M-I SWACO introduces new dual-deck shale shaker

HOUSTON -- M-I SWACO, a Schlumberger company, today announced the introduction of the MD-2 dual-deck shale shaker. When combined with DURAFLO composite screens, the MD-2 shaker provides optimal solids control performance for drilling applications.

The development of the MD-2 shale shaker was the result of customers’ requests for a durable mid-range shaker suitable for both onshore and offshore applications. M-I SWACO developed the dual-deck shale shaker using the proven design of the offshore-suited MD-3 triple-deck shaker, and also utilizes design elements from the onshore-suited MONGOOSE PRO shale shaker. Design validation for the MD-2 shaker was conducted at the SWECO manufacturing facility in Florence, Kentucky, United States.

In a field trial in South Texas a customer was drilling a 22-in. hole using two conventional shakers, but due to capacity limitations there was a low rate of penetration (ROP). To optimize the solids control performance, one MD-2 shaker was provided, which processed drilling fluid at a rate of 658 gal/min , or more than twice the two conventional shakers combined. Additionally, the MD-2 shaker handled 100% of the flow throughout the top hole section, thereby maximizing flow rate and maintaining the desired ROP.

The small footprint of the MD-2 dual-deck shale shaker makes it ideal for space-restricted onshore and offshore drilling rigs where high-capacity separation efficiency and operational flexibility are needed. In addition, the combination of the MD-2 shaker and DURAFLO composite screens provides nearly double the capacity of a standard single-deck shaker.
