The study of History is the beginning of wisdom. – Jean Bodin
The actual money saved by using correct drilling fluids processing is difficult to document. Most operators regard the cost of drilling wells as proprietary information.

Today’s shale shakers must be capable of maintaining optimum fluid properties to maximize drilling efficiency.Joe Bacho
Define Shale Shaker
Shale shakers are components of the solids control systems. Shale shaker mainly used in the oil and gas drilling industry. Shale shaker is the first phase of a solids control system on a drilling rig, and are used to remove large solids (cuttings) from the drilling fluid (“mud”).

Shale shaker is the main solids removal equipment. Today, offshore and onshore drilling projects where more effective fluids/solids separation is required in addition to the reduction of costs related to shale shakers performance.

The gypsum-salt formations are complex in drilling fluid. The gypsum-salt formations are characterized by salting-in property, plastic creep and anisotropy. Meantime, the rheological properties of drilling fluids become worse when contaminated by high pressured brine in the gypsum-salt formations. In the process of drilling operation in the long-section gypsum-salt formation, reasonable mud weight and good rheological properties of drilling fluids should be used to ensure the safety drilling in this complex formation. The main matters needing attention is as follows:
