Abstract
(English)
Alfina geothermal field is made up of a gas-cap (CO2) overlying 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. During the first production tests the analysis of pressure and water-levels showed that the gas-water interface had risen. This was later confirmed when a gas-producing well began carrying water. This paper attempts to explain field behaviour by means of simple calculations and assuming an idealized geological structure. This study gives an estimation of the average porosity and initial gas in place.
