ISM High-Performance Tools for Drilling of Oil and Gas Wells. Review

Abstract

The publications addressing the diamond tools for drilling oil and gas vertical and controlled directional wells are reviewed. The performance of diamond drilling tools of various functionalities is assessed by drilling in soft and medium hard formations. Rock destruction tools of different designs, which are fitted with novel thermally stable and wear-resistant diamond-containing composites, are compared with similar tools of earlier models. The main factors responsible for premature tool wear in medium and hard formations at increased speeds are discussed. Some promising areas in the development and application of diamond drilling tools are identified.
