Zero waste discharge still remains a bit away after going through the previous four steps, therefore solidification, thermal desorption, cuttings reinjection and biodegradation will be utilized to push towards the goal as the last step. Hi-G dryer: KOSUN Hi-G Dryer http://www.kosun.us/drilling-waste-management/hi-g-dryer.html can recover water- and oil-based mud in drill cuttings with fluid phase down below 10% and remarkable reduction on waste discharge cost. It is especially good at managing oil-based drill cuttings.
Hi-G dryer shaker and vertical centrifuge can be introduced as drill cuttings usually take away much drilling mud and thus raise drilling cost. Hi-G dryer manages oil content and water content down to 10% from 30% while vertical cutting dryer lowers oil on cuttings below 5%, to the greatest degree, with small rotary speed and centrifugal filtration. Either of them is effective to recover drilling mud and shrink drilling cost.
The Hi-G dryer shaker is efficient in recovering more oil based drilling fluids and the Oil On Cuttings (OOC) figures is significantly reduced. Another benefit is the elimination of whole mud losses from the traditional shale shaker. So with the use of Hi G dryer shaker in the down stream of mud system, it can allows the shakers to run at their maximum capacity without the concern of the mud loss of the mud system. This is why the Middle East drilling contractor cone to us for the HI-G Cuttings Dryer for their existing mud system.
