Filtration Control Agents (also known as fluid loss additives) are vital components in drilling fluids. Their main function is to reduce the loss of fluid to the surrounding formation by forming a thin, low-permeability filter cake on the wellbore walls. This helps in maintaining wellbore stability and preventing formation damage.

• Minimize fluid loss into permeable formations.

• Prevent differential sticking and formation damage.

• Improve the quality of the filter cake for better wellbore integrity.
