Drilling Fluid
PSG
Aminated Polysaccharides
PSG is a special modified natural polysaccharide polymer. PSG provides low chemical activity of drilling fluid and enhanced stability of shale. It has good properties of forming film, high-temperature resistance, shale inhibition, and salt resistance. It is non-toxic with the benefit of protecting oil and gas reservoirs. PSG is suitable for unconsolidated coal bed gas formations. The recommended dosage is 3-5% (v/v).
PSG Features
Forms semipermeable membrane on the interface to enhance borehole stability. It’s especially suitable for water sensitivity formation (mud stone formation, salt rock formation, soft mud stone formation, and other complex formations) Good lubricating property with the ability to be applied to horizontal wells, high angle deviated wells, and other complex wells Excellent salt contamination resistance Good filtration loss control property up to 120℃ Protects oil and gas reservoirs Non-toxic, biodegradable, suitable for building environmental-friendly drilling fluidStorage
It is a liquid packaged in 25 L, 50 L cans and 200 L drums. International packaging may vary. Should be stored in a shady and dry place with good ventilation.
Safety
