While-Drilling LCM
Polymer While-Drilling Lost Circulation Material
A novel high-polymer while-drilling LCM combining plugging, anti-sloughing and lubricating functions. It disperses quickly in the mud and forms a dense, erosion- and aging-resistant seal in micro-fractures and pores as drilling proceeds, controlling losses without stopping to spot a conventional treatment.
