PRODUCTS TECHNICAL DATA
PRODUCT NAME :Biopolymeric viscosifier, ME-VISL
Biopolymeric viscosifier, ME-VISL can also be used in solid free or low solid drilling fluid to improve structural viscosity and enhance the carrying capacity of working fluid.
At the same time, it can effectively prevent formation pollution caused by the filtration of working fluid.
Application scope and main characteristics
1. Has good temperature and salt resistance, use in Drilling (including horizontal drilling, drill-in fluids, under-reaming, and coiled tubing operations)
2. Gravel packing
3. Well control
4. Sand-washing 2. Good solubility, no water, insoluble matter and residue, biodegradable, no damage to the formation.
5. Biopolymeric viscosifier, ME-VISL should be used when high shear is unavailable, or fast dispersion is required. It can be used up to 250°F (120°C).
Appearance: free flowing powder. Recommended dosage: Add 0.3 to 3 quarts/bbl (0.28-2.8 l/bbl) to drilling fluids.
