Modelling Low-Salinity Water Flooding as a Tertiary Oil Recovery Technique

Blog Article

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 starts fifteen years after adifom q red 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 plt poultry litter treatment flooding as slug injection.From the three cases presented, oil recovery efficiency, field oil production rate, and field water cut were observed.

Increased percentages of 22.66%, 35.12%, and 26.

77% were observed in the three cases, respectively.
