During the process of oil and gas drilling, large volumes of drilling cuttings, waste mud, sewage water and oil sludge will be produced. Traditional disposal method is that these wastes will be solidified or separated of solid from liquid, and then be buried, burned or biologically disposed, which could not realize ZERO discharge in the real sense, and which will result in secondary pollution to the soil, water source as well as the air.

At present, drilling waste injection is the only mature and industrialized method all over the world which realizes ZERO discharge of drilling waste in the real sense. Drilling waste injection method has been applied by many world famous oil companies such as Chevron, ConocoPhillips, ExxonMobil, Shell, Total and BP.

Drilling waste injection method enables a company to protect its work staff's health and make contributions to local environmental undertakings. Moreover, it also displays the sense of responsibility of a public company.

Preserving blue sky, clean water and suitable land to live for our descendents will forever be the common goal of mankind.
