Definition:
A kick is an unintended influx of formation fluids (like gas, oil, or water) into the wellbore during drilling operations. This happens when the pressure in the formation exceeds the pressure exerted by the drilling mud, causing formation fluids to flow into the well.
Why It Matters:
If not detected and controlled early, a kick can lead to a blowout, posing serious safety and environmental risks.
Common Indicators of a Kick:
- Sudden increase in drilling mud return flow
- Change in mud pit volume
- Unexpected changes in drill string pressure
Used In Context:
“The crew detected a kick and immediately began well control procedures.”
