What Does Biopolymer Mud Mean?
Biopolymer mud is a type of drilling fluid used in horizontal directional drilling operations. This type of fluid consists of long polymer chains formed from naturally blended vegetable gums and organic bacteria. Biopolymer mud is preferred over other drilling fluids (such as bentonite) due to their minimal impact on the environment.
Biopolymer mud is also known as biodegradable polymer mud.
Trenchlesspedia Explains Biopolymer Mud
Biopolymer muds offer similar performance and benefits as synthetic bentonite mud when advancing the drill head. However, unlike bentonite, which can leave behind a residue that can be harmful to the environment, biopolymer mud breaks down into simple sugars and water, resulting in little to no negative effects on the environment.
Biopolymer mud, however, is more expensive than traditional synthetically made drilling fluids. In some cases, the cost can be several times that of equal volumes of bentonite. In addition, the proportions of biopolymer mud required for optimal performance can vary widely depending on the application. Inferior mix proportions may also be far less potent and less efficient than similar mixes of bentonite.
