In April 2015, GN Solids Control delivered 3 sets high G shaker and 3 sets high speed decanter centrifuge
to a Sichuan customer, these machines have started to operate on the drilling site for Sinopec projects.
The below link is for the working video on GN website.

The High G shaker is always used to treat the WBM waste. When the cuttings came out from the well together with the
drilling fluids, they will be separated out so that the clean liquids can be collected for recycling usage.
Even though, the cuttings still are too wet to be discharged to the ground directly,
so the high G shaker is used to dry the cuttings discharged from solids control equipment shale shaker and cyclones.
After treated by the High G shaker, the liquids will be further treated by the decanter centrifuge.
Detailed process are listed as below.


1.The waste collection container catch the drilling cuttings discharged from the primary shale shakers.
2.GN submersible slurry pump take the waste and feed to GN high G drying shale shaker GNZS594HGE-LD.
3.The mud goes through the screens of the high G drying shaker and drop down to the below tank.
4.The solids discharged from GNZS594HGE-LD drop down to the waste storage tank, and the client
will mix the solids with curing agent and lime powder for solidification treatment.
5.A screw pump will take the liquid from the tank below the drying shaker and feed to GNLW363CG-VFD
decanter centrifuge for reducing the density of the mud.
6.The decanter centrifuge will separate the solids to get clean mud for going back the active mud system for reuse.
The High G shaker is for WBM waste, the vertical cutting dryer is for the OBM waste.
