Case Study: Offshore Abu Dhabi Operating Company achieves higher fluid recovery and longer screen life with SLB's MD-2 shaker

MD-2 Shaker Achieved Higher Volume with Fewer Screens in Less Time than Conventional Shaker

SLB worked with Offshore Abu Dhabi Operating Company, an offshore drilling operator in Abu Dhabi, to address the need to recover more fluid from cuttings, extend screen life, and reliably handle high flow rates on a jackup rig. The company was looking for a shaker solution that could deliver lower mud-on-cuttings while fitting within the rig’s footprint.

SLB deployed the MD-2 dual-deck shaker and evaluated it during drilling with API 140 mesh composite screens. The solution processed 900 galUS/min of fluid with two shakers, kept mud coverage below 50% of the surface area, and required only one screen changeout. Results showed average mud-on-cuttings of 34% by volume and 13% by weight, with performance ranging from 26% to 40% by volume and 9% to 16% by weight, while maintaining full-flow drilling at 40–50 ft/h with no overspill or runoff.
