GN Nodig Mud Recycling System

Cuttings re-injection is an in situ method for the disposal of driling cuttings and other drilling wastes into a sub-surface stratum

Drill cuttings are slurrified with water and ground down to a pre-determined partical size. The partical size is achieved by passing through a shaker screen. Slurry of hte correct partical size and physical properties is injected via a pump, which is typically of a triplex design, into the well head at a given pressure and down into the pre-detaimined sub-surface injection zone.

No Dig drilling shale shaker is the first phase for mud recycling. Shale shaker performance is very important which is related to bellowing parts:

1) Vibrator Motor quality

2) Shaker deck strenth

3) Shaker screen size and performance

Corrugated screen have up to 125 percent more surfafce area than conventional flat screens. Gravity forces the solids into the corrugated screen’s troughs, thus allowing more fluid to pass through the top of the screen. With conventional flat screens, conductance is reduced as solids form a continuous bed that impedes fluid flow.

GN finished one drilling cuttings tratment system to Australia and will be ready for delivery soon. It contains:

1) Hi G Dryer

2) Centrifuge

3) Auger

4) Mud Tank

The VCCS offers a safe and efficient means for containing drill cuttings after drilling mud recycling at a rigsite. The movement of air through the system allows the collection of drill cuttings and other drilling wastes, such as centrifuge waste and pit cleaning operations.

The system can collect wastes fromthe shakers and centrifuges or it can be configured to collect waste from pit cleaning operations.
