Product Dose: 

CITRIC ACID is primarily used as a pH buffer, a low solids, non-dispersed, low pH drilling fluid.

CITRIC ACID is primarily used to quickly reduce the pH in  drilling fluid. One of the benefits of using Citric Acid is that it forms Sodium Citrate in the presence of Sodium based polymers such as DMA and OMNIPOL II. Sodium Citrate acts as a dispersant in water based fluids, helping to control the rheology. A third benefit of CITRIC ACID is the reduced hazard to personnel when compared to other acids normally used in drilling applications. CITRIC ACID will not reduce hardness levels in drilling fluids as will phosphoric acid.

CITRIC ACID is added through the hopper when using the dry material, and added directly to the drilling fluid when using the liquid. A diaphragm-
metering pump may be utilized with the liquid for continuous
pH control.
Treatment levels vary with the concentration of salts, particularly hydrogen (H+) and hydroxide (OH- ).

CITRIC ACID provides a layer of hydrogen ions around active clays, reducing their zeta potential and thus reducing their ability to imbibe water. This function translates to fewer solids, less swelling of the solids in the drilling fluid, reduced wellbore swelling, and more efficient solids control equipment function. A secondary benefit of CITRIC ACID is the formation of sodium citrate, a thinner. This helps counteract the flocculating influence of the hydrogen ions on first being introduced to the drilling fluid system.
