Proposal?for the waste management program related to the oily?drilling cutting Great Wall Drilling Company Beijing, China Feb, 2011 1.Introduction Oil and gas wells cannot be drilled without creating waste. However, with good waste management practices, the amount of waste and the toxicity of waste can be reduced. By far, the greatest volume of waste generated in the drilling process is drilled cuttings. The first step and perhaps the best waste management practice is good Solids control equipment, including shakers, mud conditioners, and centrifuges. With our latest technologies in Drilling Waste Management Services we strive to reduce the waste generated at source, during drilling activities to acceptable environmental levels. Our waste management services are based on our Waste Management Hierarchy which governs the way we deal with Solids control and waste disposal in all our drilling activities worldwide. All these services have been structured and designed to meet the increasingly high environmental standards required by the industry when operating in ever more remote and diverse locations. The integration and management of all these services by GWDC’s team of specialists provides the Client with the confidence that any project will be completed in accordance with the highest standards possible. 2.Proposal?for the waste management program related to the oily drilling cutting Treatment of the NABM drilled cuttings will comply with the Waste Management Program and/or Company’s specifications and local requirements.
