Drilling mud is recirculated throughout the drilling process. As it rises to the surface, it passes through screens that trap the materials from the borehole, before being cycled back into the solids control system that delivers mud to the head of the drill bit. This recirculation process is designed to cut down on waste by reusing as much mud as possible. Depending on the materials being drilled, several screens may be needed to trap the materials, and sometimes the materials themselves are also coated in mud, which means that they will need to be cleaned even after filtration.
Some environmental problems have been associated with drilling mud. Historically, contaminated and dirty mud was dumped in open pits, allowing the natural environment to become polluted. Additionally, very aggressive chemicals are sometimes used to clean materials brought up when filtration was not sufficient. These chemicals can pollute the environment as well, generating a variety of environmental problems. Many companies that conduct drilling retain a compliance engineer who is responsible for monitoring the environmental impact of drilling activities, with the engineer ensuring that the company conforms with the law and its own internal environmental standards.So the solid control and waste management is so important.
