Waste management, in an oil and gas drilling rig site, is short for the drilling waste management. It is an important regulation to require waste management facilities along with rig sites in order to protect the environment. Because with an effective waste management system, the drilling cuttings could be minimize before discharge and the cause the least harm to surroundings.

Meanwhile, as much as expensive drilling fluids will be recovered, which helps to save money for the drilling contractors.

In Nigeria, there has been a rule that all drilling rigs must have a drilling waste management along with rigs ever since the scandal of some international companies caused years ago for dumping the drilling waste into the surroundings directly. There requested drilling waste management includes:

1. A vertical cuttings dryer. A vertical cuttings dryer is functioning as the drying procedure of a washing machine. It can be regarded as a vertical decanter centrifuge. By a centrifugal force, the liquid phase will be splashed to the inner wall of cuttings dryer though the basket meshes and the solids particles, the dried ones, will be blocked by the same meshes and fall down to the cuttings container below. GNCD930 series vertical cuttings dryers are widely used in Nigeria and other countries, including this client.

2. Decanter centrifuge of high speed. In a waste management system for cuttings, the decanter centrifuge is located after the vertical cuttings dryer. Because after drying the cuttings, there are still some particles inside the discharged fluids from the vertical cuttings dryer, such fine particles should be removed before returning the fluids back to the drilling mud system. GNLW363C-VFD decanter centrifuge is the second to none choice for this purpose.

3. Screw pumps. Both above mentioned 2 equipment need a screw pump. For the vertical cuttings dryer, a screw pump is use for flushing the screen basket to prevent it from blocking, and the most suitable feeding pump for a decanter centrifuge is a screw pump. GN Solids Control has been cooperating with Nestch screw pump for years, and for this client, their system is also equipped by Netsch pump.
