The MUDGARD filter removed all fluid-born debris before it could damage any critical BHA components, enabling the operator to drill the 392-m [1,286-ft] sidetrack in less than 100 rotating and pumping hours. The BHA tools performed flawlessly—with no reported pressure- or debris-related complications. In total, the MUDGARD filter captured 1.5 kg of mixed debris, which could have invaded the BHA and caused a component failure or plugged a bit nozzle.
