Smart selective drilling fluid system

A method for selectively supplying drilling mud to a drilling operation, the method comprising:

• measuring, by a plurality of first sensors associated with a first mud pit, a plurality of properties of the drilling mud in the first mud pit;
• measuring, by a plurality of second sensors associated with a second mud pit, the plurality of properties of the drilling mud in the second mud pit;
• receiving, by a control unit operatively coupled to the plurality of first sensors and the plurality of second sensors, measurements from the plurality of first sensors and the plurality of second sensors in real time;
• comparing, by the control unit, measurements from the plurality of first sensors and to the measurements from the plurality of second sensors;
• determining, by the control unit, which of the mud pits comprises drilling mud with the most number of measurements that fall within predetermined threshold values predefined for each of the plurality of properties;
• and
• causing, by the control unit, to operate a first valve associated with the first mud pit or a second valve associated with the second mud pit for selecting drilling mud from the first mud pit or the second mud pit based on the determining step.

A control unit in a drilling fluid system, the control unit configured to:

• receive measurements of a plurality of mud properties from a plurality of first sensors associated with a first mud pit, in real time;
• receive measurements of the plurality of mud properties from a plurality of second sensors associated with a second mud pit, in real time;
• compare measurements from the plurality of first sensors to the measurements from the plurality of second sensors;
• determine which of the mud pits comprises drilling mud with the most number of measurements that fall within predetermined threshold values predefined for each of the plurality of properties;
• and
• cause to operate a first valve associated with the first mud pit or a second valve associated with the second mud pit for selecting drilling mud from the first mud pit or the second mud pit based on the determination.
