ROTARY STEERABLE SYSTEM WITH OPTIMIZED PISTON EXTENSION
A rotary steerable system including a steering section having at least one piston configured to extend a stroke length radially outward from a default position when activated. A ratio of the stroke length to a steering section diameter is greater than about 0.06. The steering section includes two piston sets. A ratio of a length of the piston to a diameter of the piston is between 1 and 1.4.
