Our offered chemical is used in drilling at densely populated area and offshore. Along with this, the Chrome Free Lignosulphonate is available in varied packaging options at marginal price for our valuable clients.
Packaging: Material packed in 25kg HDPE bag.
Safety and Handling:
Material must be handled as an Industrial chemical, wearing protective equipment and observing the precautions as mentioned in the MSDS. Chrome-free lignosulphonate is a drilling mud thinner produced by multi chemical reactions followed by drying of natural high molecular weight compound, organic material and harmless metal ions. The product contains no chromium heavy metal and is ideal for use in drilling at densely populated area and offshore.
Thinning performance:
Test results indicate the thinning performance in fresh water based mud under normal temperature is comparable to ferrochrome lignosulphonate (FCLS). At elevated temperature, it performs better than FCLS in either fresh water or salt-water based mud, particularly the later. The product is suitable for use in drilling under complex geological formation, in water with high TDS, or in offshore drilling.
Good fluid loss control properties:
Its major advantage is the thinning effect in drilling mud with high solid content, and simultaneously controls the fluid loss. Its fluid loss control action is better than FCLS and the mud cake formed is smooth and compressible, thus beneficial for well bore protection and fluid loss reduction under high-pressure condition.
Higher retention of solid:
The product has improved solid retaining capacity due to its excellent thinning properties. Even when the mud is mixed with large quantity of clay while drilling, the rock scarps can still maintain good mobility. In addition it is capable of withstanding contamination by calcium, magnesium and sodium electrolytes, making it an ideal thinning agent for heavy weight mud.
Recommended dosage:
For salt water and fresh water based mud, a range of 0.5 to 1.0% is recommended depending on the specific conditions. Under special situations such as high solid and metal electrolytes content, a slight increase in dosage is recommended but not to exceed 2.0%.
