n: a sandstone in which less than 15% of the total volume is silt and clay.

n: the part of a marine delta that lies farthest from shore. It consists of silt and clay extending well out from the toe of the steep delta face. Such beds grow slowly, out of reach of most of the effects of river current and wave action.

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: refer todesilter

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

n: The process of clearing solid particle whose size is from 2um to 74um from drill 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: the solid particles of cuttings whose size ranges from 2 to 74us in drill fluid
