摘要

WITH THE GROWTH of the North American shale plays, it's not surprising that bit companies are aggressively working to meet the challenges of drilling in the these plays, with new designs or enhancements of existing designs for specific applications. Several recent designs include new cutter materials for drilling in abrasive or high-temperature formations. Several also feature eight-bladed designs that incorporate new cutter technology and materials, as well as newer bit body materials to increase durability and performance. One result is lower drilling costs for operators.
