The purpose of the present study was to explore the effect of drill bit selection parameters on enhanced oil and gas recovery fin Iranian oil and gas fields. In this study, many methods and parameters were discussed. These parameters are practically tested on many wells in southwestern field of Iran. Out of common drill bit selection methods, length unit drilling cost is the most popular one owing to the direct investigation of economic parameters related to the performance of the drill bit. However, previous studies conducted in one of the southern gas fields of Iran showed that this method’s results do not yield the optimal drill selection and geology since it fails to evaluate drill bits used in various drilling conditions. To address this problem, some methods have been introduced as complementary of this method which allow comparing various drill bits. In the present work, it was illustrated that using geo-mechanical factors are ideal complements for the method of length unit drilling cost in Iran.
