Decanting centrifuges for oilfield applications were first introduced in the early 1950s. These early units were adapted from existing industrial decanting centrifuges. In the mid-1960s, a perorated rotor type machine was developed which does not perform like a pure decanter. Commonly called “barite recovery” centrifuges, these early designs were limited in capacity and application.

Today, the decanting centrifuge is even more important part of solids control. In addition, the increased use of low-solids mud and environmental dewatering applications require higher process volumes, greater clarification and solids capacity, and additional fine solids removal. Equipment selection is decided by site specific requirements. Proper system selection is the first step to effective solids control.

GN decanting centrifuge is purpose-built for drilling mud solids control in oilfield applications.
