The reservoir simulation has been studies to consider waterflooding plan
development. The computer software named “ECLIPSE”; it is used to be tool for
operating. The reservoir model is constructed as hypothetical model. Some data from
U-Thong field, which is in Suphan-Buri Basin, is used for reservoir simulator.
Different flooding scenarios are simulated in order to consider the most optimum
flooding scenario for Suphan-buri Basin.
