Making a flow check to verify a kick can cause extra risks

The main cause of a kick is the insufficient head of drilling fluid to stop the entry of formation fluid into the well bore. This could arise because of unexpectedly high formation pressure, low circulation, swab during a trip out, or failure to fill up hole during a trip out. Kicks can be detected by monitoring surface indication on the rig. An influx in the well can be indicated by a drilling break, pressure drop, increase in pump strokes per minute, pit gain, etc. The most reliable and widely followed mode of kick detection is monitoring the fluid balance in the well by making a flow check.
