US 2025/0084704 A1 · SELF-CONTAINED COMPACT ROTARY STEERABLE SYSTEM

Abstract

A self-sufficient rotary steerable system configured to provide a bottom hole assembly with a build-up rate of at least 25 degrees per 100 feet of drilling distance. The rotary steerable system has a reduced length without the removal or omission of functional components, including a power module, a control module, a communication module, a filter module, a valve module, and/or a pressure regulation module. The build-up rate is defined as a function of a length between a first contact point on a drill bit of the bottom hole assembly and a second contact point at a piston assembly of the rotary steerable system; length between the second contact point and a third contact point at a stabilizer of the rotary steerable system; the drill bit outer diameter; the piston assembly outer diameter; and the stabilizer outer diameter.
