Review of the Development of Rotary Steerable Systems

Abstract

The rotary steerable system is essential for the development of unconventional oil and gas in China, and remains the core of the current oil drilling technology development. This paper outlines the research and development history, classification, development status of the rotary steerable system, and summarizes the advantages and disadvantages of different systems. Moreover, the prospects of the intelligent RSS technology is explored, and the outlook for the future development of the steerable drilling technology is presented.

Rotary steerable systems: mathematical modeling and their case study

“…There are a number of other published models targeting rotary steerable systems. A recently published paper Wang et al (2020) presents a similar model to the one presented here, admittedly taking into account additional effects, such as leverage effect, that method presented here does not take into account. However, the method presented here is presented with full well drilling simulation, while paper Wang et al (2020) focuses purely on analyzing forces, and not a dynamic system.…”
