Drilling fluid testing often requires aging of drilling fluid sample. The sample, previously subjected to a period of shear, is allowed to more fully develop its rheological and filtration properties in an aging cell.
The time period needed to more fully develop properties in a drilling fluid varies from as little as several hours (usually 16 hours) to as long as several days. The aging can be done at either ambient or elevated temperatures.
The primary tool for this aging is a roller oven.
