which uses an oil absorbing belt to extract from marginal wells.
