DETECT STICK-
SLIP SYMPTOMS
TO AVERT DAMAGING CONSEQUENCES
Exebenus Spotter Vibration Agent
The Vibration Agent guards against hazards related to torsional vibration and stick-slip during drilling.
By alerting drillers to vibration-related issues, the agent helps ensure that downhole tools perform optimally and wellbore stability is maintained, which in turn protects the reliability of downhole measurements.
If stick-slip symptoms are detected and exceeds a threshold value, the Vibration Agent triggers the ROP Agent to stop issuing drilling parameter advice, preventing actions that could exacerbate the vibration issue. Once vibration issues are mitigated and the risk of stick-slip diminishes, the ROP Agent automatically resumes its recommendations.

Stronger together
Exebenus Spotter agents are available as standalone solutions, or they can be deployed in bundles, creating powerful synergies that enhance drilling efficiency.
All in real time. All the time.
Working together, the Vibration and ROP agents draw on each other to optimize drilling performance. The Vibration Agent continuously monitors RPM and torque in real time. It recognizes increases in torque fluctuation signals as potential torsional vibration, and estimates the probability of stick-slip events. The ROP Agent, in turn, factors the vibration data into its drilling parameter recommendations.
Used together, these agents address interconnected challenges, leading to better performance than either could achieve alone.
Case study
ROP optimized while stick-slip incidents averted
In a Middle Eastern operation, the ROP Agent was configured to pause issuing drilling parameter advice during periods with high stick-slip probabilities. During the shaded region (A), towards the end of an interval with higher WOB values, high stick-slip probabilities were observed, triggering a notification to the user that stick-slip symptoms had been detected. During this period, the ROP (grey curve) fell sharply.
At point (B), the rig crew reduced the WOB and increased rotary speed, resulting in a decrease in stick-slip probability and a brief increase in ROP. Around point (C), where WOB was relatively low, the optimizer advised a 10% WOB increase. This adjustment was implemented while maintaining the higher rotary speed and led to a clear ROP improvement at point (D), from approximately 45 m/h to an ROP average of 75 m/h for the remainder of the stand.
During the final drilling phase, stick-slip probabilities remained low, further indicating enhanced drilling efficiency.
