This paper concentrates on ROP estimation using bit type and its properties, mud type and mud viscosity, formation parameters such as rock strength, formation drillability, and formation abrasiveness, and some critical drilling equipment operational parameters such as pump pressure, WOB, and rotary speed based on the previous drilled wells data with the ELM and USA model.
