1. A method for optimizing drilling performance of a drilling operation, the method comprising:
advancing a drill bit during the drilling operation of a well based on a plurality of drilling parameters comprising mud weight of drilling fluid, volume output and stroke per minute of a mud pump circulating the drilling fluid downhole through the drill bit to return cuttings to the Earth surface, rate of penetration, revolutions per minute, and weight on bit;
acquiring, using a plurality of sensors disposed throughout a rig of the well, sensor measurement data related to circulation of the drilling fluid and comprising a drilling fluid flow rate and a cutting concentration of the cuttings;
generating, using a drilling hydraulics model based on at least the sensor measurement data of the circulation of drilling fluid, modeled rig and bit hydraulics data comprising an equivalent mud weight, a pressure drop at the drill bit, and a bit hydraulic horsepower per square inch (BHSI), wherein the equivalent mud weight is calculated based on the mud weight and the cutting concentration, wherein the pressure drop at the drill bit is calculated based at least on multiplying the equivalent mud weight by the drilling fluid flow rate;
continuously updating the equivalent mud weight and the pressure drop at the drill bit based on the drilling fluid flow rate and the cutting concentration that are continuously changing in real-time while advancing the drill bit during the drilling operation;
computing, in real-time, the BHSI using the drilling fluid flow rate and the pressure drop at the drill bit; and
adjusting, during the drilling operation and using the real-time computed BHSI, one or more values of the mud weight, the volume output and stroke per minute of the mud pump, the rate of penetration, the revolutions per minute, and the weight on bit to optimize drilling fluid hydraulics to circulate the cuttings to the Earth surface.
