MEG (Methylglucoside) is a chemical derivative of glucose, it can form semipermeable membrane and reduce the activity of water when it is added into the drilling fluid, so it can stabilize wellbore by controlling the movement of water.

Anti-sloughing water-based drilling fluid systems for offshore drilling developed since the 1990s,including silicate system,formate system,methylglucoside system and polyols system.
