Cuttings Dryer

Function

A Cutting Dryer can reduce total oil-based mud losses thus decreasing the volume of cuttings, while drilling wells using an oil-based drilling fluids.

 

Applications

Offshore and onshore projects where the recovery of valuable drilling fluid from cuttings, ­as well as recovery of oil-based mud and return to the active system are the priorities.

Problems

More stringent cuttings-discharge regulations have pressured operators and drilling contractors to reduce drilling waste volumes and recover premium products for reuse.

Solutions

The cuttings dryer features a ­state-of-the-art design ­that can process varying amounts of cuttings and fluids, typically up to 60 tons per hour.  Dry solids discharged from the dryer are typically ­<5-6% oil content.

Economics

The cuttings dryer improves ­overall cost-efficiency, producing reduced amounts of extremely dry cuttings for disposal and recovering valuable ­fluid for reuse.  It is effective with oil- and synthetic-base drilling fluids. ­

Environmental

The dryer minimizes waste volumes ­, dramatically reducing disposal costs. In the quest for improved environmental practices, operators need solid-control ­solutions that take liquids/ solids separation to a new level. The cuttings drier incorporates a high-speed vertical­ centrifuge, that achieves maximum liquids/ solids separation in large-volume processing.  This gives ­operators a critical advantage in ­meeting increasingly stringent environmental rules ­for cuttings disposal.

1. The actual capacity of the unit depends on the solids content, density of the feed and working conditions.

2. The amount of residual hydrocarbons in the final product depends on different factors associated with the specific drilling conditions.

 

MOBILE CUTTINGS DRYER

A mobile dryer was designed by the engineers of our company to significantly reduce the amounts of drilling wastes in packaged circulation systems operating in moderate cold and Arctic areas.

The mobile unit is designed as a heated module with the integrated cuttings dryer, effluent tank, circulation and feed pumps, auger-type conveyor, ventilation system, illumination system and control system, installed on the same skids.
