Challenge: The new generation MONGOOSE PRO shaker was engineered to
operate in both the Capacity and Efficiency modes of operation. The Efficiency
mode is a Progressive Elliptical (PE) motion that produces 6.5 G, while the
Capacity mode is a Balanced Elliptical (BE) motion producing 7.5 G. A direct
comparison with an earlier generation M-I SWACO shaker was conducted to verify
the ability of the MONGOOSE PRO shaker to provide improved performance to meet
the ever demanding requirements of today’s drilling operations. M-I SWACO
identified three critical criteria to assess overall shaker performance: flow
capacity, cuttings discard rate, and cuttings dryness.
Solution: A rig in Oklahoma was selected for the head-to-head
comparison. In February 2011, the MONGOOSE PRO was installed next to the
control shaker, with the two connected to a manifold that would carry 9.92
lb/gal oil-based drilling fluid evenly to both units.
Results: Overall, the Mongoose Pro delivered a 33% increase in cuttings discard compared to the control shaker while maintaining the same cuttings dryness.
