PAP-1
Amine Based Shale Inhibitor
PAP-1 is a new type of shale inhibitors used in high-performance water-based drilling fluid. PAP-1 possesses good cationic absorbability, inhibitory capacity and a long duration of action. The introduction of amines compounds provides greater shale inhibition and its anti-collapse mechanism is different from the ordinary polyether products. PAP-1 is designed to be firmly absorbed on the clay to reduce the clay layer spacing and hence prevent water from invading into the formation. The product can be directly added to all kinds of water-base drilling. The recommended dosage is 0.5-1% (v/v).
PAP-1 Features
Inhibits shale effectively with minimal viscosity and filtration loss increasing, controls the clays dispersing, prevent bit balling. It’s especially suitable for soft mud stone formation, salt gypsum formation, water-sensitive formation, and other complex formations Adheres to clay interlamination Strong inhibition capability, reduces surface tension No influence on rheological properties and fluid loss Stabilizes borehole by reducing clay spacing and inhibiting water from getting into formation Resists salt, calcium, and magnesium. Can be applied to freshwater, brine, seawater drilling, and completion fluids Performs well under high temperature up to 200℃ and is suitable for deep wells and ultra-deep wells Freezing point is low, has cold-resistance, can be used in cold areas Protects oil and gas reservoirs Good compatibilityStorage
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.
