Solids control system is very popular used in the oil and gas drilling, HDD and CBM drilling. For oil and gas drilling, in the past, the driller would dig a large pit on the groud to reserve the used drilling fluids. After the drilling cutting sedimented to the bottom of the mud pit, the upper lever drilling fluids would be reused. To some extent, this method could save some drilling fluids, but the enviromental harmful mud pit brought problems for the driller.
With the fast developing of the drilling industry, the traditional mud pit for solids control would not meet the driller’s request for quickly drilling, as the traditional mud pit solids control would cost much time to sediment the drilling cuttings. If the driller start a new drill, then they need new drilling fluids.
In order to enhance the efficience of solids control, reduce the cost for drilling fluids and harm to environment. The technology of pitless was brought into solids control. Pitless solids control system often used in closed loop drilling system. Including the shale shaker, mud cleaner and centrifuge based on the mud tank, the pitless solids control system could circulate the drilling fluids out of the borehole without reserving in the digged sump. The mud tank functioned as the mud pit, after treatment by the solids control equipments, the drilling fluids could be reused without waiting for cuttings sedimentation.
The cuttings discharged from the solids control system and waste management equipments like Verti G cutting drier would be moved to the cuttings drying and holding area bottom built with an impermeable clay bed covered with caliche. After complete drying, the cuttings could be transported for further disposal.
GN Solids Control, the first API certified manufacturer for drilling mud solids control and waste management equipments, could offer the complete pitless solids control system for drilling projects, for more information,please contact with GN Solids Control.
