Final Treatment of Drilling Cuttings

As is known to all and as is the common practice,
in the drilling rig’s drilling mud circle, more and more solids cuttings should
be separated out from the drilling liquid, so that the drilling liquid could be
used in future procedure.

Per different countries and regions, the
requested standard for the discharged drilling cuttings are different. But what
so ever the world share the same opinion that the discharged waste from the oil
and gas drilling could damage the environment and cause long time ruin of the
farm land and surrounding soil. In some countries where the population is
small, the government lays less strict laws for the discharge, and the drilling
cuttings from the solids
control system could be buried in some non-human living place. But in more
and more countries, the law is strict and only solids control is not enough. Therefore,
many solids control manufacturers are providing more solutions as
drilling cuttings waste management systems, and GN Solids Control, as
always, has the leading place.

1. GN VG-dryer waste management system. It is
a system combined with GNCD930C vertical cuttings dryer and GNLW363 Decanter
Centrifuge, used for further treating the drilling cuttings discharged from the shale
shaker, mud cleaner and solids control centrifuge of the solids control
system. Per jobsite test, only the vertical cuttings dryer, the OOC result of
GN Vertical
Cuttings Dryer can be below 5%, and the liquid phase could be better
treated by the decanter centrifuge. For both Vertical cuttings dryer and the
decanter centrifuge, GN has fixed speed and vfd controlled for option.

2. GN Solidification Unit, it is a new
design of GN Solids Control, for feeding the need of some clients whose local
laws are more strict than others. In their countries, the solids from VG-dryer
system are not allowed to discharged directly. Solidification unit could make
the solids cuttings to form like concrete and suitable for other applications.
This is mostly for WBM.

3. GN TDU unit, also new product of GN
Solids Control and mostly used for final treatment of OBM.

GN Solids Control sell a series of solids
control equipment and drilling waste management equipment including mud agitator ,vertical
cuttings dryer , shale shaker , screw conveyor , screw pump , oilfield shale
