This blog post will demonstrate you about flow check.
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.
