文摘

We have developed a two-dimensional model for LSWI in sandstone formation. The model is based on two different approaches, linear and multi-ion exchange. Capillary pressure concept has also been taken into account in the calculations. The developed model successfully matched the experimental data. The application range for each method was addressed based on each approach's matching quality history.
