The capillary number theory was originally developed by basing the idea off of capillary tube bundles and Darcy's law.<ref name="two">Guo, H., Dou, M., Hanqing, W., Wang, F., Yuanyuan, G., Yu, Z., Li, Y.

Journal of Chemistry, 2017, 1-11. https://dx.doi.org/10.1155/2017/4307368</ref> Darcy's law predicts that residual oil will not be able to be moved until it reaches a critical capillary number. The goal of the experiments driving this theoretical discovery was to determine the saturation movement of this residual oil after it is in contact with water forcing imbibition, which is the expansion of solid when it absorbs water.<ref name="four">Ding, M., & Kantzas, A.
