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.

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.

The process also involves the invention and management of machines for field operations, materials handling, water control, and postharvest operations [1,2].
This exposes sensitive critical components of the machines to unpleasant weather activities, which can lead to damage by rusts and flaking in the case of plastics and rubberized materials.
Materials and Method 2.1 Area of study The study area is Lagos state in the Southwestern part of Nigeria, which has 20 local government areas (Fig. 1).

CNCs are the elementary crystallites within native cellulose materials, and can be extracted from native cellulose materials by selectively removing the amorphous cellulose sections.
Other applications that utilise CNCs for their unique physical and chemical characteristics are for example sensor materials [16-19] and as supercapacitor electrode support material [20-24].
This simple process demonstrated an energy efficient separation of CNCs from the acid and can potentially have a big impact on the industrial scale production of these materials.
Materials and methods Preparation of acid-CNC mixture.

This is an integrated system that encompasses energy medium, materials, and equipment, in-between materials, and the final products and emissions from the manufacturing processes [16].
Manufacturing processes involve the consumption of various kinds of resources( energy, water, materials, etc.) [18].
GM entails the design of green products, the use of eco-friendly raw materials, environmentally friendly packing and distribution, and after the end of life of product reuse [33].
The campaign has been launched by many nations to enhance GM practices with an emphasis on the usage of recycled materials and energy consumption regulations.
Furthermore, GM practices with an emphasis on the usage of recycled materials and energy consumption regulations.

In China, on the base of the settlement situation in Gannan Tibetan Autonomous Prefecture, ten pasturing areas in Hexi Corridor and those half-farming and half-pasturing counties, He Weiguang[4] pointed out that three modes exist in Gansu pasturing areas— settlement in towns, settlement in villages and dispersed settlement in pastureland among which settlement in towns, he thought, is the ideal mode, for it will greatly improve herdsmen’s material and cultural living conditions.
