an estimation of the pumpability of a slurry. Has no direct correlation to viscosity.

n: a thickening-time tester with a stirring appratus to measure the relative thickening time for mud or cement slurries under predetermined temperatures and pressures.

n: A thickening time tester having a stirring apparatus to measure the relative thickening time for drilling fluid or cement slurries under predetermined temperatures and pressures.

a device with rotating paddles, used to check the pumpability and set time of cement slurries.

n: the point at which a cement slurry begins to harden, or set up, and is no longer pumpable.

n: the state that the cement begin to harden and loss the pumpability.

n: the lowest temperature at which a fuel will flow. For oil, the pour point is a temperature 5�F (-15�C) above the temperature at which the oil is solid.

the lowest temperature that a hydrocarbon fluid can be flowed before gelling or turning solid. Related to pumpability.

n: the physical characteristic of a cement slurry that determines its ability to be pumped.

n: the ability that transimites cement slurry by pump.

a measurement of a fluids capability to be pumped. Usually refers to cement slurry and is also called the thickening time.

n: a substance added to cement to prolong the setting time so that the cement can be pumped into place. Retarders are used for cementing in high-temperature formations.

n: A chemical additive used to increase the thickening time of cement slurries or similar fluids that may have a limited pumping time. The increased pressure and temperature typically associated with deep wellbores requires the use of such performance-enhanc

a chemical that slows a reaction. In cementing, retarders slow the set time of the cement and prolong the pumpability of the cement.
