In recent years, the as the demand for environment protection is becoming more and more important, in some countries, there were even conflicts between the local residents and the oil companies or drilling companies. Companies would like to pay money on the disposal of the drilling cuttings, or, they have to face penalty even larger than the cost paid on the drilling waste management solutions.

The drilling waste management solutions for the oil and gas drilling could be divided into 2 groups: the treatment for the drilling cuttings and the treatment for the drilling fluids, the old mud.


The solution suppliers are bringing out several solutions for each group of drilling waste management, for example, in order to treat the old mud, there are several different ways, and among those, the decanter centrifuge and filter press are most prominent 2.

What they have in common?

Both of decanter centrifuge and the filter press need some chemicals to do the job, to separate out the extra fine particles from the drilling fluid.

What are the differences?

The decanter centrifuge uses the high G force generated by high speed rotating of the bowl to separate the solids from the liquid, while the filter press’ working principal is to squeeze the liquid from the solids through some filter with small holes and make the solids phase into a cake.

How are their performances?

Per their treating result, both solutions could treat out 90% solids from the liquid, especially the decanter centrifuge, the percentage is up to 95%. But when take the total cost into consideration the decanter centrifuge clearly wins out because: 1. The centrifuge uses less water than filter press. 2. Less electricity consumption. 3. Less manpower requested. That’s why 8 of ten end users are using decanter centrifuge.
