a container used on logging tools to give temporary protection from the downhole temperature.

n pI: plastics that solidify when first heated under pressure, but whose original characteristics are destroyed when remelted or remolded.

n: a device for assisting in controlling the direction of thermal currents in an indirect heater.

n: a control device used to regulate temperature.

n: a well in a process vessel or line used as a thermometer or thermocouple holder.

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.

n: The apparatus that be used to measure thickening time.

to remove a sample from a tank for analysis.
