A MEDAS has been installed in four production wells in the Mahanagdong production sector of the Leyte Geothermal Production Field located in the island of Leyte, central Philippines. This field is chosen because: 1) it is the largest geothermal field in the Philippines with five separate power plants with total installed capacity of about 700 MW, and 2) the area is bisected by the Philippine Fault, a major left- lateral transcurrent fault similar to the San Andreas fault. The System is installed in the „Greater Tongonan Geothermal field “ in Leyte on the MG5 pad with the bore holes MG 18 D ( high gas) ( CAN 14 ) MG19D ( Calcit in flow ) ( CAN 12 ) MG 23D ( cold water in flow) ( CAN 13 ) MG32D ( high gas ) ^ ( CAN 15 ) www.sarad.de
