Rate of penetration (rop) optimization advisory system

A computer system for performing a drilling operation of a well in a subterranean formation, comprising:

• a processor;
• and
• a memory coupled to the processor and storing instruction, the instructions, when executed by the processor, comprising functionality for:
• obtaining a plurality of drilling data records each comprising a revolutions per minute (RPM) value, a weight on bit parameter (WOB) value, and a rate of penetration (ROP) value;
• analyzing the plurality of drilling data records to generate a maximum point comprising a maximum ROP value that is based on a predetermined percentile of an ROP distribution of the plurality of drilling data records;
• generating, based on the maximum point and a current point, a recommendation point comprising of a recommended RPM value and a recommended WOB value, wherein the current point comprises a current RPM value, a current WOB value, and a current ROP value of the drilling operation;
• and
• presenting, to a user, the recommendation point to facilitate the drilling operation.
