1、Calcium chloride can be used in oil field drilling, stabilizing mud layers, lubricating drilling, drilling, and cementing in the petroleum industry.

2、Bentonite is a non-metallic mineral primarily composed of montmorillonite. Also known as bentonite rock, saponite, or swelling clay, it forms a paste-like consistency when mixed with water. Any clay exhibiting this property is generally referred to as bentonite.In drilling operations, bentonite is used to prepare drilling mud suspensions with high rheological and thixotropic properties, offering excellent slurry-forming and lubricating capabilities. It is a premium raw material for mud formulation.

3、Carboxymethyl Starch（CMS) is used as drilling fluid additive, it reduces fluid loss and enhances mud stability (heat-resistant up to 120°C), also used as fracturing fluid thickener, partially replaces guar gum, lowering costs.

4、Polyacrylamide (PAM) is used to be drilling mud additive：Enhances drilling bit lifespan, improves drilling speed, prevents borehole collapse, and reduces diamond bit clogging in oil/gas/coal exploration.Also used as a fracturing fluid and water shutoff agent in oilfields

5、Polyaluminium Chloride (PAC) is utilized in the petroleum and chemical industry forOilfield Water Injection Treatment Inhibits pipeline corrosionand Catalyst Support in Petroleum Cracking

6、In the petroleum industry, aluminum fluoride is used as a drilling and oil recovery agent. It can effectively reduce the surface tension of drilling fluid and oil production fluid, and improve the fluidity, which is beneficial to drilling and oil production.
