Discharging the fluid from the bit nozzles is done with high pressure which assists to break the rocks. Different parameters affect the bit selection and design for each drilling formation, but the most important one is drillability that depends on hardness of the formation. In this paper, the design of continuous gauge near-bit stabilizer and a novel drill bit design was evaluated by optimizing the hydraulics and gauge geometry. It was found that the design is appropriate for the Aghajari and Mishan formations as the drilling efficiency could be increased. Moreover, some problems of drilling in this formation such as bit balling and high wearing were largely reduced by the presented model.   UR - https://jchpe.ut.ac.ir/article_1891.html L1 - https://jchpe.ut.ac.ir/article_1891_56656c8b71a2d9758059a1e729e76baa.pdf ER -
