Chapter 2. Fluid Loss Additives
Comparative tables of fluid loss additives, also called filtrate-reducing agents, can be found on the internet (Petrochem 2009). Losses may occur when the fluid comes in contact with a porous formation. This is relevant for drilling and completion fluids, fracturing fluids, and cement slurries.
The extent of fluid loss is dependent on the porosity and thus the permeability of the formation, and it may reach approximately 10 t/h. Because the fluids used in petroleum technology are in some cases quite expensive, an extensive fluid loss may not be tolerable. Of course there are also environmental reasons to prevent fluid loss.

Mechanism of Action of Fluid Loss Agents

Reduced fluid loss is achieved by plugging a porous ...
