Varel International launched the IMax series of diamond-impregnated drill bits this week at the 2014 IADC/SPE Drilling Conference in Fort Worth, Texas. The IMax bit targets formations that can’t be cut by shearing or indentation, while the IMax+ bit adds a conventional PDC cutting structure and can be applied in formations where shearing is effective but also requires the cutting action of a diamond-impregnated matrix bit. In this exclusive video, Karl Rose, Field Engineer Manager for Varel, speaks with DC about the new-design bits.
