Most of the industries used coal as non-renewable materials for reductant in nickel ore processing, which contributed to high acidic pollutant emission due to the sulfur dioxide and nitrogen oxide released into the air during the reduction/combustion process [12-13].
The study of biomass as a renewable material for reductant in nickel ore processing should be investigated for lowering the pollutant emission [14].

Accidents involving hazardous products occur when the risk becomes uncontrollable, resulting in a leak that can cause harm to human health, material losses, and/or environmental impacts.
Additionally, public awareness of the risks associated with the transportation of hazardous materials is crucial for promoting a proactive approach to accident prevention.

Serious loss circulation happened several times that 40 ton of circulation materials like polymer sealing agent, sawdust, cotton seed shell and soybean were consumed in total, but circulation could not be set up and it was unable to drill to the formation of interest in the third section when the depth reached to 1074m.
Conclusions Laboratory evaluations and field applications show that fuzzy-ball drilling fluid differs from other types of drilling fluid containing inert sealing materials, it has many advantages as follows
Then, it can effectively balance the high pressure of reservoir by making use of inert weighting materials to improve its density.
In addition, further thanks to National Science and Technology for providing research funding.
