JIWAFlow is a cloud computing system-based wellbore modeling application developed by PT AILIMA, it is used to analyze the effect of heat loss that may occur in wellbore on the productivity of the geothermal well. The author has made a simulation by inputting the required data that is consists of Well Trajectory Data, Casing Design, Feedzone Parameter, Operation Conditions, and Auxiliary Heat Loss. This research is based on the data collected from the geothermal Well Y, the simulation of two-phase flow in wellbore carried out after determining the main task (production: full curve), pressure drop correlation method used (Homonegeous), and approach method according to the type of data available (deterministic) in the simulator. The simulation output consists of the Wellbore Profile and Output Curve, where the output of simulation results is generated into the table and visualized through an analysis curve. The simulation was carried out four times with different flowing time parameters (during the completion test) to see the effect of heat loss on productivity. Firstly, there is no heat loss effect as the baseline scenario, secondly with flowing time of 8 hours, then for three days, and finally in 1 week. After four simulations, the data were collected; Massflow vs. Wellhead Pressure results in the output curve table were compared to see and analyze the presence and how significant the effect of heat loss on productivity in wellbore geothermal field Well Y.
