22 APRIL 2025 WorldWide Drilling Resource® The Bit Guidance System Adapted from Information by Helmerich & Payne, Inc. (H&P) Operators need reliable tools to achieve their drilling objectives in today’s complex and time-sensitive environment. H&P’s Bit Guidance System is one such tool, designed to mitigate the challenges of directional drilling in high-cost, unconventional wells. This proprietary algorithm-driven system considers the total economic impact of directional drilling decisions in real time, ensuring positive outcomes. To demonstrate its effectiveness, H&P conducted a head-to-head comparison of eight wells in the Eagle Ford Basin, in south Texas, using their bit guidance system for four of the holes and drilling without it for the other four holes. The wells were drilled approximately at the same time and within one mile of each other, similar rock formations, well path geometries, drill bit, bottom-hole assembly, and rig equipment. The well using bit guidance had more intricate well geometries and longer lateral feet, which made the task more challenging. To estimate bit location, the system relies on prior actions like sliding and rotating, and then outlines actions for the next 300-1000 feet. Additionally, it continuously monitors the drilling trajectory, projects a forward path to stay within the drilling window, and minimizes high curvature sections. Precise execution of the system instructions is ensured by the Automation Sequencer, while the Survey Management solution addresses uncertainty in relative wellbore positions, which can lead to substantial differences between actual and reported lateral spacing. By incorporating a bit guidance system, wells witnessed notable drilling time reductions, enhanced accuracy, and minimized tortuosity. HDD
