Since the 1980s, intensive work has been done to enable drilling fluids
to meet constantly increasing requirements. They are to remain as fluid
as possible when subjected to high pressure and extreme temperature
fluctuations even in the case of highly deviated and deepwater

must lubricate the drill bit in a large variety of rock formations.
Finally, they should be environmentally compatible and biodegradable
and safe for people and equipment.
