چکیده:

Water injection is one of the process used in petroleum industry for improved oil recovery and pressure maintenance. The histroy of water injectionis a cheap and useful tool to investigate well injectivities in lack of laboratory experiment during a water injection project. There are many easy-to-usetechniques for monitoring a water injection /waterflooding, e.g. Hall plot and its derivative, WOR, GOR plots, instantainous and cumulativevoidage replacement ratio (VRR), production heterogenity index, scatter plot and etc. This paper tries to evaluate different eccessive water productionmechanisms such as near wellbore water channeling, rapid channeling and water coning and the effect of water injection on oil production of one of the Iranianoilfields using minimum available information of an injection and production well like injection pressure, injection rate, oil production rate, water production rate and the time period of injection by using the mentioned surveillance tools.
