Abstract: A method for controlling drilling fluid properties includes receiving one or more measurements representing a drilling efficiency of a drilling rig including a drill bit deployed into a well. A drilling rig circulates a drilling fluid in the well. The method includes determining that the one or more measurements are lower than expected, determining that a property of a subterranean formation in which drill bit is positioned has changed based on one or more measurements, and in response to determining that the subterranean formation has changed, automatically generating a drilling fluid adjustment plan based at least in part on one or more of a drilling fluid inhibition factor or a drilling fluid stability factor.
