Treatment of Drilling Waste

All wells will be drilled with the
generation of waste , the waste contains different type like drill cuttings ,
waste water , drilling fluids without used and completion fluids . The treatment on waste will be
depending on the drilling fluids type. There are different ways to treat
drilling waste like reduce , reuse , recycle and recover .

Recycle of drilling cuttings is
what GN Solids Control supply , there will be two sets screw conveyor to pick
up drilling cuttings from shale shakers and feed to vertical
cuttings dryer for treatment , then the vertical cuttings dryer will process
drilling cuttings with water or oil content below five percent , the dry
drilling cuttings will be deliveried away for further treatment and fluids
content will be delivery to a small holding tank , there will be a small pump
to pick up recycled drilling fluids and feed to a high speed decanter
centrifuge , the dry solids from centrifuge will be delivery away and clean
fluid can be drop to the clean tank in solids control system .

The vertical cuttings dryer was
used mainly for oil base mud drilling cuttings but the GN new improvement make
it working for water base mud drilling cuttings also . GN Solids ‘s vertical
cuttings dryer is 900 RPM with G force up to 420 G , the super high speed is available
at 1200 PRM with G force up to 750 G for a better separation ability . The
flights on the rotor is hard facing to HRC 65 , longer life than our comptitors
. The individual oil lubrication system with automatic alarm for pressure limit
. The main motor and oil pump motor is interlocked with each other for avoiding
the start of the main motor prior to the start of the oil pump motor .
