Chrome- Free Lignosulfonate
Specification:
Insoluble alkaline material (%): 2.5 max

Chrome-free lignosulfonate 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
Lignosulfonate (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%.
Package:
Packed in 25 kg net weight moisture proof multi-wall paper bags,
with PE film inside.

Ferro Chrome lignosulfonate can be used in all dispersed water-
based system to effectively control the rheological properties at
elevated temperatures and to minimize adverse effects of mud
contamination. Ferrochrome lignosulfonate functions well in lime,
gypsum, salt water, and fresh water fluids.
