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

n: a record made each day of the operations on a working drilling rig and, traditionally. phoned or radioed in to the office of the drilling company every morning. Also called morning report. See drillers report.

n: One of report of drilling operation. The original record of drilling operation recorded by day.
