What is flow check?

Flow check is the period that you stop operations such as drilling, tripping pipe and circulating and monitor the well in order to see whether the well is static or not. The time for flow check should be enough to confirm the status of a well. It might be few minutes or it could be as long as 30 minutes depending on the well situation. Normally, many operators require 15 minutes flow check if the well is in normal condition.



How to execute the flow check?

1. Stop the current operation as stop drilling, circulating, tripping pipe, etc.

2. Space out pipe at rotary table. We need to do it because if the well is flowing while flow checking, we can immediately shut the well in.

3. Monitor a well either on a trip tank or without trip tank. I personally prefer to monitor the well on the trip tank because it can tell me that well is giving me fluid or l am losing fluid while monitor well.

4. If the well is in static condition that means no increase in volume in trip tank or flow at flow line, you can continue your current operation. If the well is flowing (you will see volume increase in the trip tank), you need to stop and attempt to figure out how to kill the well.
