Description

DW High Temperature Aging Cells have been developed to aid in predicting the performance of a drilling fluid under static, high temperature conditions. Recent drilling fluid research has indicated the desirability of applying pressure before heating samples to elevated temperatures in aging tests. For this purpose, DW has available aging cells which can be pressurized with nitrogen or carbon dioxide to a desired pressure to prevent boiling and vaporization of the drilling fluid before it reaches the test temperature. Temperatures and the resulting vapor pressures up to approximately **0°F (**0°C) can be accommodated in aging cells which have been equipped with a valve for pre-pressuring. 
DW High Temperature Aging Cells are designed for testing fluids at temperatures as high as **0 °F. The **0ml are provided for greater volumes of fluid to be tested as higher temperatures, with sufficient space for expansion as a safety factor.
Some cells include a valve and pressure connection for pre-pressuring the cell before heating. The connection to the pressure source is made in the same manner as that used on the HPHT filter presses so that standard nitrogen or CO2 manifolds can be used for this purpose.
