Abstract
The need for artificial lift to improve the economics of geothermal fluids production for power generation and direct use applications has been recognized for many years. Electrical submersible pumping (ESP) systems have been used successfully in geothermal and other high temperature applications and show significant promise for future applications. This paper briefly describes the ESP system, its use in geothermal wells and the development of ESPs for applications in excess of 220?C. In addition, the paper explores future pumping requirements for new geothermal applications such as Enhanced Geothermal Systems (EGS) and outlines recent and future ESP advances for effective operation in increasing well depths, temperatures, and flow rates.
