1 . A system comprising:

a rotating cylindrical chamber comprising a first portion, a second portion, a third portion, a fourth portion, and a fifth portion, with the second portion, the third portion, and the fourth portion located sequentially between the first portion and the fifth portion;

an upper cell section located within the third portion configured to receive a porous media and at least one fluid injected therein, the porous media being selected from the group consisting of carbonate core plugs, sandstone core plugs, sand packs, glass beads, sintered glasses, and a combination thereof;

the second portion including a first porous plate configured to prevent particle migration of the porous media from the upper cell section to the second portion;

a lower cell section located within the fifth portion configured to receive the at least one fluid flowing from the upper cell section through the fourth portion into the fifth portion;

a motorized piston located within the fifth portion configured to pressurize the at least one fluid in the lower cell section;

an inlet port in communication with the upper cell section configured to inject the at least one fluid into the upper cell section;

a heating oven enclosing the chamber configured to heat the porous media and the at least one fluid in the upper cell section, the fourth portion, and the lower cell section; and

a visualization window in communication with the first portion and the second portion configured to allow gas bubble formation and/or fog formation generated from the at least one fluid in the upper cell section to flow therein.

2 . The system of claim 1 , wherein the fourth portion comprises a second porous plate configured to support the porous media in the upper cell section and prevent particle migration of the porous media from the upper cell section to the lower cell section.

3 . The system of claim 2 , wherein the second porous plate comprises a plurality of pores having sizes ranging from about first porous to about 100 μm.

4 . The system of claim 1 , wherein the second portion further comprises a flange configured to partially encapsulate the first porous plate.

5 . The system of claim 1 , wherein the first portion comprises a head configured to form a top section of the chamber.

6 . The system of claim 1 , further comprising an air bath cooling system connected to the heating oven configured to cool the heating oven.

7 . The system of claim 1 , wherein the at least one fluid is selected from the group consisting of water, black oil, volatile oil, gas condensate, wet gas, dry gas, and a combination thereof.

8 . The system of claim 1 , wherein the motorized piston comprises a magnetic stirring system embedded therein configured to homogeneously mix the at least one fluid in the lower cell section.

9 . A method of using the system of claim 1 for analyzing at least one property of a fluid, the method comprising:

obtaining the porous media;

placing the porous media inside of the upper cell section;

injecting the at least one fluid into the upper cell section via the inlet port;

continuously heating the porous media and the at least one fluid in the upper cell section via the heating oven;

flowing the at least one fluid from the upper cell section through the fourth portion and into the lower cell section;

continuously heating the at least one fluid in the fourth portion and the lower cell section via the heating oven;

continuously moving the motorized piston vertically upward towards the fourth portion to pressurize the at least one fluid in the lower cell section thereby allowing the at least one fluid in the lower cell section to flow back through the fourth portion and into the upper cell section;

continuously pressurizing and heating the at least one fluid flowing back into the upper cell section as the porous media absorbs the at least one fluid in the upper cell section via the motorized piston and the heating oven, respectively; and

analyzing the at least one property of the at least one fluid in the upper cell section as the porous media absorbs the at least one fluid in the upper cell section.

10 . The method of claim 9 , wherein the porous media is selected from the group consisting of carbonate core plugs, sandstone core plugs, sand packs, glass beads, sintered glasses, and a combination thereof.

11 . The method of claim 9 , wherein the at least one fluid is selected from the group consisting of water, black oil, volatile oil, gas condensate, wet gas, dry gas, and a combination thereof.

12 . The method of claim 9 , wherein the motorized piston comprises a magnetic stirring system embedded therein configured to homogeneously mix the at least one fluid in the lower cell section.

13 . The method of claim 9 , wherein the fourth portion comprises a second porous plate configured to support the porous media in the upper cell section and prevent particle migration of the porous media from the upper cell section to the lower cell section.

14 . The method of claim 9 , wherein the heating steps comprise continuously and uniformly heating the porous media in the upper cell section, the at least one fluid in the upper cell section, the at least one fluid flowing through the fourth portion, and the at least one fluid in the lower cell section up to about 200° C.

15 . The method of claim 9 , prior to the analyzing step, generating gas bubble formation and/or fog formation from the at least one fluid as the porous media absorbs the at least one fluid in the upper cell section while the at least one fluid in the upper cell section is being continuously pressurized and heated.

16 . The method of claim 15 , wherein the at least one property of the at least one fluid in the upper cell section comprises the gas bubble formation and/or the fog formation.

17 . The method of claim 16 , wherein the analyzing step comprises observing, via the visualization window, the gas bubble formation and/or the fog formation flowing from the at least one fluid in the upper cell section through the section portion into the visualization window.
