- W41180403 abstract "Over the years, drillers and operators have placed increasing demands on the drill string. As a results, components of the drill string have become more diverse in application and more durable and reliable in performance. Even today's depressed prices, several $100,000 worth of drill string equipment can be in the hole at one time. The combination of downhole mud motor, MWD tool, and high-performance PDC bit provides the operator and driller with plenty of firepower to drill ahead-but at a hefty price. Numerous laboratory and field studies have been carried out to gain a better understanding of a drill string's performance and how to improve drilling operations. More research efforts in the coming years will be directed toward downhole problems. If penetration rates can be increased, while drilling time and costs reduced, drilling becomes more economical and attractive. This article is a short synopsis of various new technologies affecting today's drill string." @default.
