Oil Based Mud Cuttings Dryer and Centrifuge for Overseas Client

If you are familiar with oil service industry, you must know about drilling waste management systems, which is mainly about 3 kinds of treatments: drilling cuttings treatment, drilling fluids treatment and oily sludge treatment. Among which the drilling cuttings treatment was most commonly requested by laws and regulations.

2022.07.14 Drilling Cuttings Dryer

GN Solids Control is a professional solution provider for above mentioned 3 applications, and recently, GN Solids Control just finished the delivery of a drilling cuttings waste management system including 2 decanter centrifuges and 1 vertical cuttings dryer. Normally, for OBM or SBM’s drilling waste management, there should be a vertical cuttings dryer. In fact, the vertical cuttings dryer is specially designed for the OBM’s drilling cuttings, which can reduce the OOC to 5%. After the vertical cuttings dryer, the liquid phase still contains some fine particles. Those particles could be removed by a high speed decanter centrifuge before being returned to the clean mud tank.

In this system there are following features:

  1. A GNCD930 vertical cuttings dryer is located in a container which is easy to be transported by land or by sea. Meanwhile, a well isolated container can keep the vertical cuttings dryer to operate in a comparably warmer condition during winter.
  2. There are 2 sets of decanter centrifuges in this system, one for solids control, the other for the OBM drilling cuttings. Traditionally, there are 4 steps solids control in a solids control system, the shale shaker, desander and desilter cones, then the centrifuge. Nowadays, more and more clients are choosing decanter centrifuge to replace the cyclones and put them directly after the shale shaker (sometimes 2 decanter centrifuges are used for solids control, a middle speed one plus a high speed one, although in this project the client uses 1 set for solids control only). And the 2nd set of centrifuge is used after the GNCD930 for drilling fluids treatment.
