| Abstract | With data form 23 wells we derived the corresponding values of pressure, enthalpy, water saturation, and steam quality for the unperturbed fluids of the reservoir. On this basis we developed a vertical 1D model of the reservoir which accurately reproduces the main observations. The model reveals the existence of a deep, hot, extended aquifer at the abase of the system; that there is no significant recharge from the surface of the field; and that a caprock seal exists over a major part of the reservoir. It also shows that Los Azurfres is an unusual system in which the transition between a liquid dominated and a vapor dominated reservoir is observable. |
