Operator demands for high inclination and Dogleg Severity (DLS) in these diameters heighten complexities. Key challenges involve achieving desired angles and DLS in unconsolidated formations, overcoming gravity forces at over 50\u00b0 inclination, and managing vibrations causing equipment failures in formations with interfacial severity. Deploying RSS with an autonomous drilling platform ensures efficient, and accurate wellbore delivery on the Norwegian continental shelf (NCS).<\/jats:p>\n               <jats:p>To handle downhole data and multiple wells efficiently, a Data Lake Approach was adopted. This involved leveraging a corporate Data Lake to amalgamate databases from diverse datasets into a unified model, simplifying data visualization in Business Intelligence (BI) tools. Automation of the data collection saves time for drilling analysis, eliminates the need for manual data collection, preparation. Furthermore, the correct automation setup and utilization of a web-based dashboard address a key customer objective - increasing Rate of Penetration (ROP) by automatically adjusting the rotary steerable system's steering force and toolface to match the demanded DLS and wellpath.<\/jats:p>\n               <jats:p>Ten drilling runs, utilizing hybrid bits with Push-the-Bit RSS as well as Tungsten Carbide Insert (TCI), and Milled Tooth roller cone bits, were analyzed. All bit types demonstrated excellent performance in vibrations and steering, outperforming PDC (Polycrystalline Diamond Compact) bits. Similar issues were noted with Point-the-Bit RSS. Recent runs with hybrid bits yielded optimal results: low Stick-Slip and Whirl vibrations, highest DLS, achieved higher inclination angles in large hole sizes, and stable steering efficiency, even in unconsolidated sand formations. The hybrid bits notably minimized the right-hand walk tendency associated with PDC bits.<\/jats:p>\n               <jats:p>Over ten runs on the NCS, data indicates improved ROP, well placement, and borehole quality through drilling automation and BI tools. The digital twin continuously learns, and updates based on historical steering actions and real-time data calibration, allowing user input. Different modes can be selected for drilling efficiency based on operational constraints, objectives, and field knowledge, incorporating attitude and position control while managing projection horizon, build rate boundaries, and walk rate.<\/jats:p>\n               <jats:p>The proposed approach provides a novel perspective on drilling with Push-The-Bit RSS in larger borehole diameters, expanding the boundaries of drilling, especially in Extended Reach Drilling (ERD) wells. Furthermore, this methodology emphasizes the potential of automated drilling and automated data analytics, contributing to effective decision-making in future well planning and resulting in substantial reductions in operational and HSE risks.<\/jats:p>","DOI":"10.2523\/iptc-25097-ms","type":"proceedings-article","created":{"date-parts":[[2025,2,17]],"date-time":"2025-02-17T00:13:32Z","timestamp":1739751212000},"source":"Crossref","is-referenced-by-count":0,"title":["Innovative Strategies for Push-The-Bit Drilling Automation: Mitigating Vibrations and Maximizing Steering Efficiency in Challenging Norwegian Continental Shelf Formations and Large Hole Sizes"],"prefix":"10.2523","author":[{"given":"Farit","family":"Rakhmangulov","sequence":"additional","affiliation":[{"name":"Halliburton, Aberdeen, Scotland, United Kingdom"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Sanan","family":"Aliyev","sequence":"additional","affiliation":[{"name":"Halliburton, Stavanger, Rogaland, Norway"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"861","published-online":{"date-parts":[[2025,2,17]]},"reference":[{"key":"2025021700132889400_R1","doi-asserted-by":"crossref","unstructured":"Aliyev, S., Tengesdal, J.E., & Ngueguim, M.E.\n          2023.
