Abstract:

It has been observed that the Deliverability curve equation (Power equation) obtained by means Linearization analysis overestimates production rate at low wellhead pressure; in order to improve the forecasting it has been matched the Power Equation with the Offset Elliptical Equation, in that way the Linearization analysis is a helpful tool for determining the Offset elliptical equation parameters. Synthetic data based on a new super big bore New Zealand geothermal well it has been utilized in order to show this procedure.
