The MONGOOSE PRO dual-motion shaker effectively handles the ever-changing solids load during the well construction process while delivering cuttings that meet the tightest environmental restrictions. In the capacity mode, the MONGOOSE PRO shaker manages the high cuttings volumes associated with surface hole sections. As drilling progresses and conditions change, the MONGOOSE PRO shaker can be quickly and easily changed to normal mode that allows for longer cuttings retention times in the shaker drying zone. The result includes cuttings that are sufficiently dry and free of contaminants, allowing for full environmental compliance while reducing treatment and disposal costs.
