  Fig. 14 shows a further depiction of fluid wettability. The two images on the left describe an oil-wet surface and the two images on the right describe a gas-wet surface. The oil-wet surface shows that the oil is absorbing into the surface and is bound while the gas flows on through the rock. The gas-wet surface shows the gas absorbing into the surface while the oil shows absorption resistance.

左がoil-wet surface、右がgas-wet surface。

• gas-wet surfaceを見ると、ガスは表面に馴染んでいるが、オイルはabsorption resistanceを示していることがわかる。
