Processes and apparatus that continuously change the physical state and characteristics of drilling fluids at planned periodic intervals to consistently and correctly compensate for differing geological formation properties, wellbore characteristics, rate of penetration, solids removal efficiency, and other essential factors involved in the drilling process, comprising: initiating a system correction of a Minimum Base Required (“MBR”); and administering a dilutant to a drilling fluid according to the MBR. The system corrections may be performed recursively, adjusting the system's base dilutant and chemical product additions according to MBR. The drilling fluid consistency produced is based upon several drilling-rig specific parameters. Drilling fluid consistency is provided onsite through the use of mathematical software, base fluid, rig software that targets the programmed parameters, and scheduled treatments that are structured for stability according to the minimum amount of base dilutant and required quantity of chemical product to produce consistent drilling fluid properties.
