Alfina geothermal field is made up of a gas - cap overying an almost closed aquifer. The wells drilled in the highest part of the reservoir produce gas while the others either produce hot water or are sterile. This paper attempts to explain field behaviour by means of simple claculations and assuming an idealized geological structure. This study give and estimation of the average porosity and initial gas in place.
