Abstract
Simulation of transient flow in geothermal wells is an important reservoir engineering task. Previously, we discussed the development of a wellbore simulator capable of modelling complex transient processes in geothermal wells. However, its applicability was restricted to flows of pure water. This paper discusses the implementation of an air-water equation of state in our transient wellbore simulator. The simulator’s capabilities are demonstrated by modelling two discharge stimulation methods, airlifting and air compression. A case study well is considered with a water level approximately 300 m below the wellhead.
