Definition - What does Shale Shaker mean?
A Shale Shaker, also known as a shale shaker tank is a vibrating device that is used in a rig solid control system to remove drill cuttings from mud. It has a mesh screen whereby the return mud from the well and drill cuttings flow over when the shaker vibrates. The mud and the solids which are smaller than the mesh size of the screen pass through it for further processing and treatment while the larger solids fall off from the edge of the screen and are discarded.
Petropedia explains Shale Shaker
Shale shakers are considered to be vital components of drilling equipment. These are not only used in the upstream sector of the oil and gas industry, but also in other industries, such as ore mining and cleaning, coal mining and cleaning, etc. A shale shaker forms the very first phase of the solids control system on a drilling rig and is considered to be a primary solids separation tool on a rig. It helps in the removal of the large portions of the rocks/shale known as cuttings from the drilling fluid. Drilling Fluid is a liquid that is used to facilitate the easy drilling of wellbores in the earth's surface. This drilling fluid is an important component that is used to create force in an oil well during oil construction operation. Because the drilling mud stays in contact with the wellbore the entire time of drilling, the operation cannot be completed without it.
A typical shale shaker tank consists of the following components:
