Correlations between steam saturation, fluid composition and well decline in vapor-dominated reservoirs
Journal Article

· Geothermics; (United States)
A large body of field data from Larderello and other vapor-dominated geothermal reservoir shows striking temporal correlations between (1) decline of well flow rate, (2) gas/steam ratio, (3) chloride concentration, (4) degree of superheat and (5) vapor fraction. The latter is inferred from concentrations of non-condensible gases in samples of well fluid, using chemical phase equilibrium principles. Observed temporal changes in the vapor fraction can be interpreted in terms of a multiple source model.
