Using Raman shift and FT-IR spectra as quality indices of oil bit PDC cutters

Rafid K. Abbas Kanaan Mohammad Musa

Nowadays many of oil and gas wells are drilled extensively by Polycrystalline Diamond Compact (PDC) drill bits. Various companies are manufacturing PDC cutters according to their usage. All of these companies concentrate their products of PDC cutters to be well resisting for abrasive wear. The wear of PDC inserts leads to money loss as well as delays the drilling procedures causing unexpected dilemmas. Therefore, it is crucially significant to evaluate the quality of the PDC cutters based on their resistance against abrasive wear.
