Investigating of Ways to Reduce Wastes Resulting from the Drilling Mud and Providing Appropriate Solutions to Reduce their Environmental Damages

One of the drilling problems of oil wells is remaining of cutting resulting from the drilling which contaminates the environment, especially in the oil-rich regions. In this paper has been tried to discuss reducing ways of these problems. Some of these methods are the use of recyclable mud, surface diffusion, annular injection operation, dispelling into the salt dome and thermal desorption method. Drilling wastes in addition to the environment damages will be very dangerous for humans’ health since chemicals which are extremely harmful to humans are used in drilling mud. Therefore providing ways to reduce or eliminate these wastes are felt more than ever. As we will see with investigating of these methods injection of drilling cutting into the surface formations will be most efficient.
