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 simulated experimental apparatus used to investigate technology of plugging thief zone.

n: 1. a small portion of a formation obtained by using a core bit in an existing wellbore. See core bit. 2. a spot sample of the contents of an oil or oil product storage tank usually obtained with a thief, or core sampler, at a given height in the tank.

n: The rock sample whose diameter is from 50mm to 100mm ,acquired from bottom hole when core drilling.

n: see thief.

n: in tank sampling, a sample obtained at some specific location in the tank by means of a thief, a bottle, or a beaker.

n: the amount of time required for cement to reach an APIestablished degree of consistency, or thickness. Thickening time begins when the slurry is mixed. thief n: a device that is lowered into a tank to take an oil sample at any depth. The sample will subsequently be used to deter- mine the quality and S&W content of the oil in the tank. v: to obtain a sample of oil from a tank using a thief.

n: The ultimate time that viscosity of cement slurry coming to 10Pa.s


the time that a cement slurry will remain pumpable at temperature and pressure.

to remove a sample from a tank for analysis.

n: a formation that absorbs drilling fluid as it is circulated in the well. Lost circulation is caused by a thief formation. Also called a thief sand or a thief zone. thief hatch n: a lidded opening on top of a stock tank. It allows access for measuring the oil level and for taking samples with a device that is lowered into a tank to take an oil sample at any depth. The sample will subsequently be used to determine the quality and sediment and water content of the oil in the tank.
