Automated real-time transport ratio calculation

A non-transitory computer-readable medium storing one or more instructions executable by a computer system to perform operations comprising:

• determining, in real-time, values of drilling parameters of a drilling system drilling a wellbore;
• calculating, based on the values of the drilling parameters, a cuttings concentration in an annulus of the wellbore (CCA);
• calculating, based on the calculated CCA and a mud weight (MW) of a drilling fluid, an effective mud weight (MWeff) of the drilling fluid;
• calculating, based on the effective mud weight, a slip velocity of the cuttings;
• calculating, based on the slip velocity, a transport ratio (TR) of the cuttings;
• and
• controlling, based on the transport ratio, a component of the drilling system to adjust at least one of the drilling parameters.

A computer-implemented system, comprising:

• one or more processors;
• and
• a non-transitory computer-readable storage medium coupled to the one or more processors and storing programming instructions for execution by the one or more processors, the programming instructions instructing the one or more processors to perform operations comprising:
• determining, in real-time, values of drilling parameters of a drilling system drilling a wellbore;
• calculating, based on the values of the drilling parameters, a cuttings concentration in an annulus of the wellbore (CCA);
• calculating, based on the calculated CCA and a mud weight (MW) of a drilling fluid, an effective mud weight (MWeff) of the drilling fluid;
• calculating, based on the effective mud weight, a slip velocity of the cuttings;
• calculating, based on the slip velocity, a transport ratio (TR) of the cuttings;
• and
• controlling, based on the transport ratio, a component of the drilling system to adjust at least one of the drilling parameters.
