The increased drilling activity in the region is leading to an increased discharge of oil-based mud (OBM), which constitutes the environmental concerns regarding drilling operations. This is owing to the long-term impacts of these wastes, especially in the marine environment, either in the form of toxicity or the creation of anoxic conditions. OBM fluids take a longer period to degrade and the negative effects can last for decades.

The first step in drilling waste management http://www.kosun.us/drilling-waste-management/is to separate the solid cuttings from the liquid drilling mud. In this stage, drilling fluids are processed by separating solids particles from the drilling fluids which called drilling mud solids control and indispensible equipment such as shale shaker, decanter centrifuge and mud cleaners will be used to separate the solids in drilling mud according to the solids parameter size. Once solid and liquid drilling wastes have been separated, companies can use a variety of technologies and practices to manage the wastes. The following will specifically describe the processing procedures in this stage.

When the drilling and completion of waste is conducted during the curing process, the filter or belt transmission device can be transferred via a closed screw conveyor to prevent recontamination. When carrying out a curing treatment, it also need to add the appropriate curing agent in order to reduce the water content to achieve the best curing results.

Besides, Hi-G Dryer, screw conveyor, decanter centrifuge, screw pump and other auxiliary equipment can also be effectively used for drilling waste disposal.
