Description
The FLC-series fluid loss curing cell is engineered to precondition resin-coated proppant packs under elevated temperatures and variable closure stresses before conducting a uniaxial compressive strength (UCS) test. The apparatus features a floating piston accumulator that can be nitrogen-charged to produce the requisite closure pressure. The proppant slurry is confined between this piston and a removable cap on the opposite side, which is equipped with a leak-off port and sand screen. As axial closure is applied, fracturing fluid is permitted to leak off. Typically, a set of 3 to 6 cells, each containing one plug, are run concurrently. These cells are then placed in an oven to facilitate curing of the samples (oven not included). After curing, the plugs are extracted and the samples undergo compressive strength testing using a press. The cells are offered in a broad spectrum of diameters.
