PRODUCT NAME

CALCIUM CHLORIDEM*

Description Calcium Chloride (CaCl2) powder is single salt used as soluble weighting agent and source of calcium
Function Used to form clear-brine workover and completion fluid with densities ranging from 8.4 to 11.8 lb/ gal. Inhibits hydration and migration of swelling clays. Used in invert emulsion mud to adjust the activity of the water phase.

PAL CARBS*

Description CaCO3 is Acid Soluble weighting or bridging agent
Function Acid-soluble bridging and weighting agent for controlling fluid loss and density in drilling, workover & completion.

PAL CARB-SS*

Description Sized Calcium Carbonate
Function Acid-soluble bridging and weighting agent for controlling fluid loss and density. Available in Fine, Medium & Coarse grades.

SODIUM HYDROXIDES*

Description Sodium hydroxide to control pH
Function Used to maintain or increase pH. Increasing pH with NaOH precipitates magnesium (Mg 2+) and suppresses (Ca2+) in high hardness water, reduces corrosion and neutralizes acid gases such as carbon dioxide and hydrogen sulfide.

GYPSUMS*

Description Gypsum (Calcium sulfate (CaSO42H2O)) to treat carbonate contamination in high pH mud
Function Source of Ca ion, used to reduce carbonate ion contamination, without increasing the pH in freshwater and seawater muds.

PAL LIMES*

Description Calcium Hydroxide for Alkalinity control & bicarbonate contamination. Primary invert emulsion mud component
Function Economical source of calcium and alkalinity in water and oil base muds. Flocculating agent in spud mud for improved hole cleaning, removes soluble carbonate ions, controls corrosion and activates fatty acid in oil base mud.

PAL LIME OS*

Description Calcium Oxide
Function Used as a source of alkalinity to elevate pH, buffer aqueous fluids at high pH, flocculate bentonite, precipitate soluble carbonate ions, and saponified fatty acid emulsifiers.

KClS*

Description KCl, Potassium Chloride
Function Used to form clear-brine workover and completion fluid with densities ranging from 8.4 to 9.7 lb/ gal. Inhibits hydration and migration of swelling clays.

KOHS*

Description KOH, Caustic Potash, Potassium Hydroxide
Function Used to maintain or increase pH, inhibitor for swelling shales. Used instead of caustic soda to reduce the sodium ion content and avoid dispersion of clays in inhibitive water-base fluids and drill-in fluids. Increasing pH with KOH precipitates magnesium (Mg 2+) and suppresses (Ca2+) in high hardness water, reduces corrosion and neutralizes acid gases such as carbon dioxide and hydrogen sulfide.

POTASSIUM IODIDE S*

Description Is used as a tracer in water base Mud
Function Used as a tracer in water base muds to determine mud filtrate invasion in formation.

SAPPS*

Description Sodium Acid Pyrophosphate (Na2H2P2O7) is an effective dispersant and protect against cement contamination
Function Efficient dispersant in low-weight fresh water muds used in up hole drilling and effective additive for treating cement contamination and reduce viscosity.

SODA ASHS*

Description Sodium carbonate to treat Ca ion out in makeup water and to remove Calcium Contamination particularly due to Anhydrite
Function Used as a source of carbonate ions to precipitate & remove soluble calcium from water base fluids and makeup waters. Provide effective treatment for Calcium Contamination particularly due to Anhydrite, increases pH and flocculates spud mud.

PAL MGOM*

Description Magnesium Oxide, Anhydrous
Function Used as a pH buffering agent, promotes temperature stability and enhances the rheological and filtration properties of water base drilling fluid at high temperature.

SALTS*

Description NaCl for weight up and Salt Saturated System 
Function Used to form clear-brine workover and completion fluid with densities ranging from 8.4 to 10 lb/ gal. Increase shale inhibition by decreasing water activity, reducing formation salt dissolution, reducing freezing point of water base fluids and reducing the potential of forming gas hydrates.

SODIUM CHROMATES*

Description Na2CrO4, sodium salt in which chromium atoms are in the plus-6 valence state
Function Used as corrosion inhibitor.

SODIUM DICHROMATES*

Description Na2Cr2O7, sodium salt in which chromium atoms are in the plus-7 valence state
Function Is used as corrosion inhibitor and to prevent temperature gelation.

SODIUM NITRATES*

Description Long term tracer
Function Used as long term tracer in water base muds to determine mud filtrate invasion in formation.

PAL BROM ZnM*

Description Zinc Bromide Liquid, used for mixing high density, solids free completion brines
Function Used to formulate clear-brine workover and completion fluid which requires density to 19.2 lb/ gal. Inhibits hydration and migration of swelling clays.

CITRIC ACIDS*

Description Citric Acid for Cement Contamination
Function Reduce pH and removes calcium to pretreat or remedy cement contamination, sequesters soluble iron to prevent polymer crosslinking in the drilling fluid system.

SODIUM BICARBONATES*

Description Sodium bicarbonate. To remove calcium
Function Used as a source of bicarbonate ions to precipitate & remove soluble calcium from water base fluids and reduce pH. Provide effective treatment for cement contamination and deflocculates cement contaminated fluids.
