A shale shaker is a device used in drilling rigs to remove large solids, or cuttings, from drilling fluid. It’s the first step in a drilling rig’s solids control system.
How it works
- A shale shaker is a vibrating sieve that shakes drill cuttings across wire mesh screens
- The drill cuttings are separated from the drilling fluid, or mud, and recirculated back into the well bore
- The shaker’s performance can be optimized by adjusting the angle of the frame, the type of movement, and the frequency and amplitude of oscillations
Why it’s important
- Shale shakers are cost-effective and essential for removing solids from drilling fluid
- If shale shakers aren’t used properly, other solids removal equipment won’t work as well
- Removing solids reduces the risk of problems like stuck pipe, lost circulation, and well-control issues
Where it’s used
- Shale shakers are used in many industries, including oil and gas drilling, mining, and coal cleaning
- They can be used for drilling water wells, geothermal wells, and more
