Industrial salt, one of the most basic raw materials for the chemical industry, has sodium chloride and sodium nitrite as its main components. It is used in oil drilling, drilling fluids, completion fluids, soap making, ceramics, glass production, household chemicals, petrochemical dehydration fluids, etc.

Bentonite has the characteristic of high mud yield, high gel strength and low shear. It can improve the borehole stability especially in unconsolidated formation. The high performance and low concentration of bentonite can reduce the dosage, cost and intensity of labor. Used for oil and gas well drilling and civil-engineering including drilling fluid system for horizontal directional drilling, fluid solution for diaphragm walls and piles, lubrication fluid for micro tunneling or pipe jacking, drilling fluid for water well, exploration and mining, fluid solution for shield tunneling.

Wanli barium sulfate, also known as barite powder, is widely used as additive of drilling fluid to increase the fluid density, it can cool the drill bit and lubricate drill pipe, also it helps control well pressure so as to prevent blowout of well. We offer Barite powder include API grades 4.1 and API grades 4.2.

Silica fume, also called microsilica or micro silica, is a byproduct of production silicon metal or ferrosilicon alloys. Silicon metal and alloys are produced in electric furnaces. The raw materials are quartz, coal and woodchips.

PAC-LV and PAC-HV are white or off-white powders. They can effectively increase viscosity of water-base drilling fluid and modify flow patterns as well as control filter losses in almost all water-base drilling fluid, especially for the sea water application. The products are divided into two kinds including high viscosity and low viscosity.

CMC is white or off-white powder. CMC-LV is used as filter loss reducer, and CMC-HV is used as filter loss reducer and viscosifier. Both CMC-LV and CMC-HV have good salt resistance.CMC-LV and CMC-HV can be directly used in all water-base drilling fluid as filter loss reducer and viscosifier.

Xanthan gum is a polysaccharide secreted by the bacterium Xanthomonas. In the oil industry, xanthan gum is used in large quantities, usually to thicken drilling mud. Xanthan gum provides great "low end" rheology. The widespread use of horizontal drilling and the demand for good control of drilled solids has led to its expanded use. It has also been added to concrete poured underwater, to increase its viscosity and prevent washout.

Wanli Cenosphere is a kind of silica bead of tiny glass particle. It's widely used as lightening admixture in oil-well cement to improve liquidity of cement, delay gravity-free time, and improve the strength of slurry, heat retaining property and corrosion resistance. We offer Cenosphere powder including light grade and conventional grade.
