The MudCube. From Cubility. |
The MudCube eliminates the traditional process of shaking fluid and solids, delivering improved drilling efficiencies, lower mud consumption, reduced waste volumes and improved HSE.
The MudCube is a compact, vacuum-based filtration system that removes solids from drilling fluids and has been adopted on a number of offshore rigs in in the North Sea, Middle East, Far East and North and South America.
Rather than relying on high G-forces to separate mud and the drilled solids the MudCube drilling fluids are vacuumed through a rotating filter belt using high airflow to separate the cuttings from the fluid more effectively.
The cleaned drilling fluids are then returned to the active mud system and the drilled solids - carried forward on the filter belt - are discharged either directly overboard (if they meet environmental discharge regulations) or to a cuttings handling system.
The improved separation capabilities of the MudCube leads to better quality mud, fewer chemicals required to maintain its properties, more mud recycled back to the mud tanks to be reused for drilling, less waste and a vastly improved working environment. The MudCube also results in improved drilling efficiencies with stable mud properties and a decrease in non productive time (NPT). The remote, automated operations of the MudCube and its’ enclosed system with reduced vibration and noise levels and the elimination of oil vapor also brings considerable workplace benefits, Cubility said.
Located 155km west of Stavanger, Johan Sverdrup is one of the five biggest oil fields on the Norwegian Continental Shelf with expected resources of between 1.7-3 billion boe. Production start-up is scheduled for the end of end 2019 and will consist of four platforms on which the MudCubes will be based.
