[54] METHOD AND APPARATUS FOR TESTING GEL-BASED LOST CIRCULATION MATERIALS
[57] Abstract: A compression test rig apparatus for determining a mechanical characterization of a gel-based LCM test sample comprising an LCM test cell configured to contain the gel-based LCM test sample, the LCM test cell comprising a cylinder wall defining a cell space volume configured to hold the gel-based LCM test sample, and a floor defining an extrusion hole configured to extrude the gel-based LCM test sample to create an extruded gel; an extruded gel collector configured to receive the extruded gel from the extrusion hole as an extruded gel volume; a perforated disc comprising perforations, wherein the perforated disc is configured to allow the gel-based LCM test sample to pass through the perforations; and a flat foot disc piston in flush contact with the cylinder wall, the flat foot disc piston configured to compress the gel-based LCM test sample at a displacement speed to produce compression data.
