Apparatuses and methods useable in drilling installations having a mud loop for detecting ongoing or imminent kick events are provided. An apparatus 100 includes a first sensor 110 configured to measure a input mud flow pumped into the well, and a second sensor 120 configured to measure a variation of a return mud flow emerging from the well. The apparatus further includes a controller 130 connected to the first sensor 110, and to the second sensor 120. The controller is configured to identify an ongoing or imminent kick event based on monitoring and comparing an evolution of the input mud flow as measured by the first sensor and an evolution of the return mud flow as inferred based on measurements received from the second sensor. Additionally, a third sensor 140 can be included in the apparatus to confirm the conclusion made by the controller before alerting the user that a kick has likely occurred. |
