Pioneering Autonomous Deepsea Drilling with Halliburton and Sekal
In a landmark achievement for the energy sector, Halliburton and Sekal AS have successfully deployed the world’s first automated on-bottom drilling system.
This cutting-edge technology was utilized to drill a well for Equinor on the Norwegian Continental Shelf, marking a significant advancement in offshore drilling operations.
Integrating Advanced Technologies
The innovative system is a seamless integration of Halliburton’s LOGIX™ automation and remote operations platform, Sekal’s Drilltronics®, and the rig’s automation control system. This fusion creates an integrated closed-loop control solution that orchestrates autonomous directional drilling, automated wellbore hydraulics, and dynamic control of surface drilling equipment.
By coupling real-time advanced models of the subsurface, wellbore fluid dynamics, and pressure systems with intelligent directional drilling tools and the rig’s automation control system, the technology optimizes well placement and ensures drilling operations remain within safe parameters.
Real-Time Optimization and Precision
One of the standout features of this system is its ability to optimize drilling parameters in real-time. With the push of a single button, operators can achieve precise well placement through integrated automated rig controls. This capability not only enhances operational efficiency but also significantly reduces the margin for human error.
Josh Sears, Senior Vice President of Drilling and Evaluation at Halliburton, emphasized the project’s significance: “This project demonstrated autonomous on-bottom drilling where we orchestrated industry-leading technology of well placement, wellbore integrity, and rig process automation. The future for drilling automation is bright, and it is here.”
Comprehensive Automation Solutions
The deployed solution encompasses several advanced functionalities:
- LOGIX Orchestration: Streamlines drilling operations by integrating various automated processes.
- Auto Steer: Facilitates autonomous directional drilling adjustments.
- Vibration Mitigation: Reduces equipment wear and tear by managing and minimizing vibrations.
- Hole Cleaning Optimization: Ensures efficient removal of drill cuttings to maintain optimal drilling conditions.
Sekal’s Drilltronics® adds dynamic safeguards and automation functions, further enhancing the system’s reliability and safety.
Jarle Vaag, Chief Executive Officer of Sekal, highlighted the collaboration’s success: “With the execution of integrated automation, Halliburton and Sekal proved the benefits and viability of autonomous on-bottom drilling.”
Implications for the Energy Industry
This ground-breaking deployment signifies a transformative shift in offshore drilling operations. The integration of advanced automation technologies promises to enhance operational efficiency, improve safety standards, and reduce environmental impact. As the energy industry continues to evolve, such innovations are poised to play a pivotal role in meeting global energy demands sustainably.
