Drilling Fluid Management & Disposal
Drilling fluid waste management and solids control of drilling mud related technical and developed situation.
Centrifugal pumps are often referred to as kinetic energy machines. Rotation of the impeller causes fluid within the impeller to rotate at a high velocity, imparting kinetic energy to the fluid.

Most Decanter Centrifuges use the same NEMA design B explosion-proof motors used for centrifugal pumps: either 1500 rpm at 50 Hz or 1800 rpm at 60 Hz. Decanter Centrifuges may draw up to seven times the full-load current for approximately 15 seconds at startup. It is considered good practice to limit centrifuge startups to two starts per hour to protect the motor because the current draw closely approaches the limit.

Other than hydrocyclone and manifold plugging, improperly sized or operated centrifugal pumps are by far the greatest source of problems encountered with hydrocyclones. Centrifugal pump and piping sizing are critical to efficient hydrocyclone operation. A pressure gauge should be mounted on the hydrocyclone inlet manifold.

Shale shaker screening is dependent on a constant flow of drilling fluid
with cuttings. The fluid must pass through the screen, and the cuttings
must either pass through or be rejected by the screen. Gas cutting in the
drilling mud can have up to three different effects that upset the screening
process.
1. Gas heading can cause volume surges in the mud flow that exceed
the ability of the screen to handle fluid flow. This is usually from gas,
intermixed in the mud, rapidly expanding at the surface and pushing
large surges of drilling fluid out the flowline. Gas busters and gas
separators are the solutions to this problem.
