Conrad CCR 1000

The CCR-1000 is a compact and efficient process-water reclaiming installation. Due to its compact dimensions it can be easily used with different types of drilling rigs.

Application possibilities

• On the backside of the drilling rig (hydraulic driven)
• On a trailer (electric driven)
• On a skid (electric driven)

Optionally the CCR can be attached to and detached from the drilling rig by means of a lifting device and hydraulic quick couplings.

Advantages

• Because the process water is direct and constantly filtered it is quickly available again for the drilling process. This eliminates the need for large amounts of process water and large settling tanks.
• Because of this process the cuttings (sand, clay, gravel) are filtered dry, which makes it easier to handle and process. This is, especially on locations with several drillholes, a cost-effective and efficient advantage.
• Because the CCR is a stand-alone installation it can be attached to or installed on an existing rig fairly easy ¹.

Note: ¹ Depends on available hydraulic flow (l/min) and pressure (bar)

During the straight flush drilling process the drill fluid flows into a small container (capacity 200 liter) which is sealed around a small standpipe by means of a rubber sealing flap.

The drill fluid is then pumped to the CCR and deposited on the scalping deck. Here larger pieces of clay and gravel are sifted due to the shaking movement of the shaker. The sifted drill fluid is collected in a container and pumped up again to a hydro-cyclone. Here the water and solids are separated. The water is added to the circulation again.

The solids are then deposited on the primary screen. Here the sand, remaining water and drilling additives are separated. The sand is discharged from the screen deck, the water and additives are added to the circulation. A separate circulation with mixer is also available to add additives to the drill fluid.
