PAL BIO AS*

Description Biocide Amine based, Quaternary Ammonium compounds
Function Prevent bacterial degradation of drilling mud.

PAL BIO GS*

Description Biocide Glutaraldehyde based
Function Prevent bacterial degradation. It is de-activated by ammonia, primary amines and oxygen scavengers.

PAL SCAV HSM*

Description Organic H2S scavenger, Triazine based
Function Provides solid free H2S scrubbing for brine based drilling fluid in neutral-high pH conditions.

PAL OXAL HS S*

Description H2S scavenger Glyoxal based
Function Displays a continuous H2S scavenging activity over longer time period. Exhibits good temperature stability up to 150°C and intended for use in low pH conditions.

PAL OS S*

Description Bisulfite-based oxygen scavenger
Function Removes dissolved oxygen from drilling and completion fluids, eliminating a potential source of corrosion. Suitable for use in freshwater and monovalent brines, incompatible with Gultaraldehyde base biocide.

PAL OS-PS*

Description Sulfite-based oxygen scavenger powder
Function Removes dissolved oxygen from drilling and completion fluids, eliminating a potential source of corrosion. Improves thermal stability of polymers by a margin of 20°F (11.1°C). Suitable for use in freshwater and mono-valent brines.

PAL ERYT OS S*

Description Sodium Erythorbate based oxygen scavenger
Function Non-sulfite oxygen scavenger suitable for mono valent and divalent brines.

PAL ZNOS*

Description ZINC OXIDE material reacts with sulfides to form ZnS
Function Efficient H2S scavenger, Zinc oxide reacts with sulfides to form ZnS precipitate, which is an insoluble, inert, fine solid remain harmlessly in the drilling fluid and removed through the solids‐control equipment.
