The behavior of analog mudrock interfaces was examined at the micrometer scale under various confinements and shear rates in room-dry, water-immersed and guar-gum solution states. The data indicated that the presence of water at the interfaces resulted in a continuous reduction of the friction in comparison to the dry state due to a predominant effect of abrasion, whereas no clear influence on the friction was observed in the shearing cycles involving guar-gum solution. The addition of guar-gum solution had a more notable softening effect which was presented by a larger percentage of reduction in the initial tangential stiffness.
