An evaluation of the Tongonan geothermal reservoir was conducted to improve the power recovery through reservoir and process optimization. The performance of the existing production wells was reviewed and the response of the field based on the anticipated production levels was simulated at various operating conditions. The results indicate that the Tongonan geothermal reservoir can be exploited at a high pressure operating condition with substantial improvement in the field capacity. The authors calculate that the Upper Mahiao and the Malitbog sectors of the Tongonan field are capable of generating 395 MWe at 1.0 MPa abs., on top of the existing 112.5 MWe plant, compared with 275 MWe if the field is operated at 0.6 MPa abs. The total capacity for the proposed Leyte A 640 MWe expansion can be generated from these sectors with the additional power to be tapped from Mahanagdong and Alto Peak sectors.
