Powerful, Dynamic HP/HT Filtration Testing The Grace Instrument M2180 Dynamic Filtration LCM Tester features a pressurized, temperature-controlled environment that realistically simulates downhole wellbores. Filtrate medium is available in a variety of porosities and permeabilities to simulate many different types of reservoir formations. When the simulation chamber is filled with drilling fluid under static condition or re-circulation condition, a shear bob simulates the drilling string centrally (or off-centrally) rotating inside of the filtrate medium, shearing fluid. As fluid is sheared, the filter cake deposit becomes visible inside the filtrate medium. The resulting buildup can then be analyzed. Robust back pressure control design minimizes downtime and repair costs. Particle Plugging Test Feature Lost circulation is the uncontrolled flow of whole drilling fluid into a formation with no return to surface, especially within formations that are inherently fractured, cavenous, or have high permeability. Lost circulation can also occur when improper drilling operations damage the mud cake as drilling fluid invades and further damages the formation. The M2180 includes a specialized filtrate medium with an artificial fissure that can be used to perform particle plugging tests to determine the effectiveness of additives, help prevent lost circulation in the filtrate medium, and determine the effectiveness of bridging materials. The M2180 simulates a rotating, off-centric drilling string damaging the filter cake, allowing researchers to measure the performance of bridging materials and devise solutions to minimize fluid loss.
