There are three kinds of drilling fluid, oil based fluids (OBF’s), synthetic based fluids (SBF’s), water based fluids (WBF’s). Every coin have two sides, three ways have there own advantages and disadvantages, but for water based fluids, one important factor is: enviomental friendly, while not delivering optimal performance in more challenging drilling conditions.
Enviomental drilling fluid is water based fluid, no need any biologichal process. Just screening, hydrocycling, decanting, and so on, only mechinical separation.
News from GN Solids Control for some of our clients about enviomental drilling fluid management.
Some photoes about enviomental drilling fluid management systems:
As shown in the picture, the only equipment, related to biologycal is jet mud mixer, and all the drilling fluids without cuttings will recycle and back to the excavation.
Shale shaker is the first phase, and also the most important part of the water based (enviomental) drilling fluid managment.
So do desander and desilter.
