Chrome free lignosulphonate is an emulsifier for oil in water ***** is used in different kinds of mud, because of its filtration control capacity and perfact thinning performance and powerful anti-electrolytes capacity. 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. 1. Thinning PerformanceTest 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.
