Centrifuges are used to process unweighted and weighted, water-based and oil-based drilling fluids (muds). Mechanical energy is utilized to increase the gravitational force exerted on solids that are present in the mud system. Centrifuges are able to apply over 3,000 G-forces on the liquid/solids mixture, which separates the heavier solids from the lighter solids. Additionally, high G-forces separate fine solids from liquid.
Mechanical separation of solids from the mud system through the use of a centrifuge is a highly-effective means of maintaining proper mud weight and viscosity. When used in conjunction with other solids control equipment, centrifuges enable users to maintain the mud properties within the prescribed range as per the drilling program. Typically, centrifuges are the final processing units in the arrangement of solids control equipment. They are preceded by gas busters, gumbo removal equipment (if utilized), shale shakers, mud conditioners (if utilized), degassers and hyrdocyclones.
NOV Brandt manufactures centrifuges in Conroe, Texas, USA and Aberdeen, Scotland. Centrifuges are typically configured to meet the specifications demanded by the application. They are available individually, in groups or packaged as a component within a complete solids control and waste management solution. Centrifuges are just one of the many solids control and waste management offerings that NOV Brandt supplies to the oil and gas industry. The Brandt Quality Management System is certified to ISO 9001-2000.
