NOV's Drilling Beliefs & Analytics advances digital operations in Egypt

DBA uses a Bayesian probabilistic framework to analyze key drilling parameters, such as weight on bit (WOB), torque, mechanical specific energy, and depth of cut. By continuously updating belief indices for drilling dysfunctions, the system provides real-time, actionable insights into well conditions, enabling early detection and proactive mitigation.

NOV's local experts helped drive adoption from the start. On-the-ground support, training, and collaboration made DBA part of everyday workflows and set the foundation for continued results.

For one major operator, early DBA trials delivered consistent results across multiple wells in the Western Desert. As confidence grew, DBA expanded from two rigs to the full fleet. That expansion directly supported the launch of Egypt's first RTOC, where a single engineer now monitors multiple rigs with DBA acting as a digital assistant.

Recently, the combination of DBA and the RTOC prevented a costly stuck pipe incident for the operator. While drilling the 8.5-in. section, the DBA Stuck Pipe Risk belief repeatedly flagged elevated risk levels, coinciding with excessive overpulls. This early detection enabled the RTOC to collaborate with the rig site personnel, who quickly identified and corrected improper drill-off procedures. As a result, overpulls decreased and stuck pipe events were avoided, saving an estimated $120,000.

Following the success of this RTOC, another Egyptian operator initiated a competitive trial among several global digital service providers. NOV won the trial because DBA delivered faster, more actionable insights while integrating seamlessly into existing workflows.

Unlike cloud-dependent solutions, DBA runs at the edge, ensuring calculations and AI-driven insights are available with zero lag time-even in remote environments with limited connectivity. As integrated applications on NOV's Max™ Platform, DBA works alongside the proven WellData™ 4.0 remote drilling monitoring system and RigSense™ electronic drilling recorder to provide a single version of the truth. This unified data visualization enables real-time insights and collaboration from the rig to the office and RTOC.

Early successes included the rig crew noticing unexpectedly low ROP while drilling through a uniform sandstone and siltstone formation, despite stable parameters. DBA Bit Weight Autozero revealed that the bit weight had not been properly zeroed closer to the bottom, limiting effective weight transfer. Acting on this insight, the crew re-zeroed just above bottom to eliminate drag effects, unlocking an increase in ROP. The adjustment restored optimal WOB transfers, saving 8.2 hours of drilling time and approximately $26,000 in costs.

DBA's success in Egypt highlights how a digitally integrated, AI-driven workflow enables the industry to shift from reactive to predictive drilling operations. Through enhanced situational awareness and a customer success methodology, DBA empowers crews to act decisively, improving well delivery and reducing downtime.
