Deductions of the Character of Steam-Water Wells from the Shape of the Output Curve

Abstract

The output curve of a borehole should tell us much about its character, and the speculations presented here suggest that an early quantitative estimate can be made of the permeability of the rock formation supplying the well, together with its water temperature and hence the discharge enthalpy. Other derived factors are whether the fluid is high in non-condensible gas and i f there is more than one permeable formation tapped by the well; these deductions are based on changes in wellhead pressure which occur after the is closed.
