M-I SWACO Introduces Next Generation Shaker for Increased Fluid-Handling Capacity and Solids Separation

The MONGOOSE PRO provides higher G-forces, higher flow capacity and the ability to maintain expected level of cuttings dryness

M-I SWACO announced today the release of the MONGOOSE* PRO next generation shaker. The shaker operates in two modes—capacity and efficiency—and is designed specifically to meet current and future drilling demands.

The efficiency mode is a Progressive Elliptical motion that produces 6.5 G. The capacity mode is a Balanced Elliptical motion that produces 7.5 G. The patent-pending Progressive Elliptical motion has been field proven on the MD-3* shale shaker, which allows flexibility to handle changing drilling conditions. The Progressive Elliptical motion rapidly separates solids and quickly moves them out of the pool area while increasing the residence time on the drying area, resulting in dryer cuttings.
The MONGOOSE* Pro is a redesign of the PT shaker, which saw its 5,000 unit go into service in the first quarter.

In a head-to-head comparison test between the MONGOOSE PRO and the MONGOOSE PT shakers, the MONGOOSE PRO achieved the same level of cuttings dryness while processing at a maximum rate of 410 GPM, 70% of the overall circulating rate. The MONGOOSE PT shaker processed at 293 GPM, 50% of the overall circulating rate, a 29% increase. The maximum cuttings discard rate measured for the MONGOOSE PRO shaker was 3,484 lb/hr (1,580 kg/hr) compared to the control shaker’s maximum cuttings discard rate of 2,400 lb/hr (1,089 kg/hr).


The MONGOOSE PRO shaker uses the patented DURAFLO* composite screens that seal to the shaker deck thanks to the P-Seal that is integrated into the shaker screen beds and simple wedges that are positioned into place. The composite screen, unlike traditional metal back screens, bends to conform to the arch, creating a tight seal while also providing superior performance, extended service life and increased API screening area.
