Abstract
An apparatus and method that form closed-loop system(s) between a downhole system that includes an RSS and a surface control system, to improve stability and performance assurance of the RSS. The apparatus and method account for the actual downhole conditions experienced by the RSS, the actual positioning of the RSS, and historical performance of the surface systems such as the mud pump system, the rotary drive system, and the draw works. These closed-loop systems generate and optimize parameters or target outputs, instructions to surface systems, and instructions for the RSS itself.
