A review on the wear of oil drill bits (conventional and the state of the art approaches for wear reduction and quantification)

We report a literature survey of the old and current methods of wear quantification in terms of drilling parameters and mechanical properties of the minerals forming the drill bits, and means of increasing the efficiency of oil and gas drill bits. Empirical wear models, as well as wear prediction techniques while drilling are discussed along with the simulation wear models using Finite Element Analysis (FEA) and the Discrete Element Method (DEM).
