Well Control Procedure - While Out of Hole
To detect a kick while the string is out of hole it is essential that drilling fluid is circulated across the well and trip tank at all times. Automatic alarms should be set to provide early audible/visual warning of an increase/decrease in the trip tank level.
Should it be necessary to close the Blind/Shear Rams, arrangements shall be made to circulate across the well and a fluid-level monitoring tank below the Blind Rams.
