The effect of different percentages of crude oil pollution on soil geotechnical properties is shown. The results show that the moisture content required to achieve maximum dry density had decreased when the oil content increased in the contaminated soil, as well as the liquidity and specific gravity for both sandy and gypseous soils. The crude oil has a significant effect on the internal friction of the sandy soil with respect to increasing the crude oil percentages, while it increases the cohesion of the sand. The consolidation, compression, and swelling indices were increased when the soil is soaked in oil, while the void ratio and hydraulic conductivity were reduced.
