Summary A method has been developed for low-invasion, downhole motor coring in the Arab formation, Arabian Gulf. Motors were used for the first time in the Arab formation to achieve higher bit rotational velocity and higher coring rate for low filtra

Regions of western Canada comprise tough interbedded formations of hard sandstone, siltstone, shale and chert, which create great challenges for directional drilling applications. Historically, using conventional tungsten carbide insert (TCI) rollerc

In several Canadian applications, operators have recognized the potential to replace standard roller cone products with a more viable solution that will drive down costs when drilling straight hole and curved sections. In these high-abrasive applicat

Extensive research and development has produced a new generation of PDC bits, designed to drill harder and more abrasive formations than standard PDC bits, including those with the latest abrasion-resistant cutters. The new-generation PDC bits allow
