AI-Based Kick Detection for Drilling Rigs
Short answer. AI-based kick detection estimates, in real time, the probability that formation fluid is entering the wellbore, using flow-in/flow-out, pit volume, standpipe pressure, hook load and rate of penetration together. AgenticNex AI combines physics-based flow balance with ML and context from offset wells.
What is the business problem?
Early kick indicators are small and easily masked by rig activities such as connections, pump changes and pipe movement.
Why can conventional approaches be insufficient?
- Pit-gain thresholds trigger late or on rig activity.
- Flow-out sensors are noisy and poorly calibrated.
- Models ignore formation pressure context from offset wells.
What is our engineering approach?
- Detect rig state so connections and pump changes are not misread.
- Compute flow balance and pit trends with noise filtering.
- Score influx probability with physics + ML.
- Attach offset-well and formation context from the knowledge graph.

Frequently asked questions
Which sensors does kick detection need?
At minimum flow-in, pit volume, standpipe pressure and hook load. Flow-out and gas readings improve accuracy.
