Abstract
A method is presented for discharge analysis of two phase geothermal wells. The method is based on using a two phase flow wellbore simulators and the concepts of pivot point and productivity index. Using the method the deliverability curve of geothermal wells can be estimated form two downhole pressure surveys taken during warm-up, and one output measurement obtained when the well has reached stable discharge. The method is demonstrated using data for well 12 in the Svartsengi field in Iceland.
