Fann’s Stirring Fluid Loss Test Assembly is a reliable instrument for measuring fluid loss characteristics of an oil well cement, water-based mud, or fracturing fluid at a set temperature and pressure.
This instrument simulates filtration at downhole conditions in a wellbore and measures the fluid loss. It is equipped with a stirrer to create circulation, a heating jacket to model the bottomhole circulating temperature (BHCT), and a 325 micron mesh screen and filter chamber to replicate the permeable zone. Pressurized nitrogen is applied to achieve the pressure differential between the annular and
formation pressure.
