A well kick happens when formation fluids (oil, gas, or water) start to flow into the wellbore because the bottom hole pressure becomes lower than the formation pressure.
This imbalance usually occurs due to:
-Insufficient mud weight
-Swabbing while pulling out of hole
-Lost circulation zones
-Gas cutting in the mud
When a kick occurs, it’s a critical warning sign — if not controlled, it can lead to a blowout.
Kick Detection Signs:
-Sudden increase in pit volume
-Flow rate increase at constant pump speed
-Decrease in mud weight or flow out changes
-Drilling break without expected formation change
Kick Control Steps:
1.Shut in the well immediately using the BOP (Blowout Preventer).
2.Record shut-in pressures (SIDPP and SICP).
3.Circulate out the influx using the Driller’s or Wait and Weight method.
4.Adjust mud weight to reestablish balance.
Safety starts with awareness — every crew member must be trained to detect early signs and react fast.
