DETAILS
Three objectives were outlined with the subsequent performance data to
be captured during the drilling of this well. During the operation, the
MONGOOSE PRO was operated in the PE mode while the control shaker was operated
in the BE mode, under the same drilling conditions. Real-time comparative data
on flow capacity, cuttings discard rate and cuttings dryness were collected
from both the MONGOOSE PRO and the control shaker during the drilling
operation.
In the 8 ½ in. section, 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). Overall, the MONGOOSE PRO delivered a 33% increase in cuttings discard compared to the control shaker while maintaining the same cuttings dryness.
Although the MONGOOSE PRO shaker displayed the capability to handle a higher fluid capacity and process a higher volume of cuttings, the shaker was able to achieve the same level of cuttings dryness. The MONGOOSE PRO and the control shaker both delivered average cuttings dryness of 68% “dry” and 32% “wet.”

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.
