In this project, low-salinity water flooding has been modeled on ECLIPSE black oil simulator in three cases for a total field production life of twenty-five years.In the first case, low-salinity water flooding click here starts fifteen years after secondary water flooding.For the second case, low-salinity water flooding starts five years after secondary water flooding and runs till the end of the field production life.For the third case, low-salinity water flooding starts five years after secondary water flooding, but low-salinity water flooding is injected in measured pore volumes for a short period of time; then, high-salinity water flooding was resumed till the end of the field production life.This was done to measure the effect of low-salinity water flooding as slug injection.
From the three cases presented, oil recovery efficiency, field oil production click here rate, and field water cut were observed.Increased percentages of 22.66%, 35.12%, and 26.77% were observed in the three cases, respectively.
