Today most major company are using SMB which is environmentally friendly but cost a whole lot more than WBM,while your're able to discharge if in compliance with EPA Rules and Regulations of Federal waters. GOM states 6.9% but most players like Shell, Chevron, Exxonmobile sets there own standards like 5% and below can be discharged.Such as in Brasil Petrobras is looking to go 100% zero discharge. It is not a huge problem in most places but there are some issues there which must be addressed.The funny thing is, Zero Discharge here has been coming up for quite some time and it seemed as though no one was worried about it.

The golden triangle of Brazil, U.S. Gulf of Mexico, and West Africa, which have large scale offshore drilling activities are some of the key markets for zero discharge closed loop system. The Middle East and Asia-Pacific are currently the upcoming markets with growing exploratory activities and increased importance attached to Zero Discharge environmental protection. Consequently, the increasing understanding to decrease environmental hazards, the sustainable development of energy resources, and safe disposal of associated waste continues to encourage the need for drilling waste management services.

For offshore drilling,ship is needed to transport the cuttings to onshore drilling waste management plant for further treatment and disposal .Onshore drilling waste are often treated online by placing drilling waste management system after traditional solids control system or stored in a pit for a period of time and then treated by a drilling waste management service company.
