Abstract

This study was carried out on the distribution of temperature gradients and heat transfer in the Blawan geothermal field, using a temperature sensor to detect the below-ground temperatures to a depth of 2 m with five sensors. Each of these sensors is able to record temperature with an interval of 30 s. The temperature distribution of the legible data indicates that the highest temperature value has been recorded. Reservoir temperature estimation models were obtained at a depth of 2000 m by 194 ◦C. Furthermore, the heat flow rate on slaves 1, 2, 3 and 4 were 192.837, 309.046, 517.916 and 228.533 W/m2, respectively. Based on the results of the heat flow calculation, it was discovered that the greater the temperature gradient value, the higher the rate of heat flow occurring at the drill point.
