METHOD AND APPARATUS FOR TESTING LOST CIRCULATION MATERIALS WITHIN A PERMEABILITY PLUGGING APPARATUS.

摘要

According to aspects of the present disclosure, an apparatus for testing lost circulation materials (LCMs) within a permeability plugging apparatus (PPA) is described. The apparatus may include a PPA cell cap and an elongated LCM receiver. At least one tubular member may provide fluid communication between the PPA cell cap and the elongated LCM receiver. The at least one tubular member may be sized to accommodate large particulate LCM testing within the PPA. The apparatus may also include a backpressure inlet through the elongated LCM receiver. Providing back pressure within the LCM receiver may extend the temperature and pressure ranges under which the large particulate LCMs may be tested.
