Abstract Optimizing the drilling operations depends on an understanding of the interaction between the drilling equipment and the geological formations at any given site and a reasonable estimation of the rate of drilling, given the operational parameters used in drilling. Therefore, it is very important to develop a model for estimation of the drilling rate, using the ground and operational parameters of the drill. These models provide for accurate prediction of achievable rates, time for the well completion and drilling costs as well as optimization of such crucial parameters as weight on the bit and the rotary speed. This paper will address the parameters affecting oil well drilling and uses the information from 50 oil wells in Ahwaz oil field to offer empirical equations for estimation of the drilling rates in related geological formations.
