Release 2.7
Higher precision, less noise, smarter decisions
ML Agents deliver higher performance with less effort
Release #: Release 2.7
Date: December 27, 2024
Exebenus Spotter 2.7 delivers significant improvements to the performance and accuracy of its ML agents. The updated ROP Agent features a new machine learning model that better utilizes weight-on-bit (WOB) data and reduces bias toward RPM adjustments, enabling more precise parameter tuning. A new torsional vibration model supports enhanced stick-slip detection and works in tandem with the Stuck Pipe Agent to deliver more context-aware warnings with fewer false positives. Together, these updates reduce manual effort and improve confidence in real-time drilling decisions.

With Exebenus Spotter 2.7, we’ve done more than just refine algorithms—we’ve overcome technical challenges that many considered unsolvable. Turning high-frequency, noisy drilling data into real-time, context-aware guidance has long been an aspiration in the industry. With this release, we’ve made it a practical reality. Our ML agents now deliver more precise, targeted insights with less operational overhead, helping our customers make faster, smarter decisions with greater confidence.

ROP Agent
Provides improved weight-on-bit (WOB) recommendations, making it easier to evaluate the impact of WOB adjustments and support informed operational decisions.
- New and enhanced ROP model
- Expected ROP gain curve shows percentage improvement achievable from advised parameters
- Reduced bias toward recommending RPM changes in certain scenarios
- Improved utilization of WOB data to estimate expected ROP

Stuck Pipe Agent
The updated Stuck Pipe Agent improves precision and significantly reduces false positives. Dynamic thresholding now adapts under high-drag conditions, lowering false warnings to fewer than one per operational day.
- Upgraded real-time warning systems for detecting mechanical restrictions
- Real-time alerts based on drill string up-weight and down-weight tracking to identify mechanical restrictions
- Enhanced ability to distinguish “normal” reaming from true restriction scenarios
- Alerts based on short-timescale hookload changes in dynamic conditions, now incorporate the latest up-weight and down-weight estimates to adapt to the operational context and reduce false alerts

Vibration Agent
The Vibration Agent detects torsional vibration (stick-slip) and supports the Stuck Pipe Agent by improving precision and delivering context-rich warnings—reducing unnecessary alarms.
- Dynamic torque warnings replaced with INFO-level messages when severe stick-slip symptoms are detected
- Reduces warning volume in high-vibration scenarios prioritizing context over raw signal triggers
The screenshot shows a Gulf of Mexico well, where the Stuck Pipe Agent and Vibration Agent were run in combination. After drilling the 28-degree 10 5/8” x 12 1/4” section, the operator performed a wiper-trip from 4473 m back to 4000 m to clean the wellbore. This action was taken in response to multiple torque (A) and fluid friction (ECD increase) alerts (B) triggered several hours earlier by the Stuck Pipe Agent, as well as significant stick-slip conditions (C) detected by the Vibration Agent while reaming off-bottom. These warnings were observed above a salt layer at a depth of approximately 4500 m and were interpreted as indications of a sticky or tight formation—likely caused by salt creeping into the formation (a “dirty formation” scenario). The preventive wipe trip (D) successfully mitigated the risk of a stuck ppe incident.
