Term · Oil and gas · MLC-T-OAG-002679

An obstruction in the annulus of a wellbore caused by an accumulation of cuttings, cavings, or other debris. This condition can restrict fluid circulation, increase pump pressure, and potentially stick the drill string. It often occurs in deviated wells or unstable formations and requires remedial action such as increasing flow rate or circulating bottoms up.
