ABSTRACT:
An in-situ linear flow proppant conductivity test cell is provided which allows a downhole fracturing operation to be accurately simulated under laboratory conditions. The test apparatus includes a housing, having pistons therein, a plurality of heating elements, and a packer with a plurality of ports therethrough. Core samples are inserted into the test apparatus and a proppant bed, such as a sand slurry, is introduced into the test cell between the core samples. An external press then provides pressure to the pistons simulating the overburden experienced downhole, while the heating elements simulate downhole temperatures. Pressure, differential pressure, flow rate temperature and fluid loss characteristics can then be measured through the plurality of ports within the packer.
