Operational drilling parameters optimization is necessary for increase drilling efficiency in complex geological drilling process. There are four key objectives to evaluate the drilling efficiency, including drilling cost, rate of penetration (ROP), drill bit life, and drill bit's specific energy. In this paper, we proposed a multi-objective optimization method to …PROS: Sonic drilling can provide a continuous core sample of in situ materials (unconsolidated and consolidated) with limited refusal, which is important when trying to understand the finer details of the underlying geology. It is an extremely versatile and fast method of drilling usable in nearly all lithologies and fill materials. Serkan Kahraman adlı üyenin tam profilini görüntüleyin.
