Stirred Fluid Loss Tester
Model #: M2-450
Cements are a critical element in the drilling, completion, work-over, and abandonment of wells. A stirred fluid loss tester is used to determine the quantity of fluid that can be lost from a given slurry during placement in the well. The Model 2-450 allows the slurry to be mixed or stirred under simulated downhole well conditions of high temperature and pressure. The ensuing testing per API recommended practices is performed in a single instrument, eliminating the need to transfer the slurry from a dangerously hot consistometer to a static fluid loss tester. It has been proven by comparative testing, that the use of a single instrument for fluid loss testing will result in more predictable and reproducible results, as well as a safer testing environment for the operator.
The CTE stirred fluid loss tester consists of a pressure vessel that is capable of achieving pressures up to 2,000 psig / 13.8 Mpa and temperatures up to 450°F / 232°C. Pressure for the instrument is provided using high pressure gas (nitrogen is preferred). Heat is applied to the cylinder using a heating/cooling jacket and temperature is controlled within 1 degree Celsius. The vessel can be rapidly cooled by circulating cooling water through the jacket after completion of a test. The pressure vessel contains a stirring paddle that rotates at 150 rpm. A standard 325 mesh screen is used as the filter medium to determine the amount of fluid that can be lost from the slurry. A filtrate cooling jacket is included for tests above 200°F / 95°C.
