Bentonite for mud

 Sinogel API-13A is an API-13A grade bentonite and can be used for oil and gas well drilling and civil-engineering incl. applied drilling fluid system for horizontal directional drilling (HDD), applied fluid solutions for diaphragm walls and piles, grouting, lubrication fluids for micro tunneling or pipe jacking, sealing ponds and irrigation ditches, drilling fluids for water well, exploration and mining, fluids solution for shield tunneling.


Sinogel GTC4 is a bentonite characterized by its high yield, high gel strength and low shear. It can improve the borehole stability especially in unconsolidated formations. The high performance and low concentration of the bentonite can reduce the quantity of the usage, the costs and the labor during transportation and mixing.
