One method is monitoring pit gain, which involves tracking fluid gains in the pits that might indicate flow from the well. Another method is the analysis of flow‐out versus flow‐in data – which should be equal if the well is stable. As discussed by Dr. John Smith in his report, these two methods – pit gain and comparison of flow‐in to flow‐out – are critical to effective well monitoring. 247 In addition, other data (including drill pipe pressure changes and gas content information) can also indicate if a well is flowing.
