an essentially inert mixture of particles of a particular size range.

n: term applied to many heat resistant and chemically inert fibrous minerals, some forms of which are used in certain drilling fluids. It finds only limited use because prolonged exposure can cause respiratory illness.

n: Usually refers to the fibre of different length made by asbestos. Usually used as block agent in porous
thief formation.

n: A kind of device that processes grained solid material. Applied for processing various drilling fluid treating chemicals, usually for processing coarse and inert bridging material.

n: A kind of vermiculite. Converted by goeschwitzite. Used as inertia block agent.

n: an air- or inert gas-filled device that minimises pressure surges in the output line of a mud pump. Sometimes called a surge dampener.

n: a condition resulting from the formation of gas bubbles in a divers blood or tissues during ascent. Failure to rid tissues of the inert gas may cause a wide variety of symptoms, including pain, nausea, paralysis, unconsciousness, temporary blindness, and even death. Also called the bends.

n: a kinf of inert material with falt shape and small thickness ,usually used as block agent of porosity leaking formation

n: a kind of inertial regime ,it is defined relatively with the peakedness inertial

n: a wheel or disk mounted to spin rapidly about one axis but free to rotate about one or both of two axes perpendicular to each other. The inertia of the spinning wheel tends to keep its axis pointed in one direction regardless of how the other axes are rotated.

n: a wheel or disc mounted to spin rapidly about one axis,but free to rotate about one or both of other two axes.the inertia of the wheel keeps the axis aligned with the reference direction (true north).
