Abstract

The invention relates to a method of monitoring drilling fluid return flow rate when drilling a hydrocarbon well during which the drilling fluid is circulated down through a drill string, up through an annulus of the hydrocarbon well, through a wellhead diverter (25), through a flowline (23) to a solids control and active mud system (27) and back down through the drill string, wherein the drilling fluid, between the wellhead diverter and the solids control and active mud system, is routed through a drilling fluid flow rate monitoring system (61). The method comprises the steps of routing the drilling fluid through at least one measuring tank (29a, 29b) and at least one tank pump (31, 33) which is arranged downstream of the at least one measuring tank; monitoring the drilling fluid level in the at least one measuring tank; monitoring the flow rate of drilling fluid going through the at least one tank pump; and establishing the drilling fluid return flow rate based on the monitored fluid level in the at least one measuring tank and the monitored flow rate through the at least one tank pump. The invention also relates to a system for implementing the method.The invention relates to a method of monitoring drilling fluid return flow rate when drilling a hydrocarbon well during which the drilling fluid is circulated down through a drill string, up through an annulus of the hydrocarbon well, through a wellhead diverter (25), through a flowline (23) to a solids control and active mud system (27) and back down through the drill string, wherein the drilling fluid, between the wellhead diverter and the solids control and active mud system, is routed through a drilling fluid flow rate monitoring system (61).
