Downhole trajectory automation for rotary-steerable-system (RSS) tools has achieved Level 3 automation, enabling drilling-curve profiles from 0° inclination. Case studies demonstrate the benefits of downhole automation, such as increased rate of penetration (ROP), consistency of delivered dogleg severity (DLS), and reduced surface interactions. Downhole automation minimizes dependencies on variations of formation type, drilling parameters, and directional drillers’ experience levels and delivers a faster operation with a smoother trajectory closer to the well plan, reducing collision risks and easing completion operations while contributing significantly to global sustainability goals.
Advancement of Downhole Automation
Downhole automation was launched with the invention of RSS tools in the late 1990s. Before that, wells were drilled with either pendulum assemblies or mud motors.
