DC Solid control developed an enclosed solids-control system that eliminates the traditional process of shaking fluid and solids and replaces it with an enclosed, vacuum-based filtration process.

Rather than relying on high G-forces, the new system vacuums drilling fluids through a rotating filter belt by using high airflow to separate the cuttings from the fluid. The cleaned drilling fluids are then returned to the active mud system, and the drilled solids are carried forward on the filter belt for discharge or removal.

The high airflow also preempts the need for expensive mud coolers and is particularly applicable in high-pressure/high-temperature wells. The improved separation capabilities lead to better quality mud and fewer chemicals required to maintain its properties.

With more mud recycled back to the fluid system, there is less waste, and that waste is cleaner. The new solution also generates substantially drier cuttings with mud on cuttings being reduced to less than 30 percent of drilled solids, and oil on cuttings as low as 5 percent.
