【 摘 要 】

Interference test simulation is conducted to find out the relationship between active well and observation well in a reservoir system through Bottom hole pressure (BHP) Transient analysis of interference test pressure data was performed using PTA software, while interference test simulation was performed using TOUGH2. The main parameters that become input data for transient pressure analysis are Bottom Hole Pressure and flow rate during interference test. Transient pressure analysis is used to determine the condition of wells, reservoir characteristic and the reservoir boundary conditions during the interference test. The research method are calculation of Bottom Hole Pressure with hydrostatic method, transient pressure analysis and reservoir simulation. The results are an interference indication between the WWA-4 and WWA-6 wells in the simulation model of interference test with the transmissivity value 4.7E3 Darcy-meter and storativity value 23.4 m at aquifer thickness value 100 m.
