Definition - What does Shaker Tank mean?
A Shaker Tank, also known as Shale Shaker, 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 Shaker Tank
A shaker tank is considered to be one of the 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 shaker tank 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 removing 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 shaker tank consists of the following components:
- Screen Basket
- Basket Angling Mechanism
