| Sino-Gel API
-4is an API - 4 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, lubrication fluids
for micro tunneling or pipe jacking, drilling fluids for water
well, exploration and mining, fluids solution for shield tunneling.
Sino-Gel Standard GTC4is a
bentonite characterized by its high yield, high gel strength and
low shear. It is a suitable product for civil-engineering incl.
applied drilling fluid system for horizontal directional drilling
(HDD), applied fluid solutions for diaphragm walls and piles,
lubrication fluids for micro tunneling or pipe jacking and shield
tunneling. 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.
