| Abstract | The Northern Negros geothermal field is located in Negros Occidental province, Philippines. The field has an exploitable resource area of 6 - 9 km2 with a most probable mean reserve estimate of 42 MWe for 25 years. Production wells, sited just outside the Mt. Canlaon National Park, will initially supply the high-pressure and low-pressure steam of the 49.37 MWe dual-flash turbine power plant. An Energy Support Zone inside the national park was set aside for the additional siting of make-up production wells. The power plant is set to be commissioned in early 2007. A two-dimensional numerical model for the Northern Negros field was constructed to determine the long term sustainability of the present production area and to project the drilling of make-up wells at the Energy Support Zone. Prediction modeling suggests that the five make-up wells may be drilled at the present production area for the first 13 years of field operation. Additional three make-up wells may have to be drilled inside the buffer zone to have a sustainable steam supply for the remainder of the 25-year operating period. |
