Abstract
This paper presents a case history of definition of the temperature and pressure distribution in a high temperature geothermal field in Southern Negros, the Philippines. This was achieved through a careful pressure profiles form 21 wells and combination of geological and drilling data. Based on analysis the following flow model of the local natural convection system was derived: up flow near a young volcanic neck; lateral and upward migration to the highest point of the local block faulted structure; partial down flow beneath the volcanic axis; up flow into the drilled depths in two levels along two different faults until convecting water reaches groundwater saturation zone and finally outflow until water reaches ground surface as springs.
