- •
Two natural sandstone cores and one artificial sandstone core were studied.
- •
Effects of quartz content on residual water saturations were identified.
- •
Long time drainage experiments were investigated in detail.
- •
The drainage process is divided into three stages based on the experiments.
- •
A capillary model is used to interpret the mechanisms characterizing the drainage.
