rotary steering systems

This paper explores the applications, benefits, and value of a high-build-rate rotary-steerable system (HRSS) capable of delivering dogleg severity (DLS) greater than 18°/100 ft.

While rotary-steerable systems (RSSs) dominate the offshore directional-drilling markets, the land-based markets are still dominated by conventional directional-drilling tools. This paper presents a new RSS that is being designed and tested specifically for the onshore markets.

A 100% fully mechanical rotary-steerable tool has been developed specifically for the high-volume drilling market, providing full 3D directional control while under full rotation of the drillstring from surface.

This paper outlines two lesser-known types of torsional dynamics observed while drilling interbedded carbonate formations in the Middle East with the latest generation in point-the-bit rotary-steerable systems (RSSs).
