n: Refers to eyeholes formed by mud desander in drilling operation.

the unobstructed opening size (diameter, length and width, or other shape factor).

n: 1. a low-pressure area, around which wind flow is counter-clockwise in the Northern Hemisphere and clockwise in the Southern Hemisphere. The term is sometimes used to describe storms occurring in the atmosphere;in the Indian Ocean it is used to designate a tropical cyclone. 2. a device for the separation of various particles from a drilling fluid, most commonly used as a desander. The fluid is pumped tangentially into a cone, and the fluid rotation provides enough centrifugal force to separate particles by mass weight.

n: A device for the separation of solid particles from a drilling fluid. The most common cyclones used for solids separation are a desander or desilter. In a cyclone, fluid is pumped tangentially into a cone, and the fluid rotation provides enough centrifuga

a device that separates cuttings by centrifugal motion of the fluids.

n: The device using centrifugal force produced by fluid rotating to separate solid particle from fluid.

n: See cyclone desander.

n: See cyclone desander.

n: refer to desander

n: a centrifugal device for removing sand from drilling fluid to prevent abrasion of the pumps. It may be operated mechanically or by a fast-moving stream of fluid inside a special cone-shaped vessel, in which case it is sometimes called a hydrocyclone. Compare desiller.

n: A centrifugal device for removing sand from the drilling mud.

devices that typically use centrifugal flow paths to spin solids out of a drilling or circulating fluid.

n: a centrifugal device for removing very fine particles, or silt, from drilling fluid to keep the amount of solids in the fluid at the lowest possible point. Usually, the lower the solids content of mud, the faster is the rate of penetration. The desilter works on the same principle as a desander. Com- pare desander.

n: A hydrocyclone with an inside diameter less than 6 inches. It can remove a large fraction of solids larger than 15–20 microns.

n: fixed ahead of desander, mud shaker directly process the mud fluid returns from the hole.
