PTC-series Proppant Triaxial cell


The cell functions as an enclosure where cylindrical specimens of resin-coated proppants are exposed to both axial and radial compression forces. To simulate triaxial stresses, a circumferential confining pressure is applied concurrently with an axial load. The specimen is encased in a Viton sleeve and positioned between hardened steel endcaps; this entire assembly is then submerged in oil under confining pressure. A top pore fluid port, located at the upper platen, facilitates the expulsion of fracturing fluids during compression tests. The cell is equipped with a low-friction loading piston specifically for triaxial applications. Additionally, a heating mantle is supplied with the cell to maintain temperature control.
