1. A fluid flow analysis system, comprising:
a reservoir test sample, comprising:
a core barrel, wherein the core barrel is the outer most portion of the reservoir test sample;
annular fluid, wherein the annular fluid is pressurized to between 1,000 psi and 25,000 psi, and further wherein the annular fluid comprises an amount between 1 liter and 20 liters;
a synthetic tubing, wherein the annular fluid is disposed between the core barrel and the synthetic tubing;
a plurality of supporting layers, wherein the plurality of supporting layers comprises a porous screen, a shrink tubing, and a thin metal sheet, wherein the shrink tubing surrounds the porous screen and the thin metal sheets surrounds the shrink tubing, wherein the porous screen is isolated from the synthetic tubing, and further wherein the synthetic tubing is disposed between the annular fluid and the supporting layers; and
a core sample stack, wherein the core sample stack comprises unconventional, hydraulically-fractured porous media, wherein the core sample stack is cylindrically shaped and comprises five core segments wherein each core segment comprises a permeability less than 10 mill-Darcy and wherein each core segment comprises a plurality of core slots, wherein the plurality of core slots are stacked end-to-end, and further wherein the supporting layers are disposed between the synthetic tubing and the core sample stack;
wherein the annular fluid, the synthetic tubing, the supporting layers, and the core sample stack are disposed within the core barrel;
further wherein the synthetic tubing fully encases the core sample stack and the supporting layers, and wherein the synthetic tubing completely seals the core sample stack; and
further wherein the porous screen is in direct contact with the core sample stack.
