The drilling waste management is one of the most important chanllenges in the oil/gas exploitation industry. The used drilling mud and cuttings are the main source of drilling waste.There are basically three types drilling mud. Oil-based mud, Waste-based mud,and synthetic based mud. OBM offer advantages over WBM for drilling operation. as a result, OBM are more frequently used in oil/gas drilling. As increased environment protection awareness and more stringent regulation on drilling waste discharge.The global drilling waste management market is therefore expected to grow to approximately $8 billion by 2018.

Currently there are four popular method of drilling waste treatment.

(1) Solidificatin and stabilization, If a polution is below the allowed limit,drilling waste can be solidified. Cement and silica the most popular agents.

2)Cuttings Re-injection. It is successful as well in onshore as in offshore operations. Only a very fine suspension can be injected. So the ball mill or the ultrasonic processor is often necessary to prepare proper particles for the suspension.

3)Thermal method is very useful for cleaning the cuttings.

4)Bioremediation is a more sustainable solution. it can be done in five ways: composting,bioreactors,vermiculture and landfarming.
