Di-Sperse 72L
Product #9570
Earth Pro Di-Sperse 72L is effective at any pH and due to its rapid dissolution, it immediately affects the flow properties of a drilling fluid.
Its primary function is to act as a flow control agent by reducing viscosity and gel strengths in conventional and low solids water based drilling fluids.
Features & Benefits
- A very effective thinner in carbonate/bicarbonate and sulphate contaminated muds where conventional thinners have little or no effect
- Stable up to 175°C (347°F)
- Cost-effective
- Environmentally acceptable
- Effectiveness has been proven in fresh water gel, K+ polymer, gyp and saturated salt muds up to 10,000 mg/L Cl
- Alternative to heavy metal lignosulphonates, lignites and tannis
Mixing & Handling
Actual amount required depends upon the amount of solids present in the system, concentrations for normal use range from 0.4 - 4.0 L/m³ (requirements are typically 1/4 that of lignosulphonate).
Earth Pro Di-Sperse 72L should be added directly to the mud system. This product is stable at high and low temperatures and has excellent freeze-thaw stability.
The thinning efficiency of Earth Pro Di-Sperse 72L is actually improved by the presence of moderate levels of calcium up to a maximum of 800-1000 mg/L.
