Di-Sperse 74
Product #9580
Earth Pro Di-Sperse 74 functions primarily as a flow control agent by reducing viscosity and gel strengths. It offers improved capabilities in high solids and contaminated muds and offers increased thermal stability over Earth Pro Di-Sperse 72L when drilling in green cement, salt or anhydrite stringers.
Mixing & Handling
Actual amount required depends upon the amount of solids present in the system, concentrations for normal use range from 0.3 - 3.0 L/m³ (requirements are typically 1/4 that of lignosulphonate).
A highly concentrated pill of Earth Pro Di-Sperse 74 will induce well cake breakdown prior to completion, cementing or stimulation operations.
Earth Pro Di-Sperse 74 should be added directly to the mud system through a mud hopper. This product is stable at high and low temperatures and has excellent freeze-thaw stability.
