Crude oil and water flow from several types of soil analysis using numerical modeling.

Finite element model has been carried out to simulate the vertical flow and horizontal flow of water and crude oil on several types of soil. Eight models were constructed with a cross-section length of 1000 mm and a height of 350 mm for different types of soil on one layer like (sand, clay, silt, silty sand, and silty clay), and two layers of soil like sand (50%) and clay (50%), sand (50%) and silt (50%), and clay (50%) and silt (50%). Steady-state analysis was applied, and the simulation results obtained that the water discharge quantity (m³/sec) is less than the crude oil discharge quantity on all the scenarios on the steady start analysis, like for the vertical flow simulation, found the highest value is 1.1% for the silty sand soil and the lowest is 0.2% for the clay soil model. And in the horizontal flow simulation, found the highest value is 1.71% for the sandy soil model and the lowest is 0.1% for the clay soil, while there is no change in the flux quantity for the sand-clay and sand-silt soil models.
