mudding off

1. n. [Drilling Fluids]
The action of coating rock grains and plugging off the permeability of a productive reservoir during drilling. The term is seldom used today, but refers to formation damage by mud solids. By proper selection of solids, such as bridging materials and drill-in fluids, mudding off can be minimized.
