Well AH-4bi, at the Ahuachapan Geothermal Field is planned to be drilled on the same pad as the former AH-4. A simulation study was carried out for two casing dameters 13 5/8 and 9 5/8î in order to estimate its production and to know its economic feasibility. The simulation results indcate a high probability of production in the range of 7 Mwe, equivalent to 120 kg/s total mass flow rate, 1250 Idkg at 6 bar-a for the new well AH-4b;B . Well AH- 17 is good producer, during 199 1 after ten years of production, the well was shut-in due to silica scaling problems. A wellbore simulation was carried out in order to predct the new production condtions after the work-over, mainly to estimate the water flow rate in order to reduce the silica scaling. The results indcate a very low water flow rate. The match between the simulated and measured production curves after the work-over was successful. The well AH-18 is located at the southern part of the actual bore field. CEL is planning to expand the borefield at this area and it is neccessary to estimate the possible production condtions at that zone. The results indicate a high probabilty of production at that area. The power potential is estimated at 3.5 Mwe per well at WHP 6 bar-a and the wells will not require induction.
