The brand new generation Gn Professional shaker was designed to function both in the capability and Efficiency modes of operation. The Efficiency mode is really a Progressive Ellipticalmotion that creates 6.5 G, as the Capacity mode is really a Balanced Elliptical (BE) motion creating 7.5 G. An immediate comparison by having an earlier generation M-I SWACO shaker was carried out to ensure ale the Gn Professional shaker to supply enhanced performance to satisfy the ever demanding needs of today’s drilling procedures. GN recognized three critical criteria to evaluate overall desander performance: flow capacity, clippings discard rate, and clippings dryness.
A rig in Oklahoma was selected for that mind-to-mind comparison. In Feb 2011, the Gn Professional was installed near the control shaker, using the two linked to a manifold that will carry 9.92 lb/woman oil-based drilling fluid evenly to both models.
Three objectives were layed out using the subsequent performance data to become taken throughout the drilling of the well. Throughout the operation, the Gn Professional was operated within the PE mode as the control shaker was operated within the BE mode, underneath the same drilling conditions. Real-time comparative data on flow capacity, clippings discard rate and clippings dryness were collected from both Gn Professional and also the control shaker throughout the drilling operation.
Test is a result of the well confirmed the highest performance from the Gn Professional drilling waste management. To keep comparative control, both shakers were installed with similar parameters: deck position (0°), screen mesh (API 140), and fluid pond coverage (75% screen coverage). Throughout the 8 ½ in. section in a depth of three,300 foot (1,006 m) by having an ROP of 100 foot/hr (30.4 m/hr), the Gn Professional processed an optimum flow rate of 410 GPM, or 70% from the overall circulating flow rate. Meanwhile, the control shaker processed an optimum flow rate of 293 GPM, amounting to simply 50% from the overall circulating rate. In comparison towards the control shaker, the Gn Professional, while running within the Efficiency mode, averaged a general 28% rise in maximum flow rate, but 20% around the well volume.
Within the 8 ? in. section, the utmost clippings discard rate measured for that Gn Professional shaker was 3,484 lb/hr (1,580 kg/hr) in comparison towards the control shaker’s maximum clippings discard rate of two,400 lb/hr. Overall, the Gn Professional shipped a 33% rise in clippings discard in comparison towards the control shaker while keeping exactly the same clippings dryness.
Even though the Gn Professional shaker displayed the capacity to deal with a greater fluid capacity and process a greater amount of clippings, the shaker could attain the same degree of clippings dryness. The Gn Professional and also the control shaker both shipped average clippings dryness of 68% “dry” and 32% “wet.” Click here to enter the GN next page, where there must be something you want.
