Rop modeling of rollercone and pdc drill bits

, 2012
Drilling simulation technology has been used extensively to optimize the drilling operation so as to minimize the associated costs and risks. Optimum bit types and designs with corresponding drilling parameters can be recommended for the entire bit runs through simulation studies utilizing rate of penetration (ROP) models.
