Drilling Cuttings Management System

What’s the Drilling Cuttings Waste Management system used for?

After being treated by solids control system, the drilling liquid is recycled to the drilling rig and used for drilling again, or to be saved in liquid mud plants for future use. And the drilling cuttings discharged by the solids control system, which means the shale shaker, desander, desilter or their replacement combination mud cleaner, and decanter centrifuge could not be discharged directly, not only because of environmental laws, but also because of cost cutting. So, it is necessary to further treat the drilling cuttings by means of a Drilling Cuttings Management System.

What equipments make the Drilling Cuttings Management System?

A complete standard GN drilling cuttings system is combined by 3 kinds of components as below:

1.      Treating equipments: for further treating the drilling cuttings, there are mainly 2 stages of separation. 1^st is high-G drying shaker or vertical cuttings dryer. 2^nd stage is a high speed centrifuge for extra fine cuttings.

2.      Equipments for transferring the drilling cuttings. In standard design, there are 2 augers, one for collecting drilling cuttings from solids control system and feeding for the 1^st stage treating equipment, the other is to receiving the solids discharges from vertical cuttings dryer. Also, there is a feeding pump for centrifuge, sometimes it is a submersible slurry pump, or a screw pump.

3.      Storage component, of course, it means tank for conserving the liquid phase from the vertical cuttings dryer and feeding for centrifuge by means of a centrifuge feeding pump.

GN has all such above equipments available, designed and manufactured by GN. Each year, GN sells 10s of such systems to both domestic and overseas customers, among which there are famous companies.

How to Choose Suitable Equipments for a Drilling Cuttings System?

GN is familiar with its own designed equipments, knows its function and efficiency. But which equipments to be chosen mostly depends on the customers’ jobsite condition, the mud condition and etc. Although GNCD930C vertical cuttings dryer is proved to be useful for OBM, SBM and WBM, some customer still prefer high-G drying shaker instead for more competitive price.
