When observing any warning sign for a kick, what is the next step?

When observing any warning sign for a kick, conducting a flow check is essential as it allows the wellsite team to assess the current condition of the well and determine if there is indeed a kick occurring. A flow check involves monitoring the flow rate of the well by assessing the fluid levels in the pit and comparing them to the expected volumes based on the drilling operations.

This step provides crucial information—if there is a significant increase in flow or a noticeable change in the pit levels, it signals that a kick might be in progress. Reacting with a flow check enables the team to take appropriate measures based on concrete data rather than assumptions. Following this, they can take further actions such as increasing mud weight or shutting down pumps, but confirming the situation through a flow check is the most immediate and critical step in responding to warning signs.
