Details: |
Tannin extract (also Quebracho tannin and Quebracho extract) is a natural extract from quebracho and Chinese gallnut trees. Sulfonated tannin extract or SMK is made from tannin extract by sulfonation process and other chemical modifications. It is a free flowing brown powder with non-toxic, non-polluting and none heavy metal ions. SMK has excellent thinning capacity in all type of water base drilling mud systems, particularly in polymer fluids. It can effectively reduce the viscosity and shear strength of drilling muds. It can improve drilling fluids' thermal stability and control their rheological properties under high temperature up to 180℃. Sulfonated tannin extract has a good compatibility with all common water base mud additives. Bichain is one of reliable sulfonated (Quebracho) tannin extract suppliers and manufacturers of SMK for water based drilling in HPHT wells. We supply high quality sulfonated tannin extract like Mil-Quebracho.
