Methods of Support for the Steam-Water Well Operation in Self-Discharge Mode

Abstract

The conditions for the stable operation of a steam-water geothermal well are considered based on an analysis of the characteristics reflecting the relationship of bottomhole pressure and the flow rate for the well and the aquifer. These conditions ensure the well operation in a self-discharge mode when the static water level is below the wellhead. The main ways and a brief overview of methods for ensuring the operation of steam-water wells in the self-discharge mode are presented. The factors that contribute to the occurrence of instability are specified, and recommendations are given for ensuring the operation of the steam-water well in the self-discharge mode.
