The characteristics of geothermal fluid can be changed during geothermal production activity. Fluid pressure drop and heat transfer between geothermal fluid and well casing and formation will be occurred when the fluid is produced through the geothermal production well. Pressure drop on the fluid can change the physical properties of fluid. The change of fluid fraction and the heat transfer of the fluid can be influenced by the formation temperature and fluid flow rate, then it can cause the fluid temperature changing and heat loss. Ramey (1962) developed an equation that investigated the heat transfer in an oil well in production and injection operation. Codo et al. (2012) developed this equation for geothermal hot water production. The purpose of this study is to determine the effect of the formation temperature and fluid flow rate on the amount of fluid temperature and heat loss. In this study, an analysis of one of the wells in field X was carried out. Based on static pressure and temperature well data, it is shown that the reservoir temperature is 245.17 ?. The result of the analysis of static pressure and temperature is indicated that the type of geothermal fluid that is produced from the well is estimated as a type of compressed liquid. When the fluid is produced, the fluid pressure and temperature loss will be occurred. The fluid pressure drop of every well depth is determined by homogeneous flow model. The fluid temperature and heat loss are determined in every well segment and different fluid flow rate. The highest fluid temperature loss is occurred by the lowest fluid flow and in the well segment with the highest formation temperature difference. The higher of formation temperature difference in the well segment and the lower of fluid flow rate, the higher of fluid temperature and heat loss.
